Cell organelle functions

Question 1

Cell wall function.

Answer 1

Composed of cellulose, and provides support for the cell.

Question 2

Cytoplasm

Answer 2

• Jelly like fluid.
• Is the site of many cellular reactions.
• Acts as a median for transport inside cell.

Question 3

Large central vacuole

Answer 3

serve a variety of secretory, excretory, and storage functions.

Question 4

Nucleus

Answer 4

regulates cell activity. And contains cell’s genetic material.

Question 5

Chloroplast

Answer 5

Absorbs light energy to make glucose. Contains chlorophyll.

Question 6

Golgi body function

Answer 6

to modify sort and package proteins from the ER for storage and transport within and out of the cell.

Question 7

Ribosomes

Answer 7

site of protein synthesis.

Question 8

Cell membrane

Answer 8

• Thin flexible layer.
• Separates intracellular environment from extracellular environment.
• Regulates what enters and exits cell.

Question 9

Vacuole

Answer 9

• Serve a variety of secretory, excretory and storage functions.

Question 10

Lysosome

Answer 10

Contain digestive enzymes to digest old cell organelles and parts of organelles.

Question 11

Nucleolus

Answer 11

non-membrane bound structure inside nucleus. Function is to transcribe DNA into RNA and assemble it within the cell.

Question 12

Endoplasmic reticulum (ER)

Answer 12

creates network of membranes (plumbing) throughout the cell. ER can be smooth (no ribosomes) or rough (ribosomes present)

Question 13

Mitochondria

Answer 13

site where aerobic respiration is completed.

(have two membranes: outer smooth membrane and inner wrinkled membrane; inner folds of inner membrane called cristae.)
