Question

The given figure shows a typical animal cell with its parts being labelled as a - j. Identify the labelled parts and select the incorrect option regarding it.

• A. The organelles e, h, g and i are membrane-bound organelles which function in close co-ordination with one another.
• B. f organelle is responsible for the synthesis of fats inside the cells and it stores Ca${}^{2+}$ for release during muscle contraction.
• C. a and b have selective permeability, i.e., they allow only selected substances to pass inwardly.
• D. j is the site for protein synthesis. It allows hereditary message from d to get translated into proteins.

Answer 1

The correct option is B f organelle is responsible for the synthesis of fats inside the cells and it stores Ca${}^{2+}$ for release during muscle contraction.

The mitochondria is represented by the f. Mitochondria is the oval shaped double membrane bound organelle. The outer membrane is smooth and inner membrane is folded to form cristae. It is also known as the powerhouses of the cell because it produces and stores energy in the form of ATP. In muscle cells, it produces fats and stores Ca${}^{2+}$ that involves in the muscle contraction.
