Anabolism | Process of building up complex materials (proteins) from simple materials |
Catabolism | Process of breaking down complex materials (foods) to form simpler substances and release energy |
Cell Membrane | Sturcture 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. |
Cytoplasm | All of the material that is outside the nucleus and yet contained within the cell membrane |
DNA | Chemical found within each chromosome. Arranged like a sequence of recipes in code, it directs the activities of the cell |
Endoplasmic Reticulum | Structure (canals) within the cytoplasm. Site in which large proteins are made form smaller protein pieces. |
Genes | Regions of DNA within each chromosome |
Karyotype | Picture of chromosomes in the nucleus of a cell. Chromosomes are arranged in a numerical order to determine their number and structure |
Metabolism | The total of the chemical processes in a cell. It includes both catabolism and anabolism |
Mitochondria | Structures in the cytoplasm in which foods are burned to release energy |
Nucleus | Control center of the cell. It contains chromosomes and directs the activities of the cell |
