Worksheet Overview

QUESTION 1 of 10

Flowering plants use a lot of energy producing flowers which are part of the plant's reproductive cycle. Flowers contain the male and female parts needed for sexual reproduction.

 

The male parts of the flower are the stamen. The filament holds the anther, which produces pollen.

 

The female part of the flower is the pistil or sometimes called carpel. It is made up of the stigma which is 'sticky' to catch the pollen grains, the style, a tube leading to the ovary, which contains the female cells.

Pollination occurs when pollen from the anther of one plant is carried to the stigma of another.

When the pollen joins with the female egg cell, fertilisation has taken place. After this, the petals wither and the seeds grow in the ovary.

The stamen is made up of which TWO of these?

sepal

anther

stalk

petal

filament

What is the scientific name for the male sex cells of a plant?

eggs

pollen

anther

nectar

Pollen from one plant is carried to the stigma of another in which two of these ways?

by the wind

by post

by honeybees

by earthworms

Flowering plants have evolved ways of attracting pollinating insects to their flowers. Can you spot THREE of them from this list?

by producing nectar

by making a noise

by making fruit

by producing a scent

by having colourful petals

Pollen carried in the wind, for example: grass and tree pollen, can make noses run and eyes stream! What do we call this irritation?

The female part of the flower (the carpel) is made up of which THREE parts? 

stigma

style

sepal

ovary

petal

Which statement best describes plant FERTILISATION?

seeds are produced in the ovary

pollen is received by the stigma

joining of the male cell with the female cell

Following fertilisation, what do the female cells develop into in the ovary? 

Here is a list of science words which we use to describe a flowering plant life cycle. Can you re-arrange them in the correct order, starting with the seed? 

seed

flower formation 

fertilisation

germination

seed production

growth

  • Question 1

The stamen is made up of which TWO of these?

CORRECT ANSWER
anther
filament
  • Question 2

What is the scientific name for the male sex cells of a plant?

CORRECT ANSWER
pollen
EDDIE SAYS
Nectar is a sweet liquid produced by the plant to attract pollinating insects.
  • Question 3

Pollen from one plant is carried to the stigma of another in which two of these ways?

CORRECT ANSWER
by the wind
by honeybees
EDDIE SAYS
Without honeybees carrying pollen, we wouldn't have a good fruit harvest!
  • Question 4

Flowering plants have evolved ways of attracting pollinating insects to their flowers. Can you spot THREE of them from this list?

CORRECT ANSWER
by producing nectar
by producing a scent
by having colourful petals
EDDIE SAYS
Plants which attract night-flying insects use scent which is easy to detect in the dark! eg honey suckle
  • Question 5

Pollen carried in the wind, for example: grass and tree pollen, can make noses run and eyes stream! What do we call this irritation?

CORRECT ANSWER
hayfever
  • Question 6

The female part of the flower (the carpel) is made up of which THREE parts? 

CORRECT ANSWER
stigma
style
ovary
  • Question 7

Which statement best describes plant FERTILISATION?

CORRECT ANSWER
joining of the male cell with the female cell
EDDIE SAYS
Fertilisation occurs when the male cells, the pollen, fuses with the female cell, the egg.
  • Question 8

Following fertilisation, what do the female cells develop into in the ovary? 

CORRECT ANSWER
seeds
  • Question 9

Here is a list of science words which we use to describe a flowering plant life cycle. Can you re-arrange them in the correct order, starting with the seed?
