B8 - Photosythesis

Question 1

What is Aerobic respiration

Answer 1

An exothermic reaction in which glucose is broken down using oxygen to produce carbon dioxide, water and energy

Question 2

What is anaerobic respiration

Answer 2

An exothermic reaction in which glucose is broken down without oxygen to produce lactic acid and energy

Question 3

What is photosythesis

Answer 3

The process where plants make food using carbon dioxide, water and light
Endothermic reaction because it absorbs light from the surrondings

Question 4

What is the equation for photosythesis

Answer 4

water + carbon dioxide = glucose + oxygen

Question 5

How is glucose used

Answer 5

Converted into cellulose for cells walls
Converted into starch to store the glucose
Converted into nitrates and proteins for growth
Used for respiration

Question 6

Limiting factors of photosythesis

Answer 6

Light intensity
Temperature
CO2 concentration
Water
Pollution

Question 7

How do you calculate light intensity

Answer 7

Inverse square law

Question 8

What is the equation for inverse square law

Answer 8

Light intensity = 1 / distance squared
