How is osmosis involved in supplying water for photosynthesis in the leaf?
Because osmosis is related to the movement of water molecules.
How does water and CO2 for photosynthesis enter a leaf?
Water enters a leaf through the roots and travels through the stem to reach the leaves. Carbon dioxide enters a leaf through tiny pores called stomata on the underside of the leaf. Once inside the leaf, both water and carbon dioxide are used in the process of photosynthesis to produce glucose and oxygen.
What allows water vapor into and out of a leaf?
Water vapor enters and exits a leaf through small openings called stomata, which are located on the surface of the leaf. When the stomata are open, water vapor can diffuse in and out of the leaf, allowing for gas exchange and regulating the leaf's internal water content.
Describe the path taken by water at the moment it enters the leaf and leaves through the stomata?
Water enters the leaf through the roots and moves up through the stem to the leaves via the xylem vessels. Once in the leaf, water moves through the mesophyll cells and eventually evaporates from the stomata as water vapor during transpiration.
Contrast the manner in which water reaches the inside of a leaf with the manner in which carbon dioxide reaches the inside of a leaf?
It depends on the plant. If you're talking about, say, a tree, the water is carried up from the soil. That's why you water a houseplant. Carbon dioxide enters through holes in the bottom of the leaf called stomata.
What molecule enters a leaf from the atmosphere?
Carbon dioxide (CO2) is the molecule that enters a leaf from the atmosphere during photosynthesis.
The cellular transport process by which carbon dioxide enters a leaf and by which water vapor and oxygen exit?
osmosis
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.
Describe the pathway followed by a water molecule from the time it enters a plant root to the time it enters a plant root to the time it escapes into the atmosphere from a leaf?
A water molecule enters a plant root through specialized cells called root hairs and moves up through the xylem tissue, driven by capillary action and transpiration pull. It then flows through the stem and into the leaf where it exits the plant through tiny pores called stomata as water vapor, a process known as transpiration.
How water travels through a leaf?
Water enters a leaf primarily through the roots via the xylem vessels, then moves up the stem to the leaf through a process called transpiration. Once in the leaf, water evaporates from the stomata on the leaf surface, creating a negative pressure that pulls up more water from the roots through the xylem. This continuous flow of water through the leaf helps transport nutrients and maintain cell turgidity.
Why carbon dioxide enters the leaf?
it has no choice but to
What happens when a leaf is put in water?
When a leaf is placed in water, the process of osmosis occurs. Water enters the leaf cells through the stomata and cell walls, causing the leaf to swell and potentially change color. Over time, the leaf may become waterlogged and eventually decompose.
