Question

Identify the statement which is true for cells.

• A. Cells can be easily seen with naked eyes.
• B. An 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 are 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. Multicellular creatures use a variety of cells to perform their many duties, in contrast to unicellular organisms, which consist of just one cell that performs all of the processes required by the organism.
2. In unicellular creatures, you can find yeast, protists, and bacteria.

Explanation for the incorrect options:

Option A:

1. The majority of cells are invisible to the human eye since most organisms are unicellular.
2. The majority of the cells are very small.
3. The majority of cells lack a nucleus.
4. The bird's egg is a cell that can be seen with the unaided eye, whereas bacterial cells must be viewed under a microscope.

Option B:

1. Since the fertilized egg lacks a cell wall, it is technically not a cell.
2. Insect eggs are enormous, very complex cells protected by a shell that is incredibly hard.
3. Anteroposterior and ventrodorsal polarity is expressed by the egg cell and its surrounding eggshell.
4. A single-celled, haploid ovum is present in the egg before fertilization, or you could say when it is unfertilized.

Option D:

1. The general rule for cells is that structure determines function.
2. Throughout the body, several cells serve various purposes.
3. Different forms are required for them to carry out various roles.
4. Although they all share the same DNA, depending on where they reside in the body, different blueprints are activated.
5. Multicellular creatures use a variety of cells to perform their many duties, in contrast to unicellular organisms, which consist of just one cell that performs all of the processes required by the organism.

Final answer: A single cell can perform all the functions in a unicellular organism is the correct statement.
