12 Questions
What is the main difference between self-pollination and cross-pollination in terms of genetic variation?
Self-pollination leads to little genetic variation, whereas cross-pollination promotes more genetic variation.
What are the key features of wind-pollinated flowers?
Pollen grains are small, green, and light; anthers are exposed to the wind; and the stigma is feathery.
How does fertilization occur in plants?
A pollen grain lands on the stigma, forms a pollen tube, and the nucleus of the pollen grain travels down the pollen tube to fuse with the egg cell nucleus.
What are the main methods of seed dispersal mentioned in the text?
Wind, animals, and water are the main methods of seed dispersal.
What are the necessary conditions for germination to occur?
Water, oxygen, and warmth are necessary for germination.
What is the definition of germination?
Germination is when a seed starts to grow.
What is the main difference between asexual and sexual reproduction in terms of genetic uniqueness?
Asexual reproduction produces genetically identical offspring, while sexual reproduction produces genetically unique offspring.
What is the role of the sepal in a flower?
The sepal protects the flower as a bud.
What is the function of the nectary in a flower?
The nectary provides nectar to attract pollinators.
What is the process called when pollen is transferred from the anther to the stigma?
Pollination.
What is the term for the collective name for the female parts of a flower?
Carpel.
What is the role of the style in a flower?
The style folds the stigma to where it can best receive pollen.
Learn about the two types of plant reproduction: asexual reproduction, which involves one parent and produces genetically identical offspring, and sexual reproduction, which involves the fusion of genetic material from two parents and produces genetically unique offspring.
