0
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
