Weekly Quiz Competition

Question 1
1 / -0

Use the following information to answer the next question.

Multicellular organisms are made of a large number of cells, wherein each cell performs a specific function.

Which of the following organisms is not multicellular?

A
Plants

B
Protists

C
Monkey

D
Mushrooms

Solution

Protists are unicellular organisms. A protist is composed of a single cell.

Hence,the correct answer is option B.

Why alternative A, C and D are wrong:

Plants, monkeys, and mushrooms are multicellular organisms. Hence, alternatives A, C, and D are incorrect.
Question 2
1 / -0

Use the following information to answer the next question.

Chlorophyll plays a major role in plant photosynthesis.

Chlorophyll performs the function of

A
absorbing water in leaves.

B
trapping light energy in leaves.

C
releasing carbon dioxide into the atmosphere.

D
releasing manufactured food into atmosphere.

Solution

Chlorophyll is a pigment that traps solar energy in leaves, which is essential for photosynthesis.The functions mentioned in alternatives A, C, and D are not performed by chlorophyll. Hence, these alternatives are incorrect.

Hence, the correct answer is option B.
Question 3
1 / -0

Use the following information to answer the next question.

Genetic material is present in the cells of all living organisms.

Genetic material does not carry out the function of

A
transmitting hereditary information

B
helping in protein synthesis

C
controlling cellular activities

D
protecting cell organelles

Solution

The genetic material does not play any role in protecting cell organelles. This function is performed by the cell membrane.

The correct answer is D.

Why alternatives A, B and C are wrong:

The functions mentioned in alternatives A, B, and C are performed by genetic material. Hence, these alternatives are incorrect.
Question 4
1 / -0

Use the following information to answer the next question.

Cell membrane has a common function in both plants and animals.

Cell membrane performs the function of

A
controlling the movement of materials in and out of the cell

B
manufacturing energy to carry out various functions

C
controlling the activities of the cell

D
storing food, water, and waste

Solution

The cell membrane regulates the flow of materials in and out of the cell. It allows only specific materials to enter or leave the cell.

The correct answer is A.

Why alternative B is wrong:

Mitochondria produces energy to carry out cellular functions. Hence, this alternative is incorrect.

Why alternative C is wrong:

Nucleus controls the different cellular activities. Hence, this alternative is incorrect.

Why alternative D is wrong:

Vacuoles help in storing food, water, and toxic waste. Hence, this alternative is incorrect.
Question 5
1 / -0

Use the following information to answer the next question.

Lysosomes occur more commonly in animal cells than plant cells.

Lysosomes perform the function of

A
digesting food particles

B
carrying out photosynthesis

C
providing support to the cell

D
synthesizing proteins for the cell

Solution

The lysosomes digest food particles and old worn out organelles in the cell.

The correct answer is A.

Why alternative B is wrong:

Chloroplasts perform photosynthesis in all plant cells.

Why alternative C is wrong:

The cell membrane provides support to the cell.

Why alternative D is wrong:

Ribosomes synthesize proteins inside the cell.
Question 6
1 / -0

Use the following information to answer the next question.

The energy required to sustain life is produced inside the cells of all eukaryotic organisms.

The given function is performed by the

A
vacuole

B
nucleus

C
ribosome

D
mitochondrion

Solution

The mitochondrion is the site of energy production within the cell. Here, sugar molecules are broken down to release energy.

The correct answer is D.

Why alternative A is wrong:

The vacuole stores food, water, and waste produced by the cell.

Why alternative B is wrong:

The nucleus controls all the activities of the cell.

Why alternative Cis wrong:

The ribosome takes part in protein synthesis within the cell.
