Cell Biology Review

Flashcards for Biology, Chemistry, and Physics review, focusing on cell biology.

Prokaryotic Cells

Cells lacking a nucleus or other membrane-bound organelles.

Eukaryotic Cells

Cells containing a nucleus and other membrane-bound organelles.

Organelles

Structures within a cell that perform specific functions.

Nucleus

Control center of the cell, containing the nucleolus and chromatids.

Nucleolus

Site of ribosome production within the nucleus.

Chromatids

Long strands of DNA in the nucleus that condense into chromosomes during cell replication.

Endoplasmic Reticulum (ER)

Network of membranes involved in protein and lipid synthesis.

Rough ER

ER covered in ribosomes, giving it a rugged appearance and aiding in protein synthesis.

Smooth ER

ER with enzymes, proteins, and lipids used in different areas of the cell.

Golgi Body

Organelle that packages proteins.

Lysosomes

Organelles found in animal cells that release their contents outside the cell.

Mitochondria

Powerhouse of the cell, converting glucose into ATP.

Centrioles

Organelles found only in animal cells, made of microtubules, and help in cell division.

Microtubules

Thick protein tubes that make up centrioles and help in cell division.
