Definition

+

Reproduction is a biological process for organisms in order to preserve its kind.

+ +

How Organisms Reproduce

+

Reproduction in organisms are divided into 2, vegetative and generative reproduction.

+

Vegetative Reproduction

+

A vegetative reproduction is any form of reproduction that don't preceded by the male and female sex cells.

Division is a reproduction method by dividing itself, usually done by single-celled organisms (protozoa) such as amoebas and paramecium.

+

Spore

+

Spore is a reproduction method done by some plants such as moss, fungi, and ferns.

+ +

A bud is the base of stem on a plant such as hydras, or bananas (for higher and more complex organisms) that will develop into other organs.

+

Adventitious buds is a wild bud that doesn't grow on the stem, but grows on the side of the leaves or roots, such as Kalanchoe pinnata.

+

Stolon

+

Stolon is a stem that spreads over the land surface. Plants that reproduce this ways are Cyperus rotundus, Centella asiatica, and more.

+

Rhizome

+

Rhizomes are stems that grow under or on the soil, such as ginger, tumeric, curcuma, and more.

+

Generative Reproduction

+

Generative reproduction is a form of reproduction that invovles the meeting of a male and female sex cells (sperm and ovum), or mating. Organisms that reproduce generatively are: humans, flowering plants, mammals, and many more.
In plants, there are 2 types of pollination, which is self-pollination (autogamy, and geitonogamy), and cross-pollination.
