What is the primary pigment involved in photosynthesis?
carbon dioxide
chlorophyll
chloroplasts
stomata
What is the equation for photosynthesis?
H2O + CO2 → O2 + C6H12O6
C6H12O6 + 6O2 → 6CO2 + 6H2O
C6H12O6 + 6CO2 → 6H2O + light energy
6CO2 + 6H2O + light energy → C6H12O6 + 6O2
Where does photosynthesis occur in plants?
Cytoplasm
Chlorophyll
Chloroplasts
Mitochondria
What is the main source of energy for photosynthesis?
Water
Glucose
Carbon Dioxide
Sunlight
What is the role of chlorophyll in photosynthesis? Page 133
Chlorophyll is responsible for the synthesis of water in photosynthesis
Chlorophyll releases oxygen during photosynthesis
Absorb light energy and convert it into chemical energy
Chlorophyll helps in the breakdown of glucose
glucose
mitochondria
cytoplasm
As part of the process of photosynthesis, water molecules are broken apart into hydrogen and oxygen atoms. Which atom is used by the plant to build the sugars that plants use for food?
(a)
Exit: Carbon dioxide
Exit: Glucose
Exit: Oxygen
Exit: Water vapor
(a) is a gas that contains (b) atom and (c) atoms
What is a group of atoms bonded together?
Products
Molecule
Microorganism
Reactants
What is a substance that is a part of a reaction and goes through a change?
Reactants
Product
Molecule
Chloroplasts
(a) are an (b) (part of a cell) that contains (c) and where photosynthesis takes place.
Which organelle is responsible making food (glucose) using sunlight?
Cell Membrane
Nucleus
Chloroplast
Mitochondria
Which of the following is the correct equation for PHOTOSYNTHESIS?
light + carbon dioxide + water --> glucose + oxygen
carbon dioxide + sugar + water --> oxygen + light
oxygen + light + water --> carbon dioxide + sugar
carbon dioxide + oxygen + water --> Light+ Sugar
What pigment captures/absorbs sunlight?
stomata
chlorophyll
chloroplast
phloem
What is the tiny openings that let in the carbon dioxide needed for photosynthesis?
stomata
xylem
phloem
chloroplast
What are the 2 products of photosynthesis? The products are the things made in the process of photosynthesis.
water, sunlight
glucose, carbon dioxide
oxygen, glucose
sunlight, oxygen
Which product is "waste" and mostly released by the producer (plant)?
oxygen
carbon dioxide
sugar
glucose
How does oxygen get released by the producer (plant)? Name the structure in the leaf.
stomata
xylem
phloem
chloroplast
Which of the following are TRUE statements? (Select ALL that apply)
Photosynthesis takes place in the chloroplasts of leaf cells
Photosynthesis means "making food using sun"
Photosynthesis can occur in the dark
All plants, plant-like protists, and some bacteria go through photosynthesis
These types of cells are packed tightly together allowing more light. They are near the top surface of the leaf.
Palisade Mesophyll Cells
Spongy Mesophyll Cells
Chloroplasts
Chlorophyll
These types of cells have open spaces between them. Gases for photosynthesis flow through the spaces between them.
Palisade Mesophyll Cells
Spongy Mesophyll Cells
Chloroplasts
Chlorophyll
A series of chemical reactions that convert light energy, water, and carbon dioxide into the food-energy molecule glucose, and give off oxygen.
Cellular Respiration
Photosynthesis
Glycolysis
What is the role of sunlight in photosynthesis?
It helps the plant to grow.
It provides energy to convert carbon dioxide and water into glucose.
It is used to break down glucose into energy.
It is absorbed by chlorophyll to give the plant its green color.
