Answers
Answer:
habit => A habitat is a place where an organism makes its home. A habitat meets all the environmental conditions an organism needs to survive. The main components of a habitat are shelter, water, food, and space.
root => the part of a plant that grows downward and holds the plant in place, absorbs water and minerals from the soil, and often stores food. The main root of a plant is called the primary root; others are called secondary roots. Root hairs increase the root's absorbing surface.
stem =>The stem conducts water, minerals, and food to other parts of the plant; it may also store food, and green stems themselves produce food.
leaves => leaves are thin, flat organs responsible for the photosynthesis of the plant.
inflorescence => An inflorescence is categorized on the basis of the arrangement of flowers on a main axis (peduncle) and by the timing of its flowering (determinate and indeterminate).
Flowers => A flower, sometimes known as a bloom or blossom, is the reproductive structure found in flowering plants (plants of the division Magnoliophyta, also called angiosperms). The biological function of a flower is to facilitate reproduction, usually by providing a mechanism for the union of sperm with eggs.
calyx => the usually green outer whorl of a flower consisting of separate or fused sepals is called as calyx.
corolla => all of the petals of a flower are called corolla.
androecium => The androecium is the third whorl of the flower. It is the male reproductive organ of angiosperms. It is made of stamens. Each stamen is composed of a filament and an anther. Anther contains pollen grains or male gametes.
gynoecium => The gynoecium, or female parts of the flower, comprises one or more pistils, each of which consists of an ovary, with an upright extension, the style, on the top of which rests the stigma, the pollen-receptive surface.
fruit => A fruit is a mature, ripened ovary, along with the contents of the ovary.
seed => A seed is a mature ovule that comprises an embryo or a miniature undeveloped plant and food reserves, all enclosed within a protective seed coat.
floral formula => It is sometimes found convenient to describe a flower by a simple and concise formula known as the floral formula. In this formula K represents calyx, C=corolla, P= perianth, A=androccium, G=Gynoecium. The number of members of a whorl is written after the symbol for a whorl, ∞ signifies a large and indefinite number.
