Explain plant reproduction

Answer 1

In some plants, water or wind help bring the sperm to the egg. Animals, like insects, bring the egg and the sperm together in other plants.

In some animals, meiosis occurs and there are 5 cycles that take place. Fertilization plays a very important role in sexual reproduction, for both plants andanimals.

Answer 2

Plants can be reproduced either sexually or asexually.

Sexual reproductionrefers to the swapping of genetic information between two parent plants in order to create a hybrid plant with a combination of genetically inherited "traits" from either or both of the parent plants.

In Angiosperms the process occurs in the flowers:

This normally occurs by transferring the male (haploid) pollen from the anther to the female parts of the plant (stigma), here the pollen grain germinates and grows (down the style) and finally fuses with the haploid female ovule (in the ovary); this results in a fertilized diploid embryo or zygote. A seed coat, the testa forms around each embryo, the ovary wall then becomes thickened; the ovary is in actual fact the "fruit" of the plant, at the wall becomes thickened, the "fruit begins to ripen" with the testa coated seeds inside of it. After ripening the fruit will be eaten, fall from the plant or distributed in another fashion, where finally the seeds will be removed from the fruit. If conditions are right the seed will germinate and form a new plant. Commercially many millions of seasonal, herbaceous plants and trees are produced each year from cultivated seed.

In Gymnospersms the process occurs the cones of the plant

Separate male and female cones are produced on the plant; the ovules (haploid) are not contained in an ovary buy lie "naked" on the scale of the female cone. Pollen (haploid) is produced in male cones. Generally the cones are produced at the tips of branches with the male cones being located in the upper portions of the tree (or plant) and the female cones on the lower portions. Large amounts of pollen are produced and pollination is mainly by wind (and air currents). Once fertilized the seed (diploid) becomes encapsulated by a woody testa within the female cone. Once the seeds are fully formed the cone either detaches from the plant or opens (scales) to release the seed away from the parent plant, or the cone is removed by animals looking for food and seeds distributed in this manner.

Asexual reproductionrefers to the propagation or reproduction of a plant without the exchange of genetic material; this means that all "daughter" plants have the same genetic makeup as the parent plant. This occurs naturally in some plant types, but is one of the main commercial methods or propagating plant materials. Examples of asexual reproduction include: division, various types of cuttings, air layering, offsets, plantlets as well as tissue/ in vitro culture.

Answer 3

Plant reproduce either by producing seeds or off shoots identical genetic copies of the parent plant. Animals require the male sperm to come in contact with the female egg. Mammals give birth to live young, while birds , fish, and amphibians lay eggs.

Answer 4

animal reproduction is when animals reproduce

Answer 5

Animals go full contact! Plants use pollen.

Answer 6

Reproduction in plants and animals differ in terms of how they produce sexually. Plants sexual reproduction is through pollination while animal reproduction is through mating.

Answer 7

animal and plasnt reproduction is similar because they have the same cells
Both reproduce sexually by fusion of gametes
