Reproduction Of Plants Flashcards
What is sexual reproduction in plants?
Sexual reproduction in plants involves the fusion of male and female gametes to form a seed, which then develops into a new plant. This process typically involves flowers.
What are the parts involved in sexual reproduction in flowering plants?
The main components of a flower are stamens, which produce pollen, which contains the ovary. Pollination is the transfer of pollen from the stamen to the pistil, leading to fertilization and seed formation.
How does pollination occur in plants?
Pollination happens through wind, water, and animal pollinators like bees and birds. It’s crucial for fertilization.
Why is genetic diversity important in sexual reproduction?
Genetic diversity from sexual reproduction increases traits in a population, making it more adaptable and resistant to genetic disorders.
What is asexual reproduction in plants?
Asexual reproduction produces new plants without fertilization, typically using vegetative parts and resulting in genetically identical offspring.
What are some common methods of asexual reproduction in plants?
Vegetative propagation uses plant parts (runners, tubers, or bulbs)
while cuttings involve taking a portion of a plant to grow into a new plant. Layering bends a stem to the ground to develop roots, and division splits a plant to grow into new sections.
What are the advantages of asexual reproduction in plants?
Asexual reproduction allows for rapid reproduction and colonization of an area and ensures that the new plants are well-adapted to the local environment as genetic clones of the parent plant.
What are some disadvantages of asexual reproduction?
Limited genetic diversity makes plants more vulnerable to diseases, pests, and environmental changes and reduces their evolutionary potential compared to sexual reproduction.
Can a plant reproduce both sexually and asexually?
Yes
e.g. (Strawberries)
