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.

Pollen grains are contained in which part of a flower?

[ ]	The anthers
[ ]	The styles
[ ]	The petals
[ ]	The sepals

Which one of these is not a female part of a flower?

[ ]	Style
[ ]	Stigma
[ ]	Ovary
[ ]	Stamen

Pollen must be transferred to which part of the flower for pollination to occur?

[ ]	Stigma
[ ]	Petals
[ ]	Sepals
[ ]	Stem

Some flowers are pollinated by insects. What do other types of flowers use to pollinate them?

[ ]	Dying
[ ]	The wind
[ ]	Fertilisation
[ ]	Magic

How does a flower's scent and bright color help it to reproduce?

[ ]	Non-colourful flowers do not produce pollen
[ ]	Scent and color attracts people
[ ]	Scent and color attracts insects
[ ]	All of the above

Which of these describes fertilization?

[ ]	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

After a flower is fertilized, it dies, but its ovary grows into what?

[ ]	A new flower
[ ]	A new plant
[ ]	A fruit
[ ]	A herb

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 fertilized
[ ]	They must be pollinated
[ ]	They must be dispersed

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
[ ]	When the seeds leave the parent plant
[ ]	When the pollen meets the egg

Science: Elementary School: Grades 3, 4 and 5 Quiz - Plant Reproduction (Answers)

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

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

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

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 colorful flowers

How does a flower's scent and bright color help it to reproduce?

[ ]	Non-colourful flowers do not produce pollen
[ ]	Scent and color attracts people
[x]	Scent and color attracts insects
[ ]	All of the above

The scent and the color advertise the flower to insects. The insects go there to get nectar but carry pollen from flower to flower as they do

Which of these describes fertilization?

[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 fertilize it

After a flower is fertilized, 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

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 fertilized
[ ]	They must be pollinated
[x]	They must be dispersed

'Dispersed' means spread over as wide an area as possible

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
