Sexual Reproduction In Plants (biology)

Question 1

Male reproductive part

Answer 1

Stamen

Question 2

Female reproductive part

Answer 2

Carpel

Question 3

Parts in the male reproductive part

Answer 3

Anther

Filament

Question 4

Anther

Answer 4

Contains pollen grains

Question 5

Where are the male gametes produced?

Answer 5

In pollen grains

Question 6

Filament

Answer 6

Stalk that supports the anther

Question 7

What does the female reproductive part consist of?

Answer 7

Stigma
Style
Ovary

Question 8

Stigma

Answer 8

The end bit that the pollen grains attach to

Question 9

Style

Answer 9

The rod like section that supports the stigma

Question 10

Ovary

Answer 10

Contains the female gametes inside ovules

Question 11

Pollination

Answer 11

The transfer of pollen from an anther to a stigma, so that the male gametes can fertilise the female gametes in sexual reproduction

Question 12

Cross-pollination

Answer 12

A type of sexual reproduction where pollen is transferred from the anther of one plant to the stigma of another

Question 13

How are plants adapted for insect pollination?

Answer 13

Brightly coloured petals
Scented flowers and nectaries
Big, sticky pollen grains
Sticky stigma

Question 14

How are plants adapted for wind pollination?

Answer 14

Small, dull petals
No nectaries or strong scents
Lots of pollen grains (they are small and light)
Long filaments that hang outside the flower
Light and feathery stigma

Question 15

Where does the pollen grain land during fertilisation?

Answer 15

On the stigma of the flower

Question 16

How does fertilisation occur?

Answer 16

• pollen grain lands on the stigma
• pollen tube grows out of the pollen grain
• it enters the ovule through the microphyle
• nucleus from male gamete fuses with female nucleus to make a zygote
