Important points to Remember about Transportation in plants and Animals Class 10 :
- Transportation is a vital process in plants and Animals. Trees transport all the water and nutrients from roots to the other parts of plants for survival from its roots to the tips of the leaves.
- For the verious metabolic process of plants like photosynthesis, transpiration, guttation raw materials should be transported from root to the leaves.
- For transport in plants, they need a transport system to move food, water, and minerals around because for them no heart, no blood, and since these plants do not have a circulatory system, transportation makes up for it. Plants have tissues to transport water, nutrients and minerals.
- Plants have two transport systems – xylem and phloem.
- Generally Xylem tissue transports water and mineral salts from the roots to the other parts of the plant,
- while phloem tissues transports Carbohydrates, sucrose and amino acids from roots to the leaves and other parts of the plant.
- Transport of verious nutrient materials is necessary in both plants and animals as every cell needs a regular supply of nutrients and oxygen for production of energy through verious metabolic reactions.
- Transportation in animals is defined as movement of Nutrients, water and oxygen to different parts of the body by use a system like circulatory system and excretory system.
- Blood flows in the blood vessels and transports the Nutrients or digested food from the small intestine to every parts of the body. There are mainly two types of blood vessels veins and arteries.
