Flowers and Pollination

Question 1

Pollination

Answer 1

When a males gamete (Pollen Grain) sticks onto a Female Gamete (Stigma) the Plant that has the female gamete will

Question 2

Petals

Answer 2

Are very bright, sweet-smelling and colourful. This to to attract other insects such as bees. These insects will hopefully pollinate the plant.

Question 3

Nectar

Answer 3

A sweet sugary liquid,which bees use to make honey.

Question 4

Insect Pollinated Plants

Answer 4

These types of plants will mainly be pollinated by insects. They will contain lots of nectar and brightly coloured petals.

Question 5

Wind Pollinated Plants

Answer 5

These plants are pollinated by Pollen Grains being blown in by the wind. These plants will contain little/no nectar and will have small, dull petals, however it will produce large amounts of Pollen.

Question 6

Stamen

Answer 6

Plant Male Reproductive Part.

Question 7

Carpel

Answer 7

Plant Female Reproductive Part

Question 8

Anther

Answer 8

Produces Pollen

Question 9

Filament

Answer 9

Holds up the Anther.

Question 10

Stigma

Answer 10

‘Catches’ Pollen Grains. Also, it has to be very sticky to do so.

Question 11

Style

Answer 11

Holds up the stigma. When a Pollen Grain has been ‘Caught’ by the stigma, a Pollen Tube will grow down it in order of the nucleus of it to reach the ovary

Question 12

Ovary

Answer 12

Contains Ovules

Question 13

Ovules

Answer 13

Female Gamete (Egg)

Question 14

What happens to a fertilised Ovule?

Answer 14

When a Pollen Grain’s Nucleus Fertilises an Ovule, it will make a seed.

Question 15

Sepals

Answer 15

Special leaves that protect unopened buds.

Question 16

Leaves

Answer 16

Absorbs sunlight and nutrients from it and the air.

Question 17

What’s inside of a seed?

Answer 17

Food Store, Seed Coat and an Embryo.

Question 18

Seed Coat

Answer 18

A tough, protective layer of the seed acting as an outer covering to protect it underground.

Question 19

Food Store

Answer 19

Stores Starch and food until the plant can make it’s own food.

Question 20

Embryo

Answer 20

The root and shoot of the plant.

Question 21

Conditions needed for Gemination.

Answer 21

Water, Oxygen and Warmth

Question 22

Water

Answer 22

Allows the seed to swell up and helps the embryo to start to grow.

Question 23

Oxygen

Answer 23

Used for respiration, transferring energy for the seed to germinate.

Question 24

Warmth

Answer 24

Speeds up the reactions of the plant, speeding up it’s growth.

Question 25

Methods of Seed Dispersal

Answer 25

Wind, Animals, Water and Explosive Seed Dispersal.

Question 26

Wind Dispersal

Answer 26

Useful for dispersing seeds and fruits. It does this by blowing the seeds in the air

Question 27

Animal Dispersal

Answer 27

Animals either eat then fruit and the seed cone out in it’s waste or a fruit will have ‘hooks’ and ‘hook’ onto the animal.

Question 28

Water Disperal

Answer 28

Seeds will float in the water until it dries out and will hopefully find themselves in a different location.

Question 29

Explosive Dispersal

Answer 29
