Cells
most basic unit of life
Tissues
collection of like cells
Organs
multiple tissues working together
Organ System
a group of organs that serve a function
Organism
individual life form
Benign tumor
not cancerous; no metastasis
Malignant tumor
cancerous; undergoes metastasis
Mitochondria
powerhouse of the cell
Nucleus
control center of the cell which contains genetic material
Cell membrane
encloses cell contents; keeps unwanted substances out
Nucleolus
produce and assemble the cells ribosomes
Smooth ER
enzymes speed up reactions involved with metabolizing lipids
Rough ER
creates proteins
Capsule
protect bacteria from attack of white blood cells; keeps cells from drying out; help bacteria attach to other cells
Cell wall
provides protection to the cell; provides circulation, water, and minerals
Vacuole
storage structure in a cell; holds food for later use; maintains water balance
Lysosomes
Digest biological molecules
Glycoprotein
reproduction, immune system, hormones, and protection of cells and organisms
Peripheral protein
support, communicate, enzymes, and molecule transfer in the cell
Chromosomes
carry gene traits; determines the genetic sex
Cytoplasm
provides a platform upon which other organelles can operate within a cell
Cilia
help the cell move around; prevent debris and possible pathogens from invading the body
Cytoskeleton
provides structure and support; organelle transport; cell division
Flagella
enables many protozoa, bacteria and spermatozoa
Transmembrane protein
connect cells together; act as enzymes
Ribosome
translates genetic code into amino acids that form proteins
Golgi body
separates proteins; creates new proteins
