Photosynthesis Basics

We discussed which structure in each plant cell carries out photosynthesis. Which structure, or organelle, did we determine houses this energy-producing process?

• Mitochondria

• Ribosomes

• Chloroplasts

• Cytoplasm

Ok, just to recap what he just explained: In photosynthesis ​ ​ (a)   and ​water are taken into the plant to use to make ​ (b)   gas and ​ (c)   for structures and energy. In cellular respiration, sugar and oxygen are taken in so the cell can produce carbon dioxide and​ ​ (d)   .

• oxygen
• sugars
• carbon dioxide
• water

Answer explanation

To paraphrase what he just explained, plants only reflect _____ light, which is why they appear as they do (in most cases).

Really quickly: Which reactions did he just explain took place in the thylakoids?

• Light Dependent

• Light Independent

• Cellular Metabolism

• None of These

To recap light dependent reactions, which pair is correct:

• Reactants: Oxygen, ATP, and NADPH

  Products: Carbon Dioxide, Light, and ADP

• Reactants: ATP, Glucose, and Carbon Dioxide

  Products: Oxygen, Amino Acids, and GABA

• Reactants: Water, Carbon Dioxide, and ADP

  Products: Oxygen, ATP, and NADPH

• Reactants: Water, Oxygen, and ATP

  Products: Carbon Dioxide, Cellulose, and NADP

What are the reactants in photosynthesis (utilized in the "light reactions")? Click all that apply!

• Water (H20)

• Oxygen (O2)

• Carbon Dioxide (CO2)

• Sugar (C6H12O6)

• Sunlight

The light independent reactions take in​ (a)   gas (through the stomata) sunlight and ​ (b)   , then use the ​ (c)   and ​ ATP molecules to produce ​ (d)   that the plant can use for energy and structure.

• Carbon Dioxide (CO2)
• NADPH+
• Sugars (C6H12O6)
• Oxygen
• Sunlight
• Water
