Anabolism
|
Process of building up complex materials (proteins) from simple materials
|
Cataboloism
|
Process of breaking down complex materials (foods) to form simpler substances and release energy
|
Cell membrane
|
Structure surrounding and protecting the cell. It determines what enters and leaves the cell
|
Chromosomes
|
Rod-shaped structures in the nucleus that contain regions of DNA (genes). 46 in somatic cells and 23 in sex cells
|
Cytoplasm
|
All the material that is outside of the nucleus but contained within the cell membrane
|
DNA
|
Chemical found within each chromosome; acts as a code to direct the activity of cells
|
Endoplasmic reticulum
|
Canal-like structures in the cytoplasm where large proteins are synthesized; ribosomes may be found on ER
|
Genes
|
Regions of DNA within each chromosome
|
Karyotype
|
Picture of nuclear chromosomes arranged in numerical order to determine number and structure; used for establishing birth defects
|
Metabolism
|
The total chemical processes in a cell - includes both anabolism and catabolism
|
Mitochondria
|
Structures in the cytoplasm in which foods are burned to release energy
|
Nucleus
|
Control center of the cell; contains chromosomes and directs cell activity
|
Cell types and their descriptions
|
Muscle: long and slender fibers
epithelial: square and flat
nerve cell: long with fibrous extensions
fat cell: large empty spaces for fat storage
|
Types of tissue
|
Epithelial, muscle, connective, nerve
|
Digestive System organs
|
Mouth, pharynx, esophagus, stomach, intestines, liver, gallbladder, pancreas
