Cell activity

Transport, Photosynthesis, Respiration

QuestionAnswer
active transport moving material across cell membrane against concentration gradient requiring energy
passive transport movement of materials across cell membrane from high to low concentration not requiring energy (diffusion and osmosis)
hypertonic solution with a greater concentration of solutes than the cell (in our case)
hypotonic solution with lower concentration of solutes than the cell (in our case)
isotonic when the concentration of two solution is the same
cell basic unit of all living things enclosed in a barrier that separates its inside from its surroundings
prokaryote cell with no true nucleus or no other membrane bound organelles, all unicellular
eukaryote organized cell with a nucleus and other bound organelles that make up all plants and animals
organelle specialized structures that perform important cellular functions in eukaryotic cells
ATP adenosiine triphosphate. The energy used in the cell.
semi-permeable a membrane that only allows certain molecules to pass through it
diffusion the action of molecules moving from an area of high concentration to an area of low concentration
osmosis diffusion of water through a semi-permeable membrane
photosynthesis carbon dioxide and water get together in sunlight to form glucose and oxygen
aerobic cellular respiration glucose and oxygen get together with some energy to form carbon dioxide and water
chloroplast site of photosynthesis
mitochondria site of cellular respiration
anaerobic respiration producing ATP in a cell without any oxygen present
xylem this is responsible for taking water from the roots to the rest of the plant
green chloroplasts can absorb all light from the visible light spectrum except this col
carbon dioxide product of cellular respiration and reactant of photosynthesis, we exhale it
oxygen product of photosynthesis and reactant in aerobic respiration, we inhale it
stomata tiny openings in leaves that allow carbon dioxide into the plant and oxygen and water out
chlorophyll green pigment in chloroplast that traps light energy for photosynthesis
autotroph an organism that manufactures its own food
heterotroph an organism that is dependent on taking in other organisms for nutrition
roots the majority of water taken in by plants enters here
algae single cell organism that along with plants does photosynthesis supplying the Earth with oxygen
