Chloroplasts and Chlorophyll Flashcards
The process by which plants and other photosynthetic organisms trap the sun’s energy and transform it into energy-rich chemical compounds.
Photosynthesis
The process by which cells break down high-energy compounds and generate ATP.
Cellular Respiration
The direct source of energy for nearly all types of energy-requiring activities of living organisms.
Adenosine Triphosphate (ATP)
Photosynthesis takes Carbon Dioxide, Water and Light Energy and produces what?
Glucose and Oxygen
Photosynthesis is an example of a ________ pathway
- Synthesis larger molecules
Anabolic
Cellular Respiration takes Glucose and Oxygen and produces/releases what?
Produces Carbon Dioxide and Water and releases Energy
Cellular Respiration s is an example of a _________ pathway
- Breaks down large molecules into smaller ones
Catabolic
During Photosynthesis, energy from sunlight is stored in the bonds of what?
Glucose
Plants can convert Glucose into a structural molecule called what?
Cellulose
Plants can convert Glucose into ______ storage molecules like starch.
Energy
an organelle within the cells of plants and certain algae that is the site of photosynthesis
Chloroplasts
What is the inner solution of the Chloroplast called?
Stroma
What are the flattened sacs in Chloroplast called?
Thylakoids
What are the stacks of Thylakoid in Chloroplasts called?
Grana
The molecules that trap solar energy.
- Bound to the Thylakoid membranes
- Gives plants their green color
Chlorophyll
What are the two metabolic pathways in Photosynthesis?
Light dependent and Light Independent reactions
During Light Dependent Reaction, solar energy is trapped in ________ found in the thylakoid membranes of Chloroplast
pigments
Why do leaves look green?
The pigments/chlorophyll absorb almost every color except green, so green is reflected.
Main Photosynthetic pigment
Chlorophyll A
What pigments are found in leaves?
Chlorophyll A, Chlorophyll B, and B Carotene (carotenoid)
B Carotene absorb which lights and are in what colours?
Absorbs Blue and Green, and are yellow, orange, and red in colour
Why does the colour of leaves change in the fall?
Chlorophyll masks the other pigments in the spring/summer. Cooler temperatures in fall stop chlorophyll production, revealing the other carotenoid pigments.
