Notes

Introduction to Cell

The cell is the basic structural and functional unit of life. This note contains detail information about the cell, its discovery, theory and types.

Structure of Prokaryotic Cell

A prokaryotic cell shows various structures. This note contains detail information about various structures of the prokaryotic cell.

Cell wall

The cell wall is a thick rigid protective layer surrounding all plant cells except gametes and zoospores. This note contains detail information about cell wall of the eukaryotic cell.

Cell membrane of Eukaryotic Cell

The cell membrane is a thin elastic transparent semi-permeable membrane covering all cells plants and animals. This note contains detail information about its structure and functions.

Cytoplasm

Cytoplasm is jelly-like semi-fluid or ground substance which is differentiated in two parts; cytoplasmic matrix and cytoplasmic structure. This note contains detail information about cytoplasm.

Flow of energy and information through the cell.

This note includes information about energy and information through the cell. Energy in living organisms flows through chemical reactions. Each step in chemical reaction involves conversion of a set of substances, known as the reactants, into specific products. During chemical reactions, energy stored in chemical bonds is transferred to other, newly created chemical bonds.
