Weekly Quiz Competition

Question 1
1 / -0

A smaller spherical body in the nucleus is called the

A
Nucleolus

B
Nucleoluse

C
Nucleolise

D
Nucleoluso

Solution

Nucleolus is the small spherical body seen within the nucleus.
Hence the correct option is A.
Question 2
1 / -0

Animal cells do not have:

A
Cell wall

B
Chloroplast

C
Plastids

D
All of the above

Solution

Animal cells do not have a cell wall. Animal cells do not have chloroplasts. The plastid is a major double-membrane organelle found, among others in the cells of plants and algae. These plastids are not present in animal cells.
Hence the correct option is D.
Question 3
1 / -0

Which of the following cell organelles is present in the cytoplasm?

A
Golgi apparatus

B
Endoplasmic reticulum

C
Chloroplasts

D
All of the above

Solution

The cytoplasm comprises cytosol and the organelles. Organelles are usually membrane-bound structures inside the cell that have specific functions. Some major organelles that are suspended in the cytosol are the mitochondria, endoplasmic reticulum, Golgi apparatus, vacuoles, lysosomes, and in plant cells, chloroplasts.
Hence, the correct option is D.
Question 4
1 / -0

Mark the correct option

A
Every living organism is made up of cells and organs

B
Living organisms have capacity to divide

C
Both A and B

D
None of these

Solution

Living organisations have capacity to reproduce for ex animals give both to young ones of their kind, either directly or through egg.
Question 5
1 / -0

One millionth of a metre is

A
Millimetre

B
Micrometre

C
Nanometre

D
Centimetre

Solution

A micrometre is also known as a micron. It is an SI derived unit of length. Its value is 1×10$$^{−6}$$ metres or one millionth of a metre. Thus the correct answer is option B.
Question 6
1 / -0

A collection of cells joined together in a structural unit to perform a function is known as:

A
Organ

B
Cell

C
Tissue

D
Organ system

Solution

An organ is a group of tissues in a living organism that perform a specific function.
In higher animals, organs are grouped into organ systems.
The tissue is the group of the cell from the common origin and performs a specific function.
The cell is the smallest unit of life that performs all functions.
Hence, the correct option is C.
Question 7
1 / -0

What is a cytoplasm?

A
Irregularly shaped region within the cell that contains genetic material

B
Storage bubbles found in cells

C
Fluid content inside the plasma membrane

D
Fluid inside the nucleus

Solution

The cytoplasm is the jelly-like fluid found between the nucleus and plasma membrane. It is mainly composed of water, salts and proteins. The cytoplasm contains cell organelles like mitochondria, vacuoles, ribosomes, etc.
Hence, the correct option is C.
Question 8
1 / -0

Which of the following combinations are present in plant cell but not in animal cell?

A
Cell wall and plastid

B
Cell wall and cell membrane

C
Plastid and nucleus

D
Cell membrane and cytoplasm

Solution

Plant and animal cells are both eukaryotic cell but have several differences- animal cells are round and do not have a cell wall and plastids but plant cells are rectangular and possess cell wall and plastids.
Cell membrane and cytoplasm are seen in both plant and animal cells.
Hence the correct option is A.
Question 9
1 / -0

A cell without organized nucleus is called as

A
Prokaryotic cell

B
Eukaryotic cell

C
Both A and B

D
None of the above

Solution

Cells without a proper nucleus, are called as prokaryotic cells. Prokaryotes are bacteria which lack membrane-bound organelles and nucleus.
Eukaryotes have a well defined nucleus.
So, the correct answer is option A.
Question 10
1 / -0

The transmission of hereditary characteristics is carried out by ___________.

A
Nucleus

B
Endoplasmic reticulum

C
Ribosome

D
Golgi apparatus

E
Lysosome

Solution

A nucleus is a membrane-bound organelle that contains the cell's chromosome. contains the genetic material responsible for hereditary. A chromosome is a long DNA molecule with the genetic information of an organism. Thus, the nucleus is responsible for carrying and transferring hereditary characteristics.
Hence, the correct option is A.
