Organelle Function

Question 1

Centrioles Function

Answer 1

Forms a spindle of protein fibres that move the chromosones during celldivision

Question 2

Plama Membrane Function

Answer 2

A selective permiable barrier that controls the passage pf subtances in and out the cell

Question 3

Nucleus

Answer 3

Chromosones containing DNA that controls the synthesis of protein. Risosomes are fomred in the nucleus

Question 4

Mitocondria

Answer 4

The site of aerobic resbiration and responsible for producing most of the ATP in the cell

Question 5

ER

Answer 5

Forms a system of channels for transporting materials through the cytoplasm. One type has ribosomes ond its surface and is the site of protein synthesis. The other type has no ribosomes and is where steriodies and lipids are synthesised

Question 6

Golgi Body

Answer 6

Recieves protein synthesised on the ER and prepares them for secretion from the cell. This often involes adding carbohydres to the proteins to make them into glycopproteins

Question 7

Lysosomes

Answer 7

Responsible for destroying old organelles that are broken. Phagocytes use lysosomes to disgest engulfed bacteria

Question 8

Chloroplast

Answer 8

Contain photosynthetic pigments which trap light energy for photosynthesis

Question 9

Ribosomes

Answer 9

Protein synthesis. Primary protein sturcute is formed at the ribosomes

Question 10

Vacuole

Answer 10

Contains cellsap and stores solutes such as glucose. Swells due to osmosis.

Question 11

Nuclear Pores

Answer 11

Allows the transport of mRNA and ribosomes in and out of the nucleus

Question 12

Nuclear envelope

Answer 12

Separates the contents of the nucleus from the cytoplasm

Question 13

Nucleolus

Answer 13

Produces rRNA, tRNA and ribosomes
