Question

1. ______ provides structure and support to plant cells
2. ______ produces proteins and transports them
3. ______ stores materials like water and nutrients

Explanation:

Question 6

In plant cells, the cell wall is a rigid structure outside the cell membrane that gives the cell its shape and provides structural support. It also helps in protecting the cell and maintaining turgor pressure.

The rough endoplasmic reticulum (rough ER) has ribosomes attached to its surface. Ribosomes are the sites of protein synthesis, and the rough ER then transports the newly synthesized proteins to other parts of the cell or for secretion outside the cell.

In plant cells, the vacuole is a large organelle that stores various substances including water, nutrients, and waste products. It also helps in maintaining the cell's turgor pressure and can play a role in cell growth and storage of pigments. In animal cells, there are smaller vacuoles, but the central vacuole in plant cells is the main storage organelle for water and nutrients.

Answer:

Cell Wall
