*Unit 4 Part 1: Photosynthesis Flashcards
Photosynthesis and Cellular Respiration
What is the goal of photosynthesis?
To store energy from the sun in the bonds of glucose
What does it mean to say something is an autotroph?
It makes its own food
What does “auto” mean?
self
Plants are autotrophs
True/False
True
What is needed for photosynthesis?
- Sunlight
- Water
- CO2
What is CO2
Carbon Dioxide
What does photosynthesis produce?
- Oxygen
- Glucose
“Photo” means…
Light
“Synthesis” means…
To create/ The production of
What is the Photosynthesis equation?
CO2 + H2O + SUNLIGHT-> C6H12O6 + O2
What is the Photosynthesis equation in words?
Carbon Dioxide, Water, and Sunlight produces Glucose and Oxygen
What is Waxy Cuticle?
Protective layer on top of leaf
What is Stoma/Stomata?
Openings underneath the leaf that allow water/ carbon dioxide to enter or leave
What are Guard Cells?
Controls when the stoma open and close
What is Mesophyll?
1.Full of chloroplasts
2. Location of photosynthesis
The waxy cuticle, stoma, guard cells, and mesophyll are all…
Parts of a leaf
What is the granum?
Stack of thylakoids that looks like a stack of pancakes
What is a tylakoid?
Individual discs that are part of the granum. This is where light dependent reations take place.
What is the stroma?
Fluid-fill space of the chloroplast where light independent reactions take place.
The granum, thylakoid, and stroma are all…
Parts of the chloroplast
Where do light dependent reactions take place?
Thylakoid
Chlorophyll does what?
Absorbs light
Light energy does what to electrons?
It “excites” them, giving them energy
In light dependent reations, energy is transferred into…
NADPH and ATP
What does NADPH and ATP do in light dependent reations?
They carry energy to the next step
Light dependent reactions release _____ as a waste product.
Oxygen
How do light dependent reactions release oxygen as a waste product?
By splitting water
Where do light independent reactions take place?
In the stroma
The stroma is also called ______ and ______.
Calvin Cycle; Carbon Fixation
What is put together to make sugar?
CO2
CO2 is put together to make what?
sugar
Light independent reactions use _____ from _____ and _____.
electrons; NADPH; ATP
What are the electrons in NADPH and ATP used for in light independent reactions?
For energy needed to use CO2 to make sugar
