What is a colorless, jelly like substance found inside cells in which food elements such as proteins, fats, carbohydrates, mineral salts and water are present?

  1. Protoplasm

  2. Cytoplasm

  3. Nucleus

  4. Centrioles

The correct answer is: Protoplasm

Protoplasm is the correct answer because it refers to the colorless, jelly-like substance found inside cells where various food elements such as proteins, fats, carbohydrates, mineral salts, and water are present. This is the living substance of the cell where all cellular activities take place. The other options are incorrect: - Cytoplasm is the substance contained within the cell membrane, not specifically where food elements are found. - The nucleus is the control center of the cell and contains genetic material, not food elements. - Centrioles are organelles involved in cell division, not the site where food elements are stored.
