2. Why is the cell called the
structural and functional unit of
life?
Answers
Answer:
Answer: It was Robert Hooke who discovered cells. He observed the cells in thin slices of cork. They appeared like small compartments when viewed through the microscope
2) A cell is capable of carrying out all the life functions; such as nutrition, excretion, respiration, etc. Hence a cell is called the functional unit of life. Additionally, the cell is the smallest unit of life and all the living beings are made up of cells. Hence a cell is called the structural unit of life

Answer:
1)Ans - 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)Ans - Cell is known as structural and functional unit of life because living organism is the formed of cell and all the physiological, biochemical, genetic and metabolic function take place inside the cell. It is the smallest functional unit which can exist independently.
