Journey of the Plant

1. Journey of the Plant Lara Matic

2. Plants Growth This presentation shows how the water travels from the roots to the highest leaves on a plant. The basic thing of a plant is that it needs water, oxygen and nutrients to grow. This is everything that is needed for the whole plants growth.

3. Roots The roots are the main and big part of the plant, they have to: • Grip the plant to the soil • Absorb water and mineral nutrients from the soil • Store food • And sometimes produce a new plant The roots have different parts, they have the; Primary Roots: it is the thickest and it goes downwards Secondary Roots: come from the primary and they go side wards Roots cap: it protects the root and it is made to guide the root by perceiving gravity Roots Hairs: they absorb water and nutrients from the soil.

4. Roots Within roots there are areas that store food with tubes called, xylem and phloem. These tubes take water and minerals up to the leaves. When they come back down they bring food for nourishment and storage. There are small root hairs that make the amount of water and minerals smaller to absorb.

5. Steam The steam is a important part of the plants growing functions. The steam holds up the leaves and flowers. When it does this the flowers get pollination and the leafs get photosynthesis. The functions the plant has are: • To maintain the flowers and leaves from a certain distance • Have the nutrients and waters inside of them The steam is a bit like the root, it has different parts to it as well. They are: Main stem – it is the most important steam in the plant. The secondary steam grows from it. Secondary Steams – it grows from the main steam and it develops Nodes – leaves grow at their level Internodes – these are the spaces between the nodes The tubes in the steam take the water and minerals up into the plant are called xylem and the tubes that carry the food back down are called phloem.

7. Leaves There are many different types of leafs, but all leaves are made up of two parts, the blade and the petiole. The blade is the expanded part of the leaf. Inside the blade there are different types of parts called different names. There is the vein, they are the lines that go around the whole leaf. The upper and lower layer have guard cells. The guar cells manage the stomata, small opening in the leaf that take in carbon dioxide and emission during photosynthesis. The petiole is the connection between the steam and the blade (the blade being the most expanded part of the leaf). There are some leafs without petiole which are called stalk less or sessile. The wax cuticle is found at the top and bottom of the leaf. The thicker the wax cuticle the less water will diffuse into the air. This is why the cactuses leaves are thick, because there isn’t enough water in the desert so the cactus can’t let any water get out.

8. Leaves Leaves are the process of food making which is photosynthesis. For this to happen, carbon dioxide and water, in the presence of chlorophyll are all changed into glucose. This is the food for all plants. Photosynthesis gives food for plants and oxygen for living things that need to breathe.

9. How Water Moves Through the Plant Eventually leaves release water through there pores after the water has moved up through the steam and leaves. This evaporation into the air is transpiration and a plant does this through its lives.
