Answer 10

provides an important structure framework for cell shape

Question 11

Centrosome

Answer 11

Responsible for the organization and nucleation of microtubules in animal cells

Question 12

Question 15

Central Vacuole

Answer 15

Holds materials and wastes

maintains proper pressure

Question 16

Cilia

Answer 16

Move liquid past the surface of the cell

Question 17

What is the function of the mitochondrion?

Answer 17

To carry out the reactions of cellular respiration

Question 18

What is the formula for cellular respiration?

Answer 18

C6H1206 + 6O2 –> 6CO2 + 6H2O + energy (ATP)

Question 19

What is the appearance of mitochondrion?

Answer 19

Contains two membranes:

smooth outer membranes
-Highly folded inner membrane that provides many locations for proteins that help make most ATP molecules (Cristae)

In the centre of the structure, there is a protein-rich fluid called the matrix.

Question 20

What is the function of Chloroplast?

Answer 20

• carries out the reactions of photosynthesis

- food can also be stored and used as starting material energy source for the reactions of cellular respiration.

Question 21

What is the formula for photosynthesis?

Answer 21

6CO2 + 6H2O –> C6H1206 + 602

-needs light, chlorophyll, and enzymes.

Question 22

What is the appearance of Chloroplast?

Answer 22

contains two membranes:
Outer membrane
Inner membrane

In the centre of the structure, there are stacks of thylakoids that contain pigments such as chlorophyll.

Question 23

Prokaryotic

Answer 23

organism with cells lacking a true nucleus

Question 24

Eukaryotic

Answer 24

Organisms containing nuclei and other types of membrane-bound organelles.

Question 25

Stroma

Answer 25

Ground substance of the chloroplast surrounding the thylakoid membrane
is involved in the photosynthesis.

Question 26

Pili

Answer 26

Hollow, hair-like structure on the surface of prokaryotic cells that allows them to attach to each other or to a surface.

Question 27

Thylakoids

Answer 27

Membrane system consisting of interconnected flattened sacs containing chlorophyll.

Question 28

Capsule

Answer 28

sticky, gelatinous shell around the cell wall of some bacteria; slime layer.

Question 29

Centriole

Answer 29

Short, cylindrical organelle found in animal cells and made up of microtubules.

Question 30

Plasmid

Answer 30

Small self-duplicating loop of DNA in a material cell that is separate from the main chromosome and contains from one to a few genes.

Question 31

Vesicle

Answer 31

small membrane sac for transport or storage of materials within a cell.

Question 32

Nucleus

Answer 32

Organelle with a double membrane that contains the DNA instructions for making proteins.
