Both are cells containing
a membrane, cytoplasm, DNA, RNA, ribosomes, proteins
, a means of producing ATP (probably from glucose), a method of internal transport, and a method of reproduction (interestingly, protists retain the ability to reproduce asexually, like bacteria, although many can also reproduce sexually via …
Which organelles do bacteria and protists have in common?
Both bacteria and protists have
cell membranes
made of chemicals called phospholipids. A phospholipid in a bacterium or a protist has a water-soluble group at one end and a water-insoluble tail at the other, so the cell membranes of bacteria and protists are constructed from a bilayer of phospholipids.
Bacteria and Protists are both
important living organisms
which compromise a major part of our surroundings. … Protists are only found in moist surroundings, while bacteria are found everywhere. Bacteria are single celled while protists can be single celled or multicellular.
What characteristics do the bacteria and protists not have in common?
Bacteria
lack a nucleus, mitochondria, chloroplasts and organelles
. Protists can either be single-celled or multiple called. They contain a nucleus surrounded by a nuclear membrane. The DNA or genetic material of a bacteria is not surrounded by a protective membrane known as a nuclear membrane.
What do viruses and protists have in common?
While viruses cannot replicate without a host cell, many reproduce very fast after infection. … They are also simple structures, with the Protists being the most complex — protists have a
full protein nucleus —
and the Virus the most simple — viruses are just a protein strand with instructions to replicate.
Why do protists and bacteria benefit us?
Why? Plant-like
protists produce almost one-half of the oxygen on the planet through photosynthesis
. Other protists decompose and recycle nutrients that humans need to live. All protists make up a huge part of the food chain.
What is unique about protists?
Protists vary greatly in organization
. 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. …
Is a protist a bacteria?
Bacteria are single-celled microbes and
are prokaryotes
, which means they’re single-celled organisms lacking specialized organelles. … In contrast, protists are mostly single-celled eukaryotic organisms that are not plants, fungi, or animals.
What are the similarities between protozoa and bacteria?
Protozoa (pro-toe-ZO-uh) are one-celled organisms, like bacteria. But they are bigger than bacteria and contain a nucleus and other cell structures, making them more like plant and animal cells. Protozoa
love moisture
.
Is bacteria smaller than protists?
Protists are eukaryotic, but diverse kind of organisms placed in a single kingdom. Largest protists are algae, which are really huge while
largest bacteria are less than 1mm in size
.
What is one difference between you and a protist?
In short,
human cells
are usually highly specialized based on function and tissue type while protist cells are, while also eukaryotic, still simple.
What are the similarities between protists and animals?
Animal-like Protists
Protozoa are single-celled eukaryotes that share some traits with animals.
Like animals, they can move, and they are heterotrophs
. That means they eat things outside of themselves instead of producing their own food. Animal-like protists are very small, measuring only about 0.01–0.5mm.
What do protists have in common?
Like all other eukaryotes, protists have
a nucleus containing their DNA
. They also have other membrane-bound organelles, such as mitochondria and the endoplasmic reticulum. Most protists are single-celled. Some are multicellular.
How are protists different from viruses?
Whereas viruses as pathogens of humans and livestock have been intensely studied for a century, much less is known about the majority of viruses – especially those that infect microbes. Protists are
unicellular eukaryotes and harbor a wide spectrum of viruses
, from small RNA viruses to giant DNA viruses.
What do protists plants fungi and animals have in common?
Animal-like protists, which are heterotrophs and have the ability to move. Plant-like protists, which are autotrophs that photosynthesize. Fungi-like protists, which are heterotrophs, and they have
cells with cell walls and reproduce by forming spores
.
What are the disadvantages of protists?
The major negative about protists is that
some cause diseases
, both in humans and in other organisms. Examples are amoebic dysentery, meningo-encephalitis, malaria, toxoplasmosis, and African sleeping sickness.
