- This slideshow is focused on

The movement of water through a plant

What is needed for the water to move through the plant

What are different parts of a plant doing through this process and how they help this process to be successful.

The entering of water

Firstly, the absorption of water mainly takes place in the based area of the root hair, where the root hair absorbs the water.

Secondly the water is entered into the plant from the roots, which is under ground. Finally

this is how the the water enters the root.

The roots and stems

Basically the root has a lot of jobs a main job of the root is to provide anchorage for the plant. Most importantly the roots are the place where water enters first. The plant root’s cells grow into hair that absorbs the water and other minerals from the soil, although the plant doesn't take any food from the soil. After the roots hair absorbs the water to the inside of the plant The water moves up into the stem. The second step is, after the water is absorbed into the hairs it is travels into the stem of a plant.

Phloem and Xylem

There are two types of tubes in the stem known as Phloem and Xylem.

The Phloem tubes transport food around the plant.

The Xylem tube transports water around the plant.

The Transpiration Stream

The transpiration stream is when the water begins to flow up from the water to the leaf.

Xylem tubes have long unbreakable columns of water that help this process to be successful.

Wax Cuticle

What is a wax cuticle?

Wax cuticle is a waxy layer that is on top of a leaf that is water proof.

What is its job?

it’s job is to lessen the amount of water that leaves the plant. So the plant can have just enough water.

Chloroplast

What is a chloroplast?

Chloroplast is where the photosynthesis belongs in a plant cell. Chloroplast have the the green pigment which makes the whole plant look green.

What is its job?

first of all it gives the plant and leaves the green color and its job is to absorb the sunlight and take advantage of its energy in splitting the hydrogen atom from the oxygen atoms.

Conclusion

In conclusion the plant has a very important job with all it’s variables. The plant produces food and oxygen which helps us humans. They give us air

to breath from. So we should appreciate the plant and not remove it!
