Cells are the basic unit of structure and function in living things.

TYPES OF CELLS

1. BACTERIAL CELL

• Is a prokaryote cell
• 5 essential structural components:
• Nucleoid
• Ribosomes
• Cell membrane
• Cell wall
• Surface layer

2. PLANT CELL 3. ANIMAL CELL

These are eukaryotic cells.

They have defined a nuclear membrane which contains its genetic material core.

Its size is much larger than the prokaryotic cell.

In the cytoplasm there are structures that have diverse functions called cellular organelles.

The animal cell do not have a cell wall.

the plant cell have cell wall or chloroplast

Animal cells are round and irregular in shape.

Plant cells are rectangular shape.
