Question

Choose the correct answer from the four options given below.

The cell component visible only during cell division:

• A. Mitochondria.
• B. Chloroplast.
• C. Chromosomes.
• D. Chromatin.

Answer 1

The correct option is C

Chromosomes.

The correct option is C:

Explanation of the correct option

1. Chromosomes are thread-like structures found within the nucleus of both animal and plant cells.
2. Protein and a single molecule of deoxyribonucleic acid (DNA) make up each chromosome.
3. DNA is passed along from parents to children and carries the precise instructions that distinguish each living thing.

Explanation of the incorrect options

Option A:

1. Mitochondria are membrane-bound cell organelles that provide the majority of the chemical energy required to power the cell's metabolic activities.
2. Adenosine triphosphate is a tiny molecule that stores the chemical energy created by mitochondria (ATP).
   

Option B:

1. A chloroplast is a type of organelle found in the cells of plants and algae.
2. Chloroplast is responsible for photosynthesis, or the conversion of solar energy into chemical energy for growth.

Option D:

1. Chromatin is a DNA and protein complex that creates chromosomes in eukaryotic cells' nuclei.
2. Nuclear DNA is not found in free strands; instead, it is highly condensed and wrapped around nuclear proteins to fit inside the nucleus.

The cell component visible only during cell division are Chromosomes.
