What are the products of photosynthesis?
glucose and oxygen
What are the reactants of photosynthesis?
water light and carbon dioxide
Where does the Calvin cycle take place?
A photon first enters the cells at photosystem
In the Calvin cycle, how many molecules of ATP are required?
In the Calvin cycle, how many molecules of NADPH are required
What are the openings on leaves called?
Do leaves have layers? yes or no
Does photosynthesis only happen during the day? Why or why not?
no not all parts of photosynthesis require light
What is the chemical equation for photosynthesis?
A particle of light energy is known as a
A stack of thylakoids is known as a
Why would a flower with white petals have those petals turn orange when placed in orange water?
the color would be absorbed by the chlorophyll and would spread throughout the leaf
Why many plants look green?
they have chlorophyll which is green and they reflect green
Why can plants not grow well under green light?
plants are bad at absorbing green and good at reflecting it
The fluid inside of thylakoids is called
The fluid inside of chloroplasts is called
On what membrane does the Electron Transport Chain occur?
Write the sequence of the Electron Transport Chain including where a photon goes first, which photosytem comes first, etc.
photosystem 2-cytochrome-photosytem 1
Where does all energy on Earth come from?
What is an autotroph?
organism that creates its own food
What does the stem of a flower do for that flower?
support/keep it standing
What do the roots of a plant do?
absorb water and minerals and anchor it
What do the leaves of a plant do?
What is one form excess glucose is stored as?
What is turgor pressure(for plants)?
water pressure, helps hold plant up
How long did it take for photosynthesis to go from bacteria to land plants that used it?
about 3 billion years
Who discovered photosynthesis?
What is the pigment that makes chloroplasts green?
Hypothesis. Why do you think some plants have waxy leaves, or waxy outsides?
keep water in and keeps excess water out
What are the three major steps of the Calvin cycle?
carbon fixation and reduction and regeneration
What is the chemical formula of glucose?
What is the chemical formula of atmospheric oxygen?
What is the chemical formula of carbon dioxide?
