Living things give birth to young ones by the process called reproduction.
Plants reproduce in two ways Asexual reproduction 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 of gynoecium - Apocarpous and syncarpous.
You might have observed some stalks bare only a single flower while others have two or more? The arrangement of the flowers is also different. 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
