All Flashcards
What is the effect of a cell growing larger?
Volume increases faster than surface area, reducing SA/V ratio.
What is the effect of a low SA/V ratio?
Reduced efficiency in nutrient uptake and waste removal, potentially limiting cell function.
What is the effect of having more surface area in a cell?
Allows for more transport of materials into and out of the cell.
What is the effect of having smaller volume in a cell?
Means less distance for materials to travel within the cell.
What happens when a cell cannot efficiently exchange nutrients and waste?
Cellular function is compromised, potentially leading to cell death.
Define surface area in the context of cell size.
The 'skin' of the cell where nutrient entry and waste exit occur.
Define volume in the context of cell size.
The space inside the cell where all cellular processes happen.
Define surface area to volume ratio (SA/V).
The ratio of a cell's surface area to its volume; a key factor in determining cell efficiency.
What is the significance of a high SA/V ratio?
Indicates a more efficient cell, allowing for better nutrient uptake and waste removal.
Why is maximizing nutrient and waste exchange important for cells?
Essential for maintaining cell function and survival.
