Eukaryotic Cell Anatomy

Vocabulary flashcards covering cellular organelles and structures labeled in the cell diagram.

Diagram of Cell Structures

An anatomical illustration displaying the organelle arrangement and internal components of a eukaryotic cell.

Nucleus

The core membrane-bound cellular organelle that encloses the nucleolus, nuclear envelope, and nuclear pores.

Nucleolus

A prominent structure situated inside the nucleus of the cell.

Nuclear Envelope

The double membrane surrounding the cell nucleus.

Nuclear Pore

A microscopic opening in the nuclear envelope that facilitates transport into and out of the nucleus.

Plasma Membrane

The outer phospholipid barrier enclosing the cytoplasm and cellular contents.

Cytoplasm

The fluid substance and matrix surrounding the cellular organelles inside the plasma membrane.

Rough Endoplasmic Reticulum

A membrane network studded with ribosomes involved in cellular protein synthesis and processing.

Smooth Endoplasmic Reticulum

A membrane network contiguous with the rough endoplasmic reticulum that lacks ribosomes.

Golgi Complex

An organelle involved in modifying, sorting, and packaging proteins and lipids.

Mitochondrion

An organelle responsible for cellular energy production.

Ribosome

A small cellular structure that synthesizes proteins, found free in the cytoplasm or attached to the rough endoplasmic reticulum.

Lysosome

A membrane-bound sac involved in cellular breakdown, waste management, and digestion.

Peroxisome

A specialized organelle that performs metabolic oxidation and detoxification reactions.

Centrosome

A structure located near the cell center that acts as a microtubule organizing center.

Microtubule

A tubular component of the cytoskeleton involved in cell structure and internal transport.

Microfilament

A thin filament component of the cytoskeleton assisting in structural support and cellular motion.

Flagellum

A long tail-like appendage extending from the cell membrane used for cellular locomotion.

Cilia

Short, hair-like projections extending from the cell surface involved in movement or sensing.
