What are substances needed for photosynthesis? what are substances produce during photosynthesis?

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.

Explanation:

It needs:

SUNLIGHT:

Light is important. Sunlight provides the energy needed for photosynthesis to take place.

CHLOROPHYLL:

Its the green pigment in plants

WATER:

The plants absorbs Moisture in the air or when it rains or when its watered.

SOIL:

Soil is needed to fix the plant. It also gives minerals and nutrients. Plants prevent soil erosion. Some plants even grow in water without soil.

C02:

It the gas required for the process. It is one of the most important gases on the earth because plants use it to produce carbohydrates in the process.

The products are:

Oxygen:

Used by animals, plants, humans and all living organisms. Oxygen fuels our cells and helps provide the basic building blocks that our bodies need to survive. Every day, about seven hundred billion cells in our bodies wear out and must be replaced. Without oxygen, our bodies cannot build these new cells. Oxygen is also a particularly important part of our immune system.

Glucose:

Its the plants food used for energy in the form of a sugar.

desert perennials often survive by remaining dormant during dry periods of the year, then springing to life when water becomes available. most annual desert plants germinate only after heavy seasonal rain, then complete their reproductive cycle very quickly.
