What three things do plants require to use photosynthesis?
Plants require sunlight, water, and carbon dioxide to carry out photosynthesis. Sunlight provides energy for the process, while water and carbon dioxide are used to produce glucose, the plant's main energy source.
Where does photosynthesis occur in lichens?
Photosynthesis in lichens mainly occurs in the green algae or cyanobacteria cells that are part of the lichen structure. These photosynthetic cells are located in the outer layer of the lichen, where they receive light for energy production. The other fungi component of the lichen provides structure and protection for the photosynthetic cells.
How many stages are there in a life cycle of a papaya plant?
young papaya,matured papaya, old papaya with seeds
What do plants do with the oxygen they make from photosynthesis?
The oxygen that plants make is taken up by humans. The humans take the oxygen and transform it into carbon dioxide. When the humans do this then the plants take it and change it back into oxygen. This is a never-ending cycle, without plants, humans and animals would die out, without humans and animals, plants would die out.
What are the 3 things that are needed for photosynthesis?
Typical photosynthesis, ie, the formation of carbohydrates, requires carbon dioxide (from the air), hydrogen (usually from water) and sunshine. Of course a plant with chlorophyll-containing parts is also needed since this is where it all takes place.
Where fat and water and other molecules are stored?
Fat is stored in adipose tissue throughout the body, water is stored in various body compartments such as blood, cells, and extracellular spaces, and other molecules are stored in cells throughout the body for various functions like energy production, structure, and signaling.
What organelle does the light independent reaction occur?
The light-independent reactions of photosynthesis occur in the stroma of the chloroplast, which is a specialized organelle found in plant cells. This is where carbon dioxide is converted into glucose through a series of chemical reactions known as the Calvin cycle.
What plants do not contain chlorophyll?
All plants have chlorophyll. UNLESS these plants have develop parasitic relationships that result in the loss of the chlorophyll producing genes. Off the top of my head indian pipe does not have chlorophyll.
What part of a whale does photosynthesis?
Whales do not perform photosynthesis. Photosynthesis is a process carried out by plants, algae, and some bacteria to convert light energy into chemical energy. Whales are mammals and obtain their energy by consuming food.
Can animals get energy directly from the sun due to photosynthesis?
No, animals cannot perform photosynthesis to directly convert sunlight into energy. Only plants, algae, and some bacteria can carry out photosynthesis. Animals get their energy by consuming plants, other animals, or by breaking down molecules through cellular respiration.
Is photosynthesis the reason the atmosphere is rich in oxygen gas?
Yes, photosynthesis is the primary process responsible for producing oxygen in the atmosphere. During photosynthesis, plants, algae, and some bacteria use sunlight to convert carbon dioxide and water into oxygen and glucose. This oxygen is released into the atmosphere as a byproduct, contributing to the high levels of oxygen present today.
Where does the energy come from that is needed for photosynthesis to occur?
The energy for photosynthesis comes from sunlight. Plants absorb light energy through chlorophyll and use it to convert carbon dioxide and water into glucose and oxygen. This process occurs in the chloroplasts of plant cells.
Where tissue layer is responsible for most of the food production in plants?
The tissue layer responsible for most of the food production in plants is the mesophyll tissue, specifically the palisade mesophyll cells. These cells contain numerous chloroplasts where photosynthesis occurs, converting sunlight into energy for the plant.
Light intensity directly impacts the rate of photosynthesis as it provides the energy needed for the process. Carbon dioxide levels affect the rate by limiting the amount of carbon available for the Calvin cycle, which slows down photosynthesis. Both factors play a crucial role in determining the overall efficiency and productivity of the photosynthetic process.
Unambiguous means clear and not open to interpretation or doubt. It refers to something that is straightforward and easily understood by everyone.
What happens in a photosystem?
In a photosystem, light energy is absorbed by pigments to excite electrons, which then pass through an electron transport chain. This creates a proton gradient across the thylakoid membrane, which drives ATP synthesis. The electrons eventually reduce NADP+ to NADPH, which is used in the Calvin cycle for carbon fixation.
How will a plant with a tip removed grow?
If the tip of a plant is removed, it may stimulate the growth of lateral branches as the plant redistributes its growth hormone auxin to the remaining buds. This can result in bushier growth rather than vertical growth. However, the overall growth of the plant may be stunted depending on how much of the tip was removed and the type of plant.
How might rising global temperatures affect photosynthesis?
Photosynthesis helps reduce Global Warming by taking in carbon dioxide. If there is too much of it, then carbon dioxide keeps the sunlight inside earth's atmosphere making the earth warmer. This leads on to global warming, but photosynthesis helps reduce parts of the effect.
A recent Scientific Article stated that CO2 reclamation could be Adequately Accomplished by the Revisioning of all of Our land use and Agricultural practices.
What is role of potassium ions in photosynthesis?
Potassium ions are important for photosynthesis as they help regulate the opening and closing of stomata, which are small pores on plant leaves that allow for gas exchange. This in turn affects the availability of carbon dioxide for photosynthesis. Potassium ions also play a role in activating enzymes involved in the photosynthetic process.
What are 2 mineral salts used in plants?
Plants need a whole range of mineral nutrients to survive and thrive. They can be split into two main categories, the macronutrients and the micronutrients. The macronutrients are the ones that the plant needs in quite large quantities and the micronutrients are the ones that they need in smaller measurements.
The macronutrients are Nitrogen, Phosphorus, Potassium, Calcium, Magnesium and Sulfur. The first three of which are largely lacking from natural soil and are usually added with fertilizers.
The micronutrients are Boron, Copper, Iron, Chloride, Manganese, Molybdenum and Zinc.
However, the main two nutrients that are required for plants to live are Nitrogen and Potassium.
Why is it important that the processes of respiration and photosynthesis stay in balance?
Respiration and photosynthesis are interconnected processes that rely on each other. Photosynthesis produces oxygen and glucose, which are essential for respiration to occur. Respiration, in turn, produces carbon dioxide needed for photosynthesis. Keeping these processes balanced ensures a stable level of oxygen and carbon dioxide in the atmosphere, which is crucial for the survival of plants, animals, and other organisms.
What protein is produced during photosynthesis?
The protein produced during photosynthesis is called RuBisCO (ribulose-1,5-bisphosphate carboxylase/oxygenase), which plays a key role in fixing carbon dioxide from the atmosphere into organic molecules within the chloroplasts of plant cells.
What is the effect of ATP on the rate of ATP production?
ATP typically inhibits the rate of ATP production by feedback inhibition. When ATP levels are high, the cell slows down its production of ATP to prevent an overaccumulation of the molecule. This helps maintain cellular homeostasis by ensuring that ATP levels remain within a certain range.
What living thing produces sugar in photosynthesis?
Plants use the sun's energy to make sugar. During photosynthesis, chemical energy is stored in the fruits, grains, and vegetables made by the sun's energy. Chemical energy in this case is a food made by the sun. In this whole process, light energy is being converted into chemical energy.
Why are light dependent reactions important to the light independent reaction?
Light-dependent reactions produce ATP and NADPH, which are used as energy sources for the light-independent reactions. These reactions also produce oxygen as a byproduct, which is essential for cellular respiration. Light-independent reactions use the ATP and NADPH produced in the light-dependent reactions to convert carbon dioxide into organic molecules, such as sugars.
