Modification in root
Sometimes in addition to the normal functions of absorption, conduction and anchorage roots may perform storage of food materials, mechanical support and vital functions and this is called modification of root.

Types of leaves
Mainly there are two types of leaves they are; simple and compound leaf. This note contains detail information about types of leaf. Learn More
Inflorescence
The mode of arrangement of flowers on the floral axis is known as an inflorescence. This note contains detail information about inflorescence and its types. Learn More
Flower
Flower is the reproductive part of the angiosperm which consist of four whorls i.e. calyx, corolla, androecium and gynoecium. This note contains detail information of flower. Learn More
Perianth of Flower
The perianth is a non-reproductive part of a flower. It contains both calyx and corolla. This note contains detail information about calyx and corolla. Learn More
Androecium
The androecium is the male reproductive whorl individual unit of which is stamen. This note contains detail information about androecium, its attachment with anther and filament, length of stamen, cohesion of stamen and adhesion of stamen. Learn More
Gynoecium
The gynoecium is a female whorl individual unit of which is carpel. This note contains detail information about gynoecium, carpel, ovary. Learn More
Aestivation and Placentation
Mode of an arrangement of sepals or petals in the bud is known as aestivation. The placenta is the tissue through which ovules remain attached to the ovary wall and get nutrition. This note contains detail information about aestivation and placentation. Learn More

Family- Compositae
This is the largest family of angiospermae which includes 1100 genera and over 20,000 species. This note contains detail information about Family Compositae. Learn More
Fruits
This note provides information about types of fruits and seeds. Fruits may be defined as the matured ripened ovary containing seeds. It consists of two parts, pericarp that is a fruit wall and is differentiated into three layers which are outer epicarp, middle mesocarp, and innermost endocarp. The fruit which develops without fertilization is called parthenocarpic fruit. Eg: banana. There are two types of fruits: true fruits which develop from the ovary of a flower and false fruit that develops from the fusion of floral parts with the pericarp. Learn More© 2019-20 Kullabs.
