Apr 4, 2022 · Photosynthesis is a chemical process in green plants. In it light energy is converted into chemical energy. Plants use energy from light to combine water (H 2 O) and carbon dioxide (CO 2). The products of this reaction are simple carbohydrates and oxygen (O 2). An example of a simple carbohydrate is glucose.
Aug 27, 2024 · Uses of Light Energy 1. Photosynthesis. Photosynthesis is a process used by plants, algae, and some bacteria to convert light energy into chemical energy. This process is essential for the production of oxygen and glucose, which are vital for the survival of most life forms on Earth. 2. Vision. Light energy enables vision in humans and animals.
- Light. Plants usually get the light they need from the Sun. But they can also grow in artificial light. Plants use light energy to make a type of sugar called glucose.
- Air. Air contains many gases. They include nitrogen, oxygen, carbon dioxide and water vapour. Graph - Text Version. Air is made up of approximately 78 percent nitrogen, 21 percent oxygen, one percent argon and 0.038 carbon dioxide.
- Water. Plants need water for photosynthesis. Absorbed by the roots, water travels through a plant’s stems to the chloroplasts in the leaves. Water also helps move nutrients from the soil into the plant.
- Nutrients. Nutrients are substances that nourish a plant. In particular, plants need nitrogen, phosphorus and potassium. When dissolved in water, these nutrients get absorbed by a plant’s roots.
Nov 13, 2024 · In chemical terms, photosynthesis is a light-energized oxidation–reduction process. (Oxidation refers to the removal of electrons from a molecule; reduction refers to the gain of electrons by a molecule.) In plant photosynthesis, the energy of light is used to drive the oxidation of water (H 2 O), producing oxygen gas (O 2), hydrogen ions (H ...
- Photosynthesis is critical for the existence of the vast majority of life on Earth. It is the way in which virtually all energy in the biosphere be...
- The process of photosynthesis is commonly written as: 6CO2 + 6H2O → C6H12O6 + 6O2. This means that the reactants, six carbon dioxide molecules and...
- The ability to photosynthesize is found in both eukaryotic and prokaryotic organisms. The most well-known examples are plants, as all but a very fe...
Jun 21, 2024 · Most life on Earth depends on photosynthesis.The process is carried out by plants, algae, and some types of bacteria, which capture energy from sunlight to produce oxygen (O 2) and chemical energy stored in glucose (a sugar). Herbivores then obtain this energy by eating plants, and carnivores obtain it by eating herbivores.
Sep 21, 2021 · Generating an Energy Carrier: ATP. In the light-dependent reactions, energy absorbed by sunlight is stored by two types of energy-carrier molecules: ATP and NADPH. The energy that these molecules carry is stored in a bond that holds a single atom to the molecule. For ATP, it is a phosphate atom, and for NADPH, it is a hydrogen atom.

The slats in Fig 4.2.9 include above-ground and below-ground resources. Changes in the availability of resources above- or below-ground will influence plant investment in growth in these areas. Scientists discuss the balance of above- and below-ground growth in terms of the root-to-shoot ratio, abbreviated root:shoot.
