Every root grows a mass of tiny hairs near its tip to absorb water from the soil.
Root hairs are cells. They take water to the main root. Then the main root brings the water to the main plant. The roots also help hold the plant in the ground.
The inside of a root has four different parts. The epidermis is the outside part. It is like our skin. It protects the inside parts of the root. Plants take in water from the soil through their roots. The water passes through the vascular rays until it reaches the center of the root, the stele. This is where the veins are located. The veins are called xylem. They carry the water and food through the plant. Between the epidermis and the stele is the fleshy cortex
GERMINATION;
Germination happens when a baby plant is growing. The plant is between the cotyledons. This is a seed. The seed is underground and is collecting nutrients.
When a seed starts to grow, we say it germinates. The cotyledons store food for the baby plant inside the seed. When the seed starts to germinate, the first thing to come out is the main root. The skin starts to split and the tiny shoot straightens, carrying the cotyledons with it. The main root gets bigger. Side roots appear and so do leaves. To grow, the seed's growing conditions usually have to be damp, warm, and dark, like springtime soil. A dry seed will stay dormant unless it soaks in some water. Then it will start to germinate.
First the young root appears, The skin splits and the shoot straightens, pulling the cotyledons with it, then the main root gets bigger and grows side roots, and the first leaves appear. WOOHOO!
Photosynthesis
Do plants sleep? Yes. At night time, plants can not make food, so they shut down by closing their stomata. Animals inhale oxygen and exhale carbon dioxide. Green plants are the only plants that produce oxygen and make food, which is called photosynthesis. Photosynthesis means ''putting together with light.'' This takes place in chloroplasts, which have chlorophyll in them. Chlorophyll absorbs the sunlight. From sunlight, green plants combine carbon dioxide and water to make sugar and oxygen. Green plants use sugar to make starch, fats, and proteins. There are tiny pores called stomota. Carbon dioxide and oxygen enter and leave through the stomata respectively.
