Class 10 Science - ANDHRA-PRADESH
Transportation
The Chapter 'Transportation' in Class 10 Science explores how essential substances like oxygen, food, water, and waste materials are moved within plants and animals. For AP Board (BSEAP) examinations, this chapter is crucial as it carries significant weightage in Biology. Students will learn about the human circulatory system, structure of the heart, blood vessels, lymphatic system, and transport mechanisms in plants like xylem and phloem. Understanding these life processes helps explain how multicellular organisms maintain internal stability and is a frequent source of both multiple-choice and diagram-based long-answer questions in the board exams.

Xylem
Plant tissue responsible for the transport of water and dissolved minerals absorbed from roots to the rest of the plant body.
Phloem
Plant tissue responsible for the translocation of synthesized food products (sugars) from the leaves to other parts of the plant.
Double Circulation
A pathway in human beings where blood passes through the heart twice during each complete circuit of the body, separating oxygenated and deoxygenated blood.
Blood Pressure
The force exerted by blood against the wall of a blood vessel, typically measured as systolic and diastolic pressure using a sphygmomanometer.
Lymph
A colourless fluid containing white blood cells that drains through the lymphatic system, helping in immunity and returning tissue fluid to the blood circulatory system.

Board Exam Info
In the Andhra Pradesh (BSEAP) Class 10 Science (Biology) paper, the 'Transportation' chapter typically carries around 4 to 6 marks. Students can expect 1-mark objective questions, 2-mark short answers (such as differences between arteries and veins, or xylem and phloem), and 4-mark questions often involving the labeling of the internal structure of the human heart or explaining the mechanism of transportation in plants.
Frequently Asked Questions
What is the difference between arteries and veins?
Arteries carry oxygenated blood away from the heart to the organs (except the pulmonary artery), and have thick, elastic walls. Veins carry deoxygenated blood from the organs back to the heart, have thinner walls, and possess valves to prevent backflow.
Why is double circulation necessary in humans?
Double circulation prevents the mixing of oxygenated and deoxygenated blood, which allows a highly efficient supply of oxygen to the body. This is essential for warm-blooded animals like humans to maintain their body temperature and high energy needs.
How does water move upward in tall plants?
Water moves upward mainly due to the transpiration pull. The evaporation of water from leaf surfaces (transpiration) creates a suction force that pulls water up from the roots through the xylem vessels.
