Solution
-
The term "cellular differentiation" refers to (B). The transformation of stem cells into specialized cells. This process allows a cell to develop more specialized functions by expressing the genes needed for these functions.
-
The cell organelle involved in the synthesis of proteins is (C). Ribosomes. Ribosomes are the sites in a cell where protein synthesis takes place.
-
The function of the Golgi Apparatus in the cell is (C). Packaging and modification of proteins. The Golgi apparatus modifies, sorts, and packages proteins and lipids for transport to their final destinations.
-
The structure that controls the movement of substances in and out of the cell is (B). Cell membrane. The cell membrane is a selective barrier that allows certain molecules to pass through while keeping others out.
-
The cell organelle that contains its own genetic material and is involved in energy production is (A). Mitochondria. Mitochondria are known as the powerhouses of the cell because they generate most of the cell's supply of adenosine triphosphate (ATP), used as a source of chemical energy.
-
The organelle that primarily aids in maintaining cell turgidity in plant cells is (C). Vacuole. Vacuoles in plant cells store water and maintain turgor pressure against the cell wall.
