Question | Answer |
Plasmalemma | Isolates; protects; is sensitive; supports; control of entrance/exit of materials |
Cytosol | Distributes materials by diffusion; stores glycogen, pigments and other materials |
Cytoskeleton | Strength and support; movement of cellular structures and materials |
Microvilli | Increase surface area to facilitate absorption of extracellular materials |
Centrosome | Essential for movement of chromosomes during cell division; organisation of microtubules in cytoskeleton |
Cilia | Movement of materials over cell surface |
Ribosomes | Protein synthesis |
Mitochondria | Produce 95% of ATP required by the cell |
Nucleus | Control of metabolism; storage and processing of genetic info; control of protein synthesis |
Nucleolus | Site of rRNA synthesis and assembly of ribosomal subunits |
Rough ER | Modification and packaging of newly synthesized proteins |
Smooth ER | Lipid, steroid, and carbohydrate synthesis; calcium ion storage |
Golgi Apparatus | Storage, alteration and packaging of secretory products and lysosomal enzymes |
Lysosome | Intracellular removal of damaged organelles of of pathogens |
Peroxisome | Catabolism of fats and other organic compounds; neutralization of toxic compounds generated in the process |
Facilitated diffusion | Carrier molecules transport materials down a concentration gradient |
Osmosis | Movement of water molecules toward high solute concentrations; requires membrane |
Diffusion | Molecular movement of solutes; direction determined by relative concentrations |
Active transport | Carrier molecules work despite opposing concentration gradients |
Endocytosis | Formation of membranous vesicles containing fluid or solid material at the plasmalemma |
Exocytosis | Fusion of vesicles containing fluids and/or solids with the plasmalemma |
Integumentary system | protection from environmental hazards, temperature control |
Skeletal system | Support, protection of soft tissues; mineral storage; blood formation |
Muscular system | Locomotion, support, heat production |
Nervous system | Directing immediate responses to stimuli, usually by coordinating the activities of other organ systems |
Endocrine system | Directing long-term changes in the activities of other organ systems |
Cardiovascular system | Internal transport of cells and dissolved materials, including nutrients, wastes and gases |
Lymphoid system | Defense against infection and disease |
Respiratory system | Delivery of air to sites where gas exchange can occur between the air and circulating blood |
Digestive system | Processing of food and absorption of organic nutrients, minerals, vitamins, and water |
Urinary system | Elimination of excess water, salts and waste products; control of pH |
Reproductive system | Production of sex cells and hormones |
Homeostasis | Maintenance of a stable environment |
Positive feedback | Increases the intensity of the change or magnifies the change |
Negative feedback | Returns the change variable back to normal levels |
