FAQs on Transport of Substances in Animals and Plants Class 7 Worksheet Science Chapter 7

1. What are the main functions of the circulatory system in animals?
Ans. The main functions of the circulatory system in animals include transporting oxygen and carbon dioxide, delivering nutrients and hormones to cells, removing waste products, and helping to maintain body temperature and pH balance.
2. How do plants transport water and nutrients?
Ans. Plants transport water and nutrients through specialized tissues called xylem and phloem. Xylem carries water and dissolved minerals from the roots to the rest of the plant, while phloem transports sugars and other organic compounds produced during photosynthesis from the leaves to other parts of the plant.
3. What is the role of the heart in the transport of substances?
Ans. The heart plays a crucial role in the transport of substances by pumping blood throughout the body. It ensures that oxygen-rich blood reaches the tissues and organs while simultaneously helping to return deoxygenated blood back to the lungs for oxygenation.
4. Why is diffusion important for the transport of substances in cells?
Ans. Diffusion is important for the transport of substances in cells because it allows nutrients, gases, and waste products to move across cell membranes from areas of higher concentration to areas of lower concentration. This passive process is essential for maintaining cellular function and homeostasis.
5. What are some common diseases related to the transport of substances in animals?
Ans. Common diseases related to the transport of substances in animals include anemia (a deficiency of red blood cells or hemoglobin), atherosclerosis (buildup of plaque in arteries), and heart failure (the heart's inability to pump efficiently). These conditions can significantly affect the circulatory system's ability to transport essential substances effectively.
