 * __The Organelles of the cell 2__**


 * __Golgi Apparatus:__**

Its function is the processing, packaging and secreting organelle of the cell. Like the endoplasmic reticulum its a system of membranes. The Golgi Apparatus appears under a microscope to have a series of flattened sacs with a convex shape. Its major function is to modify protein for the export by the cell.



**__Cilia and Flagella:__** Cilia and flagella are both hair-like organelles that extend from the surface of the cell, where they assist in movement. they are short in size but present in large numbers inside the cell. The external surfaces of many unicellular organisms are covered by Cilia, as well as the surface of many multi-cellular organisms. the cilia is also found in the lining of our respiratory system, because it traps particles such as dust from entering our body. While the flagella are also hairlike organelles that are long but less numerous in a cell. They are basically found in sperm cells.

Review Chapter: 1) What structural features are common between cilia and flagella? 2) How is the function of the Golgi apparatus and the endoplasmic reticulum related? 3) Make a little search on the internet and describe how the structure of the plant cell differs from that of the animal cell?


 * Leen: **

1. a) Cilia and flagella are both hairlike organelles that extend from the surface of the cell b) They are both present in cells.

2. Their function is the processing, packaging and secreting organelle of the cell.

3. a) Animal cells always have cilia while the plant cells rarely do. b) Animal cell has one or more small vacuole(s) while plant cell has one large vacuole. c) Animal cells don't have cell wall while plant cells do. d) Animal cells do not have plastids while plant cells do. e) Animal cells don't have chloroplast while plant cells do because they make their own food.

1) Both are present in large amounts in cells, and both have hair like organelles each for its own work. 2) Both are involved in the processing, packaging and secreting organelle of the cell 3) I- Animal cells are smaller in size than plant cells II- Plant cells are rectangular, animal cells are circular  III- Plant cells have a rigid cell wall, animal cells do not have cell walls  IV- Plant cells have chloroplast, animal cells do not have chloroplast
