Photosynthesis Concepts and Processes

What is the fundamental process by which plants convert light energy into chemical energy?

• Cellular respiration

• Fermentation

• Photosynthesis

• Glycolysis

Which of the following are the primary inputs required for photosynthesis?

• Glucose, oxygen, and light

• Light, water, and carbon dioxide

• ATP, NADPH, and oxygen

• Water, oxygen, and glucose

The term "photosynthesis" is derived from Greek words. What does "photo" signify in this context?

• Food

• Light

• Plant

• Energy

What is the role of plants in the broader ecosystem's food chain?

• They are consumers, eating other organisms.

• They are decomposers, breaking down dead matter.

• They are the foundation, producing their own food.

• They are secondary consumers, eating herbivores.

What is the primary form of energy produced during the light reactions of photosynthesis?

• Glucose and oxygen

• G3P (glucose precursor)

• ATP and NADPH

• Carbon dioxide and water

Photosynthesis is divided into two main stages. What are these stages called?

• Glycolysis and Krebs Cycle

• Light Reactions and the Calvin Cycle

• Electron Transport Chain and Oxidative Phosphorylation

• Carbon Fixation and Reduction

What is the main purpose of the Calvin Cycle in photosynthesis?

• To convert solar energy into chemical energy.

• To produce oxygen from water.

• To build glucose precursors using chemical energy.

• To break down glucose for energy.

In which organelle within plant cells does photosynthesis take place?

• Mitochondrion

• Nucleus

• Vacuole

• Chloroplast

What is the fluid-filled space surrounding the thylakoids within a chloroplast, where the calvin cycle occurs called?

• Cytoplasm

• Lumen

• Stroma

• Nucleoid

What are the stacks of thylakoids within a chloroplast referred to as?

• Stroma

• Grana

• Plastoglobulus

• Ribosomes
