B4.7 Transport systems in plants

Question 1

What is the main product of photosynthesis?

Answer 1

Glucose

Question 2

What does the phloem transport?

Answer 2

Transports sugars made by photosynthesis

Question 3

What is translocation?

Answer 3

Question 4

Is the phloem a living tissue?

Answer 4

Question 5

What does the Xylem transport?

Answer 5

Answer 8

For photosynthesis

Question 9

What is the equation for photosynthesis?

Answer 9

Carbon dioxide + water = glucose + oxygen

Question 10
