Weekly Quiz Competition

Question 1
1 / -0

Mitochondria are semi-autonomous due to

A
Presence of functional naked DNA

B
Presence of ribosomes

C
It can not divide

D
All of the above

Solution

Mitochondria contain self-replicating DNA as well as ribosomes and are able to synthesise some of its own proteins. But, since they depend on nuclear gene for biogenesis and on ground cytoplasm for biosynthetic activities, they cannot exist independently. Hence, they are called as semi-autonomous organelles.
Question 2
1 / -0

Which part of the cell controls all activities of the cell?

A
Nucleus

B
Lysosome

C
Peroxisome

D
Cell membrane
Question 3
1 / -0

Which one of the following is present in bacteria?

A
Nucleus

B
Golgi apparatus

C
Mitochondria

D
Ribosomes

Solution

Bacteria belong to group Monera. Organisms belonging to group Monera are primitive, unicellular and prokaryotes. They do not possess many membrane bound organelles such as mitochondria, Golgi apparatus, etc. They also do not have well defined membrane bound nucleus. They possess protein synthesis machinery, i.e., ribosomes. Ribosomes are non-membranous. Bacterial ribosome is of 70s type.
Question 4
1 / -0

Correct statement regarding Vacuoles is?

A
It is non-living inclusion found in the cytoplasm

B
It is filled with water and other organic substances

C
It is large in plant cell

D
All of the above
Solution
- Vacuoles are non-living inclusion in the cytoplasm bound by a membrane.
- These are filled with water and other organic substances in solution form called cell sap.
- In plants, it is large in size and animals, it is smaller in size.
Thus, Option D is correct.
Question 5
1 / -0

Cellular organelle also known as suicidal bag is formed from which among the following structure:-

A
Lysosome

B
Golgi bodies

C
Mitochondria

D
Endoplasmic reticulum
Question 6
1 / -0

What do prokaryotes do not possess?

A
True nucleus

B
Membrane bound organelles

C
Ribosome

D
Both A and B
Question 7
1 / -0

The nucleus is separated from surrounding cytoplasm by a nuclear envelope which is

A
Single and porous

B
Double and porous

C
Single and non-porous

D
Double and non-porous
Solution
- A nuclear membrane, also known as the nuclear envelope, is a double lipid bilayer membrane, which surrounds the nucleus containing genetic material and nucleolus in eukaryotic cells.
- The nuclear membrane consists of two lipid bilayers- the inner nuclear membrane and the outer nuclear membrane and consists of pores called nuclear pores for the transportation of DNA, RNA, and proteins.
Thus, the correct answer is option B.
Question 8
1 / -0

What is the appropriate difference between plant cells and animal cells?

A
Plant cell- cell wall is present, Animal cell- cell wall is absent

B
Plant cell- cell wall is absent, Animal cell- cell wall is present

C
Plant cell- cell wall is present, Animal cell- cell wall is present

D
Plant cell- cell wall is absent, Animal cell- cell wall is absent

Solution

Plant cell possesses a cell wall while animal cells lack. Plant cells possess chloroplasts while animal cells lack. Plant cells possess single, large vacuole while animal cells possess many, small vacuoles. Thus, the correct answer is option A.
Question 9
1 / -0

Nucleus of a cell

A
Contains ribosomes

B
Contains the genetic material

C
Contains Golgi body

D
All of the above

Solution

The nucleus controls the functioning of a cell. It is generally located in the center of the cell and is spherical in shape. It has a double-walled membrane which separates it from the cytoplasm. It contains the genetic material DNA and RNA in it. This porous membrane allows the transfer of material in the nucleus and cytoplasm. The nucleus contains chromosomes, which in turn has the genetic material.
Hence the correct option is B.
Question 10
1 / -0

Lysosomes are the reservoirs of

A
Fats

B
RNA

C
Secretory glycoproteins

D
Hydrolytic enzymes

Solution

A lysosome is a single membrane-bound cell organelle which consists hydrolytic enzymes that digest cell debris, foreign particles, dead or nonfunctional organelles. It can also digest the waste produced by the cellular activities
So, the correct answer is 'Hydrolytic enzymes'
