How do plants absorb water from the soil?
Roots have hairs on the tips that soak up the water and they then soak the water up the plant and then the water is transported to the other veins in the leaf.
Why does water roll off the surface of a leaf?
because the leaf is non polar or Because the leaf is coated in lipid molecules
Why a tree floats in water?
Leaves contain chloroplasts; which make sugars using sunlight. This is called photosynthesis. One of the by-products of this process is Oxygen. This oxygen sits in the Parenchyma, which is in the middle of the leaf. This gives the leaf a lower density than water; so it floats on the surface. This oxygen, if it is not used by the plant, is later released from the Stoma, which are little holes on the bottom of the leaf; and the leaf sinks.
What is fine network of lines on the undersurface of a leaf?
The fine network of lines on the undersurface of a leaf are called Veins. The water and minerals go to every part of the leaf through these Veins.
What kind of climate and weather conditions do you wil cause a high rate of transpiration?
Warm air can hold more water vapour than cold air therefore transpiration will take place more rapidly into warm air.Furthermore, when the sun shines on the leaves,they will absorb heat as well as light which increases the rate of evaporation of water. In moving air ,the water vapour will be swept away from the leaf as fast as it diffuses out.This will speed up transpiration.The air should also be less humid to accept more water vapour.
Why do you place a leave in hot water then rinse it with cold water?
Placing a leaf in hot water helps to extract flavor and essential oils from the leaf. Rinsing it with cold water helps to stop the cooking process and preserve the color and texture of the leaf.
What is the purpose of the cold water when testing a leaf for starch?
Cold water is used to stop the process of photosynthesis in a leaf. This helps to fix any starch that has been produced in the leaf during the experiment. The cold water also makes the leaf more brittle, making it easier to handle during further steps of the experiment.
When water is used to wash off alcohol from a leaf why does the leaf turns dry?
Because the oxygen in water and peroxide in alcohol mix and tiny bubbles form and when they pop air comes out that makes the leaf dry
Which part of the water hyacinth help it to float?
Leaf petiole
Why dried leaf floats on the surface of apond?
they are lihter than water possible have air bubbles inside and have a widesurface area
which of the following is most likely the result of an organism having lipids in its body?
Water cannot be absorbed through the surface of a leaf
When testing a leaf for starch why is it rinsed in cold water after it is boiled?
Rinsing a leaf in cold water after boiling it is done to stop the enzymatic activity that breaks down starch. Boiling the leaf softens the cell walls, allowing the iodine solution to penetrate and react with any starch present. Rinsing in cold water halts the enzymatic breakdown of starch, preserving the blue-black color reaction with iodine, indicating the presence of starch in the leaf.
What do you call a water lily leaf?
The water lily leaf does not have a special name. It can be referred to as a "water lily leaf' or as the leaf of a certain water lily species.
What are the instructions for examining a moss leaf under a microscope?
To examine a moss leaf under a microscope, first place a small piece of the moss leaf on a microscope slide with a drop of water. Use a cover slip to gently press down on the moss leaf to prevent air bubbles. Adjust the focus on the microscope to observe the leaf's structure, including cells, chloroplasts, and any reproductive structures present.
What gives the colour to the leaf?
Chlorophyll
How is water absorbed by a leaf?
it doesn't the water absorbs the leaf
What is the best method for using leaf gelatine in a recipe?
The best method for using leaf gelatine in a recipe is to soak the gelatine leaves in cold water until they become soft and pliable, then squeeze out any excess water before adding them to the recipe.
