Photosynthesis 5.1 Overview

Question 1

autotroph

Answer 1

an organism capable of producing its own food

Question 2

chlorophyll

Answer 2

the green pigment that captures the light energy that drives the reactions of photosynthesis

Question 3

heterotroph

Answer 3

an organism that consumes other organisms for food

Question 4

chloroplast

Answer 4

the organelle where photosynthesis takes place

Question 5

granum

Answer 5

a stack of thylakoids located inside a chloroplast

Question 6

light-dependent reaction

Answer 6

the first stage of photosynthesis where visible light is absorbed to form two energy-carrying molecules (ATP and NADPH)

Question 7

mesophyll

Answer 7

the middle layer of cells in a leaf

Question 8

photoautotroph

Answer 8

an organism capable of synthesizing its own food molecules (storing energy), using the energy of light

Question 9

pigment

Answer 9

a molecule that is capable of absorbing light energy

Question 10

stoma

Answer 10

the opening that regulates gas exchange and water regulation between leaves and the environment; plural: stomata

Question 11

stroma

Answer 11

the fluid-filled space surrounding the grana inside a chloroplast where the Calvin cycle reactions of photosynthesis take place

Question 12

thylakoid

Answer 12

a disc-shaped membranous structure inside a chloroplast where the light-dependent reactions of photosynthesis take place using chlorophyll embedded in the membranes

Question 13

Photosynthesis

Answer 13

Photosynthesis uses solar energy, carbon dioxide, and water to release oxygen and to produce energy-storing sugar molecules. Photosynthesis requires sunlight, carbon dioxide, and water as starting reactants

Question 14

What is the Photosynthesis equation?

Answer 14

Carbon dioxide 6 CO2 + Water 6 H2O -> (sunlight)-> Glucose C6H12O6 + Oxygen 6 O2
