1What is pollination?
The transfer of pollen from anther to stigma.
2What is fertilisation in plants?
Fusion of male and female nuclei.
3Where are pollen grains produced?
In the anthers.
4Where are ovules found?
In the ovary.
5What is the male part of a flower called?
The stamen.
6What are the parts of a stamen?
Anther and filament.
7What is the female part of a flower called?
The carpel.
8What are the parts of a carpel?
Stigma, style, and ovary.
9What is the function of the stigma?
To receive pollen.
10What is the function of the anther?
To produce pollen grains.
11What is self-pollination?
Pollen transferred to the same plant.
12What is cross-pollination?
Pollen transferred to a different plant of the same species.
13Why is cross-pollination advantageous?
It increases genetic variation.
14What is a pollen tube?
A tube that grows from the pollen grain to the ovule.
15What is the function of the pollen tube?
To transport male nuclei to the ovule.
16What is double fertilisation?
One nucleus forms the zygote and one forms the endosperm.
17What is the zygote?
The fertilised egg cell.
18What is the endosperm?
Food store for the developing embryo.
19What is seed dispersal?
The spreading of seeds away from the parent plant.
20Why is seed dispersal important?
It reduces competition between plants.
21Name a method of seed dispersal.
Wind, water, or animals.
22What is germination?
The growth of a seed into a seedling.
23What conditions are needed for germination?
Water, oxygen, and suitable temperature.
24What is the role of enzymes in germination?
To break down stored food molecules.
25What is the micropyle?
A hole in the seed coat for water uptake.
26What is the testa?
The seed coat.
27What is the cotyledon?
A seed leaf storing food.
28What is vegetative propagation?
Asexual reproduction in plants.
29Name a method of vegetative propagation.
Runners, tubers, or bulbs.
30What is tissue culture?
Growing plants from small tissue samples.
31What is an advantage of tissue culture?
Rapid production of identical plants.
