Biology Final

Cell Transport, Cell Division, Photosynthesis and Biomolecules

TermDefinition
Selective Permiability Cell membrane allows only certain substances in and out of the cell
Osmosis Diffusion of water across a cell membrane large particles can't move so water moves instead
Isotonic Concentration is equal on both sides
Diffusion Small non polar particles pass through the cell membrane
Hypotonic Low amount of solute inside compared to the solution outside
Concentration Gradient One side of the membrane contains a higher amount of particles
Hypertonic Contains a high amount of solute inside than outside
Homologous Chromosomes A chromosome pair
Anaphase Duplicated pairs are pulled apart to opposite ends of the cell
Daughtercell Two new cells, the divided parent cell
Prophase Nucleus membrane disappears, chromosome pairs of visible
Telophase Nuclear membrane appears around cells, both cells begin interphase again
Metaphase fibers line Chromosomes up in the middle
Parent cell The cell ready to duplicate
Passive transport Transports of molecules that do not require energy
Active transport Transports of molecules that require energy
Interphase Cell grows and duplicates DNA
Mitosis Division of nucleus and DNA
Cytokinesis Division of 1 cell into 2 genetically identical daughter cells
4 Biomolecules Carbohydrates, Lipids, Proteins and Nucleic Acids
Carbohydrates function immediate energy
Lipids function Long term energy storage
Nucleic Acids function Stores genetic material
Proteins function Do work, building cell parts, transferring molecules
Photosynthesis the process where plants use sunlight and carbon dioxide to generate food
Light dependent reaction a series of biochemical reactions in photosynthesis that require light energy
Chloroplast a oval structure that contains chlorophyll and photosynthesis takes place
Chlorophyll a green pigment in the plant that captures and stores sunlight
Light Independent reaction a chemical reaction that converts carbon dioxide and other compounds into glucose
Inputs of photosynthesis Sunlight, CO2, H2O
Outputs of photosynthesis O2, Glucose
How CO2 and O2 exit the leaf Stomata
Cellular respiration a chemical process in a plant that produces food
Glucose sugar, food, source of energy
ATP Energy stored in C-C and C-H bonds
Mitochondria Where cell respiration happens, the powerhouse of the cell
