Cytoskeleton

Answer 16

Supporting structure and transportation system

Question 17

Microfilaments

Answer 17

(Cytoskeleton) Flexible Framework that supports the cell

Carry out cell movement

Question 18

Microtubules

(Cytoskeleton) Maintain cell shape

Carry out cell movement

Question 19

Cell Wall

Answer 19

Only in plants

Support and structure

Question 20

Cell membrane

Answer 20

Controls movement in and out of cell

Think flexible barrier

Question 21

Endocytosis

Answer 21

Taking material into the cell by unfolding the cell membrane

Question 22

Phagocytosis

Answer 22

Method of taking in food

Question 23

Pinocytosis

Answer 23

Cells take up liquid from the environment and form vacuoles

Question 24

The Cell Theory

Answer 24

All living things are composed of cells
Cells are the basic unit of structure and function in living things
New cells are produced from existing cells
(Cells are the smallest unit capable of all life functions)

Question 25

Prokaryotes

Answer 25

Have genetic information that is not contained in the nucleus
Generally smaller and simpler than eukaryotes

Question 26

Eukaryotes

Answer 26

Genetic material is contained in the nucleus where it is separated from the rest of the cell
Generally larger and more complex than prokaryotes

Question 27

Unicellular

Answer 27

Do every action associated with living things

Single-celled organism

Question 28

Multicellular

Answer 28

Develop in order to do specialized functions

Multi-celled organism

Question 29

Level of Organization

Answer 29

1. Individual Cells
2. Tissues
   Similar cells are grouped into units called tissues.
   Tissues are a group of cells that perform a particular function.
3. Organs
   Many groups of tissues work together as an organ.
4. Organ Systems
   A group of organs that work together to perform a specific function is called an organ system.
