Popular Questions About Photosynthesis

What 3 things do you need for photosynthesis?
To perform photosynthesis, plants need three things: carbon dioxide, water, and sunlight. By taking in water (H2O) through the roots, carbon dioxide (CO2) from the air, and light energy from the Sun, plants can perform photosynthesis to make glucose (sugars) and oxygen (O2).
What does photosynthesis start with?
Photosynthesis in plants primarily occurs through its leaves, which are the solar collectors that begin the photosynthetic process. Leaves are covered with a waxy substance called a cuticle that allows them to retain water. Holes called stoma allow carbon dioxide to enter and oxygen to escape.
What is the literal meaning of photosynthesis?
Photosynthesis is a vital process where chloroplast of green plants synthesize sugars by using water and carbon dioxide in the presence of sunlight. Photosynthesis literally means synthesis with the help of light.The green plants carrying out photosynthesis are called autotrophic plant, i.e. they can synthesize their own food.
How does photosynthesis start?
Understanding How Photosynthesis Works. Photosynthesis starts when a photon - a tiny packet of light- is absorbed by a molecule of chlorophyll. The energy of the photon is used to move an electron in the chlorophyll molecule to a higher orbit and that electron moves to another molecule.
