Question

1. according to the cell theory, which of the following best describes the role of cells in living organisms?

a cells are the basic building blocks of all living organisms.
b cells make up the tissues that are present in all forms of life.
c cells are produced spontaneously when living organisms need them.
d cells contain the same specialized organelles required for life in both prokaryotic and eukaryotic organisms.

Explanation:

Cell theory states that all living things are made of cells, and cells are the basic unit of structure and function in living organisms. Option A aligns with this as it says cells are the basic building blocks of all living organisms. Option B is incorrect as cell theory doesn't focus on tissues in this context. Option C is wrong because cells come from pre - existing cells (not spontaneous generation). Option D is incorrect as prokaryotic cells lack many organelles that eukaryotic cells have (like mitochondria, endoplasmic reticulum etc.).

Answer:

A. Cells are the basic building blocks of all living organisms.
