Cell Anatomy

Question 1

Plasma Membrane

Answer 1

made up of phospholipid bilayer, communicates with other cells, controls transport of molecules into and out of a cell

Question 2

Cytoplasm

Answer 2

site of all intracellular activities excluding nucleus, cellular soup

Question 3

Cytoskeleton

Answer 3

shapes, supports and moves cell organelles

Question 4

Centrosome

Answer 4

grows mitotic spindle for mitosis and microtubules

Question 5

Cilla and flagella

Answer 5

Cilla moves fluid over a cell surface, flagella moves entire cell

Question 6

Ribosome

Answer 6

synthesises proteins, made up of two subunits containing ribosomal RNA and proteins.

Question 7

Rough Endoplasmic Reticulum

Answer 7

synthesises glycoproteins and phosphoproteins using ribosomes

Question 8

Smooth Endoplasmic Reticulum

Answer 8

synthesises fatty acids and steroids. Specialised organ function (liver=detoxification, muscle=calcium storage, kidneys=release of glucose)

Question 9

Golgi Complex

Answer 9

Modifies, sorts, repackages and transports proteins from ER through secretory and transport vesicles.

Question 10

Lysosome

Answer 10

Disposes and recycles cellular waste.

Question 11

Peroxisome

Answer 11

Plays a role of detoxification in liver.

Question 12

Mitochondrion

Answer 12

POWERHOUSE OF THE CELL.
site of aerobic cellular respiration reactions that produce most of cell’s ATP. Contain own DNA and have close communication with nucleus.

Question 13

Nucleus

Answer 13

Determines, shape, function and cellular homeostasis. Contains 23 pairs of chromosomes as chromatin. Nucleolus makes RNA. Nuclear pores control movement of substances between nucleus and cytoplasm.
