Chapter 10: Photosynthesis Flashcards
What is photosynthesis?
The process of solar energy that is converted to chemical energy
What are autotrophs?
Autotrophs are organisms that sustain themselves and don’t eat from other organisms
How has photosynthesis evolved?
Prokaryotes
What are plants?
Almost all are photoautotrophs
What are heterotrophs?
Organisms that do not sustain themselves and eat from other organisms
What are humans?
Heterotrophs because we consume other organisms and mostly depend on photoautotrophs
Where did chloroplasts evolve from?
Most likely evolved from photosynthetic bacteria(prokaryotes)
What is the stomata?
Pores where carbon dioxide enters and oxygen leaves from and is in the bottom of the leaf
What is the stroma?
A dense fluid that is surrounded by two membranes
What are thylakoids?
connected sacs in the chloroplasts
What is chlorophyll?
The pigment of leaves or plants
What is the Calvin Cycle?
the synthesis part in photosynthesis
What are light reactions?
The photo part in photosynthesis
What do light reactions do?
Split H2O, release O2, Reduce the electron acceptor NADP+ to NADPH, and Generate ATP from ADP by photophosphorylation
