Cell Structure and Cytology

A collection of flashcards covering key concepts from the lecture on cell structure and cytology.

What is Cytology?

The science of studying the cell.

What invention allowed for the advancement of Cytology?

The compound/light microscope.

What is the size range of Prokaryotic cells?

0.1-10 μm.

What are Eukaryotic cells known for?

Having a true nucleus and membrane-bound organelles.

What are the main components of a plant cell identified in the notes?

Cell wall, large central vacuole, chloroplasts.

What is the function of the nucleus?

Acts as the control center for the cell and stores DNA.

What is the difference between Rough and Smooth Endoplasmic Reticulum?

Rough E.R. is studded with ribosomes and synthesizes proteins; Smooth E.R. lacks ribosomes and is involved in lipid synthesis and detoxification.

What are micrometers and nanometers used to measure?

Micrometers are used to measure cell structures, and there are 1000 nanometers in one micrometer.

Why are cells limited in their size?

As cells grow, their volume increases faster than surface area, making it difficult to maintain proper function.

What is the primary structure of the plasma membrane?

A double layer of phospholipids.
