Parts Of A Cell

Question 1

Cell membrane

Answer 1

A selectively permeable lipid membrane that controls which substances can enter and leave the cell. Also allows cells to make contact with one another and provides receptor sites for cell specific chemicals such as hormones.

Question 2

Mitochondria

Answer 2

The site of the aerobic phase of cellular respiration and the production of ATP ( energy)

Question 3

Golgi body

Answer 3

Responsible for the secretion of cell products such as lipids and proteins, forms lysosomes.

Question 4

Lysosomes

Answer 4

A membrane bond structure that contains powerful digestive enzymes. These enzymes can be secreted or used to destroy foreign indigested materials or redundant cell structures.can cause the cell to self destruct if damaged.

Question 5

Ribosomes

Answer 5

Made up of ribosomal RNA and is the site of protein synthesis

Question 6

Rough endoplasmic reticulum

Answer 6

Line with ribosomes and transports proteins within the cell

Question 7

Smooth endoplasmic reticulum

Answer 7

Involved in the manufacture of lipids

Question 8

Nucleus

Answer 8

Contains chromosomes whose genes determine the actives of the cell

Question 9

Nucleolus

Answer 9

A non membrane bound structure in the nucleus that stores and
Manufactures ribosomal RNA

Question 10

Centrioles

Answer 10

Involved in the formation of spindles during nuclear division

Question 11

Cilia

Answer 11

Hair linked projections of a cell, they beat rhythmically to move through the whole cell or move material across the cells surface

Question 12

Flagella

Answer 12

Long hair or projection from the cell, often has the function of moving the cell. (Tail)

Question 13

Microvilli

Answer 13

Microscopic projections from the membrane of the cells lining the small intestine; increase surface area for absorption
