Study Notes

Cell Organelles Overview

Vacuoles: Store materials within the cell; provide temporary storage for food, enzymes, and waste products.
Chloroplasts: Found only in plants; contain chlorophyll that traps sunlight energy and gives plants their green color; consist of closely stacked, flattened sacs.
Ribosomes: Sites of protein synthesis; small bumps on portions of the endoplasmic reticulum (ER); essential for cellular functions.
Vesicles: Transport materials within the cell; play a key role in cellular logistics.
Cytoplasm: The region inside the cell excluding the nucleus; the site for many metabolic processes.

Eukaryotic Organelles

Nucleus: Organelle that controls cell functions; houses DNA and manages cellular activities in eukaryotes.
Lysosomes: Digest excess or worn-out cell parts; break down food particles and invading pathogens like viruses or bacteria.
Mitochondria: Produce usable energy for the cell through ATP synthesis; known as the powerhouse of the cell.
Golgi Apparatus: Packages proteins for transport out of the cell; modifies, sorts, and ships cellular products.

Additional Structures

Cell Wall: Firm protective structure in plants, fungi, most bacteria, and some protists; provides shape and support.
Endoplasmic Reticulum (ER): Site where ribosomes are made; involved in protein and lipid synthesis.
Cell Membrane: Surrounds the cell; composed of a phospholipid bilayer that supports and regulates what enters or leaves the cell.
Lipid Bilayer: Provides structural support for the cell; consists of two layers of phospholipids.
Nucleolus: Located within the nucleus; responsible for the assembly of ribosomes and contains a collection of DNA.
Cytoskeleton: Composed of hollow tubes; provides structural support and shape to the cell.
Cilia: Small hair-like structures used for movement or sensing environmental changes.
Flagella: Longer, whip-like structures that facilitate movement in certain cells.
