Anisogamy is the type of sexual reproduction in which the fusion of two gametes which are morphologically or structurally similar but functionally different. It is found in Chlamydomonas braunii .

Bulbil is the modification of whole buds into swollen structures due to storage of food materials are called bulbils. It helps in vegetative reproduction. It is a swollen, leafy adventitious bud having starch. Example: Garlic bulbil.

Gemma is a leafy cup like structure attached to the thallus of the bryophyte. Example: Marchantia. It helps in vegetative propagation. It involves the splitting off of a single cell, a mass of cells or a bud from the top surface of the thallus of the parent.

Sexual and asexual reproduction are two mechanisms that produce offsprings of the living organisms. The fusion of two gametes which are structurally, functionally and developmentally different is called oogamy. In this process of reproduction, the female gamete is significantly larger than the male gamete and is non-motile. Example: Chlamydomonas coccifera.

Zygospore is a diploid reproductive stage in the life cycle of many fungi and protists. It is created by the nuclear fusion of haploid cells. In fungi, it is called chlamydospores and is formed after the fusion of hyphae of different mating types. It is the thick walled diploid spore formed by the fusion of two isogametes. Example: Spirogyra, Mucor.
