Fundamentals of Cell Biology Quiz

Mitochondria produce energy in the form of ATP through cellular respiration.

The cell membrane regulates the passage of substances, maintaining cellular homeostasis.

Lipids, particularly phospholipids, form the basic structure of cell membranes.

Chloroplasts contain chlorophyll and are where photosynthesis occurs in plant cells.

Mitochondria contain their own DNA and are the sites of cellular respiration, producing ATP.

DNA (deoxyribonucleic acid) carries the genetic instructions necessary for cellular function and inheritance.

Lysosomes contain enzymes for breaking down waste materials and cellular debris.

Osmosis is the movement of water molecules across a semipermeable membrane, not a type of cell division.

Ribosomes are the cellular machinery responsible for synthesizing proteins.

The Golgi apparatus processes, modifies, and packages proteins for secretion or use within the cell.

Lysosomes contain digestive enzymes that break down waste materials and cellular debris.

Lysosomes are not components of the nucleus; they are membrane-bound organelles responsible for digestion.

The rough endoplasmic reticulum is studded with ribosomes and involved in protein synthesis and processing.

Centrioles play a key role in organizing the spindle fibers during cell division.

Robert Hooke is credited with proposing the cell theory after observing cork cells.

The cytoskeleton provides structural support and facilitates cellular movement and shape.

Peroxisomes are involved in detoxifying harmful substances in the cell.
