1

What is the word equation for photosynthesis?

Carbon dioxide + water- light- oxygen + glucose + water

2

How is the lead adapted to increase photosynthesis?

•large surface area- to absorb more light
•thin- shorter distance for gas to diffuse in and out
•chlorophyll- make leaf green and used in photosynthesis
•network of veins to support leaf and transport water and carbohydrase
•stomata- for gas to diffuse in and out

3

What are nitrates used for?

Healthy growth

4

What is a nitrate deficiency?

Poor growth and yellow leaves

5

What are phosphates used for?

Healthy roots

6

What is a phosphate deficiency?

Poor root growth and purple leaves

7

What is potassium used for?

Healthy leaves and flowers

8

What is a potassium deficiency?

Yellow leaves and dead patches

9

What is magnesium used for?

Making chlorophyll

10

What is a magnesium deficiency?

Yellow leaves

11

Describe the process of photosynthesis

Some species of bacteria use a range of chemical reactions to create glucose. No word equation but:
• reactant=co2
• source of energy=chemicals
•product=glucose

It happens when light can't be used to create energy

12

What is the word equation of aerobic respiration?

Glucose + oxygen = carbon dioxide + water + energy

13

Where does aerobic respiration occur?

In the mitochondria

14

What is the word equation for anerobic respiration?

Glucose = lactic acid
