Plant Reproduction

The stomata are pores in leaves. They are responsibe for gas exchange. These are  special type of pore opening on leaves of plants. They are designed to absorb water from sources such as rain while also removing excess water in the plant through transpiration.

A flower, is also  known as a bloom or blossom. It is the reproductive structure found in flowering plants. All plants produce flowers for the same reason i.e. to make seeds so another plant can grow. A flower is the part of the plant that makes seeds.

Tomato  is definitely a fruit. True fruits are developed from the ovary in the base of the flower, and contain the seeds of the plant (though cultivated forms may be seedless). Blueberries, raspberries, and oranges are true fruits. However in cooking it is generally considered as a vegetble.

Cherry trees belong to the Rosaceous family of plants and are native to regions around the Northern Hemisphere.It is a tree of the subgenus Cerasus, the members of which are valued agriculturally for their fruit, the cherry. The wood of the tree, cherrywood, is also valued in woodworking.

Generally vegetative propagation occurs through root or stem, bue Bryophyllum is an exception where it takes place through the leaf. Small plants develop at the margins of the leaves.The plantlets fall off the leaf and will grow into a new plants if the conditions are suitable.

Pollen grains are minute grains, usually yellow in color but occasionally white, brown, red, or purple, borne in the anther sac at the tip of the slender filament of the stamen of a flowering plant or in the male cone of a conifer. The pollen grain is actually the male  gametophyte.Pollen grains may have furrows, the orientation of which (relative to the original tetrad of microspores) classify the pollen as colpate or sulcate.

The flowering plants or angiosperms (Angiospermae or Magnoliophyta) are the most diverse group of land plants. The flowering plants and the gymnosperms are the only extant groups of seed plants.

Petals are modified leaves that surround the reproductive parts of flowers. They often are  brightly colored or unusually shaped to attract pollinators. Together, all of the petals of a flower are called a  corrola.

A bud is an undeveloped or embryonic shoot and normally occurs in the axil of a leaf or at the tip of the stem. Once formed, a bud may remain for some time in a dormant condition, or it may form a shoot immediately where as a seed is a small embryonic plant enclosed in a covering called the seed coat, usually with some stored food. It is the product of the ripened ovule of gymnosperm and angiosperm plants which occurs after fertilization and some growth within the mother plant.

Vegetative propagation, the ability of plants to reproduce without sexual reproduction, by producing new plants from existing vegetative structures. Many plants are able to tide over unfavourable conditions. This is because of the presence of organs of asexual reproduction like the tubers, corm, bulbs, etc.

Sugar cane propagation is through stem cuttings of immature canes 8-12 months old. These are called setts, seed, seed- cane or seed-pieces. The setts are best if taken from the upper third of the cane because the buds are younger and less likely to dry out. The setts can be planted at a 45 degree angle or laid horizontally in a furrow.

Some cells split via budding (for example baker yeast), resulting in a 'mother' and 'daughter' cell. The offspring organism is smaller than the parent. Budding is also known on a multicellular level; an animal example is the hydra which reproduces by budding. The buds grow into fully matured individuals which eventually break away from the parent organism.

The megagametophyte produces the egg cell for fertilization. After fertilization, the ovule develops into a seed. It is also called embryo sac in flowering plants.
