In angiosperms, apomixis produces an embryo through asexual reproduction within a seed, bypassing the usual combination of meiosis and fusion of gametes. It can preserve a maternal genetic combination across generations. It differs from vegetative reproduction, which propagates an individual through structures such as shoots or rhizomes rather than through seeds.

Producing a clonal seed requires coordinating more than one developmental event: retaining the maternal chromosome complement and initiating an embryo without ordinary fertilization are separate requirements. Rice research combining altered meiosis with redirected embryogenic gene activity demonstrated clonal propagation through seeds.^[ref] In some forms of apomixis, fertilization is still needed to produce supporting endosperm, so an asexual embryo does not imply that every component of the seed develops without fertilization.

A plant cutting is a detached piece of a plant, such as part of a plant stem, leaf or root system, used to produce another plant by vegetative reproduction. A stem cutting must maintain a living shoot while forming new adventitious roots. Because this bypasses meiosis and fertilization, it can preserve the parental genotype, apart from mutations and pre-existing variation within the parent.

A practical example is a soft young shoot cut below a node, with lower leaves removed and its base placed in a moist, aerated medium. High humidity reduces water loss before the new root system can supply it; aeration avoids treating a rootless cutting as if it were an established waterlogged plant. The balance illustrates a physiological bottleneck: living leaves need water immediately, whereas a functional root system takes time to develop.^[ref]

Plant reproduction produces new plant individuals through sexual reproduction or asexual reproduction. In land plants, alternation of generations connects a gametophyte that makes gametes to a sporophyte that makes spores. A seed is a developing plant embryo with protective and nutritive structures, rather than another name for a spore.

A rhizome can extend and establish new shoots through vegetative reproduction, while pollination can initiate the sequence leading to fertilization and seed production in a flowering plant. These routes differ in how parental genetic variation is transmitted and combined.

Vegetative reproduction is asexual reproduction through vegetative plant organs, rather than through fusion of gametes. A rhizome can extend below ground and produce a new shoot; a plant cutting can form a root system and become independently established. A piece becoming larger is not sufficient: the process must produce a new potential individual.

The offspring usually preserves the parent's genetic combination because ordinary meiosis and fertilization are bypassed. This makes vegetative reproduction useful for propagating a selected plant, but does not guarantee complete identity indefinitely: mutations can arise during mitosis. Apomixis supplies a useful comparison, because it can preserve a maternal genetic combination through a seed rather than through vegetative plant organs.
