Sexual reproduction is a type of reproduction that involves a complex life cycle in which a gamete (such as a sperm or egg cell) with a single set of chromosomes (haploid) combines with another to produce a zygote that develops into an organism composed of cells with two sets of chromosomes (diploid).

Sexual reproduction in flowering plants involves the production of separate male and female gametophytes that produce gametes. The anther produces pollen grains which contain male gametophytes. The pollen grains attach to the stigma on top of a carpel, in which the female gametophytes (inside ovules) are located.
Most plants sprout bisexual flowers (which have both male and female parts), but plants like squash grow separate male and female flowers — still others have both bisexual and single-sex flowers. And, as evolutionary biologists have recently discovered, plants with male and bisexual flowers produce more seeds.
Plants can reproduce asexually in a variety of ways. Learn about bulb, gemma, plantlet, and cutting forms of asexual plant reproduction. Both homosporous and heterosporous life histories may exhibit various types of asexual reproduction (vegetative reproduction, somatic reproduction).

Are animals asexual or sexually?
All animals can reproduce sexually, but some can do both ways. Colonial animals such as siphonophores, corals, and bryozoans are particularly good at asexual reproduction, but like everything else they can reproduce sexually.
The transfer of pollen from the anther to the stigma of a flower is called pollination. During fertilization, the male and female germ cells of the pollen unite to form a zygote. A zygote then transforms into an embryo, which eventually becomes a seed. The seed then germinates into a new plant.
Aloe vera can reproduce asexually through offsets (small, complete daughter plants produced on the mother plant) or sexually through flowers. The aloe has flexibility in reproduction to increase its chances of reproduction.
The reason for this is that, despite the lack of any kind of cognition, plants have souls too, according to Aristotle's widely-accepted theory: trees and flowers nourish themselves, they grow, and propagate, and so they have what was usually called a vegetative soul.
Plants may not have feelings but they are indeed alive and have been described as sentient life forms that have “tropic” and “nastic” responses to stimuli. Plants can sense water, light, and gravity — they can even defend themselves and send signals to other plants to warn that danger is here, or near.
The sexual reproduction in rose plants happens with the fusion of male and female gametes produced by plants. The male gametes are produced by the process of microsporogenesis which occurs in anthers whereas the female gametes or eggs are produced in the ovary of the flower.
Lavender officinale, also called fine lavender or true lavender, has short floral stems, without branching. It flowers from late June to late August according to the altitudes and climatic conditions. Lavender has a sexual reproductive system and gives seeds.
There are several methods of asexual reproduction such as fragmentation, budding, spore formation and vegetative propagation. Sexual reproduction involves the fusion of male and female gametes. In vegetative propagation new plants are produced from different vegetative parts such as leaves, stems and roots.
Strawberries, like many flowering plants, can produce both sexually and asexually. Farmers rely on both traits: sexual reproduction produces fruit, whereas asexual reproduction provides breeders with clones of useful strawberry varieties.
Some plants, like ferns and mosses, grow from spores. Other plants use asexual vegetative reproduction and grow new plants from rhizomes or tubers. We can also use techniques like grafting or take cuttings to make new plants.
Tubers. Tubers, such as potatoes, are fleshy underground storage structures composed of enlarged parts of the stem. A tuber functions in asexual propagation as a result of the tiny scale leaves equipped with buds that grow on its surface. Each of these buds can form a new plant, genetically identical to the parent.
In order for the cactus to reproduce, its pollen must fertilize an egg cell in the female part of the plant. Birds, bats, and insects are attracted to the bright colors or the scent of cactus flowers. While feeding, these creatures transfer pollen from one part to other parts of the plant.
While many types of aloe grow offsets, some types just don't produce pups – it isn't in their makeup. A few of these non-pup types include coral aloe (Aloe striata), tiger tooth aloe (Aloe juvenna), and fez aloe (Aloe peglerae).
Aloe Vera leaves have a lot of moisture, and tend to rot before they can take root. Growing an Aloe Vera plant from an "offset" is more effective. Aloe can be grown from cuttings, but it needs to be a stem cutting, not a leaf cutting.
The male plant frequently grows taller than its female counterpart and has thicker, sturdier stalks to support its weight. Male plants also have fewer leaves than female plants, which tend to be shorter and bushier.
A seedling is a young sporophyte developing out of a plant embryo from a seed. Seedling development starts with germination of the seed. A typical young seedling consists of three main parts: the radicle (embryonic root), the hypocotyl (embryonic shoot), and the cotyledons (seed leaves).
Yes, flowering plants can reproduce by asexual means of reproduction. There are many flowering plants, which are able to propagate themselves using asexual mode of reproduction. During the process of asexual reproduction in flowering plants, there is no involvement in pollen grains and fertilization.
