Solution

Cell biology:

1. Rough endoplasmic reticulum.

2. Membrane bound organelles:

   Nucleus

Mitochondria

Chloroplast

3. End membrane system:

Nuclear envelope

Rough endoplasmic reticulum (making secretory proteins)

Smooth endoplasmic reticulum (steroids production and detoxification reaction)

Golgi apparatus

Vesiclese(Transport endoplasmic reticulum to the Golgi apparatus).

Lysosome

Vacuoles

Plasma membrane

4. Cell surface and junction:

Cell wall

Plasmodesmata (In plants it helps in communication between adjacent plants)

Gap junction (animal communication)

Tight junction (In animal it connects plasma membrane of adjacent cells)

Gap junction (current passing through the gap junction do not leak into the intercellular space)

Tight junction (In animals prevent the contents of these organs from leaking into the surrounding tissues)

5. Cytoskeleton:

Microtubules 25 nm

Microfilament 7 nm

Intermediate filaments 8-12 nm
