Flashcards

Why are most cells small?

To maintain a high surface area-to-volume ratio, facilitating efficient material exchange with the environment.

Microscopy's capability?

Light and electron microscopy enables the visualization of small cellular structures enhancing our understanding of cell biology.

What do all living things have?

All living things have DNA and RNA, the blueprint and messenger for genetic information.

Shared cell feature?

Eukaryotic and prokaryotic cells both have a cell membrane, which serves as a barrier and regulator for cell interactions.
