What do you need to know about photosynthesis?
Be careful not to confuse this photosynthesis equation with respiration which is the reverse of this. Photosynthesis requires energy in the form of light to drive the chemical reaction. Photosynthesis is an endothermic reaction. The light energy required is absorbed by a green pigment called chlorophyll in the leaves.
How are carbohydrates made in the process of photosynthesis?
Photosynthesis is the process by which plants make carbohydrates from raw materials, using energy from light.
Why are leaves not tested for glucose in photosynthesis?
Although plants make glucose in photosynthesis, leaves cannot be tested for its presence as the glucose is quickly used, converted into other substances and transported or stored as starch.
How are carbon dioxide and water used in photosynthesis?
Word equation for photosynthesis: carbon dioxide + water chlorophyll sunlight food + oxygen The chlorophyll absorbs the light energy and this energy ensures that the raw materials of carbon dioxide and water combine to form food and oxygen. The food is glucose and is stored as starch in the vacuole of each plant cell.
A level biology photosynthesis. 1. PHOTOSYNTHESIS 12a Bilegdemberel.M. 2. An over view of Photosynthesis • Photosynthesis is a series of reactions in which energy transferred as light is transformed to chemical energy. Energy from light is trapped by chlorophyll, and this energy is then used to i.

Which is part of the two fold process of photosynthesis?
Understand that photosynthesis is a two fold process composed of the light-dependent reactions (i.e., light reactions) and the light independent reactions (i.e. Calvin Cycle or Dark Reactions). Tell where the light reactions and the CO2 fixation reactions occur in the chloroplast. Define chlorophylls giving their basic composition and structure.
Which is the first light dependent reaction in photosynthesis?
Light dependent reaction • The first reactions of photosynthesis require light energy, and are called light dependent reactions. • When light is absorbed by PS I and PS II, electrons in the chlorophyll molecule are boosted to higher energy levels.
