TOPIC 4-CELL STRUCTURE AND ORGANIZATION
The Cell is a basic unit of life.
All living things(Plants and animals) are composed of cells which carry out the process that makes the organism a living entity.
All cells are basically the same in chemical composition.
All life processes take place in the cells.
Some organisms are made up of many cells and are called multicellular organisms e.g. man, pine tree, locust.
Others have one cell e.g Amoeba, they are called unicellular organisms.
All cells are microscopic, their membrane bound has structures that are sites for chemical reactions called organisms.
They have the ability to replicate, since they contain the genetic materials.
So these are characteristics of a cell.
Characteristics of the cell include the following:
Cells are small microscopic structures which cannot be seen by our naked eyes.
Cells are capable of dividing by mitotic process or meiotic process.
Cells contain structures called organelles.
