What else can I help you with?
What could you look for in a coleus leaf to determine if photosynthesis is occurring?
You could look for the presence of chlorophyll, which is necessary for photosynthesis to occur. Additionally, you could observe if the leaf is green and healthy-looking, as plants that are actively carrying out photosynthesis tend to have vibrant foliage. Finally, you could check for the production of oxygen bubbles through a simple experiment to confirm the occurrence of photosynthesis.
Why is it necessary to leave the green leaf tube in the dark?
Leaving the green leaf tube in the dark is necessary to prevent photosynthesis from occurring. In the absence of light, the plant cannot produce glucose or oxygen through photosynthesis, allowing for the assessment of the plant's stored starch. This helps to demonstrate the role of light in photosynthesis and the importance of chlorophyll in capturing light energy. Additionally, it ensures that any changes observed in the leaf are solely due to the absence of light rather than ongoing photosynthetic activity.
What is a central metal chlorophyll natural occurring chelate compound?
magnesium
How many electrons does the heaviest naturally occurring element have?
Uranium, number 92 is the last of the naturally occurring elements and, of course, it has 92 electrons.
What is a pigment that traps uv radiation?
A pigment that traps UV radiation is melanin. Melanin is a naturally occurring pigment found in the skin, hair, and eyes of humans and animals. It helps to absorb and dissipate UV radiation to protect underlying skin cells from damage.
Why does photosynthesis not occur when chlorophyll water and carbon dioxide are placed in a test tube in the sunlight?
Photosynthesis requires not only chlorophyll, water, and carbon dioxide but also specific conditions such as the presence of light energy in a suitable form and a proper cellular environment. In a test tube, the lack of a structured cellular environment prevents the necessary biochemical processes from occurring. Additionally, without the complex interactions found in living plant cells, such as enzyme activity and the transport of materials, photosynthesis cannot proceed effectively, even in sunlight. Thus, while the basic components are present, the overall conditions for photosynthesis are not met.
Is photosynthesis performed by all plants?
All plants that HAVE CHLOROPHYLL. Most plants that have chlorophyll are green. Photosynthesis is when H20 and C02 is taken in from a plant and using the energy of the sun, turn it into glucose (C6 H12 O6), which is used as food in plants. Most of the photosynthesis occurring in the plant happens in the leaves. When glucose is created, then phloem (vascular tissue located in the stem) carries it to other places in the plant, thus powering the whole plant.
What process is occurring more in a plant that is being supplied with sunlight?
Photosynthesis.
What process occurring in green plants gives off CO2?
Photosynthesis is the process
Where in the plant cell is the Calvin cycles occurring?
The Calvin cycle, a series of biochemical reactions that occur during photosynthesis, takes place in the stroma of the chloroplast, which is a compartment within the plant cell where photosynthesis occurs.
Which of these is naturally occurring processes is a chemical change?
Two common examples are photosynthesis and cellular respiration.
What is Chloropast?
A plastid containing chlorophyll, developed only in cells exposed to the light. Chloroplasts are minute flattened granules, usually occurring in great numbers in the cytoplasm near the cell wall, and consist of a colorless ground substance saturated with chlorophyll pigments. Under light of varying intensity they exhibit phototactic movements. In animals chloroplasts occur only in certain low forms.Read more: What_is_chloroplast
