|
Cell Membrane
|
Biological membrane seperating the interior of the cell from the outside environment.
|
|
|
Cytosol
|
Viscous, semitransparent fluid substance of cytoplasm in which other elements are suspended.
|
|
|
Cytoskeleton
|
Skeleton of the cell. An elaborate series of rods running through the cystol, supporting cellular structures and providing the machinery to generate various cell movements.
|
|
|
Microvilli
|
Tiny projections on the free surfaces of some epithelial cells; increase surface area for absorption.
|
|
|
Cilia
|
Tiny, hairlike projections on cell surfaces that move in a wavelike manner.
|
|
|
Centrosome
|
Contains centriole
|
|
|
Centriole
|
Important for cell division
|
|
|
Ribosome
|
Cytoplasmic organelles at which proteins are synthesized
|
|
|
Mitrochondria
|
Cytoplasmic organelles responsible for ATP generation for cellular activities
|
|
|
Endoplasmic Reticulum
|
Membranous network of tubular or saclike channels in the cytoplasm of a cell
|
|
|
Rough Endoplasmic Reticulum
|
Studded with protein-manufacturing ribosomes
|
|
|
Smooth Endoplasmic Reticulum
|
Many metabolic processes
|
|
|
Golgi Apparatus
|
Membranous system close to the cell nucleus that packages protein secretions for export, packages enzymes into lysosomes for cellular use, and modifies proteins destined to become part of a cellular membrane.
|
|
|
Lysosome
|
Organelles that originate from the Golgi Apparatus and contain strong digestive enzymes.
|
|
|
Peroxisomes
|
Membranous sacs in the cytoplasm containing powerful oxidase enzymes that use molecular oxygen to detoxify harmful or toxic substances, such as free radicals.
|
|
|
Nucleus
|
Control center of a cell; contains genetic material.
|
|
|
Nucleus:
Nuclear pore |
Complex proteins line each pore forming an aqueous transport channel and regulating entry and exit of large particles in and out of the nucleus.
|
|
|
Nucleus:
Nuclear envelope |
Double membrane barrier separated by a fluid-filled space.
|
|
|
Nucleolus
|
Structure composed of proteins and nucleic acids found within the nucleus that transcribes RNA.
