Asexual & Sexual Reproduction
2 parents
What part of the flower produces pollen?
Anther
What is pollination?
Transfer of pollen from anther to stigma.
What develops into a seed?
The fertilised ovule.
Name one method of asexual reproduction in plants.
Cutting, runners, tubers, bulbs, grafting.
What is the female part of the flower called?
The pistil/carpel.
Name one pollinating agent.
Wind, insects, birds, bats, water.
What develops into the fruit?
The ovary.
Offspring from sexual reproduction are genetically...
different
What is the stigma’s role?
To catch pollen.
What happens during fertilisation?
Pollen nucleus fuses with ovule nucleus.
Do all flowers contain male & female parts?
NO
State one advantage of asexual reproduction.
Fast, many offspring, no mate needed.
Name the part located at the base of the pistil that holds ovules.
Ovary.
What structure grows from the pollen grain after it lands on the stigma?
Pollen tube.
What is seed dispersal?
Spreading seeds away from parent plant.
Why does sexual reproduction increase variation?
Offspring receive a mix of genes from both parents during fertilisation.
What is the difference between a petal and a sepal?
Petals attract pollinators; sepals protect the bud.
Why do wind-pollinated plants produce so much pollen?
Low chance of pollen reaching another flower — so more increases success.
Why is seed dispersal important?
Reduces competition and spreads species to new areas.
