A Microbiologist Has Discovered What She Thinks Are Two New

question 32

Essay

A microbiologist has discovered what she thinks are two new types of photosynthetic cells.The first cell (organism 1)appears nearly cubic and is approximately 1.5 ?m wide × 1.5 ?m long × 1.5 ?m deep.The second,larger cell (organism 2)is 5 ?m wide × 15 ?m long × 2 ?m deep.
a.What is the surface area/volume ratio of each organism?
b.Based on what you know about the surface area/volume ratios,which organism will find it more difficult to interact with the surrounding environment?
c.Suggest possible strategies that might allow the organism identified it part (b)to cope with its reduced capacity to interact with the environment.
d.Which of these organisms is more likely to be a prokaryote?

Definitions:

Dendrites

Extensions of neurons that receive signals from other neurons or sensory receptors, playing a key role in the communication within the brain.

Axons

Long, slender projections of nerve cells that transmit electrical impulses away from the neuron's cell body.

Somas

The cell bodies of neurons, containing the nucleus and cytoplasm, which are essential for the neuron's function and health.

Terminal Buttons

Terminal buttons are the small nodules at the end of axons that release chemical neurotransmitters, which facilitate the transmission of signals from one neuron to another.
