The video explains photosynthesis, a process by which plants make food using sunlight, water, and carbon dioxide. It describes how plants absorb water through roots, transport it via xylem and flum, and take in carbon dioxide through stomata. Sunlight is absorbed by chlorophyll in chloroplasts, initiating the chemical reaction that produces glucose and oxygen. The video highlights the interdependence of plants and animals in the oxygen-carbon dioxide cycle.

What do plants absorb from the soil that is essential for photosynthesis?

• Nitrogen

• Oxygen

• Water

• Carbon

What are the names of the tubes in plant roots that help transport water?

• Mesophyll and Cortex

• Epidermis and Cuticle

• Xylem and Phloem

• Stomata and Chloroplast
