Document Summary
Animals need to eat plants to get energy) they also use co2 and this process is called photosynthesis. Some are heterotrophic: living on organic carbon obtained from other plants: ex. Monotropa uniflora is a white flower therefore it can"t photosynthesize because it lacks chlorophyll: this can be done via mycorrhizal fungi which is a symbiotic relationship. Eukaryotic (carry organelles) eukaryotes aren"t limited to plants they also include fungi, animals and protists. Photoautotrophs (refer to definition) although there are some exceptions ex. Cell walls: for extra protection, rigidity and strength, animals don"t have cell walls. Alternation of generations life cycle (2 stages: diploid sporophyte produces spores, haploid gametophyte produces gametes. Shoot system above ground incl. leaves, stems, flowers, fruits the last 2 are for seed dispersal. Root system below ground incl. nonphotosynthetic roots for anchoring and nutrient absorption. Plant bodies are dendritic (spreading and branched in form) Vascular plant body continue to grow (indeterminate growth)
