apomixis is an example of?
2057
Apomixis is an asexual reproduction that occurs without fertilization and not involving meiosis. One example of apomixis is the apomictic parthenogenesis. It its one in which the egg cell is produced through mitosis. It then develops directly into an embryo without the prior fertilization.

Like the pineapple and mulberry, both are multiple fruits composed of numerous ripened ovaries derived from numerous separate flowers. Three examples of multiple fruits: A. Jackfruit (Artocarpus heterophyllus); B. Pineapple (Ananas comosus); and C.

All of the grasses plus bamboo, irises, nutsedge, and palm trees are examples of monocots. Roses, hardwood trees, poison oak, and clovers are members of the dicot group.

(Not all dicots' seed leaves emerge during germination; for example, peas are dicots, but the pea cotyledons remain underground.) Corn is an example of a monocot. Corn seed has one cotyledon and can't readily be split. Familiar monocots include grasses, corn, irises, palms, and lilies.

Asexual reproduction in plants. It is possible for plants to reproduce asexually (ie without fertilisation in flowers). Three methods of plant asexual reproduction are: Bulbs - underground food storage organs with fleshy leaves that store food and can grow and develop into new plants, eg onions and garlic.

In regard to its ploidy, there are three types of cycles; haplontic life cycle, diplontic life cycle, diplobiontic life cycle. These three types of cycles feature alternating haploid and diploid phases (n and 2n). The haploid organism becomes diploid through fertilization, which joins of gametes.

Legumes (pea, beans, lentils, peanuts) daisies, mint, lettuce, tomato and oak are examples of dicots. Grains, (wheat, corn, rice, millet) lilies, daffodils, sugarcane, banana, palm, ginger, onions, bamboo, sugar, cone, palm tree, banana tree, and grass are examples of plants that are monocots.

In botany, apomixis was defined by Hans Winkler as replacement of the normal sexual reproduction by asexual reproduction, without fertilization. ... In flowering plants, the term "apomixis" is commonly used in a restricted sense to mean agamospermy, i.e., clonal reproduction through seeds.

Endosperm is triploid (3n) in most of the angiospermic plant as two polar nuclei fuse with a male gamete and three of them are haploid. But the number varies from 2n to 15n in different species.

Finally, polyploidy in plants is a type of sympatric speciation in which two sympatric species having different chromosome numbers or morphologies form a hybrid, and that hybrid produces offspring with a doubled number of chromosomes (one full genome from each parental species).

In these plants the flowers all have both male and female sexual organs. Roses are an example of a hermaphrodite plant – their flowers all contain both male stamen and female stigma so the likelihood is that the egg will be fertilised by pollen from the same flower.
