Exam: GRE (Verbal)

Definition: A type of organism that can make its own food using light energy and inorganic materials. Examples include green plants and certain bacteria that perform photosynthesis.

Example: Green plants are photoautotrophs because they use sunlight to create their own food.

Definition: Relating to the study of how light affects living organisms.

Example: The photobiological effects of sunlight on plants are crucial for their growth.

Definition: A scientist who studies the effects of light on living organisms and biological processes.

Example: The photobiologist conducted experiments to understand how plants respond to different light conditions.

Definition: The branch of science that studies how light affects living things and their biological processes.

Example: Photobiology helps us understand how plants use sunlight for photosynthesis.

Definition: A type of cathode that produces electrons when it is illuminated by light or other forms of radiant energy.

Example: The photocathode is essential in devices like photomultiplier tubes, where it converts light into an electrical signal.

Definition: Relating to the chemical processes that occur when light interacts with substances.

Example: The photochemical reactions in plants are essential for photosynthesis.

Definition: In a way that relates to the chemical reactions caused by light.

Example: The plants grow photochemically, using sunlight to convert carbon dioxide into oxygen.

Definition: A scientist who studies the chemical effects of light and how it interacts with different substances.

Example: The photochemist conducted experiments to understand how sunlight affects plant growth.

Definition: A branch of science that studies how light affects chemical reactions and processes.

Example: Photochemistry plays a crucial role in understanding how plants convert sunlight into energy during photosynthesis.

Definition: Relating to a substance that can change color when exposed to light.
