What do plants must have for photosynthesis?

Photosynthesis is the process by which plants turn light and carbon dioxide (CO2) into Sugar and Oxygen. Therefore in order for plants to photosynthesize they must have light and carbon dioxide. During the day or in the presence of light, plants are performing 2 processes: Photosynthesis and Cellular Respiration. At night, or when a plant gets no light they only perform cellular respiration. During cellular respiration only, CO2 concentration increases because it is not being used by photosynthesis.

What organelle in plants which is directly responsible for photosynthesis is?

Chloroplasts are the organelles in plants that are directly responsible for photosynthesis. They contain chlorophyll, a pigment that captures sunlight and converts it into chemical energy through the process of photosynthesis.

Why don't water lillies grow very well in moving water?

Water lilies do not grow well in moving water because the constant flow can damage their delicate roots and leaves. They thrive in calm, still waters where they can anchor themselves and receive enough sunlight to grow and bloom successfully. The turbulent conditions of moving water can also dislodge the plants and prevent them from establishing a stable root system.

How are photosynthesis and aerobic cellular respiration?

Aerobic respiration:

C6H12O6 + 6O2 --> 6CO2 + 6H2O

glucose + oxygen produce carbon dioxide and water

Photosynthesis:

6CO2 + 6H2O --> C6H12O6 + 6O2

carbon dioxide and water produce glucose and oxygen

The reactants of aerobic respiration are the products of photosynthesis. Organisms that undergo aerobic respiration need the products of photosynthesis to survive (this includes the plants and other photosynthesizing organisms themselves). Plants and other photosynthesizing organisms need the products of aerobic respiration in order to survive.

Oxygen is given off during which biochemical process?

Oxygen is given off during the process of photosynthesis, where plants, algae, and some bacteria convert carbon dioxide and water into glucose and oxygen using sunlight.

What part of a cell uses cellular rspiration to release energy stored in food?

The mitochondria is the organelle in a cell that uses cellular respiration to release energy stored in food molecules, such as glucose. It is often referred to as the powerhouse of the cell due to its role in producing adenosine triphosphate (ATP), the cell's main energy source.

During photosynthesis a green plant uses what energy from the sun to produce what energy?

A green plant uses light energy from the sun to produce chemical energy in the form of glucose through the process of photosynthesis.

Which gas is evolved during photosynthesis?

Oxygen gas is evolved during photosynthesis as a byproduct of the light-dependent reactions in the chloroplasts of plant cells.

What is the effect of photosynthesis upon the Earth?

without light Plants would not be able to produce starch and we would all starve to death or choke on the co2

without light plants would not be able to produce starch and we would all die

Name given to photosynthesis using organisms?

plants maybe

They are called photo autotrophs. They obtain light energy and carbon from CO2

Do the of photosynthesis ocdark reactions cur only at night?

No, the dark reactions of photosynthesis (Calvin cycle) can occur during the day as well. These reactions do not require light directly, but they depend on the products of the light reactions to proceed. The dark reactions convert CO2 into glucose using ATP and NADPH generated during the light reactions.

How are photosynthesis and cellular respiration reactions in dynamic equilibrium?

Photosynthesis and cellular respiration are interconnected as the products of one process are utilized as reactants in the other. They are not in a static equilibrium but rather a dynamic equilibrium where they continuously occur simultaneously to maintain a balance in the availability of energy and nutrients in the ecosystem. This balance ensures the cycling of carbon and energy between producers and consumers in the environment.

What does NADPH add to the Calvin-Benson cycle?

NADPH serves as a reducing agent in the Calvin-Benson cycle, providing electrons to drive the conversion of 3-phosphoglycerate into glyceraldehyde-3-phosphate. This reduction step ultimately leads to the production of glucose during photosynthesis.

Name two environmental conditions that may effect the rate of photosynthesis?

Light intensity and temperature are two environmental conditions that can affect the rate of photosynthesis. Higher light intensity generally increases the rate of photosynthesis, while extreme temperatures can either inhibit or denature the enzymes involved in the process.

How are sunlight water and carbon dioxide significant in the process of photosynthesis?

Water is needed for all living things, so plants aswell. Carbon Dioxide is like the plants Oxygen. But, for photosynthesis to occur, the plant needs to have a green surface(chlorophylls) and sunlight. Sunlight is needed because for every reaction, you need and activation energy. This time it's light. :)

What is the formula for photosynthysis?

The formulas for photosynthesis are:

In the light phase,,

  • 4H2O-chlorofil--sunlight-------->4H+ +4OH-
  • 4OH---4e--------> 4OH
  • 4OH----->2H2O+O2
  • NADP++e- +H+----->NADPH2(NADPH+H+)
  • ADP+Pi------>ATP

In theDark Phase,,

  • 6CO2+6RuBP--RuBiscko--->12PGA
  • 12PGA+12ATP--->12DPGA+12ADP
  • 12DPGA--->12PGAld
  • 10PGAld---.ineer compound--->6RuBP
  • 2PGAld-----> FDP---->C6H12O6

External respiration involves the use of oxygen to release energy stored in nutrient molecules such as glucose that true or false?

True. External respiration refers to the process where oxygen is taken up from the environment and used to break down nutrient molecules, such as glucose, to release energy in the form of ATP through cellular respiration.

What trap solar energy in photosynthesis?

Chlorophyll molecules trap solar energy during photosynthesis. These pigments are located in the chloroplasts of plant cells and absorb sunlight to initiate the process of converting carbon dioxide and water into glucose and oxygen. Chlorophyll molecules capture light energy through their structure, specifically by absorbing certain wavelengths of light.

Do plants only respire at night?

they breath all the time like us, beacuse if they did not breath through the night they would die.................................................................................. this is wat i am saying i dont no if it is true

How deos a terrarium aid the photosynthesis process?

A terrarium aids the photosynthesis process by providing a controlled environment with ample sunlight, carbon dioxide, and moisture for the plants inside to thrive. The enclosed space helps to retain heat and humidity, creating an ideal microclimate for plant growth and photosynthesis to occur efficiently. Additionally, the transparent walls of the terrarium allow sunlight to penetrate and nourish the plants.

Plant cells need energy in glucose that is released by?

photosynthesis, a process in which plants use sunlight to convert carbon dioxide and water into glucose and oxygen. The glucose produced during photosynthesis serves as the primary energy source for plant cells.

At which temperature would plants most likely use the greatest amount of carbon dioxide?

Plants are likely to use the greatest amount of carbon dioxide at temperatures around 25-30 degrees Celsius, as this is when their metabolic processes are most active. Cooler temperatures can slow down plant metabolism and reduce carbon dioxide uptake, while excessive heat can stress the plants and reduce their ability to photosynthesize efficiently.

Ten raw materials and final goods?

Raw materials: iron ore, cotton, wheat, crude oil, timber, coal, rubber, sugar cane, bauxite, soybeans.

Final goods: smartphones, cars, bread, gasoline, furniture, tires, sugar, aluminum cans, soy milk, paper towels.

Plants use these to turn sunlight energy into chemical energy?

Plants use chlorophyll, a pigment found in chloroplasts, to capture sunlight energy in a process called photosynthesis. This energy is then used to convert carbon dioxide and water into glucose, a form of chemical energy that the plant can use for growth and survival.
