Multiple Choice
Why is it advantageous for cells to be small?
A
Smaller cells can contain more organelles, increasing their functionality.
B
Smaller cells can divide more slowly, conserving energy.
C
Smaller cells are less likely to be affected by environmental changes.
D
Smaller cells have a higher surface area-to-volume ratio, which facilitates efficient nutrient uptake and waste removal.
Verified step by step guidance
1
Understand the concept of surface area-to-volume ratio: As a cell decreases in size, its surface area-to-volume ratio increases. This means that for a given volume, a smaller cell has more surface area available relative to its volume.
Recognize the importance of surface area: The cell membrane, which is the surface area of the cell, is responsible for the exchange of materials such as nutrients and waste products with the environment.
Consider the efficiency of nutrient uptake and waste removal: A higher surface area-to-volume ratio allows for more efficient diffusion of substances into and out of the cell, as there is more membrane surface available for exchange relative to the cell's volume.
Relate this to cell functionality: Efficient nutrient uptake and waste removal are crucial for maintaining cellular functions and supporting metabolic processes, which is why smaller cells with higher surface area-to-volume ratios are advantageous.
Conclude with the biological significance: The increased efficiency in material exchange supports the cell's survival and function, making smaller cells more adaptable and efficient in their environments.
