What is photosynthesis class 6th?

Hint: Photosynthesis is the process by which green plants prepare their own food with the help of carbon-dioxide, water, chlorophyll and light. By this process the light energy is converted into chemical energy.

What is photosynthesis in biology class 9?

Photosynthesis is a physiological process by which plant cells containing chlorophyll produce food in the form of carbohydrates by using carbon dioxide, water and light energy. Oxygen is released as a by-product.

Which is the site of respiration in cell?

While most aerobic respiration (with oxygen) takes place in the cell’s mitochondria, and anaerobic respiration (without oxygen) takes place within the cell’s cytoplasm.Feb 12, 2020

What is the site of light reaction in chloroplast?

thylakoid discs
The light reaction takes place in the thylakoid discs. There, water (H20) is oxidized, and oxygen (O2) is released. The electrons freed up from water are transfered to ATP and NADPH. The dark reaction occurs outside of the thylakoids.Aug 21, 2014

What are the principal site for photosynthesis in plants?

The site of photosynthesis in plants

In land plants, the principal organs of photosynthesis are the leaves (Figure 2A). Leaves have evolved to expose the largest possible area of green tissue to light and entry of CO2 to the leaf is controlled by small holes in the lower epidermis called stomata (Figure 2B).

What are the sites of photosynthesis in eukaryotic cells?

Organelles, called plastids, are the main sites of photosynthesis in eukaryotic cells. Chloroplasts, as well as any other pigment containing cytoplasmic organelles that enables the harvesting and conversion of light and carbon dioxide into food and energy, are plastids.

Where is the specific location of photosynthesis?

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.

In which part of the chloroplast does photosynthesis occur?

Photosynthesis takes place inside the chloroplasts that sit in the mesophyll of the leaves. The thylakoids sit inside the chloroplast and they contain chlorophyll which absorbs the different colours of the light spectrum to create energy (Source: Biology: LibreTexts).

What is the site of photosynthesis in leaves of a plant write the chemical equation involved in photosynthesis?

The process of photosynthesis is commonly written as: 6CO2 + 6H2O → C6H12O6 + 6O2.

Where does photosynthesis take place Byjus?

In the chloroplast. Plants have specific structures unique to them known as chloroplasts. It contains chlorophyll – the most important pigment that drives the photosynthesis process.

What is photosynthesis for kids?

Photosynthesis is the process in which green plants use sunlight to make their own food. … Photosynthesis requires sunlight, chlorophyll, water, and carbon dioxide gas. Chlorophyll is a substance in all green plants, especially in the leaves. Plants take in water from the soil and carbon dioxide from the air.

What is photosynthesis in biology class 11?

Photosynthesis is a process in which the light energy obtained from the sunlight is used in the manufacture of oxygen and sugar molecules in the presence of carbon dioxide and water.

What is photosynthesis in short form?

The definition of photosynthesis is the process through which plants use water and carbon dioxide to create their food, grow and release excess oxygen into the air. … An example of photosynthesis is how plants convert sugar and energy from water, air and sunlight into energy to grow.

What is photosynthesis Class 9 answer?

Photosynthesis is the physico-chemical process by which plants can convert light energy into chemical energy, in the form of carbohydrate from simple inorganic substances like atmospheric carbon dioxide and water. Photosynthesis requires carbon dioxide, sunlight, water and chlorophyll as its basic raw materials.

Where is the cell wall present?

A cell wall is a fairly rigid layer surrounding a cell located outside of the plasma membrane that provides additional support and protection. They are found in bacteria, archaea, fungi, plants, and algae. Animals and most other protists have cell membranes without surrounding cell walls.

What is the site of cellular respiration Brainly?

The mitochondria is the site of energy production i.e. by cellular respiration.

What is the site of stroma?

the chloroplast
Stroma, in botany, refers to the colorless fluid surrounding the grana within the chloroplast. Within the stroma are grana (stacks of thylakoid), and the sub-organelles or daughter cells, where photosynthesis is commenced before the chemical changes are completed in the stroma.

What is the site of the Calvin cycle?

Unlike the light reactions, which take place in the thylakoid membrane, the reactions of the Calvin cycle take place in the stroma (the inner space of chloroplasts).

What is the site of light reaction in chloroplast Class 10?

The light reaction occurs in the thylakoids of the chloroplast. When the light hits, chlorophyll a get excited to higher energy state followed by a series of reactions.

What are the sites of photosynthesis with diagram?

chloroplast is the organelle that is the site of photosynthesis. All green parts of a plant, including green stems and unripened fruit, have chloroplasts, but the leaves are the major sites of photosynthesis in most plants. There are about half a million chloroplasts per square millimeter of leaf surface.

What are the parts of a chloroplast?

List out the different parts of Chloroplast?

  • Stroma.
  • Inner membrane.
  • Outer membrane.
  • Thylakoid membrane.
  • Intermembrane Space.

What is the correct sequence of events during photosynthesis?

The three events that occur during the process of photosynthesis are: (i) Absorption of light energy by chlorophyll. (ii) Conversion of light energy to chemical energy and splitting of water molecules into hydrogen and oxygen. (iii) Reduction of carbon dioxide to carbohydrates.

Why are leaves the major site of photosynthesis?

Leaf is considered to be the best site of Photosynthesis because in a plant the leaves have the maximum surface area and it can perform photosynthesis in a more efficient way as the rate of photosynthesis increases with the increase in the surface area available for photosynthesis.

What is photosynthesis and where does it occur?

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 get carbon dioxide from the air through their leaves, and water from the ground through their roots.

Where does Phase One of photosynthesis occur?

Stage One: Light Reactions

In the light-dependent process, which takes place in the grana, the stacked membrane structure within chloroplasts, the direct energy of light helps the plant to make molecules that carry energy for utilization in the dark phase of photosynthesis.

How many places does photosynthesis take place?

Photosynthesis occurs in chloroplasts found in the leaves and green stems of plants. One leaf has tens of thousands of cells each of which has 40 to 50 chloroplasts. Each chloroplast is divided into many disk-shaped compartments called thylakoids, which are arranged vertically like a stack of pancakes.
