Concept explainers
(a)
Interpretation: To identify whether the statement “ribosomes are organelles” concerning the components present in a eukaryotic cell is true or false.
Concept introduction: In eukaryotic cells, the water-based material which is present between the nucleus and cell membrane of a cell is known as cytoplasm. The various small structures are present in the cytoplasm which perform a particular function of the cell and are known as organelles. The three important organelles present in the cell are ribosomes, lysosomes, and mitochondria.
(b)
Interpretation: To identify whether the statement “lysosomes are found in the cytoplasm of a cell” concerning the components present in a eukaryotic cell is true or false.

(c)
Interpretation: To identify whether the statement “the terms cytoplasm and cytosol have the same meaning” concerning the components present in a eukaryotic cell is true or false.
