|
catabolism
|
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 called genes. There are 46 chromosomes (23 pairs) in every cell except for the egg and sperm cells, which contain only 23 individual, unpaired chromosomes.
|
|
|
cytoplasm
|
All the material that is outside the nucleus and yet contained within the cell membrane.
|
|
|
endoplasmic reticulum
|
Structure (canals) within the cytoplasm. Site in which large proteins are made from smaller protein pieces.
|
|
|
DNA
|
Chemical found within each chromosome. Arranged like a sequence of recipes in code, it directs the activities of the cell.
|
|
|
metabolism
|
The total of the chemical process in a cell. It includes both catabolism and anabolism.
|
|
|
genes
|
Regions of DNA within each chromosome.
|
|
|
nucleus
|
Control center of the cell. It containes chromosomes and directs the activities of the cell.
|
|
|
mitochondria
|
structures in the cytoplasm in which foods are burned to release energy.
|
|
|
anabolism
|
Process of building up complex materials (proteins) from simple materials.
|
|
|
karyotype
|
Picture of chromosomes in the nucleus of a cell. The chromosomes are arranged in a numerical order to determine their nubmer and structure.
