A cell can be defined as the protoplasm surrounded by cell membrane, which works as a structural and functional unit of life. The outermost, rigid, protective layer found in cells is known as the cell wall. The non-crystalline, translucent substance found in between the plasma membrane and nucleus is known as cytoplasm. This note provides us the information about cell and various parts of the cell.
Tissue may be defined as a group or layer of similarly specialized cells which together performs certain special functions. A group of plant cells performing essentially the same function and common to similar structure is a plant tissue. This note provides us the information about plant tissue and its types.
