Cell Structure
This is the chromosome-containing organelle of an eukaryotic cell.
nucleus
This organelle is essentially a membrane-enclosed bag of hydrolytic enzymes.
lysosome
This is how DNA exists when the cell is not dividing. It is made up of DNA plus proteins.
Chromatin
This organelle functions as the site of protein synthesis.
ribosomes
This is a membrane-enclosed sac taking up most of the interior of a plant cell.
central vacuole
This organelle consists of stacks of flat membranous sacs that modify, store, and route products of the endoplasmic reticulum.
Golgi apparatus
These are used as guide tubes for movement of materials, for separation of chromosomes during cell division, and for maintaining the shape of cells by assuming a compression-resisting role.
Microtubules
This is a short cellular appendage specialized for locomotion.
flagellum
This is an organelle found in plants that absorbs sunlight and uses it to drive synthesis of organic compounds.
chloroplast
This organelle contains enzymes that transfer hydrogen from various substrates to oxygen, producing and then degrading hydrogen peroxide.
peroxisome
These are used in muscle contraction, cell motility, and for resisting pulling forces in the maintenance of cell shape.
Microfilaments (actin filaments)
This is where metabolism of carbohydrates and detoxification of drugs occur.
Smooth ER
This is an extensive membranous network in eukaryotic cells that is composed of ribosome-studded and ribosome-free regions.
endoplasmic reticulum
These help maintain the shape of the cell by bearing tension (resisting pulling forces) and are made up of a diverse family of proteins.
intermediate filaments
This organelle serves as the site of cellular respiration.
mitochondrion
This is made up of a phospholipid bilayer and is the outer boundary of an animal cell.
plasma membrane (cell membrane)
