Question 1

four basic functions of eukaryotic cell organelles

Answer 1

1. genetic control of cell (nucleus, ribosomes)
2. manufacture, distribution and breakdown of molecules (ER, GA, vacuoles)
3. energy processing (mitochondria, chloroplasts)
4. structural support, movement and communication between cells (cell surface membrane, cell wall)

Question 2

protoplasm

Answer 2

cell surface membrane, nucleus, cytoplasm

Question 3

organelles in cytoplasm

Answer 3

ER, ribosomes, golgi body, mitochondria, chloropladts, vacuole

Question 4

nucleus function

Answer 4

contains chromosomes made up of DNA which carries hereditary information

Question 5

RER function

Answer 5

physically modify proteins made by ribosomes

Question 6

ribosome function

Answer 6

protein synthesis (synthesis of polypeptides from amino acids)

Question 7

SER function

Answer 7

1) synthesise substances like fats and steroids
2) detoxification of drugs

Question 8

golgi apparatus/golgi body functions

Answer 8

1) chemically modify substances from the ER
2) stores and packages the substances in vesicles for secretion out of the cell or to other organelles in the cell

Question 9

mitochondrion function

Answer 9

site of aerobic respiration to produce energy in form of ATP for cellular activities

Question 10

chloroplasts function

Answer 10

thylakoid membrane contains chlorophyll which is required for photosynthesis to occur

Question 11

vacuole function

Answer 11

stores substances within the cell (plant cell: disposal of waste materials)

Question 12

differentiation

Answer 12

process by which a cell becomes specialised for a specific function
