What makes a plant? BOT 110 What makes a plant? cellular features use of water alternation of generation growth morpho-anatomy dispersal and survival Cellular Features Pigments Chlorophyll – photosynthesis Carotenoids – photosynthesis, photoprotection and pollinator attraction Anthocyanin – attraction of pollinator and seed disperser, and photoprotection Cellular Features Anabolism Plants make 100% of the amino acids, proteins, lipids, nucleic acids, vitamins, and other biomolecules they need for growth. Plants also produce secondary metabolites for ecological functions. All the major anabolic pathways take place in the plastids. Cellular Features Cell walls nonliving material outside the cell membrane major evolutionary advancement needed for plants to colonize the land composed of cellulose and other organic polymers and may contain active enzymes. Use of water Plants use water, and the properties of water, in unique ways. Alternation of generation The life cycle alternates between a haploid gametophyte and a diploid sporophyte. Raven et al. 2020 Growth Plants produce new cells in meristems throughout their life cycle. Morphoanatomy The plant body has four main organs that are made up of three tissue types. Dispersal and Survival Fruit disperses seeds through space Dormancy disperses seeds through time. Many plant reproductive strategies have coevolved with animals. Thanks! Any questions?
