Cell Structure
This is the chromosome-containing organelle of a eukaryotic cell
What is the NUCLEUS?
This organelle consists of stacks of flat membranous sacs that modify, store, and route products of the endoplasmic reticulum
What is the GOLGI APPARATUS?
This is how DNA exists when the cell is not dividing. It is made up of DNA plus proteins
What is CHROMATIN?
This organelle functions as the site of protein synthesis
What is the RIBOSOME?
This is a membrane-enclosed sac taking up most of the interior of a plant cell
What is the CENTRAL VACUOLE?
This organelle contains enzymes that transfer hydrogen from various substrates to oxygen, producing and then degrading hydrogen peroxide
What is the PEROXISOME?
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
What are MICROTUBULES?
This is a short cellular appendage specialized for locomotion
What is the FLAGELLA?
This is an extensive membraneous network in eukaryotic cells that is composed of ribosome-studded and ribosome-free regions
What is the ENDOPLASMIC RETICULUM (ER)?
These are used in muscle contraction, cell motility, and for resisting pulling forces in the maintenance of cell shape
What are ACTIN FILAMENTS (or microfilaments)?
This is where metabolism of carbohydrates and detoxification of drugs occur
What is the SMOOTH ENDOPLASMIC RETICULUM (SER)?
This organelle serves as the site of cellular respiration
What is the MITOCHONDRIA?
These help maintain the shape of the cell by bearing tension (resisting pulling forces) and are made up of a diverse family of proteins
What are INTERMEDIATE FILAMENTS?
This organelle is essentially a membrane-enclosed bag of hydrolytic enzymes
What is the LYSOSOME?
This is made up of a phospholipid bilayer and is the outer boundary of an animal cell
What is the PLASMA MEMBRANE?
