Why leaf gives out bubbles in hot water and not cold?
Leaves have gaseous exchange through its stomata or free cell surface (in case of water plants). These gases come out in the form of bubbles in water. Hence air bubbles are formed when leaves are in water.
What is Surface water run off?
Surface water is the water that is available on the ground surface. Examples: river water, water in the lake, etc., there are other kinds of waters like atmospheric water in the form of moisture and ground water in the form of acquifers etc.,... Ocean water is NOT a type of surface water--basically, surface water is a drinkable water source.surface water is the water that is avaible on the ground water
What refers to to water that flows over earths surface?
If you are talking about land above sea , then it would be called run off, because when precipitation falls , whether it is rain or snow , at some point it usually makes its way from the land to the sea via flowing over the surface of the earth.
Why can you see your reflection on a shiny surface?
Sometimes, water can act as a mirror. The light that the sun gives off has bounced off of you into the water. When the light reaches the surface of the water, it can do two things. Firstly, it can be refracted underneath the surface. Secondly, it can be reflected back at you and into your eye. Usually, both occurs, although whether enough reflection occurs to make you see your reflection or not depends on several factors. Your eye does something similar. It picks up the light from the sun that has bounced off of objects and creates a picture out of it. While the water acts like a mirror and your eye acts like a lens, the concept is very similar.
What is the continuous movement of water from earths surface to the air and back to earth surface?
The water cycle
What happenes if you dip a leaf into rainwater?
The leaf has a wax coating, so water will roll off or the leaf would float on the water.
Why does water roll off the surface of leaf?
Most leaves are coated in a waxy, waterproof substance that renders them hydrophobic, meaning that they repel water. Some leaves go even further with small bumps called papillae, too small to be seen by the naked eye. The papillae effectively trap bubbles of air, which the water can not displace, and that causes the water to roll off without making contact with the leaf. Think of it kind of like a hovercraft, which uses a pocked of contained air to keep itself above the water, but in reverse.
What makes gabi leaf waterproof?
Gabi leaves are waterproof due to the waxy coating on their surface, which helps repel water and prevent it from being absorbed into the leaf tissues. This waxy layer acts as a barrier, allowing water to bead up and roll off the leaf surface, keeping the leaf dry.
Can a leaf have no waxy surface?
Yes, some leaves may not have a waxy surface. The presence of a waxy residue on a leaf is known as the cuticle; it helps reduce water loss and provides protection. Leaves without a waxy surface are typically found in plants that prefer moist or shaded environments where water loss is less of a concern.
Why water wets glass but not lotus leaf?
Water wets glass because the adhesive forces between water molecules and the glass surface are stronger than the cohesive forces between water molecules. On the other hand, lotus leaves have a rough surface with microscopic bumps that create a high contact angle with water, causing it to bead up and roll off easily due to a combination of low adhesive forces and high surface tension.
What happen if rheo leaves are boiled in water and then a drop of syrup is put on it?
Boiling the rheo leaves in water may soften them, but they may not absorb much of the water due to their waxy surface. Adding a drop of syrup may cause the syrup to rest on the surface of the leaf or roll off due to the hydrophobic nature of the leaf.
Is this water resistant at all?
The ipod touch has a solid surface, so if water is poured over it then the water will just roll off. If the ipod is submerged in water then water will be able to get inside and may ruin the electronics.
How do hydrophobic water-repelling surfaces prevent water from adhering to them?
Hydrophobic surfaces have a low affinity for water molecules, causing water to bead up and roll off the surface instead of sticking to it. This is due to the surface's molecular structure, which repels water molecules and prevents them from adhering.
Why does water roll off a persons skin when the get out of a swimming pool?
water rolls down skin because when the person gets put of the pool the water just fastly perushered off and after it solowly rolls down
What are hydrophobic plants?
Hydrophobic plants have leaves that repel water, causing droplets to bead and roll off. This adaptation helps prevent waterlogging and allows plants to efficiently capture sunlight for photosynthesis. Examples of hydrophobic plants include lotus leaves and water lilies.
Why is a pencil flat sided?
So it doesn't roll off when you place it on a flat surface.
What are the 3 things that can happen to light which strikes a leaf?
When light strikes a leaf, it can be absorbed, transmitted through the leaf, or reflected off the surface. Absorbed light is used in photosynthesis to produce energy for the plant. Transmitted light passes through the leaf to reach other parts of the plant, while reflected light bounces off the leaf's surface and can be used for other purposes.
