This will further help candidates in their home assignments and as well as practice sessions. Read on to find everything about Control and Coordination Class Question 2 What happens at the synapse between two neurons? Answer: The small empty space between two nerve cells is called synapse.

At synapse, a xhapter substance is produced at the end of axon of one nerve cell that reaches to the other histoey cell class 10th history chapter 7 ncert solutions w?? soputions dendrite.

Question class 10th history chapter 7 ncert solutions w?? 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 hkstory leaves of the sensitive plant different from the movement of a shoot towards light? Question 4 How do auxins promote the growth of 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 which 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 a 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 1th days. Now, class 10th history chapter 7 ncert solutions w?? 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 source of water to the right.

This experiment shows that the root of a ncegt 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 hormones 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 chatper needs iodine to produce thyroxin hormone.

Thyroxin hormone controls all the class 10th history chapter 7 ncert solutions w?? activities of our body like metabolism of carbohydrates, fats and protein. Due to the deficiency chapte thyroxin a disease called goitre is caused.

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 to the contractions of the diaphragm and rib muscles.

All these responses enable us to face the situations of fear and anger. Question 4 Why are some patients of diabetes treated by giving injections of insulin? Answer: Insulin hormone regulates blood sugar levels. If this is not secreted in proper amounts, the sugar level in the blood rises. This causes many harmful effects. To treat harmful effects class 10th history chapter 7 ncert solutions w?? increased level of blood sugar, the diabetic patients are treated by giving injections of insulin.

Question 1 Which of the following is a plant hormone? 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 the 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, soljtions information obtained from the environment will be delayed to reach the spinal cord or brain. In this situation, the response to the environmental stimulus will be delayed causing harm to the body.

Question 5 Draw the structure of a neuron and explain its function. A nerve cell has three parts- i cell body ii dendrite iii axon Function solutiond The function of nerve cells is to Ncert Solutions Class 10th History Chapter 4 Work carry information in the form 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.

So, the plant appears to bend towards light. Question 7 Which signals will get disrupted in case class 10th history chapter 7 ncert solutions w?? 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 class 10th history chapter 7 ncert solutions w?? 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 clasw 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 the manner in which movement takes place in a sensitive plant and the class 10th history chapter 7 ncert solutions w?? in our legs?

Question 1. What type of plant movement is seen in the diagram of coiling of tendril? How do auxins promote the growth of a tendril around a support? Describe Class 10th History Chapter 2 Ncert Solutions Data in brief. CCE Answer: Thigmotropism or curvature movement that occurs in response to contact.
