Botany Introclassification
Classification Multicellular Eukaryote Have cell walls made of cellulose Carry out photosynthesis AND respiration Most are autotrophs A few are parasites (live on living organisms) or saprobes (live on dead organisms) Store energy as starch (carbohydrates) Sunlight Water Minerals Gas Exchange (CO2 in: O2 and some CO2 out) Transport of water and nutrients throughout the plant body Remember Photosynthesis: 6H2O + 6CO2 ? C6H12O6 + 6O2 (water + carbon dioxide + sunlight ? glucose + oxygen) Plants life cycles have two alternating phases known as alternation of generations: A diploid (2N) phase known as the sporophyte (spore producing plant). A haploid (N) phase known as the gametophyte (gamete producing plant)
