Plant Organ System B2

Question 1

Photosynthesis word and symbol equation

Answer 1

Carbon dioxide + water -> glucose +oxygen
6CO2 + 6H2O → C6H12O6 + 6O2

Question 2

How is a leaf adapted to photosynthesise?

Answer 2

Lots of chloroplast. Stomata to allow gas exchange. Spaces between cells to allow,movement of gas

Question 3

Aerobic respiration word and symbol equation

Answer 3

C6 H12 O6 + 6O2 → 6CO2 + 6H2O
glucose + oxygen → carbon dioxide + water

Question 4

Answer 4

Made up of dead cells Thick cellulose wall, strengthened with a lignin wall. Made up of fibres. Function: transfer water and minerals up the plant. hollow tube.

Question 5

Phloem properties and function

Answer 5

Made up of living cells. Permeable cell walls. Thin cell wall. Carries food and nutrients round the plant . Cell wall made of cellulose.

Question 6

What is transpiration?

Answer 6

the evaporation and movement of water away from the plant’s leaves from the inside of the plant

Question 7

How does water get into a plant?

Answer 7

1, absorbed from soil through root hairs via osmosis
2. Transported up the stem in the xylem to leaves (transpiration)
