Types of Asexual Reproduction. Various types of asexual reproduction mechanisms can be identified like fission, budding, vegetative propagation, sporogenesis, fragmentation, and agamogenesis. Fission Asexual reproduction: Asexual reproduction is by multilateral budding on a narrow base. Cells are ovoid, ellipsoidal, cylindrical to elongate. Pseudohyphae may be formed, but true hyphae are not produced. Sexual reproduction: Conjugation may or may not precede ascus formation.

18 Oct 2001 Why are most organisms sexual?
Budded cells are spherical, ellipsoidal, or often elongate. True hyphae and pseudohyphae are formed; true hyphae have septa with a single central micropore. Asexual reproduction is a feature of lower animals and occurs in all groups of plants, including ANGIOSPERMS, usually in addition to sexual reproduction. Perhaps the fixed location of many plants makes this type of reproduction particularly suitable.

This progeny produced is totally identical to the parent in its genetic makeup. There are organisms that reproduce asexually like bacteria, multicellular organisms like fungi and even plants. Reproduction is known as biological process by which an offspring (or several individual offspring) is brought forth by its producers known as “parents.” There are two types of reproduction: sexual and asexual. Sexual reproduction is the primary method we know in procreation. Asexual reproduction produces individuals that are genetically identical to the parent plant. Roots such as corms, stem tubers, rhizomes, and stolon undergo vegetative reproduction. Some plants can produce seeds without fertilization via apomixis where the ovule or ovary gives rise to new seeds.
