A cell wall surrounds the plasma membrane in all plant cells. It is a porous covering of about 0.1 milli microns to 10 milli microns in size. The cell wall is chiefly composed of insoluble polysaccharides. The most common constituent is cellulose. Certain oth..

Animal cell Plant cell Usually smaller in size Usually larger in size Cell wall is absent. Cellulose in any form is absent Cell wall made up of cellulose is present Cytoplasm is denser, more granular and occupies most of the..

Cell Theory - Two German biologists M.J.Schleiden (1838) and Theodore Schwann (1839) proposed the cell theory (or cell doctrine), which unified the ideas prevailing at that period on the organisation in plants and animals. The cell theory states tha..

Scientists have genetically engineered agronomically important crop plants, using the meristematic cells..

A tissue is an aggregation of cells that have a common origin and structure, and perform similar functions. Tissues are meant for meeting the physical and physiological needs of the plant bod..

In case of plants, growth and development is in a coordinated manner. The higher plants do not show locomotion. However, locomotion is seen in structures like sperm cells of ferns and mosses that swim towards the egg. The other movements shown by the plantsh..

Many years ago, Frederick Steward and his co-workers cultured cells from carrot plants and induced some of them to develop into small embryos. Some of these embryos grew into whole plants. Today, researchers routinely regenerate crops, plants and many other h..
