What is photosynthesis biology question?

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.

How does photosynthesis work AP Bio?

AP Biology 🧬 Photosynthesis is a chemical process with the following equation: H2O + CO2 → C6H12O6 + O2. Both plants and photosynthetic bacteria are capable of this complex conversion process. The overall reaction is spurred by the energy from a photon of light striking a pigment in the chloroplast.

What is photosynthesis Q answer?

Photosynthesis is a process by which phototrophs convert light energy into chemical energy, which is later used to fuel cellular activities. The chemical energy is stored in the form of sugars, which are created from water and carbon dioxide.

What is a good hypothesis for photosynthesis?

Research Question and Hypothesis Hypothesis: Yes, light intensity does affect the rate of photosynthesis. Too much light may cause plants to “burn out” while too little light will not provide enough light for optimal photosynthesis activity.

Why can photosynthesis not occur at very high temperatures?

At higher temperatures, the enzymes simply do not operate and get denatured. This is even after the increase of carbon dioxide diffusion into the leaves. The rate of photosynthesis at lower temperatures is restricted by the number of molecular collisions taking place between the substrate and the enzymes.

What is Kranz anatomy differentiate C3 and C4 cycle?

The leaves possess kranz anatomy, and the chloroplasts of these plants are dimorphic….C3 vs C4 Plants.

C3 Plants C4 Plants
Leaves of these plants DO NOT show Kranz anatomy. Leaves of these plants show Kranz anatomy.
C3 Plants are common in temperate climates. C4 plants are common in tropical climates.

Is photosynthesis endothermic or exothermic?

endothermic reaction
Photosynthesis requires energy to drive the chemical reaction. Photosynthesis is an endothermic reaction. This means it cannot occur without energy (from the Sun). The light required is absorbed by a green pigment called chlorophyll in the leaves.

How is ATP used in photosynthesis?

ATP can be used to store energy for future reactions or be withdrawn to pay for reactions when energy is required by the cell. Animals store the energy obtained from the breakdown of food as ATP. Likewise, plants capture and store the energy they derive from light during photosynthesis in ATP molecules.

What is photosynthesis MCQS?

MCQ on Photosynthesis Photosynthesis is the process by which plants, algae and some bacteria use sunlight, carbon dioxide and water to prepare their food. This is a biogeochemical process in which light energy is converted into chemical energy. Photosynthesis takes place in the chloroplast.

Why photosynthesis is called dark reaction?

Instead, dark reaction uses ATP and NADPH to produce energy molecules. No photosystem is required. Photolysis of water does not occur. So, the dark reaction in photosynthesis is called so because it does not require light energy.

What is the purpose of photosynthesis?

It is the number one source of oxygen in the atmosphere.

  • It contributes to the carbon cycle between the earth,the oceans,plants and animals.
  • It contributes to the symbiotic relationship between plants,humans and animals.
  • It directly or indirectly affects most life on Earth.
  • What is the biology of photosynthesis?

    It has been published in the journal The Plant Cell . During photosynthesis, plants use sunlight to convert carbon dioxide and water into carbohydrates and oxygen. They take up the carbon dioxide from the ambient air through stomata on the surface of their leaves. At very warm temperatures, however, these close to prevent excessive water loss.
