Plants

Question 1

Flower

Answer 1

Reproduction

Question 2

Leaf

Answer 2

Photosynthesis

Transpiration

Gas exchange

Food storage

Question 3

Photosynthesis

Answer 3

Makes food for the plant

Is the process where green plants make food using light energy

The for new leaves and flowers to grow

Apical bud at top, lateral buds on the side

Question 4

Transpiration

Answer 4

Cools the plant when water vapour passes through it

STOMATA = are little holes on the underside of the leaves

Question 5

Gas exchange

Answer 5

Allows the exchange of carbon dioxide and oxygen

Question 6

Food storage

Answer 6

Leaf stores food (e.g. Lettuce)

Question 7

Stem

Answer 7

The stem allows the TRANSPORT of food water and minerals around the plant

It also SUPPORTS the plant and holds it upright

Stems STORE food (e.g. potato)

Gas exchange in LENTICEL

Question 8

Fruit

Answer 8

Protects seeds

Provides food for seeds

Question 9

The bud

Answer 9

The for new leaves and flowers to grow

Apical bud at top, lateral buds on the side

Question 10

Roots

Answer 10

ANCHOR and support

TAKE IN water and nutrients

STORE food (e.g. carrots and turnips)

Question 11

Transport in plants

Answer 11

WATER is absorbed up through roots and travels to the leaves and the tips of the plant through the XYLEM

Phloem = food from leaves around the plant

Food = PHLOEM

Xylem = water and dissolved solids (e.g. minerals)

Water = XYLEM

Question 12

Chlorophyll

Answer 12

Is the green chemical needed for PHOTOSYNTHESIS, it is found in the chloroplasts of plant cells

Question 13

Carbon dioxide

Answer 13

Enters the stomata (holes on the underside of leaf)

Question 14

Photosynthesis word equation

Answer 14

Carbon dioxide + Water -> Glucose + Oxygen

Question 15

How are leaves designed for photosynthesis

Answer 15

• 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 16

What do leaves need to photosynthesis

Answer 16

• carbon dioxide comes from the atmosphere
• water comes in through the roots from the soil
• chlorophyll in their chloroplasts
• sunlight

Question 17

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

Answer 17

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
