Cells

Question 0

what is the function of the cytoplasm?

Answer 0

• jelly like substance in which all the cells organelles are suspended
• hold organelles together
• where most cellular activities occur
• helps to move materials around the cell, dissolves cellular waste

Question 1

what is the function of the cell membrane?

Answer 1

• forms a border around the cell and separates the inside of the cell from the outside environment
• protects the cell from its surroundings
• selectively allows nutrients to enter and leave the cell
• controls the movement of substances in and out of the cell
• attachment surface for extracellular structures

Question 2

what is the function of the nucleus?

Answer 2

• largest organelle in the cell
• coordinates all activities of the cell
• keeps it alive and functioning
• contains DNA (deoxyribonucleic acid)

Question 3

what is the function of the nucleolus?

Answer 3

• to produce and hold RNA
• to produce and assemble subunits which form ribosomes
• plays a part in the manufacture of proteins

Question 4

what is the function of the mitochondria?

Answer 4

• site of cellular respiration (makes energy)

Question 5

what is the function of the golgi body?

Answer 5

• modification, packaging, storage and secretion of cell products
• helps in getting rid of wastes produced by the cell

Question 6

what is the function of lysosomes?

Answer 6

• contain digestive enzymes that break down large molecules

digestive function in the cell

Question 7

what is the function of the smooth e.r?

Answer 7

• communication network between the cytoplasm and the nucleus
• helps with movement of nutrients around the cell
• produces lysosomes

Question 8

what is the function of the rough e.r?

Answer 8

• site of protein synthesis

- produces proteins

Question 9

what is the function of the ribosomes?

Answer 9

• where proteins are made

Question 10

what is the function of the centriole?

Answer 10

• formation and organisation of the spindle fibres during mitosis
• helps in the completion of cytokinesis during cell division

Question 11

what is the function of the cell pore?

Answer 11

• gap in the nuclear membrane allowing substances in and out of the nucleus

Question 12

what is the function of the nuclear membrane?

Answer 12

• separates the nucleus from the rest of the organelles

- double membrane which has nuclear pores to allow certain substances in and out of the nucleus
