cell organelles

Cytoplasm

A jelly-like fluid that fills the cell and houses organelles, facilitating chemical reactions and transport processes.

Nucleus

The control center of the cell that contains DNA and regulates gene expression and replication.

Nucleolus

The structure located within the nucleus responsible for ribosome subunit production.

Nuclear Envelope

A double membrane that encapsulates the nucleus and controls the flow of materials in and out.

Ribosomes

Sites of protein synthesis found free in the cytoplasm or attached to the endoplasmic reticulum.

Endoplasmic Reticulum (ER)

A network of membranes involved in protein and lipid synthesis.

Rough ER

Endoplasmic reticulum with ribosomes on its surface, involved in the synthesis of proteins.

Smooth ER

Endoplasmic reticulum that lacks ribosomes on its surface, involved in lipid synthesis and detoxification.

Vesicles

Small membrane-bound sacs that transport materials within the cell.

Golgi Apparatus

Modifies, sorts, and packages proteins and lipids for secretion or use within the cell.

Lysosomes

Contain digestive enzymes to break down waste, cellular debris, and macromolecules.

Vacuole

A storage sac that can hold various substances; larger in plant cells for maintaining turgor pressure.

Mitochondria

Known as the powerhouse of the cell, they generate ATP through cellular respiration.

Chloroplast

Organelles found in plant cells that conduct photosynthesis to convert light energy into chemical energy.

Cell Wall

A rigid outer layer found in plant cells, providing structure and protection.

Cytoskeleton

A network of protein filaments and tubules that provides shape, support, and facilitates movement within the cell.

Centrioles

Cylindrical structures involved in cell division, helping to organize the cytoskeleton during mitosis.
