Which of the following best explains why cells are generally small?
Small cells are faster at moving through the body
Small cells have a higher surface area-to-volume ratio, allowing more efficient nutrient and waste exchange
Small cells are easier for organisms to see under a microscope
Small cells always contain more mitochondria
If a cell grows too large, which problem is most likely to occur?
It will divide immediately
Nutrients and wastes cannot move in and out efficiently
It will gain more ribosomes than needed
Its DNA will disappear
Select all the ways that a high surface area-to-volume ratio benefits a cell:
Faster transport of nutrients into the cell
Faster removal of waste products
Easier movement of the cell through blood
More efficient energy production in mitochondria
A glucose molecule reaches mitochondria faster in a (a) cell because the distance it must travel is shorter.
Which of the following cells would likely need the most mitochondria?
A small cube-shaped cell
A large cube-shaped cell
A small cylinder-shaped cell
A tiny spherical cell
When a cube-shaped cell doubles in length, what happens to its surface area-to-volume ratio?
It stays the same
It increases
It decreases
It becomes zero
A cell has a surface area of 24 cm² and a volume of 8 cm³. Its surface area-to-volume ratio is (a) .
Which cell shape is most efficient for maximizing surface area relative to volume?
Cube
Sphere
Cylinder
Why do some specialized cells, like nerve or muscle cells, need to be larger than typical cells? Select all that apply:
They must transport materials across long distances
They perform specialized functions requiring more internal structures
They always need more DNA
They divide less frequently
Which of the following best explains why bigger is not always better for a cell?
Bigger cells are always unhealthy
Bigger cells have a lower surface area-to-volume ratio, making nutrient and waste exchange less efficient
Bigger cells contain fewer ribosomes
Bigger cells always die
If two cells have the same surface area but different volumes, which cell is more efficient at exchanging nutrients and waste?
The smaller volume cell
The larger volume cell
Both are equally efficient
Efficiency depends on mitochondria only
Which of the following best predicts when a cell will divide?
When it gets too large to maintain an efficient surface area-to-volume ratio
When it has enough mitochondria
When it has too many ribosomes
When the organism grows taller
Which of the following statements is true about the shape of specialized cells?
All specialized cells are spherical
Long or thin shapes increase surface area for transport and communication
Only cube shapes are efficient
Shape does not affect cell function
In Model 2, which trend is observed as the diameter of the shapes increases?
Surface area increases faster than volume
Volume increases faster than surface area
Surface area and volume increase at the same rate
Surface area decreases while volume increases
A hypothetical cell shaped like a thin cylinder would be advantageous because:
It has more DNA than a cube-shaped cell
It increases surface area relative to volume, improving nutrient and waste exchange
It grows faster than a spherical cell
It divides less frequently
