What does the cell theory state

-all living things are composed of one or more cells
-cells are the basic unit of structure and function
-cells only come from existing cells

1

The surface area of a cell can only be so big because..

They won't function properly

2

Prokaryotic cell

-no membrane bound organelle
-no nucleus

3

Example of prokaryotic

Bacteria

4

Eukaryotic cells

The cells that make up most living things

5

An example of a eukaryotic cell is

Cells inside humans

6

What does the cell membrane do

Surround the cell and gives it support and shape

7

What is the cell membrane also called

Plasma membrane

8

The cell membrane is

Selectively or semi permeable

9

What does semi permeable mean

The cell membrane is able to control what goes in and out of the cell

10

The cell membrane is a

Lipid bilayer

11

What is the lipid bilayer made of

Membrane proteins

12

What is the brain of the cell

Nucleus

13

Spherical structure, usually located in the center of the cell

Nucleus

14

Function of nucleus

Making nucleic acids and directing the cells activities

15

The nucleolus

Middle of the nucleus

16

The nucleolus makes

Ribosomes

17

Nucleoplasm

Liquid inside the nucleus

18

To what is the nucleolus rich in

Proteins and chromatin

19

The nuclear membrane is also referred to as

The nuclear envelope

20

Nuclear membrane

Double membrane that is semi permeable

21

How is the nuclear membrane semi permeable

Pores

22

The most numerous of organelles

Ribosome

23

Function of ribosomes

Making proteins

24

Ribosomes can exist in two ways

-Free floating in the cytoplasm
-Attached to the ER

25

System of membranes forming folded sacs and tunnels

Endoplasmic reticulum

26

Two types of ER

Rough
Smooth

27

What is rough ER responsible for

Protein production

28

What is smooth ER responsible for

Produces lipids and area of detoxifying for the cell

29

Stack of membranes filled with fluid and dissolved substance

Golgi complex
