Cytoplasm

key notes :

What is Cytoplasm?

• Cytoplasm is a jelly-like substance found inside all living cells.
• It fills the space between the cell membrane and the nucleus.
• Cytoplasm plays a crucial role in the functioning of the cell.

Composition of Cytoplasm:

• It mainly consists of water (about 70-80%).
• It contains various molecules, including proteins, sugars, salts, and other organic compounds.

Functions of Cytoplasm:

1. Support and Shape: Cytoplasm provides structure to the cell, helping it maintain its shape.
2. Transport: It serves as a medium for the movement of various substances within the cell, including nutrients and waste products.
3. Chemical Reactions: Many essential cellular processes occur in the cytoplasm, such as glycolysis, a critical step in cellular respiration.
4. Storage: Cytoplasm can store important molecules and ions needed for cellular activities.
5. Cellular Activities: Most cellular organelles, like the ribosomes, are suspended in the cytoplasm and play essential roles in protein synthesis.

Notable Features:

• Cytoplasm is semi-fluid, allowing organelles to move within the cell.
• It contains small structures called ribosomes, where proteins are made.
• The cytoplasm is involved in processes like cell growth, repair, and reproduction.

In Summary:

• Cytoplasm is a vital component of the cell that supports its structure and numerous functions.
• It acts as the cell’s bustling factory floor, where many essential processes occur.
