Sagot :
Answer:
A.
The correct answer would be A. ratio of surface area to volume .The cells are mostly spherical in shape.The surface area of the sphere = 4πr²The volume of the sphere = (4πr³)/3Thus, the increase in size would increase the volume (r³) more as compared to the increase in surface area (r²).The ratio of surface area to volume would decrease due to which the diffusion rate would not be efficient enough to distribute the essential elements throughout the volume of the cell.
Explanation:
Ratio of the surface area to volume.
Answer:
A
Explanation:
The answer options (factors) that are capable of limiting a cell size include the following:
A. ratio of surface area to volume.
B. rate of moving materials across the cell's membrane.
C. efficiency of using the information in a cell's DNA.
A cell can be defined as the fundamental (basic) functional, structural and smallest unit of life, which is mainly found in all living organisms.
Some of the factors that limit the size of a living cell include the following:
The ratio of surface area to volume: this is always required to be small, so as to allow sufficient materials such as food, move through the cell membrane quickly for the cell's survival.
The rate of moving materials across the cell's membrane: the survival of a cell is highly dependent on the rate at which necessary materials move across it's cell membrane.
The efficiency of using the information in a cell's DNA: a small sized cell has higher efficiency in the use of information that are stored in its deoxyribonucleic acid (DNA).
