Photosynthesis

When carbon dioxide is low in the leaf, the Calvin cycle cannot proceed efficiently due to a lack of substrate. This leads to a decrease in photosynthesis and a buildup of reactants from the light reactions. As a result, the plant's growth and productivity may be limited.

The dark reaction, also known as the Calvin cycle, is a series of biochemical reactions that occur in the stroma of chloroplasts in plants. It uses energy captured during the light-dependent reactions to convert carbon dioxide into sugars like glucose. This process does not require light and is essential for the synthesis of carbohydrates in plants.

Plants need sunlight, water, and carbon dioxide to carry out photosynthesis. These essential components are used by plants to produce glucose, which serves as their primary energy source. Additionally, chlorophyll, a pigment found in plant cells, helps capture sunlight and convert it into energy during the photosynthesis process.

Light, carbon dioxide, and water are the materials needed to start photosynthesis. The carbon dioxide is needed for the Calvin cycle while the light and water are required for the light reactions.

Light dependent reactions produce ATP and NADPH from energy captured from light. Therefore without light it cannot proceed. Light independent reactions fix carbon dioxide into glucose using the ATP and NADPH produced in the light dependent reactions. So light independent reactions can occur without light as long as CO2, ATP and NADPH is present.

In the light-dependent cycle of photosynthesis, reactants such as water and light energy are converted into products such as oxygen, ATP, and NADPH through a series of complex reactions involving photosystems I and II, electron transport chains, and ATP synthase. These chemical transformations are essential for capturing and converting light energy into chemical energy that can be used in the Calvin cycle to produce glucose.

Six factors that affect photosynthesis are light intensity, temperature, carbon dioxide concentration, water availability, chlorophyll concentration, and nutrients. Changes in any of these factors can impact the rate of photosynthesis in plants.

The light-dependent reactions of photosynthesis occur in the thylakoid membranes of chloroplasts. This is where chlorophyll and other pigments absorb light energy and convert it into chemical energy in the form of ATP and NADPH. This energy is then used in the light-independent reactions to produce glucose.

About 75-80% of the energy captured through photosynthesis in a plant ends up being stored as starch in the kernel. This starch serves as a source of energy for the plant and can be utilized for growth and reproduction.

Chlorophyll is essential to photosynthesis because it traps the needed sunlight energy for the process. It absorbs light energy from the sun and converts it into chemical energy that is used to drive the synthesis of organic compounds in plants.

Plants get CO2 by gaseous exchange, water from the soil, and required energy by photolysis of water to make sugar.

Photosynthesis occurs in the organelles called chloroplasts which hold chlorophyll.

Plants need sunlight, water and nutrients to grow. Herbivores eat the plants, carnivores eat the herbivores, omnivores (like humans) eat plants and animals. Therefore if plants stopped existing, the whole food chain would collapse and all life die out. In such a scenario, if we could artificially manufacture and grow food to feed ourselves, then we might survive.

There are two materials. They are CO2 and water

Glucose is the sugar produced during photosynthesis. It is a simple carbohydrate that serves as the primary source of energy for the plant and is also used as a building block for more complex carbohydrates like starch.

The chloroplasts in the cells of the leaves are responsible for performing photosynthesis in plants. The chloroplasts contain chlorophyll, a pigment that absorbs light energy and converts it into glucose through a series of chemical reactions.
