NCERT Solutions for Class 7 Science Chapter 11 - Transportation in Animals and Plants: In most animals, the blood that circulates in the body distributes food and oxygen to different cells of the body. It also carries waste products from different parts of the body for excretion. The circulatory system consists of the heart and blood vessels. In humans, blood flows through arteries and veins and the heart acts as a pumping organ and blood consists of plasma, RBC, WBC, and platelets. You know why our blood is red, due to the presence of a red pigment that is hemoglobin. The human heart beats about 70–80 times per minute in an adult person, which is called the heart rate, where arteries carry blood from the heart to all parts of the body and veins carry blood from all parts of the body back to the heart. You will also study the removal of waste products from the body, which is called excretion.
Here are the important topics of NCERT Solutions for Class 7 Science Chapter 11 - Transportation in Animals and Plants mentioned below:
11.1 Circulatory System
Blood
Blood Vessels
Heart
Heartbeat
11.2 Excretion in Animals
Excretory System in Humans
11.3 Transport of Substances in Plants
Transport of Water and Minerals
Transpiration
You know that fish excrete waste substances such as ammonia which directly dissolve in water and birds, insects and lizard excrete uric acid in semi-solid form. Now if we talk about plants then nutrients are transported along with water to the entire plant via the vascular tissue called xylem. The vascular tissue for the transport of food to the various parts of the plant is phloem. A lot of water is lost by plants in the form of vapor through stomata during transpiration. Transpiration generates a force which pulls up water absorbed by the roots from the soil, to reach the stem and leaves.
After going through this chapter, you must be able to get the NCERT Solution of these questions which are mentioned below, as these questions are from the Science book of NCERT.
Q1. Why is the transport of materials necessary in a plant or in an animal? Explain.
Q2. What will happen if there are no platelets in the blood?
Q3. What are stomata? Give two functions of stomata.
Q4. Does transpiration serve any useful function in the plants? Explain.
If you have any problem in answering these questions or you are not getting the correct answers then don't worry, NCERT Solutions for Class 7 Science Chapter 11 - Transportation in Animals and Plants is there for you to help. Solutions for NCERT Class 7 Science Chapter 11 - Transportation in Animals and Plants will give you answers to all the questions which are mentioned in the NCERT book.
