Plants

Question 1

Flower

Answer 1

Is for reproduction, that make seeds, it contains male and female sex organs

Question 2

Leaf

Answer 2

Makes food for the plant, it cools the plant when water vapour passes through it, allows the exchange of carbon dioxide and oxygen, it stores food

Question 3

Fruit

Answer 3

Protects the seeds, provides food for seeds

Question 4

The bud

Answer 4

Allows new leaves and flowers to grow

Question 5

Stem

Answer 5

Allows transport of food water and minerals around the plant, it also supports the plant and holds it upright, stores food

Question 6

Roots

Answer 6

Anchor and support take in water and nutrients stores food eg carrots and turnips

Question 7

Transport in plants

Answer 7

There are vessels in a plant, the xylem and phloem. Minerals from the soil are dissolved in the water and so travel in the xylem also

Question 8

Xylem

Answer 8

Water is absorbed up through the roots and travels to the leaves and the tips of the plant through the xylem

Question 9

Phloem

Answer 9

Food from the leaves travels to the other parts of the plant in the phloem

Question 10

Transpiration

Answer 10

The loss of vapour from the stomata of the leaves

Question 11

Stomata

Answer 11

Little holes on the underside of the leaves

Question 12

Transpiration stream

Answer 12

The flow of water from the roots up through the plant and out the leaves

Question 13

Stimulus

Answer 13

anything that causes a response in an organism

Question 14

Plants respond to stimuli

Answer 14

Of light and gravity

Question 15

Shoot tropism

Answer 15

Shoots/stems are positively phototrophic, negitavly

Question 16

Why is geotropism good

Answer 16

It makes sure plant roots travel down to find water and minerals in soil, having deep roots means the plant is anchored in the soil

Question 17

Why is phototropism good

Answer 17

It makes sure plants get enough light for photosynthesis, so that they can make food

Question 18

Photosynthesis

Answer 18

Where green plants make food using light energy

Question 19

Chlorophyll

Answer 19

A green chemical needed for photosynthesis it is found in chloroplasts in plant cells

Question 20

How are leaves designed for photosynthesis

Answer 20

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 21

Sexual reproduction

Answer 21

The flower is a sexual reproduction organ of the plant, male cells called pollen are made here, female cells called egg cells are made here

Question 22

Sepal

Answer 22

Protects the flower before it blooms

Question 23

Petals

Answer 23

Coloured and scented to attract insects

Question 24

Male parts

Answer 24

Stamen made up of filament and anther

Question 25

Filament

Answer 25

Holds up another

Question 26

Anther

Answer 26

Makes pollen

Question 27

Female parts

Answer 27

Carpel made up of the stigma style and ovary

Question 28

Ovary

Answer 28

Makes the egg or ovule

Question 29

Stigma

Answer 29

Pollen lands and sticks to it

Question 30

Style

Answer 30

Makes a tube for the pollen (male gamete) to travel down to the egg (female gamete)

Question 31

Pollination

Answer 31

The transfer of the pollen from the stamen (anther) of one plant to the carpel(stigma) of another

Question 32

Fertilisation

Answer 32

Fertilisation is the fusion of the male gamete nucleus with the female gamete nucleus to form a zygote
