Photosynthesis key terms

controlled variables

Factors that are kept constant during an experiment to ensure that the results are valid.

light intensity

The amount of light energy that is available for photosynthesis, which can affect the rate of the process.

limiting factor

A condition that can restrict the rate of photosynthesis, such as temperature, light intensity, carbon dioxide concentration, or chlorophyll levels.

interaction of factors

The combined effect of multiple variables (temperature, light intensity, carbon dioxide concentration, and chlorophyll) that can influence the rate of photosynthesis.

limiting factor

A condition that can restrict the rate of photosynthesis when it is in short supply, such as light intensity, carbon dioxide concentration, or temperature.

graph interpretation

The process of analyzing graphical representations of data to understand the relationship between variables affecting the rate of photosynthesis.

inverse square law

A principle stating that the intensity of light decreases with the square of the distance from the source, affecting the rate of photosynthesis.

light intensity

The amount of light energy received per unit area, which influences the rate of photosynthesis in plants.

limiting factor

A condition or resource that restricts the rate of a process, such as photosynthesis, when it is in short supply.

cost effectiveness

A measure of how economically a resource, such as heat, light, or carbon dioxide, can be used to enhance plant growth in greenhouses.

glucose

A simple sugar produced during photosynthesis that serves as an energy source for plants and is used in cellular respiration.

respiration

The process by which cells convert glucose and oxygen into energy, carbon dioxide, and water, essential for plant growth and metabolism.

glucose

In Uses of glucose from photosynthesis, glucose refers to a simple sugar produced during photosynthesis that serves as an energy source for plants. This matters in Photosynthesis because it supports the learning objective to explain that glucose produced in photosynthesis may be converted into insoluble starch for storage. Students should use this term accurately when they explain the biology, identify symptoms, or justify an answer in GCSE Biology questions.

starch

In Uses of glucose from photosynthesis, starch refers to an insoluble carbohydrate formed from glucose, used by plants for long-term energy storage. This matters in Photosynthesis because it supports the learning objective to explain that glucose produced in photosynthesis may be converted into insoluble starch for storage. Students should use this term accurately when they explain the biology, identify symptoms, or justify an answer in GCSE Biology questions.

glucose

In Uses of glucose from photosynthesis, glucose refers to a simple sugar produced during photosynthesis that serves as an energy source for plants. This matters in Photosynthesis because it supports the learning objective to explain that glucose produced in photosynthesis may be used to produce fat or oil for storage. Students should use this term accurately when they explain the biology, identify symptoms, or justify an answer in GCSE Biology questions.

fat or oil

In Uses of glucose from photosynthesis, fat or oil refers to substances produced from glucose in plants that serve as energy storage molecules. This matters in Photosynthesis because it supports the learning objective to explain that glucose produced in photosynthesis may be used to produce fat or oil for storage. Students should use this term accurately when they explain the biology, identify symptoms, or justify an answer in GCSE Biology questions.

glucose

In Uses of glucose from photosynthesis, glucose refers to a simple sugar produced during photosynthesis that serves as an energy source for plants. This matters in Photosynthesis because it supports the learning objective to explain that glucose produced in photosynthesis may be used to produce cellulose to strengthen cell walls. Students should use this term accurately when they explain the biology, identify symptoms, or justify an answer in GCSE Biology questions.

cellulose

A complex carbohydrate formed from glucose that provides structural support in plant cell walls.

glucose

A simple sugar produced during photosynthesis that serves as a primary energy source for plants and is a building block for amino acids.

amino acids

Organic compounds that combine to form proteins, which are essential for plant growth and development, synthesized from glucose in plants.

nitrate ions

Essential nutrients absorbed from the soil by plants, necessary for the synthesis of amino acids and proteins.

protein synthesis

The process by which cells use glucose and nitrate ions to produce proteins, which are vital for plant growth and development.

qualitative reagents

Substances used to detect the presence of specific biomolecules, such as starch and glucose, through color changes or other observable reactions.

biomolecules

Organic molecules that are essential for life, including carbohydrates, proteins, and lipids, which can be tested for using qualitative reagents.

glucose

A simple sugar produced during photosynthesis that serves as a primary energy source for plants and is essential for growth and metabolism.

storage

The process by which plants convert excess glucose into insoluble starch for long-term energy storage and structural support.
