Question

Identify the statement which is true for cells.

• A. Cells can be easily seen with naked eyes.
• B. Insect’s egg is not a cell.
• C. A single cell can perform all the functions in a unicellular organism.
• D. The size and shape of cells is uniform in multicellular organisms

Answer 1

The correct option is C

A single cell can perform all the functions in a unicellular organism.

The correct option is C.

Explanation for the correct option:

1. Cells are referred to as the structural and functional unit of life since all living species are made up of cells, and cells execute all tasks that occur within the bodies of animals.
2. The unicellular organism is composed of a single cell that accomplishes all of the biological activities required for existence.

Explanation for the incorrect options:

Option A:

1. Because cells are so little, the bulk of them cannot be seen with our naked eyes.
2. Microscopes are made up of a series of lenses that magnify a picture.

Option B:

1. Each insect species produces eggs that are both genetically and visually different – spherical, ovate, conical, sausage-shaped, barrel-shaped, or torpedo-shaped.
2. Regardless of size or shape, each egg contains only one live cell – the female gamete.

Option D:

1. Different cells in the body serve various activities.
2. They require varied forms to carry out their duties.
3. They all have the same DNA, but depending on where they are in the body, various blueprints are triggered.

Final answer: The statement which is true for cells is a single cell can perform all the functions in a unicellular organism.
