Chlorophyll
A green pigment found in the chloroplasts of plants, algae, and some bacteria
Tissue
A group of similar cells that perform the same function.
vaccine
A harmless variant or derivative of a pathogen that stimulates a host's immune system to mount defenses against the pathogen
Cytoplasm
A jellylike fluid inside the cell in which the organelles are suspended
Organism
A living thing
Cytoskeleton
A network of fibers that holds the cell together, helps the cell to keep its shape, and aids in movement
Golgi body
A structure in a cell that receives proteins and other newly formed materials from the endoplasmic reticulum, packages them, and distributes them to other parts of the cell.
Organelle
A tiny cell structure that carries out a specific function within the cell. small organ.
Virus
A tiny, nonliving particle that invades and then reproduces inside a living cell.
Bacteriophage
A virus that infects bacteria
Lysosomes
An organelle containing digestive enzymes
Chloroplast
An organelle found in plant and algae cells where photosynthesis occurs
Vacuole
Cell organelle that stores materials such as water, salts, proteins, and carbohydrates
Eukaryotic cells
Contain a nucleus and other organelles that are bound by membranes.
Nucleus
Control center of the cell
Nucleolus
Found inside the nucleus and produces ribosomes. mini nucleus.
Ribosomes
Makes proteins
Mitochondria
Powerhouse of the cell
gene therapy
The insertion of working copies of a gene into the cells of a person with a genetic disorder in an attempt to correct the disorder
prokaryotic cell
cell lacking a nucleus and most other organelles
5 levels of organization
cell, tissue, organ, organ system, organism
cell wall
strong, supporting layer around the cell membrane in some cells
cell membrane
thin, flexible barrier around a cell; regulates what enters and leaves the cell
Chromosomes
threadlike structures made of DNA molecules that contain the genes
endoplasmmic reticulum
transports protiens.
active virus
viruses that enter cells and immediately begin to multiply- the cell dies quickly
Endoplasmic Reticulum
an internal membrane system in which components of cell membrane and some proteins are constructed
nuclear membrane
controls what goes in and out of the nucleus
organ system
group of organs that work together to perform a specific function
latent virus
hides in the host cell without destroying it
