Question

FIVE(5) MARK QUESTION:
Q.13.(a) Which cell organelle is known as "Power House of the Cell” and Why?
(b) Which cell organelle is known as “Suicidal bag of the Cell” and Why?
(c) Name the Energy Curreney of the cell.
(d) Give any two differences between Bacterial Cell and Onion Peel Cell.​

Answer 1

Answer:

a)Mitochondria are tiny organelles inside cells that are involved in releasing energy from food

b)Lysosomes are organelles with an acidic lumen containing hydrolases, whose role is to break down macromolecules into their subunits.

c)ATP

d)Onion cell is a eukaryotic cell with well-defined membranes around the organelles whereas Bacterial cell being a prokaryote has a primitive form of the body, which shows no membranes around the organelles and the nucleus.

Explanation:

Answer 2

Answer:

(A)

Ans= Mitochondria is the cell organelle and is called the Powerhouse of the cell as they carry out the cellular respiration and generate the energy molecules called ATP or Adenosine Triphosphate.

(B)

Ans= Lysosomes are cell organelles found in eukaryotic cells. . They are also called as suicidal bags. They contains digestive enzymes and lysozymes which breaks down the waste material and foreign particles.

(C)

Ans= Adenosine 5'-triphosphate, (ATP) is the principal molecule for storing and transferring energy in cells. It is often referred to as the energy currency of the cell and can be compared to storing money in a bank

(D)

Ans=

1. Bacterial cells ar organism cells that lack a correct nucleus, and different membrane certain organelles. Whereas, Associate in Onion peel cell is Associate in cell that includes a well developed nucleus, and membrane certain organelles.

2. Microorganisms cells have 70S ribosomal units Associate an Onion peel cell has 80S ribosomal units. microorganism cells don't have a cytomembrane; all plant cells have a cell wall.
