Plant Growth And Development
The process of plant development starts right from germination under favourable environmental conditions. Generally, plant growth is indeterminate as they retain their capacity to grow throughout their lives because of the presence of meristems. The growth of plants is, however measurable through parameters such as – dry weight, increase in fresh weight, length, area, volume,…

Respiration In Plants
Food that is required for life processes comes from photosynthesis. Cellular respiration results in the release of energy used for the synthesis of ATP which involves glycolysis. Aerobic respiration leads to complete oxidation of organic substances in the presence of oxygen, which is common in higher organisms. To release and utilize the energy stored in…

Photosynthesis In Higher Plants
Plants synthesize their own food through photosynthesis and hence are called autotrophs. Photosynthesis is important since it is the primary source of food for all living entities on earth and it releases oxygen in the atmosphere which we inhale to breathe. It takes place in chloroplasts through light and dark reactions using 4 pigments- Chlorophyll…

Mineral Nutrition
Plant nutrition is an important aspect instrumental in the growth of plants. It gives an insight into the methods used to identify essential elements for the development of plants, the role of these elements, criteria to identify their essentiality, deficiency symptoms and mechanism of absorption of these elements. It also conveys the importance of nitrogen…

Transportation In Plants
Plants have a distinct vascular system (xylem and phloem) which helps in transporting nutrients and water from roots to all the parts of the plant through translocation. Transport of water and nutrients in rooted plants is unidirectional or multi-directional. Modes of transportation can either be passive which occurs through diffusion, facilitated diffusion to be precise…
-
Xylem and Phloem
These form the vascular tissues of the plant. These are also known as sap. They transport water, sugars and other important substances between the roots, stem and leaves.
-
Roots
The roots are an underground part of the plant that absorbs water and nutrients from the soil. That is why they are an important part of the plant.
-
Stem
The stem provides support and structure to the plant. They perform many important functions such as plant growth, compete and survive in different environments, etc. The structure of the stem differs in different species.
-
Leaves
Leaves are an important organ of the plant. They can grow in a variety of shapes and sizes. They are the primary centre of photosynthesis.

Plant Physiology
Plant physiology is a branch of study in Botany dealing with the physiological processes or functions of plants. Precisely, it is a descriptive study of variation and structure of plants at the molecular and cellular level, resulting in ecological, physiological and biochemistry related aspects of plant exploration. With terrestrial plants evolving, special techniques and procedures…
