Module#6 The Cell Flashcards
The breakdown of absorbed substances
Digestion
The transport of dissolved substances into cell
Absorption
The breakdown of food molecules with a release of energy
Respiration
The removal of soluble waste materials
Excretion
The removal of non soluble waste materials
Egestion
The release of biosynthesized substance
Secretion
Maintains the status quo
Homeostasis
Producing more cells
Reproduction
The study of cells
Cytology
Sye tahl’ uh jee
A rigid structure on the outside of certain cells, usually plant and bacteria
Cell wall
These walls are formed on the inside of the original cell wall and are much more rigid, providing better protection for the contents of the cell
Secondary cell wall
Once the secondary cell walls are formed, the original cell wall is usually referred to as the__
Primary cell wall
The thin film between the walls of adjacent plants
Middle lamella
The semipermeable membrane between the cell contents and either the cell wall or the cells surroundings
Plasma membrane
A jellylike fluid inside the cell in which the organelles are suspended
Cytoplasm
Substances in which at least one atom has imbalanced if protons and electrons
Ions
The motion of cytoplasm in a cell that results in a coordinated movement the cells contents
Cytoplasmic streaming
The organelle in animal cells responsible for hydriolysis reaction that breakdown protein, polysaccharides, disaccharides and some lipids
Lysosome
The organelles in which nutrients are converted to energy
Mitochondria
Non membrane bounded organelles responsible for protein synthesis
Ribosomes
An organelle composed of an extensive network of folded membranes that performs several tasks within a cell
Endoplasmic retculum
ER that is dotted with ribosomes
Rough ER
ER that has no ribosomes
Smooth ER
Organelles that store starches or oils
Leucoplasts
Organelles that contain pigments used in photosynthesis
Chromoplast
A large vacuole that rests at center of most plant cells and is filled with a solution that contains a high concentration of solutes
Central vacuole
Vacuoles that contain the waste products of digestion
Waste vacuoles
The process by which a cell engulfs a foreign substances or other cells
Phagocytosis
A vacuole that holds the matter which a cell engulfs
Phagocytize vacuole
Vesicle formed at the plasma membrane to allow the absorption of large molecules
Pinocytic vesicle
Vesicle that holds secretion products so that they can be transpired to the plasma membrane and released
Secretion vesicle
The organelles where proteins and lipids are stored and and then modified to suit the needs if the cell
Golgi bodies
Spiral strands of protein molecules that form a tubelike structure
Microtubule
