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: A regular cycle of light and darkness that occurs over a specific period, often related to the length of day and night.

Example: Plants use the photoperiod to determine when to flower and grow.

Definition: Relating to the response of organisms to the length of day and night, especially in terms of growth and reproduction.

Example: Many plants are photoperiodic, meaning they flower based on the amount of light they receive each day.

Definition: Relating to vision that occurs in bright light, particularly when the eyes are adapted to such conditions, and primarily involves the cone cells in the retina.

Example: The photopic vision allows us to see colors clearly during the day.

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: This word describes something that tends to move or grow in response to light, often used in relation to plants or organisms that react to light sources.

Example: Plants are phototropic, bending towards the sunlight to maximize their growth.

Definition: The way a plant or organism grows or moves in response to light, usually towards it.

Example: The sunflower exhibits phototropism by turning its head to follow the sun throughout the day.
