Cell Membrane

In all cells
Protects the cell and creates a barrier between the inside and outside. Controls what enters and exits the cell

1

Cell wall

In plants
Made of cellulose
Thick rigid wall located just outside the cell membrane
Keeps plant standing

2

Cytoplasm

In all cells
Jelly like liquid inside the cell membrane
Contains the organelles and is the location of many chemical reactions controlled by enzymes

3

Nucleus

In all cells
Control center of the cell and contains DNA

4

Nuclear envelope

In all cells
Surrounds the nucleus for protection

5

Nucleolus

In all cells
Special region in the nucleus where ribosomes are made

6

Ribosomes

In all cells
Proteins that make proteins free or attached
Free in cytoplasm
Attached in the rough ER

7

Rough ER

In all cells
Always near nucleus
Makes proteins and other cell products for export out of the cell
Studded with ribosomes

8

Smooth ER

In all cells
Makes cell membrane
Detoxify drugs
Has many enzymes, NO lysosomes

9

Golgi Apparatus

In all cells
Collects, modifies, and ships cell products
Receives cell products from the endoplasmic reticulum

10

Transport Vesicle

In all cells
Small membrane bound compartments
Transports compounds around the cell

11

Lysosomes

In animal cells
Contains digestive enzymes
Surrounded by a double membrane
Digests food and other cells

12

Vacuole

In all cells
Stores water, good, nutrients, and cell products

13

Turgor pressure

Outward pressure of cytoplasm against a cell wall. Allows plants to stand up

14

Chloroplast

In plant cells
Converts sunlight into food

15

Mitochondria

In all cells
Converts food into energy

16

Cytoskeleton

In all cells
Skeleton of the cell
Provides structure, shape, and movement

17

Centriole

In animal cells
Involved in cellular reproduction

18

Cilia

In all cells
Have small hair like projections
Provide movement

19

Flagella

In all cells
Whip like cell
Provides movement

20

Pinocytosis
Active or passive?

Ingestion of liquids
Active transport

21

Equilibrium

Concentration of solute is equal on both sides of the membrane

22

Passive Transport

No energy required, down gradient

23

Hydrophobic tails

Part of the interior of the membrane

24

Exocytosis
Active or passive ?

Material removed from the cell
Active transport

25

Diffusion
Active or passive?

Movement of molecules from a greater to a lesser concentration
Passive transport

26

Facilitated diffusion
Active or passive?

Movement of molecules down a gradient with the help of a carrier protein
Passive transport

27

Osmosis
Active or passive ?

Movement of water molecules across a membrane
Passive transport

28

Selectively permiable

Allows only certain things in or out

29

Hypertonic

Solution that causes cells to shrink
Has higher percentage of solute
