What are the things that you cannot live without?
Photosynthesis

“other feeder” Has to consume other organisms to get energy

“other feeder” Has to consume other organisms to get energy
Autotroph“self-feeder” Has the ability to make its own fuel to get
energy
Conservation of EnergyEnergy cannot be created or destroyed, it can
only be converted to a different form.
What does this mean for plants?
Conservation of EnergyEnergy cannot be created or destroyed, it can
only be converted to a different form.
What does this mean for plants?Plants cannot just create their own energy
from nothing
Plants get their energy from the Sun
Plants cannot just use light energy directly,
they have to convert it to a usable form first!
Photosynthesis Equation
Carbon Dioxide + Water => Sugar + Oxygen
CO2 + H2O => CH2O + O2
Photosynthesis Equation
Carbon Dioxide+Water=>Sugar+Oxygen
CO2 + H2O => CH2O + O2
Don’t be scared! We will be going over this in more detail later
This would be a slide with the plant leaf and chloroplast diagrams from their textbook
Plant Parts SummaryStomata are pores in the leaf that regulate
CO2 intake and O2 outputMesophyll Cells are cells at center of leaf cell
layers which contain chloroplastsA Chloroplast is the organelle where
photosynthesis takes place! Thylakoid = chlorophyll is located in the thylakoid
membrane Granum (plural: grana) = stack of thylakoids Stroma = area outside grana where complex sugars
are created
PigmentsChlorophyll is a pigment that absorbs
sunlight and incorporates the energy into the process of photosynthesis
Chlorophyll is not the only pigment that exists in a leafWhat happens to the leaves in fall?
