Cell wall
|
A rigid substance on the outside of certain cells, usually plant and bacteria cells
|
|
Central vacuole
|
A large vacuole that rests at the center of most plant cells and is filled with a solution which contains a high concentration of solutes
|
|
Chromoplasts
|
Organelles that contain pigments used in photosynthesis
|
|
Cytoplasm
|
A jelly-like fluid inside the cell in which the organelles are suspended
|
|
Cytoskeleton
|
A network of fibers that holds the cell together, helps the cell keep it's shape, and aids in movement.
|
|
Endoplasmic reticulum
|
An organelle composed of an extensive network of folded membranes which perform several tasks within a cell
|
|
Golgi bodies
|
The organelles where proteins and lipids are stored and then modified to suit the needs of the cell
|
|
Ions
|
Substances in which at least one atom has an imbalance of protons and electrons
|
|
Intermediate Filaments
|
Threadlike proteins in the cell's cytoskeleton that are roughly twice as thick as microfilaments.
|
|
Leucoplasts
|
Organelles that store starches or oils
|
|
Lysosome
|
The organelle in animal cells responsible for hydrolysis reactions which break down proteins, polysaccharides, disaccharides, and some lipids

|
Microfilament
|
fine, threadlike proteins found in the cell's cytoplasm.
|
|
Middle lamella
|
The thin film between the cell walls of adjacent plant cells

Waste vacuoles
|
Vacuoles that contain the waste products of digestion
