Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a by-product.How guard cells control the size of the tomatoesIn sunlightat nightGuard cells cover light to chemical energyWater potential is loweredGuard cells have thicker wall on one side of the cellpotassium ions accumulate in guard cellswater from neighboring epidermis cells enter guard cells by osmosiscauses swollen guard cells to become more curved and pull atoms openincreases turgidity making it swollenpotassium ions diffuse outwater potential in guard cells increaseguard cells become flaccid and atoms releasewater leaves cells by osmosisWhat happens to produced glucoseConverted to sucrosereacts with mineral salts absorbed from soilexcess stored as starch in leavesConverted to fatsConverted to amino acids and proteinsbroken down to release energy to vital activesHow plants absorb sunlightChlorophyllGives plants its green colorPigment in plants that absorb sunlightfor storageUsed in cellular respirationmight be converted back to glucosetransported to other parts of the plantseedsstem tubersroot tubersto form amino acids in leaves
