Life-sustaining processes and survival of species Reproductive mechanisms in plants

What is asexual reproduction in plants It can happen naturally or artificially through cutting or layering. It can also happen through a special organ, like a bulb (e.g. tulips) or a tuber (e.g. potatoes).

Example of asexual reproduction Cutting: One part of the plant (stem, leaves, roots) is cut off and takes root.

Example of asexual reproduction Layering : A stalk takes root in the soil without detaching from the plant.

Example of asexual reproduction Reproduction through bulbs: A bulb is a sort of bud that ensures life in slow motion.

Example of asexual reproduction Reproduction through tubers : A Tuber is a round stem. Each of its buds can turn into a new stem.

What is sexual reproduction in plants It is the main way that plants reproduce. This varies depending on the type of plant: for example, ferns use spores, evergreens use pinecones, and flowering plants use flowers.

Flowering plants, sexual reproduction stages

Parts of a flower Stamen : Flower’s male organ Pistil : Flower’s female organ

Part of a flower Stamen is composed of: Filament (long stem) Anther (covered of pollen) Pollen (Sperm)

Part of a flower Pistil is composed of: Ovary (contains ovule) Style (Long tube) Stigma (Entrance of the pistil)

Part of a flower Petals (bright colour = attract insects) Sepals (support for the flower) Peduncle (support for the flower) This flower has both male and female parts. However, in some species, there are male flowers and female flowers.
