Are sapwood and xylem the same?
No, sapwood and xylem are not the same. Sapwood is the outermost layer of wood in a tree that transports water and nutrients, while xylem is a type of vascular tissue within the tree that transports water and nutrients from the roots to the rest of the plant. Sapwood is composed of xylem cells, but xylem also includes other types of cells such as vessels and fibers.
What occurs if oxygen is absent during the second stage of cellular respiration?
If oxygen is not available during the second stage: the glucose (now pyruvate molecule, after glycolysis) the pyruvate can not enter the mitochondrial membrane so it takes an alternative method of producing ATP
Other organisms can continue 'cellular respiration' with out the need of O2 (anaerobic method) such as:
•Yeast
i) Alcohol fermentation
•Human Muscle cells
i) Produces lactic acid, which makes your muscles sore
How many ATP are produced from Calvin cycle?
The Calvin cycle does not directly produce ATP. However, ATP is required as an energy source for the Calvin cycle to function. ATP is typically generated through the light-dependent reactions of photosynthesis.
What does light carbon dioxide and water make?
Light, carbon dioxide, and water are the essential components needed for photosynthesis, a process by which plants and other organisms produce oxygen and glucose (sugar) as a result. Light energy is absorbed by chlorophyll in plants, which converts carbon dioxide (CO2) and water (H2O) into glucose (C6H12O6) and oxygen (O2).
What is a change in the way a plant grows in response to sunlight?
Phototropism is the change in the way a plant grows in response to sunlight. This process involves the plant bending towards the light source to optimize its exposure to sunlight for photosynthesis.
What explains the sequence of energy transformations during photosynthesis?
During photosynthesis, light energy is absorbed by chlorophyll in the chloroplasts and converted into chemical energy in the form of ATP and NADPH through the light-dependent reactions. This chemical energy is then used in the light-independent reactions (Calvin cycle) to convert carbon dioxide and water into glucose, a high-energy molecule that can be used by the plant for growth and metabolism.
State five essential conditions needed for photosynthesis to take place?
The five essential conditions needed for photosynthesis to take place are sunlight, carbon dioxide, water, chlorophyll, and enzymes. Without any of these conditions, photosynthesis cannot occur effectively.
What are the many unanswered questions of photosynthesis?
Use the search tool in the upper right (the magnifying glass) and you might find some. Narrow your search category down when looking for questions (botany, for example, and I'm not sure but there MIGHT very well be a category for photosynthesis.
What captures the energy from sunlight and converts into chemical energy?
Chlorophyll is the pigment that captures sunlight in plants and algae. Through the process of photosynthesis, chlorophyll converts this light energy into chemical energy in the form of glucose and other carbohydrates.
Does sunlight have to be absorbed by plants before photosynthesis can take place?
Yes, sunlight needs to be absorbed by chlorophyll in plant cells for photosynthesis to occur. Chlorophyll captures the energy from sunlight, which is then used to convert carbon dioxide and water into glucose and oxygen.
What is needed for starch production in a leaf?
Starch production in a leaf requires three main components: sunlight, carbon dioxide, and water. Through the process of photosynthesis, green plants use these elements to convert light energy into chemical energy stored in starch molecules. This starch can then be stored and used later as an energy source for the plant.
Transport tissue that conducts various substances up and down the plant are?
The transport tissue that conducts water and dissolved minerals from roots to leaves is xylem. The tissue that transports sugars and other organic compounds from leaves to other parts of the plant is phloem. These tissues together play a crucial role in the overall functioning and growth of a plant.
Photosynthesis occurs best at wavelenths that are?
Photosynthesis occurs best at wavelengths of light that correspond to the blue (around 450 nm) and red (around 650 nm) regions of the electromagnetic spectrum. These wavelengths are absorbed most efficiently by chlorophyll, the pigment responsible for capturing light energy during photosynthesis.
Root cells obtain oxygen from the air spaces in the soil through diffusion and release carbon dioxide as a byproduct of cellular respiration. This process occurs in the mitochondria of root cells and helps produce energy for growth and other metabolic activities. Oxygen uptake and carbon dioxide release happen in the roots as part of their respiration process.
What happens when you cover the leaf of potted plant with strip of black paper?
We did this experiment and honestly didn't notice much of a difference in the leaves. I think what is supposed to happen is that the leaf should start to lose it's green color and wilt because it cannot photosynthesize.
Before fats can be metabolized in aerobic cellular respiration they must be converted to?
Fats must be converted to fatty acids and glycerol before they can be metabolized in aerobic cellular respiration. This breakdown process occurs in the cytoplasm of the cell through a series of enzymatic reactions. Once converted, fatty acids can enter the mitochondria to undergo beta-oxidation and produce acetyl-CoA for the citric acid cycle.
How does the source of energy for photosynthesis nd respiration differ?
The source of energy for photosynthesis is sunlight, which is converted into chemical energy in the form of glucose. In contrast, the source of energy for cellular respiration is glucose, which is broken down to release chemical energy in the form of ATP.
Yes, plants rely on photosynthesis to produce energy in the form of glucose, which is then converted into starch for storage. Without photosynthesis, the plant cannot generate glucose, leading to a depletion in energy reserves for essential processes.
What the importance of the food that produced by plants during photosynthesis to animals?
Well, without photosynthesis, the plants would not have energy for building their bodies. So with a little exagerration, it could be said that photosynthesis is building up the plants, which represent carbohydrates and other molecules needed by animals.
Which steps in aerobic cellular respiration require oxygen?
The citric acid cycle and the electron transport chain are the steps in aerobic cellular respiration that require oxygen. Oxygen is the final electron acceptor in the electron transport chain, where it helps generate ATP by facilitating the transfer of electrons from NADH and FADH2 to oxygen.
What air do plants need to do photosynthesis?
Plants take carbon dioxide from the air and use it in a action called photosynthisis in which the plant makes food and energy. When phtosynthisis is completed plants expell oxygen.
How do photosynthesis and respiration affect the carbon dioxide oxygen cycle?
plants during photosynthesis take in carbon dioxide and give out oxygen while animals during respiration breathe in oxygen and breathe out carbon dioxide making a complete continuous cycle.
Carbon dioxide-oxygen chemical equation?
If you mean Carbon minus Oxygen then, no. It isn't an equation.
What delivers water to the leaf in a plant?
Water is delivered to the leaf in a plant through the xylem vessels, which transport water and nutrients from the roots up to the leaves. This process is known as transpiration, where water is pulled up through the plant due to the evaporation of water from the leaf's surface, creating a negative pressure that helps move water upwards.
