C1.3 Photosynthesis

Chlorophyll

• A green pigment responsible for the absorption of light to provide energy for photosynthesis.

• A type of carbohydrate that stores energy in plants.

• A protein that helps in the synthesis of DNA.

• A mineral that aids in the growth of plants.

Light intensity

• The amount of light emitted by a source.

• The level of light received on a plant surface.

• The color of light that plants absorb.

• The duration of light exposure to plants.

Photosystem II

• The first protein complex in the light-dependent reactions of oxygenic photosynthesis.

• A pigment that absorbs light energy during photosynthesis.

• The site of carbon fixation in the Calvin cycle.

• A type of chlorophyll found in plants.

Data logger

• An electronic device that records data over time.

• A device used for measuring temperature only.

• A tool for analyzing data in real-time.

• A software application for data visualization.

Chloroplasts

• Organelles found in plant cells and eukaryotic algae that conduct photosynthesis.

• Structures that provide support and rigidity to plant cells.

• Cellular components responsible for cellular respiration.

• Organelles that store genetic information in eukaryotic cells.

Quantum mechanics

• A fundamental theory in physics describing the properties of nature on an atomic scale.

• A theory that explains the motion of planets in the solar system.

• A branch of physics that deals with macroscopic objects and their interactions.

• A method of predicting weather patterns based on atmospheric data.

Pigment

• A substance that gives color to tissues or cells.

• A type of protein found in muscles.

• A chemical that causes a reaction in the body.

• A mineral that strengthens bones.

FACE (free-air carbon dioxide experiments)

• Experiments that study the effects of elevated carbon dioxide levels on plants in their natural environment.

• Experiments that measure the impact of soil nutrients on plant growth.

• Experiments that analyze the effects of temperature changes on plant photosynthesis.

• Experiments that investigate the role of water availability in plant development.

Photosystem I

• A protein complex that uses light energy to produce the high energy carriers ATP and NADPH.

• A structure that absorbs carbon dioxide during photosynthesis.

• A type of chlorophyll molecule that reflects green light.

• An enzyme that catalyzes the breakdown of glucose.

Wavelengths

• The distance between two consecutive peaks (or troughs) of a light wave.

• The speed of light in a vacuum.

• The frequency of a light wave measured in hertz.

• The intensity of light measured in lumens.
