Photosyntgesis Flashcards
What is the stomata
What is the loss of water through a leaf of a plant
What is needed for photosynthesis to take place
Holes in leaves that allow gas in and out as well as water
Transpiration
CO2, H2O, light, and chlorophyll
What are the three types of photosynthesis
What is the chemical formula for photosynthesis
Photosynthesis that occurs io plants crotesta algae, monera bacteria
6CO2+6H2O–>c6H12O6+6O2
List the electromagnetic spectrum from high to low energy
Gamma rays. X-rays . Ultraviolet. Visible light. Infrared. Microwaves. Radio waves
What does it mean when an object is black
What does it mean when an object is white
No colors are reflected in all are absorbed
All colors are reflected and none are absorbed
What has more energy purple or red
What are two places photosynthesis can occur
Where in the leaves Can photosynthesis occur
Purple because it has shorter wavelengths
In the leaves and stems of plants
The mid layer of a leaf called the Mesophyll layer
In the chloroplasts found in those mesophyll cells
What is the most specific site of photosynthesis
What is what is the function of cuticle
Upper and lower epidermis
The thylakoid
A wax layer to keep water in the leaf
Cells to protect palisade and spongy Mesophyll cell
What is and what is the function of xylem Phloem The vein The bundle sheath cell Stoma Guard cells
To transport water in vein
Transport sugar in the vein
Totransport
To protect transport
Holes that allow gas in and out and water out
Open and close stomata based on hydration
What will happen to a stomata if the cell is dehydrated
What is stroma
How is a granum related to the thylakoids
The stomata will close so water particles cannot escape the cell
Liquid containing enzymes in the chloroplasts around the thylakoid
Granum is a stack of thylakoids
Photophosphorylation
What fuels the Calvin benson cycle
CO2 ATP and NATDPH plus H+ produces
Light reaction
ATP and NADP and H+
Sugar
Light dependent reactions
Light independent reactions
Directly depend on the light has like exits electrons in pigment molecules eventually makes ATP and NATpH or an energy molecule
CO2 along with ATP and NATpH from light dependent reactions are used to generate glucose for the Calvin cycle
What are the products like dependent reactions
What happens in photosystem’s
02 ATP and NADPH
the light reactions take place in a small areas of thylakoid membrane called photosystems
Light hits the chlorophyll molecules to transmit the energy to a special molecule called the reaction center
What happens after light energy hits reaction center
Where did photosystem to get its electrons
Reaction center of pS 2 ejects electron to at electron transport system that passes these electrons to the reaction center of PS/1
Breakdown of H2O as 2h+ + 1/2O2+ 2e-
Primary electronic accepter
What equals NADPH
Leo says ger
Takes in high Energy electron
NADP+2e-+H+
Loss of electrons oxidation, gain electrons reduction
What happens in the electron transport chain when energy is lost
Lost energy is received by an NADP + to form NADPH
