2. Position of algae :
According to five king dome classifiction system whish was suggested by Ropert wittaker in the 5 kingdoms were ( monera , protista , plants ,animals ,fungi) . So algae included in kingdome monera wich contains cyanophyta or blue green algae and kingdom protista which contains all other groups of algae.

3. Classification of algal division based on:
1-biochemical criteria: A-pigments. B-storge products. C- cell wall composition. 2-morphologi criteria. 3-genetic differences. 4-many can survive desiccation for several years or have resting stages that can do so.

4. Classification: 1 . monera Kingdome: (cyanobacteria) Cyanophyta.
2. protista Kingdome:
A. Euglenophyta
B. Chlorophyta ( green algae)
C. Chrysophyta( yellow – green)
D. Bacillariophyta (diatoms)
E. Phaeophyta ( brown algae)
F. Rhodophyta ( red algae)

5. (cyanobacteria) Cyanophyta
Blue-green or cyanobacteria are microscopis cell that grow naturally in fresh and salt water.
They are a type of bacteria, but som ways act like plants by photosynthesis.
They grown in dams , Rivers ,creeks ,reservoirs, lakes and hot spring.

6. Kingdom : Monera Division : Cyanophyta Class : Cyanophyceae Order : Chroococcales Family : Chroococcaceae Genus : 1- Chroococcus

7. 1- Chroococcus 1-occurs in colonies of 2-4 cells.
2 – the cells are generally spherical to hemispherical
3-independent of one anthor
4-each cell in the colony produced a gelatinous thin sheath of its own.and each colony also.

11. Kingdom : Monera
Division : Cyanophyta
Class : Cyanophyceae
Order : Chroococcales
Family : Chroococcaceae
Genus : 2- Gloeocapsa

12. 2- Gloeocapsa
1- ehch cell is more or less spherical in shpe and surrounded by concentrically layered sheth of of mucilage
2-these sheaths unite the cell into extensive gelatinous colonies.

17. Kingdom : Monera
Division : Cyanophyta
Class : Cyanophyceae
Order : Chroococcales
Family : Chroococcaceae
Genus : 3- Microcystis

18. 3- Microcystis
1- large numbers of spherical cell are held within a commoon mass of mucilage
2- the colonies are always free – floating.

22. GOOD LUCK
