7 Life processes |
M- Metabolism R- Reproduction S- sensitivity G- growth R- respiration E- excretion N- nutrition |
|
|
|
Nutrition |
Food - Energy Autotrophic- can produce own food Heterotrophic- can not |
Auto and Hetero met |
|
|
Metabolism |
Chemical process, different reactions - state of cell CATABOLISM (energy released) ANABOLISM (stored) |
Ana and Cata |
|
|
Transportation |
Animals- circulatory system (heart and blood) Plant- vascular tissues (xylem and phloem) |
|
|
|
Respiration |
Exchange gas, burns food Breaks down Glucose for energy Redox reaction (with or without oxygen) Happens in mitochondria Releases energy in form of ATP ( AEROBIC AND ANAEROBIC) |
|
|
|
Reproduction |
Biological process , Offspring determines continuity of species Sexual and asexual |
|
|
|
Excretion |
Elimination of toxic waste Humans: metabolic/excretory system |
|
|
|
Cell structure 9 |
Cell membrane Nucleus Mitochondria Ribosomes Vacuoles Endoplasmic reticulum Golgi complex Lysomes Cytoplasm |
|
|
|
Cell membrane |
Controls movement of materials in/out of cell through passive or active |
|
|
|
Nucleus |
Genes, dna Control and regulate |
|
|
|
Mitochondria |
Generates energy Glucose breakdown Cell respiration |
|
|
|
Ribosomes |
Protien synthesis |
|
|
|
Vacuoles |
Stores waste |
|
|
|
Smooth and rough er |
Produces membrane Synthesis of protein and lipids |
|
|
|
Golgi complex |
Sort modify and package proteins/lipids |
|
|
|
Lysomes |
Ingest and dissolve foreign substances |
|
|
|
Cytoplasm |
Supports organelle |
|
|
|
Passive |
Little to no energy High to low DIFFUSION- movement of solvent OSMOSIS- movement of water BALANCE |
|
|
|
Active |
Needs energy ATP Against concentration gradient Carrier proteins Endocytosis- englulfment of molecules |
|
|
|
Tissues 4 |
Epithelial- body surface Lines organ ducts etc Forms glands
Connective- protects supports and binds organs Stores fat
Muscular- movement and generates heat Voluntary skeletal Involuntary smooth and cardiac Organ function
Nervous- detects changes in body and responds correspondingly |
|
|
|
Components of human system 7 |
Respiratory Circulatory Digestive Excretory Reproductive Endocrine Immune |
|
|
|
Circulatory |
Transport nutrients Cardiac muscle |
|
|
|
Digestive |
Ingestion breakdown and absorption Smooth muscle |
|
|
|
Excretory |
Expulsion of wastes |
|
|
|
Endocrine |
Production and regulation of hormones |
|
|
|
Immune |
Defend against infection |
|
|
|
Aerobic |
Break down glucose to produce energy (in steps) Mitochondria Glucose + oxygen = carbon dioxide + water + energy |
|
|
|
Anaerobic |
Break down Glucose without use of oxygen Less effiecnet, small amount of energy Cytoplasm Glucose = lactic acid +energy
