Quick Flashcard-Cell Structure & Function

Front

What are the primary functions of lipids in a cell?

Back

Lipids are used to build cell membranes, store extra energy, provide protection, and insulation for the organism.

Front

Who were the key contributors to cell theory besides Leeuwenhoek and Hooke?

Back

Matthias Schleiden, Theodore Schwann, and Rudolph Virchow.

Front

What common characteristics do all cells (prokaryotic and eukaryotic) share?

Back

All cells have cell membranes, cytoplasm, DNA, and ribosomes.

Front

What is the function of the nucleus in a cell?

Back

The nucleus protects the DNA, which holds instructions for making proteins and cellular processes.

Front

What is the role of the rough endoplasmic reticulum (ER) in a cell?

Back

The rough ER makes protein-based products that will be secreted.

Front

What is the structure and function of a cell membrane?

Back

The cell membrane is a lipid bilayer that protects the cell and regulates what enters and exits.

Front

What is the significance of ribosomes in cellular function?

Back

Ribosomes are responsible for protein synthesis in the cell.

Front

How do prokaryotic cells differ from eukaryotic cells?

Back

Prokaryotic cells lack a nucleus and membrane-bound organelles, while eukaryotic cells have both.

Front

What is the role of cytoplasm in a cell?

Back

Cytoplasm is the gel-like substance that fills the cell and contains organelles.

Front

What is the function of the cell wall in plant cells?

Back

The cell wall provides structure and support to plant cells.
