Sexual Reproduction in Flowering Plants
1. What is sexual reproduction in plants?
Answer:
Sexual reproduction in plants involves the transfer of pollen, containing male gametes, to the stigma of the flower. This leads to fertilization within the ovary, forming seeds. Seeds germinate into new plant.
2. What are the male and female reproductive structures in a flower?
Answer:
The male reproductive structure is the stamen, which consists of the anther (producing pollen) and filament. The female reproductive structure is the pistil or carpel, comprising the stigma (pollen receptive), style, and ovary.
3. How does pollination contribute to sexual reproduction?
Answer:
Pollination is the transfer of pollen from the anther to the stigma. It facilitates the introduction of male gametes to the female reproductive parts, initiating the fertilization process.
4. What happens during fertilization in plants?
Answer:
Fertilization in plants is a process in which the male gamete (germ cell) fuses with the female gametes( egg cells) within the ovule, forming a zygote. The zygote develops into embryo within the seed, that give rise to a new plant.
5. What is double fertilization in plants?
Answer:
Only one sperm cell fuses with the egg cell, forming a zygote. This step is known as fertilization. Another sperm cells combines with two other cells, forming endosperm, a nutritive tissue. This process is known as double fertilization.
Sexual Reproduction in Flowering Plants – Class 10 Notes
Sexual reproduction in plants involves the transfer of pollen, containing male gametes, to the stigma of the flower. This leads to fertilization within the ovary, forming seeds. Ovary may develop into fruit for seed protection and dispersal. Seeds spread through wind, water, or animals, and under favorable conditions, germinate to give rise to new plants, completing the reproductive cycle.
