Photosynthesis and Respiration in Plants

These flashcards cover key concepts related to plant respiration and photosynthesis based on experiments with different light exposures.

Photosynthesis

The process by which green plants use sunlight to synthesize foods with the help of chlorophyll.

Respiration in Plants

The process by which plants convert glucose and oxygen into energy, releasing carbon dioxide and water as byproducts.

Oxygen Displacement

The increase in water level in a tube due to the production of oxygen during photosynthesis.

pH Indicator (Phenol Red)

A chemical indicator used to determine acidity or alkalinity, turning yellow in acidic conditions and red in neutral or alkaline conditions.

Effect of Light on Plant Growth

Plants exposed to light will undergo photosynthesis and use CO2, affecting the movement of water and the color change in pH indicators.

Green Light Absorption in Plants

Plants do not effectively use green light for photosynthesis, leading to distinct behaviors compared to those exposed to white light.

Aluminum Foil Effect on Plants

Plants covered in aluminum foil are deprived of light, leading them to use oxygen and produce CO2, affecting solution movement and pH.

Solution Movement in Tubes

The movement of the liquid in tubes connected to plants indicative of respiratory or photosynthetic activity.
