How did life forms originate and become complex?
Eukaryotic cells also acquired other organelles, such as the endoplasmic reticulum, where proteins are made, and the Golgi apparatus, which dispatches them to their destination, possibly by infolding of their cell membranes. All of this set the scene for the emergence of complex, multicellular life forms.

Which of the following is are properties of life quizlet?
Property of Life: Every organism takes in energy, converts it to useful forms, and expels energy . Property of Life: Each living thing has a complex but well-organized structure. Property of Life: All living organisms consists of cells. Some have one cell, but others have trillions.
Which of the following is the most important property of life?
A living organism has the following characteristics; growth, response to environment, made of cells, maintain homeostasis , passes traits to offspring, made up of cells, change, breathe and metabolism.

What is Organisation of cell?
By definition, cellular organization is the components that make up the cell and how they are arranged inside it . Each component called an organelle, performs a specific function vital for the cell. This page will explore the basic functional components of the cell and cell shape and its size.
Why is the level of organization in living things important?
An organism is made up of four levels of organization: cells, tissues, organs, and organ systems. These levels reduce complex anatomical structures into groups; this organization makes the components easier to understand .
How do centrosomes help the cell?
The centrosome is an important part of how the cell organizes the cell division . ... And the centrosomes organize the microtubules, so it’s called the microtubules organizing center. The centrosomes duplicate before cell division, so they then help to organize the microtubules and the cell division process.
How are multicellular organism organized?
The body of a multicellular organism, such as a tree or a cat, exhibits organization at several levels: tissues, organs, and organ systems . Similar cells are grouped into tissues, groups of tissues make up organs, and organs with a similar function are grouped into an organ system.
Is cellular organization a characteristic of life?
Fortunately, biologists have developed a list of eight characteristics shared by all living things. ... Those characteristics are cellular organization, reproduction, metabolism, homeostasis, heredity, response to stimuli, growth and development, and adaptation through evolution.
What level of organization would the kidney represent?
After tissues, organs are the next level of organization of the human body. An organ is a structure that consists of two or more types of tissues that work together to do the same job. Examples of human organs include the brain, heart, lungs, skin, and kidneys.
What is the 6 level of organization?
Name the six levels of organization of the human body. Chemical, cellular, tissue, organ, organ system, organism .
What level of organization is cartilage?
| A B | Examples of this level of organization include cartilage and blood in animals, and xylem and phloem in plants. tissue | Examples of this level of organization include red and white corpuscles, platelets, and neurons. cell |

What 4 Things do both eukaryote and prokaryote cells contain?
Both prokaryotic and eukaryotic cells have structures in common. All cells have a plasma membrane, ribosomes, cytoplasm, and DNA . The plasma membrane, or cell membrane, is the phospholipid layer that surrounds the cell and protects it from the outside environment.
How does life evolve based on emerging pieces of evidence?
New research shows that the close linkage between the physical properties of amino acids, the genetic code, and protein folding was likely the key factor in the evolution from building blocks to organisms when Earth’s first life was emerging from the primordial soup. ...
Changes in populations accumulate over time; this is called evolution. The fossil record shows us that present day life forms evolved from earlier life forms. Beginning about 540 million years ago more complex organisms developed on Earth. ... Many types of organisms that once lived are now extinct.
Are archaebacteria Autotrophs?
Archaea can be both autotrophic and heterotrophic. Archaea are very metabolically diverse.
How bacterial and archaeal DNA is organized?
Archaea and Bacteria generally have a single circular chromosome – a piece of circular, double-stranded DNA located in an area of the cell called the nucleoid. In contrast, many eukaryotes have multiple, linear chromosomes. ... The composition of the cell wall differs significantly between the domains Bacteria and Archaea.
What environmental factors influenced the evolution of early life forms?
Competition for space, food, and shelter as well as increased predation created additional natural-selection pressures. Fossil records indicate mass extinctions and a major change in genetic diversity at this time.
Which cell is more organized?
1.2: Cellular Organization – Prokaryotic and Eukaryotic Cells . Briefly describe why, in terms of differences in cell size, a eukaryotic cell is structurally more complex and compartmentalized than a cell that is prokaryotic.
Who discovered the first living cell?
The cell was first discovered by Robert Hooke in 1665, which can be found to be described in his book Micrographia. In this book, he gave 60 ‘observations’ in detail of various objects under a coarse, compound microscope.

Which type of organization is found in only living beings?
Answer: There are various levels of organizations found in living beings. These organizations are arranged in from the most complex to the simplest form. Organelle , cells, tissues, organs, organ systems, organisms, populations, communities, ecosystem, and biosphere.

What are the levels of organization in which biodiversity exists explain what each level contains?
Usually three levels of biodiversity are discussed— genetic, species, and ecosystem diversity . Genetic diversity is all the different genes contained in all individual plants, animals, fungi, and microorganisms. It occurs within a species as well as between species.
What is the correct order of levels of organization from smallest to largest?
