Definition: Describing something that has become sensitive to light, often as a result of a chemical process.

Example: The photosensitized material reacted strongly when exposed to sunlight.

Definition: To make a substance sensitive to light, often used in scientific or medical contexts.

Example: The researchers photosensitized the cells to study their reaction to light exposure.

Definition: A substance that becomes reactive when exposed to light, often used in chemical reactions to produce a desired effect.

Example: The researchers used a photosensitizer to enhance the efficiency of the solar cells.

Definition: The outer layer of a star that gives off light, particularly the sun.

Example: The photosphere of the sun is where sunspots can be observed.

Definition: Relating to the visible surface of a star, especially the sun, where light is emitted.

Example: The photospheric temperature of the sun is about 5,500 degrees Celsius.

Definition: A substance produced by plants during the process of converting sunlight into energy, which is used for growth and development.

Example: The plant stored the photosynthate in its roots for later use.

Definition: The process by which green plants and some other organisms use light to make food from carbon dioxide and water, producing oxygen as a byproduct.

Example: Photosynthesis is essential for life on Earth as it provides oxygen and food for many organisms.

Definition: To carry out the process by which green plants and some other organisms use sunlight to make food from carbon dioxide and water.

Example: Plants can photosynthesize, turning sunlight into energy.

Definition: To create food using sunlight, water, and carbon dioxide, a process mainly done by plants.

Example: Plants can photosynthesize to produce their own food.

Definition: Relating to the process by which green plants and some other organisms use sunlight to make food from carbon dioxide and water.

Example: Plants are photosynthetic organisms that convert sunlight into energy.

Definition: A biochemical system in chloroplasts that plays a key role in the process of converting light energy into chemical energy during photosynthesis.

Example: The photosystem is essential for plants to convert sunlight into energy.

Definition: Relating to the movement of organisms in response to light.

Example: Certain insects are phototactic, moving towards light sources.
