the roots make the water flow up from the ground through the xylem.
The xylem tissue in the leaf supplies water to the cells for photosynthesis. Xylem is responsible for transporting water and nutrients from the roots to the rest of the plant, including the leaf cells. This water is needed for photosynthesis to occur, as it is a key component in the process.
The sun supplies energy in the form of sunlight to the leaf through photosynthesis. This energy enables the leaf to convert carbon dioxide and water into glucose, a form of sugar that provides food and nutrients for the plant.
Water is transported to leaf cells primarily through the xylem, a type of vascular tissue in plants. This process relies on capillary action, root pressure, and transpiration pull, where water evaporates from the leaf surface, creating a negative pressure that draws water upward from the roots. Additionally, osmosis allows water to move into leaf cells from surrounding tissues, ensuring they remain turgid and functional for photosynthesis.
Placing a leaf in distilled water would allow water to enter the leaf through osmosis, leading to an increase in turgor pressure within the cells. This influx of water could cause the leaf to become turgid and firm.
When an elodea leaf is mounted on a 10 percent salt solution, the cells of the leaf will lose water through osmosis. This will cause the cells to shrink and the leaf to become flaccid. The high salt concentration outside the cells will create a hypertonic environment, leading to water moving out of the cells to try to balance the concentration of solutes.
The venation of an apricot leaf is generally reticulate or pinnate, with veins branching out from a central midrib. Apricot leaves typically have a network of veins that supply nutrients and water to the leaf cells.

A leaf obtains water through the process of transpiration, where water is absorbed by the roots from the soil and transported to the leaves through the xylem vessels. Once in the leaves, water is used in various metabolic processes and is also lost through small openings called stomata during transpiration.
The xylem tissue in the leaf supplies water to the cells for photosynthesis. Xylem is responsible for transporting water and nutrients from the roots to the rest of the plant, including the leaf cells. This water is needed for photosynthesis to occur, as it is a key component in the process.
The hypothesis of an osmosis lab with an Elodea leaf could be that the Elodea leaf will lose water and shrink when placed in a hypertonic solution due to water moving out of the leaf cells by osmosis, causing the cells to become flaccid. Conversely, if the Elodea leaf is placed in a hypotonic solution, it may gain water, swell, and become turgid as water moves into the leaf cells via osmosis.

The Food Making Cell In A Leaf, Is Obviously A Cell Inside A Leaf That Get Their Supply Of Carbon Dioxide Through Tiny Pores (stomata) Which Are Mainly On The Underside Of A Leaf.(:I think that it is the mesophyll cells which contains palisade cells and inter-cellular space
Leaf cells perform photosynthesis, converting sunlight, water, and carbon dioxide into glucose and oxygen. They also regulate water and gas exchange through stomata, help support the structure of the leaf, and store nutrients for the plant.
When you deal with problems like this, you need to consider diffusion and osmosis. In this case, you would refer to diffusion, which is the movement of water across a membrane from high concentrations to low concentrations (to try to balance the concentrations). First consider what happens to the cells when you place the elodea leaf in the salt solution; the water in the cells tries to balance the high concentration of salt (sodium chloride) in the surrounding solution, so the water leaves the leaf, thus the cells shrink. Now when you put the elodea leaf into regular water again, there is a higher concentration of water in the surrounding environment compared to inside the leaf's cells, so in attempt to balance concentrations, water goes INTO the cells, thus the cells in the elodea leaf swell (expand).
