Examples of protists include
algae, amoebas, euglena, plasmodium, and slime molds
. Protists that are capable of photosynthesis include various types of algae, diatoms, dinoflagellates, and euglena. These organisms are often unicellular but can form colonies.
What best describes the offspring of protists?
Asexual binary fission in protists is one major mechanism of reproduction. A single-celled protist’s body is separated into two parts, or halves. After this process, there is no longer a “parental” body, but a pair of offspring. These offspring are called
daughter nuclei
.
How do protists reproduce?
Protists reproduce by a variety of mechanisms. Most undergo some form of asexual reproduction, such as
binary fission
, to produce two daughter cells. In protists, binary fission can be divided into transverse or longitudinal, depending on the axis of orientation; sometimes Paramecium exhibits this method.
Which protist reproduces sexually and asexually?
Protist Reproduction
Many have both asexual and sexual reproduction. An example is a protist called
Spirogyra
, a type of algae, shown Figure below. It usually exists as haploid cells that reproduce by binary fission.
Which are characteristics of all protists?
-
They are eukaryotic, which means they have a nucleus.
-
Most have mitochondria.
-
They can be parasites.
-
They all prefer aquatic or moist environments.
How do protists reproduce quizlet?
Most Protist reproduces
asexually using binary fission
, where a one Protist splits into 2 identical cells. Some Protist can reproduce by multiple fission where one Protist produces more than two other cells. Some Protist can reproduce sexually congregation where two cells are joined and trade genetic information.
Which type of reproduction occurs in protists?
Cell division in protists, as in plant and animal cells, is not a simple process, although it may superficially appear to be so. The typical mode of reproduction in most of the major protistan taxa is
asexual binary fission
.
How do protists reproduce for kids?
Protists can reproduce
asexually through binary fission
, one nucleus divides; multiple fission, many nuclei divide; and budding. During both types of fission the organism replicates its nucleus and divides to form new organisms. ... They can, however, also reproduce by sexual reproduction.
Which protists reproduce asexually?
Rhizopoda reproduce most often using binary fission. Spirogyra, an algal protist, reproduce through conjugation. The one exception to this is the
euglena
division of algal protists, which does not reproduce sexually, only asexually by dividing longitudinally.
What protists reproduce asexually?
Actually protists produce both ways.
Animal-like amoebas and plantlike Euglena
reproduce asexually. Others reproduce sexually. To reproduce sexually, it requires 2 parents.
Do protists have organelles?
Like all eukaryotic cells, those of protists have a characteristic central compartment called the nucleus, which houses their genetic material. They also have
specialized cellular machinery called organelles
that execute defined functions within the cell. ... The plastids of some protists are similar to those of plants.
What protists produce spores?
Apicomplexans
are a phylum of parasitic protists that form spores as part of their life cycle. Only one genus of apicomplexans that are mutualistic, or beneficial to their hosts, are known. Apicomplexans are eukaryotic, meaning that they have a nucleus and other organelles.
Are protists motile or nonmotile?
While many protists are capable of motility, primarily by means of flagella, cilia, or pseudopodia,
others may be nonmotile for most or part of the
life cycle. Resting stages (spores or cysts) are common among many species, and modes of nutrition include photosynthesis, absorption, and ingestion.
Which statement describes plant-like protists?
Plant-like protists are autotrophs. This means that they produce their own food. They perform photosynthesis to produce sugar by using carbon dioxide and water, and the energy from sunlight, just like plants. Unlike plants, however, plant-like protists do not have true stems, roots, or leaves.
Which of the following characteristics describes all protists quizlet?
All protists have the following characteristics:
one or many celled organism, lives in moist or wet surroundings
, and they have eukaryotic cells-cells that have a nucleus and other internal, membrane-bound structures. Compare and contrast the characteristics of animal-like, plantlike, and fungus like protists.
What characteristics might make you think a protist could be pathogenic?
Protists that are
heterotrophic
are more likely to cause disease than autotrophic protists. Protists that are missing certain organelles or that are nonmotile are more likely to be parasitic or pathogenic than those that have all of the usual organelles and those that are motile.
Which group of protists reproduces asexually by releasing spores?
Protists differ from other living things in many ways. Look at Figure 1 to see a variety of protists. Most protists are single-celled organisms. For example, all protists are
eukaryotic
(yoo KAR ee AHT ik), which means that their cells each have a nucleus.
Do protists reproduce by mitosis?
Reproduction in protists is found to be of two types,
asexual reproduction by mitosis or sexual reproduction by meiosis
. They reproduce by asexual means under severe conditions while the sexual method of reproduction is extremely rare. The organisms include amoeba, Plasmodium, and Euglena.
Which description best supports the Endosymbiotic theory of organelles quizlet?
Which description best supports the endosymbiotic theory of organelles?
Eukaryotic cells acquired mitochondria and plastids by engulfing free-living bacteria and developed a symbiotic relationship with them
. Mitochondria were derived from aerobic bacterium while choloroplasts were derived from cyanobacterium.
What is the purpose of protists?
Protists function at several levels of the
ecological food web
: as primary producers, as direct food sources, and as decomposers. In addition, many protists are parasites of plants and animals that can cause deadly human diseases or destroy valuable crops.
Which reproductive process occurs among the protists microbial eukaryotes )?
In fission (or binary fission)
, a parent separates into two or more individuals of about equal size. This type of reproduction is common among single-celled organisms including bacteria, archaea, and unicellular eukaryotes, such as protists and some fungi. The single cell divides into two daughter cells.
What is protist science kids?
Protists are organisms that are part of the
biological kingdom
called the protista. These organisms are not plants, animals, bacteria, or fungi. Protists are a very diverse group of organisms. They are basically all the organisms that don’t fit into the other groups.
What are protists ks3?
Protoctists are
microscopic single-celled organisms
. Some protoctists, such as Amoeba, have features like an animal cell. Others, such as Chlorella, have chloroplasts and are more like plants.
How do prokaryotes reproduce?
How do prokaryotes reproduce? Prokaryotes reproduce through
a cell division process called binary fission
. Like mitosis in eukaryotes, this process involves copying the chromosome and separating one cell into two.
How do protists grow and develop?
Slime molds are an example of sexually reproducing protists. They give
off spores
, which grow to the amoeboid form. They are then fertilized and undergo mitosis to form the feeding plasmodium stage. Finally, they mature and eventually give off spores of their own.
In which type of reproduction 4 haploid daughter cells are formed?
The purpose of meiosis is to produce gametes, or sex cells. During meiosis, four daughter cells are produced, each of which are haploid (containing half as many chromosomes as the parent cell).
How does fungus like protists reproduce?
Fungus-like protists are molds. They are absorptive feeders on decaying organic matter. They resemble fungi, and they reproduce
with spores as fungi do
.
Which protists are Colonial?
-
a) some choanoflagellates.
-
b)Volvox (hollow spherical ‘colonies’ that may be quite complex)
-
c) ‘swarming’ ciliates & sarcodines (slime molds) that alternate between isolated cells and complex stalked sporocarps.
Are protists multicellular or unicellular?
protist, any member of a group of diverse eukaryotic,
predominantly unicellular microscopic organisms
. They may share certain morphological and physiological characteristics with animals or plants or both.
What is bacterial reproduction?
Bacteria reproduce primarily by
binary fission
, an asexual process whereby a single cell divides into two. Under ideal conditions some bacterial species may divide every 10–15 minutes—a doubling of the population at these time intervals.
Which protist can reproduce using the process of fragmentation?
Certain protozoa,
algae, molds
break into pieices and fragmentation is an assexual process of reproduction where each of these pieces form into a new organism.
Which protists use flagella to move?
Zooflagellates
are a third type of protists. They are animal-like and move by using flagella. Flagella are whip-like structures that spin quickly, working like a boat’s propeller to move the organism through water.
What type of organelles do protists have?
The organelles in protists include things like
ribosomes
, which are the organelles responsible for synthesizing all the proteins the protist will need; mitochondria, which are the organelles responsible for turning food into energy the cell can use; and chloroplasts, which are the organelles that are able to capture ...
Are protists Autotrophs or Heterotrophs?
Protists get food in many different ways.
Some protists are autotrophic, others are heterotrophic
. Recall that autotrophs make their own food through photosynthesis or chemosynthesis (see the Photosynthesis concepts). Photoautotrophs include protists that have chloroplasts, such as Spirogyra.
What are structure of protists?
Protist cells may contain
a single nucleus or many nuclei
; they range in size from microscopic to thousands of meters in area. Protists may have animal-like cell membranes, plant-like cell walls, or may be covered by a pellicle.
How does reproduction occur in fungi?
Most fungi
reproduce by forming spores
that can survive extreme conditions such as cold and lack of water. Both sexual meiotic and asexual mitotic spores may be produced, depending on the species and conditions. Most fungi life cycles consist of both a diploid and a haploid stage.

How does plant-like protists reproduce?
Some plant-like protists replicate using
binary fission
, which is just dividing in two. Still others reproduce by making asexual spores, which spread out and form new individuals. Finally, fragmentation is yet another way of asexual reproduction in plant-like protists.
Which statement describes a characteristic that euglena a protist share with plants?
Euglenoids are considered to be
plantlike protists because they contain chloroplasts and are capable of making their own food
