Biology - Cells and Respiration

Question 1

What can be found in a plant cell but not in an animal cell?

Answer 1

A cell wall
A vacuole
Chloroplasts

Question 2

What is a tissue?

Answer 2

A group of similar cells which come together.

Question 3

What is an organ?

Answer 3

A group of different tissues working together.

Question 4

What is diffusion?

Answer 4

When a substance moves from an area of high concentration to an area of low concentration.

Question 5

What is respiration?

Answer 5

A chemical reaction where energy is released from glucose (sugar). This energy is used for functions to keep you alive such as building proteins and muscle contractions

Question 6

What is the difference between aerobic and anaerobic respiration?

Answer 6

Aerobic: Glucose and oxygen react to produce carbon dioxide and water and this produces energy.
Anaerobic: Respiration without oxygen, produces lactic acid in humans.

Question 7

What is the equation for aerobic respiration?

Answer 7

Glucose + Oxygen -> Carbon Dioxide + Water (+ energy)

Question 8

What is the equation for anaerobic respiration in humans?

Answer 8

Glucose -> Lactic Acid (+ energy)

Question 9

Which sort of respiration is the most efficient?

Answer 9

Aerobic

Question 10

Where in the cell does respiration take place?

Answer 10

Mitochondria

Question 11

What is fermentation?

Answer 11

When anaerobic respiration in yeast produces ethanol - this process can be used to make beer.
