Lesson 7: Surface Area to Volume Ratio Flashcards
(7 cards)
1
Q
What is a cell’s purpose when it passes through a cell membrane and diffuses through the cell?
A
- Can be used to create important molecules and structures
- Can prove nucleus with information about surrounding environment
2
Q
Why is it harmful for a cell to be bigger in size?
A
- More molecules will need to be used by cell to carry out functions
- Distance molecules have to travel will increase
3
Q
What does the surface area reflect in a cell?
A
- Reflects the area cells have to move in/out of the cell
4
Q
What does the volume reflect in the cell?
A
- Reflects how far particles must move inside a cell
5
Q
What is the desired surface area to volume ratio?
A
- Want a large surface area and a small volume
6
Q
Important Law
A
- As cell size increases, surface area to volume ratio decreases
7
Q
Do flatter cells have a higher or lower surface area to volume ratio?
A
- Higher
