What else can I help you with?
When poured iodine on leaf why it changes?
When iodine is poured on a leaf, the iodine reacts with starch present in the leaf to form a blue-black coloration. Starch is produced in the leaf during photosynthesis and acts as a source of energy for the plant. This reaction allows us to test for the presence of starch in leaves, indicating the plant's ability to produce energy through photosynthesis.
What is the green gooey stuff inside a leaf called?
The green gooey stuff inside a leaf is called chlorophyll. It is a pigment that helps plants absorb sunlight and convert it into energy through the process of photosynthesis.
Why does the part of leaf inside the bottle containing potassium hydroxide solution not get carbon dioxide?
The leaf inside the bottle containing potassium hydroxide solution does not receive carbon dioxide because the potassium hydroxide absorbs the carbon dioxide present in the air. This creates a carbon dioxide-free environment inside the bottle, preventing the leaf from undergoing photosynthesis.
How do carbon dixide get into the leaf?
it gets it by going through the guard cells and stoma
Will a plant still produce oxygen if you pluck off a leaf?
Yes, a plant will continue to produce oxygen after you pluck off a leaf, as the majority of oxygen is produced by the leaves through photosynthesis. The plant will redistribute resources to the remaining leaves to compensate for the removed leaf.
Why is the leaf a site of photosynthesis?
because it has special cells allowingcertain substances in and out.
What pigment is present in certain leaf tissues that allows a leaf to carry on its major function?
The pigment present in certain leaf tissues that allows a leaf to carry on its major function of photosynthesis is chlorophyll. Chlorophyll absorbs light energy from the sun and helps convert it into chemical energy during photosynthesis.
Which substances is used to remove chlorophyll from a green leaf during photosynthesis?
Alcohol, such as ethanol or methanol, is commonly used to remove chlorophyll from a green leaf during photosynthesis. This process is known as leaf decolorization or leaf destarching.
What is the material in the leaf that must be present for photosynthesis to occur?
The material is Chlorophyll and it comes from a green part of a plant cell called the chloroplast.
What substances pass through a leafs stomata?
Water vapor, oxygen, and carbon dioxide pass through a leaf's stomata. Water vapor exits the leaf during transpiration, while carbon dioxide enters the leaf for photosynthesis. Oxygen is a byproduct of photosynthesis and is released from the leaf.
When light energy from the Sun strikes a leaf how is the energy conserved?
When light energy strikes a leaf then chlorophill (a) present in leaf absorb that light energy . By use of that energy photosynthesis occurs.
Which organelles have to be present in a plants leaf in order for photosynthesis to occur?
The chloroplast is the main component/organelle in the process of photosynthesis. Also this organelle is unique to plant cells.
What part of a leaf contains chemicals needed for photosynthesis?
The chloroplasts, specifically found within the cells of the mesophyll tissue, contain the chemicals needed for photosynthesis to occur in a leaf. These chemicals include chlorophyll, which is responsible for capturing light energy, and other molecules essential for the series of reactions involved in photosynthesis.
Which substance is used to remove chlorophyll from a green leaf during photosynthesis experiment?
In a photosynthesis experiment, alcohol, typically ethanol, is used to remove chlorophyll from a green leaf. This process involves boiling the leaf in ethanol, which extracts the pigment and makes the leaf turn white or pale. This allows for the subsequent testing of starch, indicating photosynthesis, as the chlorophyll is no longer present to obscure the results.
what two substances enter and leave the leaf in photosynthesis?
The leaf first takes in Carbon Dioxide, or CO2, into it's self through the bottom of the leaf. It uses the CO2 and makes sugars out of it, water, and sunlight. This reaction makes a byproduct, Oxygen, that the leaf lets out, which we use to breathe.
What would happen if the amount of starch present if the colour of the leaf if other then green?
If the color of a leaf is other than green, it may indicate a lack of chlorophyll, which is essential for photosynthesis. In such cases, the amount of starch present in the leaf could be reduced, as less photosynthesis would lead to lower glucose production and, subsequently, less starch synthesis. Alternatively, if the leaf contains other pigments, it might still be able to perform photosynthesis efficiently, depending on the type of pigment and the light conditions. Thus, the relationship between leaf color and starch content can vary based on the leaf's ability to photosynthesize.
Which gas goes into a leaf for photosynthesis and which gas comes out of the leaf?
A plants leaves are used to catch photons (sunrays) from the sun, carbon dioxide, and water. Those are the three basic ingredients needed for a plant to complete photosynthesis.
