What is photosynthesis question and answer?
Answer: Photosynthesis is the process in which green plants use sunlight to make their own food. Photosynthesis requires sunlight, chlorophyll, water, and carbon dioxide gas as raw materials.
What are the 4 requirements for photosynthesis?
The conditions required for photosynthesis are water, sunlight, carbon dioxide and chlorophyll.
Which part of tree is most ideal for photosynthesis?
Photosynthesis and the Leaf In plants, photosynthesis generally takes place in leaves, which consist of several layers of cells. The process of photosynthesis occurs in a middle layer called the mesophyll.
What creates photosynthesis?
Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.
What Colour is chlorophyll?
green color
Chlorophyll is a pigment that gives plants their green color, and it helps plants create their own food through photosynthesis.
What is the final output of photosynthesis?
Glucose and Oxygen are the main output of photosynthesis while Carbon dioxide and Water are the main output of cell respiration. Though the final product of photosynthesis is glucose, the glucose is conveniently stored as starch. It absorbs light. 6CO2 + 6H2O + light energy >>> C6H12O6 + 6O2.
Why are plants green?
The longer answer lies in the details of photosynthesis, the electromagnetic spectrum, energy and “special pairs” of chlorophyll molecules in each plant cell. As such, plants look green because they absorb red light most efficiently and the green light is reflected.
Is photosynthesis fast or slow?
Well, the rate of photosynthesis is usually faster than respiration, so a plant produces more oxygen than it needs for itself. It also produces more sugar than it needs right away, which is how it has some left over to store.
Does photosynthesis occur in dead plants?
Will this affect my investigations into photosynthesis? It is true to say that a leaf will continue to photosynthesise even after it has been removed from the plant, but not for ever. This will prevent the leaf remaining at right angles to the light and therefore result in reduced photosynthesis.
Can photosynthesis occur without chlorophyll?
If plants require chlorophyll to produce energy from sunlight, it’s logical to wonder if photosynthesis without chlorophyll can occur. The answer is yes. Plants that have purplish-red leaves, like Japanese maples, use the photopigments that are available in their leaves for the process of plant photosynthesis.
How fast does photosynthesis occur?
Fast Photosynthesizers In the wild, this species can grow up to 20 inches a day and, under optimal laboratory conditions, can double its size in less than 30 days. For an organism that can grow up to 174 feet high, this is impressive.
