Solution

The answer is a. True.

Here are the steps to understand why:

  1. Definition: Cells are the smallest unit of life that can replicate independently, and they are often called the "building blocks of life".

  2. Structure: Each cell contains all the necessary parts to perform its functions, including a nucleus (in eukaryotic cells), cytoplasm, and various organelles.

  3. Function: Cells carry out all the functions necessary for life, including taking in nutrients, converting those nutrients into energy, carrying out specialized functions, and reproducing.

  4. Universality: All living organisms, from the simplest bacteria to the most complex plants and animals, are made up of one or more cells. This is known as the Cell Theory, one of the fundamental principles of biology.

Therefore, it is true that the basic structural and functional units in all living organisms are known as cells.
