KS2 Science Quiz - Plant Reproduction (Questions)

In this KS2 Science quiz we take a look at plant reproduction. This involves the different parts of flowers, pollination, seed dispersal and germination.

All living organisms reproduce. but what exactly is reproduction? Well, its how a new generation comes into being. Flowering plants need to produce seeds in order to be able to make new plants. We often think of flowers as being beautiful to look at, but they actually play an essential role in the reproduction of most plants. They attract insects who pollinate them. They then produce fruits which contain seeds. Dispersal then takes place as the seeds are spread away from the plant. Some of the seeds will then germinate and become plants themselves.

Do you know the names for the different parts of flowers? Or some of the different methods of seed dispersal? See how much you've learned in your science lessons by trying this Plant Reproduction quiz.

1. Pollen grains are contained in which part of a flower?
[ ] The anthers
[ ] The styles
[ ] The petals
[ ] The sepals
2. Which one of these is not a female part of a flower?
[ ] Style
[ ] Stigma
[ ] Ovary
[ ] Stamen
3. Pollen must be transferred to which part of the flower for pollination to occur?
[ ] Stigma
[ ] Petals
[ ] Sepals
[ ] Stem
4. Some flowers are pollinated by insects. What do other types of flowers use to pollinate them?
[ ] Dying
[ ] The wind
[ ] Fertilisation
[ ] Magic
5. How does a flower's scent and bright colour help it to reproduce?
[ ] Non-colourful flowers do not produce pollen
[ ] Scent and colour attracts people
[ ] Scent and colour attracts insects
[ ] All of the above
6. Which of these describes fertilisation?
[ ] A pollen grain joins with an egg in the flower's ovary
[ ] An insect transfers pollen to the stigma
[ ] A flower disperses its seeds
[ ] The wind blows the pollen grains from the anthers
7. After a flower is fertilised, it dies, but its ovary grows into what?

9. Which of these is not a method of seed dispersal?
[ ] Animals eat the fruit, expelling the seeds
[ ] The wind blows the seeds away
[ ] Insects visit the flower
[ ] The seed pod explodes, scattering the seeds
10. What is germination?
[ ] When a flower is pollinated
[ ] When a seed begins to grow

KS2 Science Quiz - Plant Reproduction (Answers)
1. Pollen grains are contained in which part of a flower?
[x] The anthers
[ ] The styles
[ ] The petals
[ ] The sepals
The anther is part of the stamen
2. Which one of these is not a female part of a flower?
[ ] Style
[ ] Stigma
[ ] Ovary
[x] Stamen
The 'men' in 'stamen' is a helpful reminder that the stamen is a male part of the flower. The stigma, style and ovary together form the carpel, which is female
3. Pollen must be transferred to which part of the flower for pollination to occur?
[x] Stigma
[ ] Petals
[ ] Sepals
[ ] Stem
The stigma is the tip of the carpel
4. Some flowers are pollinated by insects. What do other types of flowers use to pollinate them?
[ ] Dying
[x] The wind
[ ] Fertilisation
[ ] Magic
Plants pollinated by the wind usually have less colourful flowers
5. How does a flower's scent and bright colour help it to reproduce?
[ ] Non-colourful flowers do not produce pollen
[ ] Scent and colour attracts people
[x] Scent and colour attracts insects
[ ] All of the above
The scent and the colour advertise the flower to insects. The insects go there to get nectar but carry pollen from flower to flower as they do
6. Which of these describes fertilisation?
[x] A pollen grain joins with an egg in the flower's ovary
[ ] An insect transfers pollen to the stigma
[ ] A flower disperses its seeds
[ ] The wind blows the pollen grains from the anthers
Cells travel from the pollen to the egg and fertilise it
7. After a flower is fertilised, it dies, but its ovary grows into what?
[ ] A new flower
[ ] A new plant
[x] A fruit
[ ] A herb
Fruits contain the seeds which will be able to grow into new plants
8. Seeds cannot stay on the parent plant. What must happen to the seeds in In order for them to grow?
[ ] They must be expelled
[ ] They must be fertilised
[ ] They must be pollinated
[x] They must be dispersed
'Dispersed' means spread over as wide an area as possible
9. Which of these is not a method of seed dispersal?
[ ] Animals eat the fruit, expelling the seeds
[ ] The wind blows the seeds away
[x] Insects visit the flower
[ ] The seed pod explodes, scattering the seeds
Insects visit the flower during pollination, not dispersal
10. What is germination?
[ ] When a flower is pollinated
[x] When a seed begins to grow
[ ] When the seeds leave the parent plant
[ ] When the pollen meets the egg
Seeds need warmth, water and a safe place to germinate
