Well, it's not really a tube. It's more like a stack of cells in a column, and the water moves along by being transferred from cell to cell. If you want to learn more about this transfer, called capillary action, try this website: dwb.unl.edu/Teacher/NSF/C01/C01Links/ga.water.usgs.gov/edu/capillaryaction.html - 7k
Varies from plant to plant depending on what compounds are in their leaves. Most likely Oxygen, Carbon, Nitrogen, and Hydrogen.
because they produce new material for growth
The phloem carries the food down from the leaves. Not to be confused with xylem, which carries water up to the leaves.
Carbon dioxide is absorbed as a gas by the leaves of the plant.
Leaves are mainly responsible for photosynthesis in a plant.
the plant has to get chloraphill in the leaves can help a plant
gram plant has compound leaves.
yes they are a plant first leaves
it makes the plant leaves green
Plants use a process called photosynthesis in order to change sunlight into food. This process takes place mostly in the leaves of a plant. Leaves are large and flattened so that a large area of chlorophyll is exposed to the sunlight. Leaves are also used in a process called transpiration, which helps draw water and dissolved minerals up the plant's stem from the roots, where these substances have been absorbed from the soil. During transpiration, water evaporates through tiny holes in the leaves. More water is drawn up through a thin tube extending down the plant's stem.
Water enters the root cells by osmosis and enters into the xylem. The pressure of water entering the xylem creates osmotic pressure, pushing the column of water up through the stem. Water evaporating on the surface of the leaf cells pulls on other molecules and pulls the column of water up the plant and into the leaves.
because the leaves create food for the plant.
Magnesium deficiency create dead leaves and yellow leaves on a plant.
The leaves make the food for the plant.
A cactus has no leaves.
