Plant Reproductive Systems and Processes
What are the two main types of plant reproduction?
Sexual and asexual reproduction.
What are gametes in the context of plant reproduction?
Gametes are the reproductive cells, such as pollen (male) and ovules (female) in plants.
What is the process of transferring pollen from anthers to stigma called?
Pollination.
What is the difference between self-pollination and cross-pollination?
Self-pollination occurs within the same plant, while cross-pollination occurs between different plants.
What is the purpose of flowers in plant reproduction?
Flowers house the reproductive organs of many plants and facilitate pollination and fertilization.
What is asexual reproduction in plants?
It's a form of reproduction that doesn't involve gametes, producing offspring genetically identical to the parent.
Give an example of a plant that reproduces asexually through runners.
Strawberries reproduce asexually using runners.
What is the term for a plant's reproductive organ that produces sperm?
Anther.
What is a seed, in biological terms?
A seed is an embryonic plant enclosed in a protective outer covering.
What is the double fertilization event in angiosperms?
It involves one sperm fertilizing the egg, forming a zygote, and another sperm fusing with two nuclei to form endosperm.
Which part of the flower becomes the fruit?
The ovary develops into the fruit after fertilization.
What is vegetative reproduction?
A form of asexual reproduction where new plants grow from parts such as roots, stems, or leaves.
What is the function of the stigma in plant reproduction?
The stigma captures pollen for fertilization.
Name a plant that reproduces through underground stems called rhizomes.
Ginger reproduces through rhizomes.
What role do pollinators like bees play in plant reproduction?
Pollinators transfer pollen from one flower to another, aiding in cross-pollination.

4. What is the difference between self-pollination and cross-pollination?
Self-pollination occurs within the same plant, while cross-pollination occurs between different plants.
Self-pollination occurs in the morning, while cross-pollination occurs at night.
Self-pollination uses bees, while cross-pollination uses wind.
Self-pollination results in fruit, while cross-pollination results in flowers.
