Write a short note 1) cytoplasm …

Cytoplasm

• A thick solution composed of water, salts, and proteins that fills the cell is called cytoplasm.
• It is surrounded by cell membrane.
• The nucleus of the cell is surrounded by the cytoplasm

Golgi apparatus

• The stacks of flattened membranous vesicles are called Golgi apparatus.
• It basically stores, packs and modifies the products in vesicles.
• It temporarily stores protein that moves out of the cell through the vesicles of the Golgi apparatus.
• It packs and transports the materials synthesised in Endoplasmic Reticulum to different targets inside and outside the cell.

Endoplasmic reticulum

• The large network of membranous sheets and tubes is called endoplasmic reticulum.
• They are filled with fluids and carries materials throughout the cell due to which it is also called transport system of the cell.
• It transports materials between the regions of cytoplasm or between the cytoplasm and nucleus.
• It also provides a surface for some biochemical activities of cell.
• It can be classified into two types:
• RER (Rough Endoplasmic Reticulum)
• SER (Smooth Endoplasmic Reticulum)
