Differentiate sexual from asexual reproduction in terms of (1) number of individuals involved; (2) similarities of offspring to parents
Reproduction is the ability of a living organism to produce new individual. Also, it is the process of perpetuation of species. Organisms may reproduce sexually or asexually.
There are 2 general ways in which living organisms reproduce: sexually and asexually.
SEXUAL & ASEXUAL REPRODUCTION
Sexual Reproduction is a mode of reproduction that involves 2 parents. Parents reproduce sex cells or gametes. When these gametes from parents unite in the process called fertilization, the fertilized cell or zygote is formed and developed into 2 individual. Human and animals reproduce through sexual reproduction.
Flowering plants also reproduced sexually. The flowers act as reproductive organs that produce gametes. Through the process of pollination, pollen grains land on stigma forming tube that grows down through the pistil and reaches the ovule in the ovary.
Asexual reproduction produce offspring from a single parent
Vegetative propagation- a type of sexual reproduction through which a plant produce its kind by cutting a part of a plant.
(example: potato eye or bud is cut and planted to grow a potato, leaves of kataka taka grow plantlets on leaf margin)
Budding- A new individual grow and separate from the parent and becomes new individual.
(example: yeast, hydra and sponges)
Spore formation- spore case containing the spore are released on a favorable environment and it develops to a new organism.
(example: bread molds)
Regeneration- When organism fragmented, each piece grow into another same kind of organism. The process in which organisms replace or restore their lost or damaged body part is called regeneration.
