Answer:

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.

Explanation:

1.Endoplasmic reticulum:

A network of membranous tubules within the cytoplasm of a eukaryotic cell, continuous with the nuclear membrane. It usually has ribosomes attached and is involved in protein and lipid synthesis.

2.Lysosome:

An organelle in the cytoplasm of eukaryotic cells containing degradative enzymes enclosed in a membrane.

They digest excess or worn out organelles, food particles, and engulfed viruses or bacteria. Lysosomes are like the stomach of the cell.

3.Vacuoles:

A space or vesicle within the cytoplasm of a cell, enclosed by a membrane and typically containing fluid.

In mature plant cells, vacuoles tend to be very large and are extremely important in providing structural support, as well as serving functions such as storage, waste disposal, protection, and growth.

4.Golgi apparatus:

A complex of vesicles and folded membranes within the cytoplasm of most eukaryotic cells, involved in secretion and intracellular transport.

A major function is the modifying, sorting and packaging of proteins for secretion.

5.Plastids:

Any of a class of small organelles in the cytoplasm of plant cells, containing pigment or food.

Their main function is the storage of food.
