Answer:
ans 1) the process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a by-product.
ans 2) Stamens are the male reproductive parts of flowers.
ans 3) Plant hormones are signal molecules produced within plants, that occur in extremely low concentrations. Plant hormones control all aspects of growth and development, from embryogenesis, the regulation of organ size, pathogen defense, stress tolerance and through to reproductive development.
ans 4) Enzymes are macromolecular biological catalysts that accelerate chemical reactions. The molecules upon which enzymes may act are called substrates, and the enzyme converts the substrates into different molecules known as products.
ans 5) he regular movement or sound that the heart makes as it sends blood around your body

Explanation:
Answer:
the process by which green plants turn carbon dioxide and water into food using energy from sunlight
Stamens are the male reproductive parts of flowers. A stamen consists of an anther (which produces pollen) and a filament. The pollen consists of the male reproductive cells; they fertilize ovules.
Plant hormones are signal molecules produced within plants, that occur in extremely low concentrations. Plant hormones control all aspects of growth and development, from embryogenesis, the regulation of organ size, pathogen defense, stress tolerance and through to reproductive development.
Enzymes are proteins that serve as catalysts and reduce the need for specific chemical reactions within a cell.
When the heart is busy with pumping blood, the different chambers of the heart open and close, or contract and relax. Each time the chambers contract or relax, a thumping sound is produced. This is what is known as the heartbeat.
