Question

Do all living things reproduce sexually?

Answer 1

Hint: Reproduction is a process by which new organisms are produced. It can be sexually or asexually. Each organism exists due to reproduction only.

Complete answer:
There are two type of reproduction one is sexual and other is asexual.
Sexual reproduction lead to genetic diversity and giving rise to new combination whereas asexual reproduction is energy efficient and offspring’s usually resemble their parents.
Types of asexual reproduction:
1. Budding: mostly occurs in yeast, new buds are formed and later separate as new organisms.
2. Vegetative propagation: reproduction that occurs by parts of plant (stem, shoot, leaves) other than seed.
3. Parthenogenesis: reproduction by unfertilized eggs. Egg develops into an embryo without fertilization. Usually in bees, ants.
4. Binary fission: cells or the organism divide into two and give rise to two daughter cells that are completely identical.
5. Spore formation: organisms form spore and later during favorable conditions these develop to new plants or organisms.
6. Multiple fission
Types of sexual reproduction
It can be internal or external fertilization.
Internal fertilization is when the males release sperm inside the body of the female.
External fertilization is when the male releases sperm on the egg of the female outside the female's body.
Hence organisms can reproduce sexually and asexually both.

Note:
During sexual reproduction fusion of male and female gametes occur where zygote is formed. Whereas no zygote formed in asexual reproduction.
