Plants

Question 1

Flower

Answer 1

Reproduction

Question 2

Leaf

Answer 2

Photosynthesis and transpiration . Leaves breathe carbon dioxide and breathe out oxygen(gas exchange) . Food storage .

Question 3

Transpiration

Answer 3

Cools the plant when water vapour passes through it .

Stomata are like the pores of leaves .

Question 4

Photosynthesis

Answer 4

Makes food for the plant

Question 5

Gas exchange

Answer 5

Allows the exchange of carbon dioxide and oxygen

Question 6

Stem

Answer 6

The stem allows transport of food , water and minerals around the plant .
Also supports the plant and holds it upright .
Stems store food e.g potato
Gas exchange in lenticles

Question 7

Fruit

Answer 7

Protects seeds

Provides food for seeds

Question 8

Bud

Answer 8

Allows new leaves and flowers to grow . Apical bud at top , lateral buds on the side .

Question 9

Roots

Answer 9

Anchor and support
Take in water and nutrients
Store food e.g carrots and turnips

Question 10

Water

Answer 10

Is absorbed up through the roots , and travels to the leaves and the tips of the plant though the XYLEM

Question 11

Xylem

Answer 11

Water and dissolved solids e.g minerals

Question 12

Phloem

Answer 12

Food from leaves around the plant

F&F

Question 13

Photosynthesis

Answer 13

Is the process where green plants make food using light energy

Question 14

Chlorophyll

Answer 14

Is the green chemical needed for photosynthesis, it is found in the chloroplast of plant cells

Question 15

Carbon dioxide

Answer 15

Enters the stomata (holes on underside of leaf)

Question 16

Photosynthesis word equation

Answer 16

carbon dioxide + water –> glucose + oxygen

Question 17

How are leaves designed for photosynthesis

Answer 17

Leaves are flat and thin so sunlight can get through them

Leaves have tiny holes called STOMATA to allow oxygen out and carbon dioxide in .

Question 18

What do leaves need for photosynthesis

Answer 18

Carbon dioxide comes from the atmosphere
Water comes in through the from the soil
Chlorophyll in their chloroplasts
Sunlight

Question 19

What do the plants do with the glucose when they make it

Answer 19

Like us , plants use glucose for growing and repairing damaged parts
If they don’t use it they store it as starch this is why we can eat plants that store starch such as potatoes and wheat .
