Where does photosynthesis occur in algae?
The photosynthetic process in plants and algae occurs in small organelles known as chloroplasts that are located inside cells.
What is the site of photosynthesis in a green plant?
In plants , photosynthesis takes place in chloroplasts, which contain the chlorophyll. Chloroplasts are surrounded by a double membrane and contain a third inner membrane, called the thylakoid membrane, that forms long folds within the organelle.
What is the sites of photosynthesis?
In plants and algae, which developed much later, photosynthesis occurs in a specialized intracellular organelle—the chloroplast. Chloroplasts perform photosynthesis during the daylight hours. The immediate products of photosynthesis , NADPH and ATP, are used by the photosynthetic cells to produce many organic molecules.
Where exactly does photosynthesis take place?
In plants, the process of photosynthesis takes place in the mesophyll of the leaves, inside the chloroplasts. Chloroplasts contain disc-shaped structures called thylakoids, which contain the pigment chlorophyll. Chlorophyll absorbs certain portions of the visible spectrum and captures energy from sunlight.
Does photosynthesis occur in algae?
Plants, algae and cyanobacteria all conduct oxygenic photosynthesis 1,14. That means they require carbon dioxide, water, and sunlight (solar energy is collected by chlorophyll A). Photosynthesis uses water, carbon dioxide and sunlight to produce energy and oxygen.
Can LED lights cause algae?
LED aquarium lights are not any more likely to cause algae growth than fluorescent bulbs, with some hobbyists even convinced that an LED bulb will actually discourage algae growth. The general ‘ algae ‘ rule is if the intensity is too high, algae will soon start creeping from the edges of your fish tank.
What is the site of respiration?
The enzymatic reactions of cellular respiration begin in the cytoplasm, but most of the reactions occur in the mitochondria. Cellular respiration occurs in the double-membrane organelle called the mitochondrion.
What is the site of photosynthesis short answer?
Photosynthesis occurs within organelles called the chloroplasts that are abundant on the leaf of a plant, giving it its signature green pigment. Of course, the leaf is not the only photosynthetic part of the plant; it’s just where most of it happen most of the time.
What is the site of photosynthesis in green plants Class 7?
Chloroplast is the site of photosynthesis . Carbohydrate is used as food and oxygen is emitted out to atmosphere. This whole process of making food by plants is called photosynthesis . Carbohydrate which is produced in the process of photosynthesis is ultimately converted into starch and stored in leaves.
What process requires oxygen?
Cellular respiration takes in food and uses it to create ATP, a chemical which the cell uses for energy. Usually, this process uses oxygen , and is called aerobic respiration.
Which organelle is only found in plant cells?
A chloroplast is an organelle that is only present in plant cells. It is a plastid that contains chlorophyll and is also where photosynthesis takes place.
Do plants breathe at night?
Plants give out carbon dioxide not only at night but during the day too. It happens because of the process of respiration in which plants take in oxygen and give out carbon dioxide. As soon as the sun rises another process called photosynthesis starts, in which carbon dioxide is taken in and oxygen is given out.
Does photosynthesis produce ATP?
The Light Reactions of Photosynthesis . Light is absorbed and the energy is used to drive electrons from water to generate NADPH and to drive protons across a membrane. These protons return through ATP synthase to make ATP .
Does photosynthesis occur in all plant cells?
Photosynthesis takes place inside plant cells in small objects called chloroplasts . Chloroplasts contain a green substance called chlorophyll . This absorbs the light energy needed to make photosynthesis happen . Plants and algae can only carry out photosynthesis in the light.
What is the formula for photosynthesis?
The process of photosynthesis is commonly written as: 6CO2 + 6H2O → C6H12O6 + 6O2. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.
