Explanation / Answer

1. Option b is correct. Prokaryotes lack well defined nucleus, golgi apparatus, DNA, Endoplasmic reticulum etc.

2.option b is correct. As well as prokaryotes are devoid of well defined nucleus and lysosome.

3. Option c is correct .

The three tenets to the cell theory are as described below:

1.All living organisms are composed of one or more cells.
2.The cell is the basic unit of structure and organization in organisms.
3.Cells arise from pre-existing cells.

Que 4.option b is correct. Peroxisomes contain an enzyme called catalase for toxic hydrogen peroxide.

5.option a is correct. Both the cells consist of cytoplasm in which organelles are present .the main difference is the presence of complex structures of organelle in eukaryotic cell

6. False. Cytosol is a part of cytoplasm in which no organelle is included whereas cytoplasm consist of cytosol ,organelles

7.option c. Mitochondria is double membrane structure in which inner membrane is folded into finger like projections .it is the powerhouse of the cell

8.false. nucleolus is present inside the nucleus which controls activities of nucleus. Nucleus is covered by nuclear membrane

9.option a. Lipid synthesis occurs in smooth endoplasmic reticulum and protein synthesis in rough ER

10.option b . Peroxiomes break down hydrogen peroxide by enzyme called catalase
