Aim: How do autotrophic and heterotrophic nutrition differ?
Autotrophs vs. Heterotrophs Autotrophs – make own food Heterotrophs – get food from environment
Common “Regents Difficulties” Autotrophic Nutrition (regents definition) -process by which organisms convert inorganic substances into organic substances… Heterotrophic Nutrition (regents definition) -process by which organisms take in preformed organic compounds………
Why is it called PHOTO …….SYNTHESIS? Photo …….. Light Synthesis…….. To make Photosynthesis: The process where light energy is converted to useable energy (glucose)
Why is photosynthesis important? It produces glucose and oxygen which are needed to carry out cellular respiration
Where in plants does photosynthesis take place? Leaf
What organelle in the cell does photosynthesis take place? CHLOROPLAST Contains a pigment called chlorophyll
Chlorophyll does not absorb green light!!! Why are plants green? Chlorophyll does not absorb green light!!!
What do plants need in order to maintain homeostasis? Light energy From the sun Chlorophyll pigment Enzymes
Raw materials end products Raw materials: what is being used (left side of the arrow) End products: What is produced (right side of the arrow Raw materials end products
Raw materials of photosynthesis: water (H2O) and CO2 (Carbon Dioxide) The end products of photosynthesis: C6H12O6 (glucose) and O2 (oxygen)
Chemical Equation for photosyntesis enzyme 6H2O + 6CO2 ----------> C6H12O6+ 6O2 Why is glucose and oxygen an important end product? They are used for cellular respiration
Where do plants get energy to make their own food? SUN
