Cell is a simple unit of life surrounded by a membrane that contains macromolecules and molecules associated with each other.
<h3>What is cell?</h3>
The smallest unit that makes up all living organisms and the tissues of the body. A cell consists of three main parts i.e. the cell membrane, the nucleus, and the cytoplasm. The cell membrane surrounds the cell and its function controls the substances that go inside of cell and out of the cell. A nucleus is the membrane that enclosed organelle within a cell which contains the genetic material. The cytoplasm is the gel-like fluid inside the cell that provides a medium for chemical reaction.
So we can conclude that Cell is a simple unit of life surrounded by a membrane that contains macromolecules and molecules associated with each other.

Answer:
Sex cells are the only cells that undergo meiosis.

Sperm cells in male and egg cells in female are the sex cells because these cells are responsible for the formation of new organism. When the sperm sex cell fuse with egg sex cell forming zygote which turns into a new organism. Mitosis occurs in somatic cells while meiosis occurs only in sex cells.
Evaporation of the water is the process that exerts the pull on water molecules that is relayed from leaf to root via cohesion. The pressure of the water present in the leaves becomes less due to evaporation of water. The pressure of water in the roots and lower part of the shoot is high. This gradient of pressure creates a pull on the water molecules present in the roots to move upwards to the leaves to occupy the vacant space. The whole process is called transpiration.
B. One
because an independent variable is something you change. So in a scientific experiment you only change one thing. If you happen to change more than one thing then the test becomes unfair therefore you should repeat and make sure that only one thing is changed this time.
