Secondary Growth:
Secondary growth is absent in monocotyledons, but present in dico
Out of 105 elements discovered so far, less than 21 are essential and beneficial for normal plant growth and development.

Post Fertilization Events:
Events in sexual reproduction after the fertilization (formation of zygote) are called post fertilization events. These events may be d
Water provides medium in which many substances are dissolved. Protoplasm of cell is consist of water in which different molecules are dissolved and suspended.

Plant Breeding Program:
This breeding program has a series of events that take place to achieve desired variations in a species:
Life Cycles
Life cycles differs in the duration of haploid and diploid phase. There are three types of life cycles:
(A) Haplonti
Active Transport: Uses energy to pump molecules against a concentration gradient. Casparian strip presents in the endodermis (the i
In plants, special long distance transport is necessary as sites of production or absorption and sites for storage too far and at much faster rate. This is generally done by m

Microbes as bio-fertilizers:
Bio-fertilizers are the micro-organisms which increases the nutrient quality of soil. The main source
Tissue culture:
It is a laboratory technique, of regeneration of a whole plant from any part of plant by growing on a culture plate with sterile (
Organic chemistry is that branch of chemistry which deals with the study of compounds of carbon with hydrogen (hydrocarbons), and their derivatives.
Process of Recombinant DNA Technology
Recombinant DNA technology involves the following steps:
Forms of Stem:
Strong Stem:
The following terms are important in relation to strong stems.
Taxonomical Aids
Taxonomy is the branch of biology that deals with identification, naming, and classification of organisms.
