Question

Taking Amoeba as an example,justify that cell is the structural and functional unit of life.Why does Amoeba have pseudopodia??

Answer 1

Amoeba have pseudopodia also known as false feet to move around and also for eating food and to egest it.

Answer 2

Answer:

Cells are known as the 'structural and functional' units of life. They are responsible for various metabolic cycles in the body. These help to sustain a living being and assist them in day-to-day activities.

Amoeba have pseudopodia for locomotion.

Explanation:

Cells

• Cells are the basic units that form organ systems on accumulation. Organ systems oversee significant bodily processes - respiration, circulation, digestion, coordination, excretion, etc.
• There are two types of organisms depending on the number of cells they have - Unicellular and Multicellular.
• As the names suggest, unicellular organisms have only one cell. All the activities are performed by this single cell.
• Amoeba is a unicellular organism and even thrives on this planet today. Amoeba acts as evidence that the cell indeed is the 'structural and functional' unit of life.
• It being a single-celled organism is no less than being a multicellular one.  

Pseudopodia

• It is difficult for a single cell to be a locomotory organ as well.
• Hence, when an amoeba needs to move from one place to another, it extends a part of its body as rays that work as feet.
• These are called pseudopodia, meaning 'false feet'.
