Question

Define sexual reproduction define two methods of assexual reproduction class 8

Answer 1

Answer:

1. Sexual reproduction is the production of new living organisms by combining genetic information from two individuals of different types (sexes). In most higher organisms, one sex (male) produces a small motile gamete which travels to fuse with a larger stationary gamete produced by the other (female).
2. Asexual reproduction includes fission, budding, fragmentation, and parthenogenesis, while sexual reproduction is achieved through the combination of reproductive cells from two individuals.

Answer 2

Answer:

Step-by-step explanation:

Asexual reproduction is a type of reproduction where fertilization does not take place as only a single parent is involved. Offspring produced is identical to the parent because they are produced as clones. Types of asexual reproduction are as follows: fission, budding and fragmentation.

A. Fission: This type is mainly seen in unicellular prokaryotes. A full-grown organism at a certain stage splits into two identical daughter organisms.

B. Budding: In this type of asexual reproduction, a 'bud' or an outgrowth is formed on the mature adult body and eventually this bud separates and acts as an individual organism.

Sexual reproduction involves two parents and produces offspring that are genetically unique.
