FCAT Review Life Science What does Being Alive mean?
Made of cells Respond to stimuli Respire (use energy) Adapt Reproduce Excrete wastes Secrete
Have a life span Life Needs:
Energy (solar or chemical) Water Tolerable Temperatures Light Agreeable Atmosphere Structure of the Cell Single Cell vs. Multicellular
Cell Organization
Atom Molecule Organelle Cell Tissue Organ System Organism
Major Systems Excretory Respiratory Male Reproductive
Digestive Female Major Systems Nervous Skeletal
Circulatory Muscular Chemistry of the Cell Cells are made of atoms and molecules
Carbon, Oxygen, Hydrogen, Iron, Sodium, Potassium, etc. Organic Organic compounds contain carbon
Inorganic Carbohydrates, proteins, fats, nucleic acids, etc. Inorganic compounds are also necessary for life Water, salt, vitamins, etc.
Cell Transportnote error on class notes Passive Transport Exocytosis Active Transport Endocytosis Cellular Respiration
organisms use oxygen to break down glucose and release water and carbon dioxide as waste C6H12O6 + 6O2 Energy + 6CO2 + 6H2O Photosynthesis plants use solar energy to make glucose from water and carbon dioxide and release oxygen as waste
Energy + 6CO2 + 6H2O C6H12O6 + 6O2 Mitosis Cell division for body cells - diploid Meiosis
Cell division to produce sex cells - haploid DNA Nitrogen bases Adenine Thymine
Guanine Cytosine Sexual vs. Asexual Reproduction Heredity passing of traits from parents of offspring Alleles different forms a gene has for a trait
A dominant allele for a trait (upper case) a recessive allele for a trait (lower case) Heterozygous different alleles Homozygous identical alleles
