1 Question: Explain the various methods of asexual reproduction in plants with examples.

Answer: Asexual reproduction methods in plants include vegetative propagation (e.g., runners, rhizomes), budding (e.g., Hydra and yeast), spore formation (e.g., fungi), and binary fission (e.g., bacteria).

2 Question: What is vegetative propagation, and what are its advantages in horticulture?

Answer: Vegetative propagation is a form of asexual reproduction in plants where new plants grow from various plant parts like roots, stems, and leaves. Advantages include the production of genetically identical plants and preservation of desirable traits.

3 Question: Describe the process of pollination and the different types of pollination.

Answer: Pollination is the transfer of pollen from the anther to the stigma. It can be self-pollination (within the same flower) or cross-pollination (between different flowers).

4 Question: Explain double fertilization in angiosperms.

Answer: Double fertilization is a unique feature of angiosperms where two sperm cells fertilize the egg and two polar nuclei. One forms the zygote, while the other forms the triploid endosperm.

5 Question: Describe the development of seeds and fruits in flowering plants.

Answer: After fertilization, ovules develop into seeds, and the ovary becomes the fruit. The fruit protects and aids in the dispersal of seeds.

Human Reproduction:

6 Question: Explain the structure and functions of the male reproductive system.

Answer: The male reproductive system includes the testes (sperm production), epididymis (storage and maturation of sperm), vas deferens (sperm transport), and accessory glands (providing seminal fluid).

7 Question: Discuss the menstrual cycle, ovulation, and hormonal control of the female reproductive system.

Answer: The menstrual cycle involves the release of an egg (ovulation) and is regulated by hormones like FSH and LH. The female reproductive system includes the ovaries, fallopian tubes, uterus, and cervix.

8 Question: How does fertilization occur, and what happens during early embryonic development?

Answer: Fertilization occurs when a sperm cell penetrates the egg, forming a zygote. The zygote undergoes mitotic divisions, forming a blastocyst, which implants in the uterus.

Reproductive Health:

9 Question: List common reproductive health issues ans).d sexually transmitted infections (STI

Answer: Common reproductive health issues include infertility, menstrual disorders, and reproductive cancers. STIs include HIV, gonorrhea, syphilis, and chlamydia.

10 Question: Describe various methods of contraception, their advantages, and disadvantages.
