Some useful words

Stamen

Style

Stigma

Sepal

Petal

Ovary

Pollen

Reproduction

Germination

Pollination

Fertilisation

Dispersal

the pollen producing part of the flower

where the pollen tubes grow

a sticky section of the flower where the pollen lands

the outermost section of the flower which is usually green and smaller than the petals

usually the brightly coloured parts of the flower used to attract the insects

this protects the ovule and once fertilisation has taken place it will become the fruit.

minute grains, usually yellow in color

organisms generate new individuals of the same kind

when a seed starts to grow

transfer of pollen from the stamen to a stigma

the combining of cells, leading to reproduction

when the seed leaves the flower

Unit 5B: Life Cycles: Vocabulary

unit 5b flowering plants reproduce
Unit 5B: Flowering Plants Reproduce

Flowering Plants Reproduce

Where did the fruits grow from?

What will happen to the fruits?

Why are they important to the plant?

Unit 5B: Flowering Plants Reproduce: L.O. 1: N.C.

unit 5b seed dispersal
Unit 5B: Seed Dispersal

Seed Dispersal

Why do the seeds needs to be dispersed?

How do you think each of the seeds above are dispersed?

Unit 5B: Seed Dispersal: L.O. 2, 3, 4: N.C.

unit 5b germination
Unit 5B: Germination

Germination

What do plants need to grow?

What do you think seeds need to germinate?

Make a list of the factors that you think may affect the germination of cress seeds.

Select one to investigate. Which one have you chosen?

What will you measure and record? How long will you allow for the investigation?

How will you keep it a fair test?

How will you record your results?

WATER

LIGHT

WARMTH

Unit 5B: Germination: L.O. 5, 6, 7, 8, 9, 10: N.C.

…cont

Once you have all the results from your investigation make a conclusion from your results. What do they show?

You will need to confer with other groups to see what their findings were.

Do seeds need warmth to germinate?

Do seeds need water to germinate?

Do seeds need light to germinate?

Are the results as you would have expected them?

Unit 5B: Germination: L.O. 5, 6, 7, 8, 9, 10: N.C.

Germination

Do seeds need light to germinate?

Put equal numbers of cress seeds in 2 dishes on cotton wool.

Water each dish with the same amount of liquid.

Place one of the dishes in a dark room and one near the window.

It is important that they are both the same temperatures to make this a fair test.

Water the 2 dishes every 2 days and check if any of the seeds have germinated

Do seeds need light to germinate?
