Question

Cell organelles embedded in cytoplasm​

Answer 1

Cell organelles:

Endoplasmic Reticulum

• Endoplasmic reticulum is a network of tiny tubular structure scattered in the cytoplasm.
• They help in mechanical support
• Helps in forming endoskeleton of cell
• Rough ER helps in protein synthesis.
• Smooth ER helps in lipid synthesis

Golgi Complex:

• This organelle packs materials which are to be delivered to inter-cellular targets or to outside the cell
• They remain in close association with the ER
• They form the glycoproteins and glycolipids

Lysosomes:

• These membrane bound structures are formed in golgi apparatus
• They are rich in hydrologic enzymes
• They function actively at pH=5

Vacoules:-

• These are membrane bound organelles
• The vacoules is bound by a single membrane called tonoplast
• In plant cell vacoules can occupy 90% of the cell

Mitochondria:

• Number of mitochondria depends upon the activity of the cell.
• Mitochondria are known as "power house of the cell"
• It's the site of aerobic respiration and ATP production

Plastids:

• They are present in plant cells and in euglenoids
• They bear specific pigments
• They impart colour to plants
• They help in photosysnthesis

Ribosomes:

• Except RBC all living cells have ribosomes.
• They are called "protein factory of cell"
• Several ribosomes may attach to a single mRNA and form a chain called polysome.

Answer 2

The following are the cell organelles embedded in the cytoplasm:

• Endoplasmic reticulum
• Ribosomes
• Mitochondria
• Golgi apparatus
• Lysosomes
• Centrosome and centrioles
• Plastids
