0

• Regulates what enters and leaves the cell
• Helps to provide protection and support

Cell Membrane

1

• Makes up the Cell Membrane
• Double layered sheet

lipid bilayer

2

In addition to lipids, most cell membranes also contain ____ + ____ embedded in the bilayer

proteins and carbs

3

proteins form ____ + _____ to move material across the cell membrane

channels and pumps

4

Carbs help cells _____

identify each other

5

•Lies outside the cell membrane
• supports and protects the cell
• found in plants, fungi, algae etc.,

Cell Wall

6

• Some materials pass through, while others may not
• regulates chemical composition
• maintains homeostasis

Selectively permeable

7

In plant cells, the Cell Wall is made of ______?

Cellulose

8

Movement of molecules from a region of high concentration to a region of low concentration

diffusion

9

No energy used

passive

10

energy used

active

11

diffusion of water across a selectively permeable membrane

osmosis

12

increased pressure resulting from osmosis

Osmotic pressure

13

• Same concentration
• No net gain or loss of water

Isotonic Solution

14

•Lower concentration
• More Water Outside the cell
• water moves into the cell

Hypotonic solution

15

• Higher concentration
• More water in the cell
• Water moves outside the cell

Hypertonic solution

16

Cell membrane has protein channels to assist molecules in crossing the membrane

Facilitated Diffusion

17

Two things that don't require energy

Facilitated Diffusion
Diffusion

18

Process by which cells move materials against concentration gradient

Active Transport

19

Process where energy is required

Active Transport

20

Transport by which the cell envelopes the materials it wants to take in, usually very large molecules

Endocytosis

21

small amounts of liquid engulfed

pinocytosis

22

extensions of cytoplasm surround particle, package it, and engulf it (amoeba)

Phagocytosis

23

transport of material out of the cell by means of a vesicle

exocytosis

24

cells develop in different ways to perform different tasks called

cell specialization

25

A group of cells which are structurally similar and perform the same function

tissues

26

groups of tissues that work together to perform a specific function

organs

27

groups of organs that perform a specific task

organ system
