Botany Notes
Energy Budget of plants:
Plants are the source of energy for all of us and all living things on earth.
Energy is the currency of the universe = $ (work) * Energy budget= must be balanced
Energy budget * Plants collect and process energy * Basic source SUN * Diffuse – need to collect a lot to get fixed energy * (sugar)- LEAVES = solar collector * Everything must be paid for and pay for itself over time
Plants are sentient beings * Perceive environment and respond to it appropriately * Plants grow in response to: the wind, sunlight, root growth * Autotrophs- Photosynthesis * Heterotrophs- eat (engulf, ingest, absorb) * “see at many wavelengths of light” specifically detect, identify colors. * Detect and respond to pressure- (physical= wind, touch, other plants,) * Efficient elegancy designed for life as a photosynthetic autotroph
Senses of a plant
“see”- light, many wavelengths
“hear”- respond to different frequency of sound
“feel”- respond to physical pressure wind weight
“smell”- respond to molecules in the air
“taste”- wet surfaces of cell membranes
Biological- design of living beings and function of parts and pieces whole organisms
Autotrophic * Self feeding * Photosynthetic light putting together collecting lightsugaroil, proteins, pigments, enzymes
Concentrators of Energy
Original source of energy in the universe, sun * Energy released from molecules coming apart explosively= electrons in light * To use this energy we need: solar collectors
Solar collectors: * Leaves= most variable organ in plants * Plants look the way they do and they dont move around because: to be successful in PS autotroph
Plants have indeterminate growth * Keep growing their whole life- constantly: * Making new roots, stems, leaves.
What do plants take to survive?: 1. Sunlight 2. Surface area leaves >> solar collectors 3. Stability
