End of Chemistry notes:
Chemical reaction: the chemical composition of matter is changed in a reaction
- in order to have a balanced chamical reaction, the number of each element must be the equal on both sides
REACTIONS NEVER CREATE OR DESTROY MATTER, THEY REARRAGE IT
Photosynthesis:
-converts energy from sun energy into chemical energy of organic compounds
-occurs in plants, some protists and some bacteria
-Autotrophs- make own food, need inorganic compounds to make organic compounds, these are the producers
-Heterotrophs- cannot make its own food, they eat, dependent on autotrophs, these are the consumers
Photosynthesis occurs in CHLOROPLASTS (mainly the leaves of a plant)
-double membrane envelope
-inner membrane encloses stroma- fluid where sugars are made
-thylakaids- sacs in stroma
-grana=stacks of thylakaids
Homework: read chapter 7
