Biology / Flowering plants

Biology / Flowering plants

„ Living things give birth to young ones by the process called reproduction. Plants reproduce asexually by - budding, spore formation, fragmentation.
Vegetative reproduction (vegetative part give rise to new ones) through leaf or stem or root
Artificial vegetative propagation- growing plants using artificial methods such as cutting, layering and grafting. Tissue culture is a modern method of vegetative reproduction.
Sexual reproduction - Flower is the reproductive part of a plant.
Flowers are classified based on the shape and symmetry as actinomorphic, zygomorphic and asymmetrical.
Male part of flower is stamen - filament, anther. Anthers have pollen grains, which are the male sex cells.
Female part of a flower is pistil - It has ovary, ovules, style, stigma. Ovules contain egg cell (placenta). The arrangement of placentae within the ovary is termed as placentation.
Also learn about types gynoecium - Apocarpous and syncarpous.
You might have observed sometimes the stalk bares single flower or two or more than two isn't it? Yes they are arranged in different ways. The arrangement of flowers on their floral axis is known as infloroscence. Lets have a look on types of inflorescence such as racemose(ex-coriander flower) and cymose(ex- jasmine flowers).
Modern methods of growing plants:
Hybridization - Its a technique of plant breeding to bring about crop improvement and its benefits.
Micropropagation-culturing cells in a culture medium. Learn about its uses and limitations.

Germination of seeds: You know the life of a plant starts with seed. It matures and gets enclosed in a fruit. You will learn about the seed types as monocot(single cotyledon) and dicot(two cotyledons).
The Seed then germinates under favourable conditions like air, water, and optimum temperature . Germination may be either epigel or hypogel germination.
Epigeal - cotyledons come above the surface of the soil
hypogeal - seed remains inside the soil
