Question 8 of 20

9. Which statement is false with respect to multi-cellular organisms?

  Multicellular organisms show division of labour.

 In multi-cellular organisms, groups of cells perform specific roles.

 Different groups of cells are inter-dependent on each other for their continued existence.

 Cytoplasm

 DNA

 Genetic material

 Chromosomes

Question 10 of 20

11. Prokaryotic cells do not have:

 Lysosomes

 Nucleoid

 Plasma membrane

 Ribosome

Question 11 of 20

12. How does protoplasm differ from cytoplasm?

 Protoplasm is same as cytoplasm

 Protoplasm includes nucleus and cytoplasm.

 Protoplasm is a part of cytoplasm

  Cytoplasm and protoplasm are parts of nucleus.

Question 12 of 20

13. Prokaryotic cell contains:

 Two chromosomes

 Three chromosomes

  Single chromosome

 Variable number of chromosomes

Question 13 of 20

14. The presence of various cell organelles within the cell helps in

 Larger size of the cell

 Decoration of the cell

 Crowding of the cell

 Division of labour

Question 14 of 20

15. Cell wall is mainly made up of

 Maltose

 Cellulose

 Sucrose

 Fructose

Question 15 of 20

16. Which of the following statement is false regarding cytoplasm?

 It stains lightly

  It is the fluid content inside plasma membrane.

  It is surrounded by nuclear membrane.

 It contains many cell organelles.

Question 16 of 20

17. This is a generalized structure of:

 Multicellular, eukaryotic organism

 Unicellular, prokaryotic organism.

 Unicellular, eukaryotic organism

 None of these

Question 17 of 20

18. Prokaryotes do not show

 Mitochondria

 Nucleoid

 Cytoplasm

 Cell membrane

Question 18 of 20

19. How is nucleoid different from nucleus?

 Nucleoid is not covered by a membrane, whereas nucleus is membrane bound.

 Nucleoid is present in eukaryotes whereas nucleus is present in prokaryotes.

 Nucleoid does not show genetic material, which is present in nucleus.

 Nucleoid is the other name of nucleus.

Question 19 of 20

20. Which statement is false with respect to eukaryotes?

 They have higher complexity than prokaryotes.

  They have nucleus.

 Membrane bound organelles are present.

 Ribosomes are absent.
