Introduction
PROCARYOTIC - EUCARYOTIC CELL STRUCTURE
Cell is a smallest unit of living things. And like you know all animals, plants, fungies and all living things made of cells. Basicly we classify cells into two groups. They are procaryotic and eucaryotic cells.

Task
PROCARYOTIC CELLS - Prokaryotes are single-celled organisms that are the earliest and most primitive forms of life on earth. Prokaryotic cells are not as complex as eucaryotic cells . They have no true nucleus as the DNA is not contained within a membrane or separated from the rest of the cell, but is coiled up in a region of the cytoplasm called the nucleoid.
Example of procaryotic cell, Escherichia coli :
EUCARYOTIC CELLS- Eukaryotic cells, while very similar in function to prokaryotic cells, are much larger and more complex. Eukaryotic cells are called so because they have a true nucleus . The nucleus, which houses DNA , is contained within a membrane and separated from other cellular structures.
Example of eaucaryotic cell, liver cell :

FUNCTIONS OF ORGANELLES IN EUCARYOTIC - PROCARYOTIC CELLS
1) the Prokaryotic Bacterium Escherichia coli :
Cell wall
- Support (grow tall)
- Protection
- allows H2O, O2, CO2 to diffuse in & out of cell
Cytoplasm
- Supports and protects cell organelles
Ribosome
- Synthesizes proteins
2)eukaryotic liver cell
nucleus:
- Controls cell activities
- Contains the hereditary material of the cell
Nuclear membrane :
- Controls movement of materials in/out of nucleus
Cytoplasm :
- Supports and protects cell organelles
Endoplasmic reticulum (ER) :
- Carries materials through cell
- Aids in making proteins
Vacuole:
- Store food, water, metabolic & toxic wastes
- Store large amounts of food or sugars in plants
Lysosome:
- Breaks down larger food molecules into smaller molecules
- Digests old cell parts
Golgi Apparatus:
- Modify proteins made by the cells
- Package & export proteins
Evaluation
so from taht pictures we can see the differences between them and the function of organelles.
