2. nucleus
3. mitochondria
4. Golgi apparatus and Golgi vesicles
5. lysosomes

7. rough endoplasmic reticulum
8. smooth endoplasmic reticulum
9. cell wall (in plants, algae and fungi)
10. cell vacuole (in plants).
    11.chloroplasts

Question 2

Answer 2

1. cell-surface membrane
2. nucleus
3. mitochondria
4. Golgi apparatus
5. Golgi vesicles
6. lysosomes
7. ribosomes(80s)
8. rough endoplasmic reticulum

Answer 3

1. cell-surface membrane
2. nucleus
3. mitochondria
4. Golgi apparatus
5. Golgi vesicles
6. lysosomes
7. ribosomes (80s)
8. rough endoplasmic reticulum
9. smooth endoplasmic reticulum
10. cell wall (in plants, algae and fungi)
11. cell vacuole (in plants).
    12.chloroplasts

Question 4

what does cell surface plasma membrane do?

Answer 4

.regulates movement of substances into and out of the cell
. responds to hormones using receptors molecules

Question 5

what is the function of nucleus

Answer 5

.controls cells activities, by controlling transcription of DNA
. DNA contains instructions to make proteins.
. nuclear pores allow substances e.g RNA to move into nucleolus
.nucleolus makes ribosomes

Question 6

function of mitochondria

Answer 6

.site of aerobic respiration
.produces ATP
.are found in active cells

Question 7

function of chloroplast

Answer 7

.plants
.site of photosynthesis
either in grana or stroma

Question 8

Golgi apparatus function

Answer 8

.process and packages new lipids and proteins
.makes lysosomes

Question 9

Golgi vesicles function

Answer 9

. produced by Golgi apparatus,
.stores lipids and proteins produced by Golgi apparatus
.AND transports them out of the cell

Question 10

function of lysosomes

Answer 10

. contains digestive enzymes called lysosomes
.digests invading cells and break worn out components in cell

Question 11

function of ribosomes

Answer 11

. ribosomes are 80s in both animal cells in plant cells
.where proteins are made

Question 12

rough endoplasmic reticulum function?

Answer 12

.plants and animals
.folds and processes proteins made by ribosomes

Question 13

smooth endoplasmic reticulum

Answer 13

.plants and animal
synthesises and processes lipids lipids lipids

Question 14

cell wall function

Answer 14

.plants
.supports and prevents cell from changing shape

Question 15

cell vacuole function

Answer 15

.Plants
.maintains pressure inside cell and keeps it rigid.
stops plants wilting.
involved in separating unwanted chemicals inside cells

Question 16

describe algal cells

Answer 16

.similar to plant cells include cell wall and chloroplasts

Question 17

describe fungal cells

Answer 17

.similar to plant cells
.BUT!!!!
. THEIR CELL WALLS ARE MADE FROM CHITIN NOT CELLULOSE
, NO CHOLOPLASTS !, they don’t photosynthesise what kind of fungus cell is green bruh
