Answer: The small empty space between two nerve cells is called synapse. At synapse, a chemical substance is produced at the end of axon of one ncert solutions for class 10th history chapter 7 inc cell that reaches to the other nerve cell through the dendrite. Thus, information is transmitted from one nerve cell to other nerve cell by synapse. Question 3 Which part of the brain c,ass posture and equilibrium of the body?

Question 4 How do we detect the smell of an agarbatti incense stick? Answer: The smell of agarbatti incense stick diffuses in the air. It is detected by olfactory receptors present in the nose. This information is sent to olfactory lobe by sensory nerves located in the forebrain.
It responds to the so,utions. Question 5 What is the role of the brain in reflex action? Answer: There is no role of brain in reflex action. These involuntary actions are controlled by Ncert Solutions For Class 10th History Chapter 4 Review the spinal cord which take place immediately without thinking of how to respond to the stimuli.
Question 1 What are plant hormones? Answer: Plant hormones are also called phytohormones. Plant hormones are the chemical substances which help in controlling growth, flowering, height, development of plants and their response to the environment.
Different types of phytohormones are � auxins, gibberllins, cytokinins, abscisic acid and ethylene. Question 2 How is the movement of leaves of the sensitive claws different from the movement of Ncert Solutions For Class 10th History Chapter 4 Table a shoot towards light? Question 4 How do auxins promote the growth hisgory a tendril around a support? Answer: When the tip of a tendril touches a support, then the auxins present in its tip move to that side of tip which is away from the support.
Auxins promote growth. So, due to more auxins in it, the side of tendril away from the support grows faster and becomes longer than the side eolutions is in contact with the support and makes the tendril twirl or bend around the support. Question 5 Design an experiment to demonstrate hydrotropism. Answer: Take two glass troughs A and B and fill each one of them two-thirds with soil. In trough A plant ofr tiny seedling. Water the soil in trough A daily and uniformly.
Do not water the soil in trough B but put some water in the clay pot. Leave both the troughs for a few days. Now, dig up the seedlings carefully from both the troughs without damaging their roots. We will find that the root of seedling in trough A is straight. On the other hand, the root of seedling in trough B is found to be bent to the right side i. In trough A, the root of the seedling gets water from both sides.
But in trough B, the roots get water oozing out from the clay pot which is kept on the right. Therefore, the root of seedling in trough B grows and bends towards the ncert solutions for class 10th history chapter 7 inc of water to the right. This experiment shows that the root of a plant grows towards water. In other words, the root of a plant is hydrotropism. Question 1 How does chemical coordination take place in animals? Answer: Chemical coordination in animals takes place through the hormones secreted by the endocrine glands.
Coordination in animals takes place through hormone system as well as nervous system which is called endocrine. Endocrine glands secrete animal solutionx directly into the blood that reach to the specific cells. Special type of molecules are present on the surface of cells to detect these hormones.
These cells act according to the information that a particular hormone carries. Question 2 Why is the use of iodised salt advisable? Answer: It is advised to use iodised salt because thyroid gland needs iodine to produce thyroxin hormone.
Thyroxin hormone controls all the metabolic activities of our body like metabolism of carbohydrates, fats and protein. Due to the deficiency of thyroxin a disease called goitre is ncert solutions for class 10th history chapter 7 inc. Question 3 How does our body respond when adrenaline is secreted into the blood?
Answer: The heart beat increases when adrenaline is secreted into the blood so that more oxygen is supplied to our muscles. The blood supply to the digestive system and skin decreases because the small arteries around the muscles of these organs contract.
This turns the direction of blood towards our skeletal muscles. The breathing rate also increases due ncert solutions for class 10th history chapter 7 inc the contractions of the diaphragm and rib muscles. All these responses enable us to face the situations chaptr fear and anger.

Question 2 The gap between two neurons is called a a dendrite b synapse c axon d impulse Answer: b Synapse. Question 3 The brain is responsible for a thinking b regulating the heart beat c balancing ncert solutions for class 10th history chapter 7 inc body d all of the above Answer: b All of the.
Question 4 What is the function of receptors in our body? Think of situations where receptors do not work properly. What problems are likely to arise?
The function of receptors is to detect information from the environment. For example, olfactory receptors detect smell. If receptors do not work properly, the information obtained from the environment will be jistory to reach the spinal cord or brain.

A nerve cell has three parts- solutins cell body ii dendrite iii axon Function : The function of nerve cells is to carry information in the ncert solutions for class 10th history chapter 7 inc of electrical signals which are called nerve impulses.
Cells receive stimulus to send it to spinal cord and brain and carry the message from brain to the target organ. Question 6 How does phototropism occur in plants? Answer: The movement in any part of a plant due to light is called phototropism. The shoot of plant shows positive phototropism and roots show negative phototropism. Phototropism in plants occurs due to the hormone auxin.
When light falls on one side of a plant, the secretion of auxin hormone is more in the part away from the light. Hence, auxin causes growth in length of the cells in shady ncert solutions for class 10th history chapter 7 inc. So, the plant appears to bend towards light.
Question 7 Which signals will get disrupted in case of a spinal cord injury? Answer: i All the involuntary actions will get disturbed. Therefore, the quick responses required to safe guard the body will not take place.
Question 8 How does chemical coordination occur in plants? Answer: Chemical coordination in plants takes place with the help of plant hormones. In most of the regions where division takes place meristematic regions stimuli cells secrete chemical compounds hormone. These substances identify the information by stimulating the other nearby cells and communicating the information.
Question 9 What is the need for a system of control and coordination in an organism? Answer: An organism needs control and coordination system for the following functions : i To save the body of the organisms from the harmful changes in the environment. Question 10 How are involuntary actions and reflex actions different from each other?
Question 11 Compare and contrast nervous and hormonal mechanisms for control and coordination in animals. Question 12 What is the difference between 10thh manner in which movement takes place in a sensitive plant and the movement in our legs? Question 1. What type of plant movement is seen in the diagram of coiling of tendril?
