Answer 1

Explanation:

1. The cell was first discovered and named by Robert Hooke in 1665. He remarked that it looked strangely similar to cellula or small rooms which monks inhabited, thus deriving the name. However what Hooke actually saw was the dead cell walls of plant cells (cork) as it appeared under the microscope.

2. The cell is known as the structural and functional unit of life because all living beings are formed of cells. Cells are very important for performing various life processes which are required for sustaining life on earth. Moreover, cells give form and structure, process nutrients and make it into usable energy.

3. The substances like CO2 and water move in and out of a cell by diffusion from the region of high concentration to low concentration. When the concentration of CO2 and water is higher in external environment than that inside the cell, CO2 and water moves inside the cell.

hope it helps :)

Answer 2

Answer:

1 The cell was first discovered and named by Robert Hooke in 1665

2The cell is known as the structural and functional unit of life because all living beings are formed of cells.

3 The substances like CO2 and water move in and out of a cell by diffusion from the region of high concentration to low concentration. ... When the concentration outside the cell becomes low and it is high inside the cell, they moves out.
