Cell Structure
This is the chromosome-containing organelle of an eukaryotic cell.
nucleus
This is how DNA exists when the cell is not dividing. It is made up of DNA plus proteins
chromatin
This is formed when plasma membranes of neighboring cells in a layer are fused, forming a barrier that
prevents leakage of extracellular fluid across the layer
tight junctions
This organelle consists of stacks of flat membranous sacs that modify, store, and route products of the
endoplasmic reticulum.
golgi apparatus
This is a membrane-enclosed sac taking up most of the interior of a plant cell.
vacoule
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
In plants, these structures allow movement of cytoplasm from one cell to another
plasmodesmata
This organelle functions as the site of protein synthesis
ribosomes
This is an organelle found in plants that absorbs sunlight and uses it to drive synthesis of organic
compounds.
chloroplast
These are used in muscle contraction, cell motility, and for resisting pulling forces in the maintenance of
cell shape. These help maintain the shape of the cell by bearing tension (resisting pulling forces) and are
made up of a diverse family of proteins
microfilaments
Plant cells have a plasma membrane, which is then surrounded by this
cell wall
These connections provide cytoplasmic channels between adjacent animal cells
gap junction
This is an extensive membranous network in eukaryotic cells that is composed of ribosome-studded and
ribosome-free regions.
endoplasmic recticulm
This is made up of a phospholipid bilayer and is the outer boundary of an animal cell.
cell membrane
These junctions fasten animal cells together like rivets.
desmosomes
This is a short cellular appendage specialized for locomotion.
flagella
This organelle serves as the site of cellular respiration
mitochondria
This is where metabolism of carbohydrates and detoxification of drugs occur
smooth ER
A young plant cell first secretes a relatively thin and flexible wall that is called this
primary cell wall
This organelle contains enzymes that transfer hydrogen from various substrates to oxygen, producing and
then degrading hydrogen peroxide
peroxisomes
