Answer 1

The questions can be answered as follows:

Explanation:

• The most important function of cell membrane is that it (a) controls the entry and exit of materials from cells. Cell membrane allows the entry of only those materials that are required by the cell and small.
• The correct statement is (a) Tissue is a group of similar cells. A group of cells that work together to perform a particulat function are referred to as tissue.
• The cell that Paheli observes is (d) bacterial cell. A bacterial cell has a cell wall n=but not a define nucleus as it is a prokaryote.
