cells

Question 1

cell membrane

Answer 1

• permeable allows solutes to move between the cells and the external environment
• phospho lipid bi layer
• protein channel

Question 2

nucleus

Answer 2

storage centre of cells DNA (manages cell function)

Question 3

cell wall

Answer 3

• rigid boundary around the plant cell

- provides structure and support

Question 4

cytoplasm

Answer 4

-contains nutrients and surrounds the organelles

Question 5

ribosomes

Answer 5

• makes protein and is located in the cytoplasm and on RER

Question 6

chloroplasts

Answer 6

contains chlorophyll, and i where photosynthesis takes place

Question 7

RER

Answer 7

moves proteins within the cell

Question 8

SER

Answer 8

moves lipids around cell / no ribosomes

Question 9

golgi apparatus

Answer 9

receives protein from RER and distributes to organelles

Question 10

mitochondria

Answer 10

converts food into energy for work
cellular respiration
makes Adesacine Tri Phosphate

Question 11

lysosomes

Answer 11

breaks down food particles

Question 12

cilia and flagella

Answer 12

cell movement

Question 13

vacuoles

Answer 13

used for temporary storage of waste

Question 14

two types of membrane

Answer 14

plasma & non - plasma

Question 15

lipids structure

Answer 15

phosphate = attracted to water ( hydrophilic )
lipid = repels water ( hydrophobic )

Question 16

concentration gradient

Answer 16

high to low = no energy needed

low to high = energy needed

Question 17

osmosis

Answer 17

diffusion of water across the cell membrane

Question 18

endocytosis

exocytosis

Answer 18

endocytosis= the active movement of a substance in a cell
exocytosis= ^ outside the cell

Question 19

active transport

Answer 19

when molecules move against concentration gradient 
requires energy (atp)

Question 20

4 types of tissue

Answer 20

1. epithelial (skin)
2. connective (bone)
3. muscular (cardiac, skeletal)
4. nervous (nerves)

Question 21

epithelial

Answer 21

forms on the outer parts of the skin & lines hollow organs

Question 22

connective

Answer 22

provides support for the body

Question 23

muscular

Answer 23

responds to stimuli contracting and lengthening

1. skeletal 2. cardiac 3. involuntary

Question 24

nervous

Answer 24

made up of neurons

Question 25

BMR

Answer 25

basal metabolic rate

Question 26

catabolic

Answer 26

- bigger pieces are broken down - destructive - releases energy - cell respiration

Question 27

anabolic

Answer 27

- reactions construct complex substances - uses energy - protein synthesis - amino acids

Question 28

glycolysis

Answer 28

- breaks down one molecule of glucose to produce two molecules of pyruvate - anaerobic - yields two molecules of atp

Question 29

enzymes

Answer 29

catabolic reaction | - speed up a chemical reaction

Question 30

lock and key

Answer 30

the lock is the enzyme and the key is the substrate. Only the correctly sized key (substrate) fits into the key hole (active site) of the lock (enzyme). they connect at the active site and when a catabolic reaction takes place, the result is an enzyme and a product.

Question 31

cell respiration

Answer 31

when organisms use oxygen to break down food molecules to get chemical energy for cell functions
