NEET Biology question
The factors which set the limit of cell size or volume are I. nucleo-cytoplasmic or kern-plasma ratio II. rate of metabolic activity III. ability of oxygen and other materials to reach every part of the cell IV. ability of waste products to pass to the outside V. ratio of surface area to the volume of the cell Identify the correct set of statements
Answer: (D)
Solution
Cell size is constrained by the need to maintain an adequate nucleo-cytoplasmic ratio (I), sustain metabolic activity (II), ensure oxygen/nutrient diffusion to all parts of the cell (III), and allow efficient waste removal (IV); all of
