CBSE Class–VII Science NCERT Solutions CHAPTER-1 NUTRITION IN PLANTS Question 1. Why do organisms need to take food? Answer: Organism needs food to (i) Get energy to do work. (ii) Build body (iii) Repair damage in the body (iv) Maintain the functions of the body Question 2. Distinguish between a parasite and saprophyte. Answer: Parasite Saprotroph The organism that grows on the body of another organism and derives nutrients from it is known as a parasite  The organism that obtains nutrients from the dead or decaying organic matter is called saprotroph. They directly feed on living organisms for their nutrition.They feed on dead and decaying organism.They take the readymade food from the host.They take the digested and decayed food.Examples:­ Cuscuta and orchidsExamples:­ Fungi and some bacteria. Question 3. How would you test the presence of starch in leaves? Answer: Steps to test the presence of starch in leaves : Step 1: A fresh leaf is taken. Step 2: The leaf is boiled in water for few minutes to kill the cells in the leaf. Step 3: Now, dip this leaf in iodine solution. Step 4: The color of the leaf will changes into blue black color when iodine is added to it which shows the presence of starch in it.  Question 4. Give the brief description of the process of synthesis of food in green plants. Answer: Photosynthesis is the process synthesis of food in the plants with the help of chlorophyll and carbon dioxide in the presence of sunlight. Water and minerals present in the soil are absorbed by the roots and transported to the leaves by the vessels. Carbon dioxide from air is taken through stomata present in leaves. Leaves are the food factories of the plants which capture the energy of the sunlight with the help of chlorophyll. This energy is used to synthesize food from carbon dioxide and water.   Question 5. Show with the help of a sketch that the plants are ultimate source of food. Answer:  Question 6. Fill in the blanks: (a) Green plants are called ----------- since they synthesise their own food. (b) The food synthesised by the plants is stored as ----------------. (c) In photosynthesis solar energy is captured by the pigment called ------------. (d) During photosynthesis plants take in ------------- and release --------------. Answer: Fill in the blanks: (a) Green plants are called autotrophs since they synthesise their own food. (b) The food synthesised by the plants is stored as starch. (c) In photosynthesis solar energy is captured by the pigment called chlorophyll. (d) During photosynthesis plants take in carbon dioxide and release oxygen. Question 7. Name the following: (a) A parasitic plant with yellow, slender and tubular stem. (b) A plant that has both autotrophic and heterotrophic mode of nutrition. (c) The pores through which leaves exchange gases. Answer: (i) Cuscuta (ii) Insectivorous plants (iii) Stomata Question 8. Tick the correct answer: (a) Amarbel is an example of : (i) Autotroph (ii) Parasite (iii) Saprophyte (iv) Host (b) The plant which traps and feeds on insects is: (i) Cuscuta (ii) China rose (iii) Pitcher plant (iv) Rose Answer:(a) (ii) parasite   (b) (iii) Pitcher plant Question 9. Match the item in given column I with those in column II.

On meeting a mynah, Golu asks what does a crocodile eats for dinner. Most noteworthy, Golu had no experience of a crocodile. He had never before seen a crocodile and had no idea about its diet. Consequently, Golu began to grow more and more curious regarding the crocodile and its eating habit. In order to search for the answer, Golu decided to visit the great Limpopo river due to the advice given by the mynah.

Bishop Always Ready to Help Others
The Bishop is always ready to help the needy pa-sons of his parish. He goes to attend to Marie’s mother who is feeling poorly. He is out in cold without supper. He sells his salt cellars to help Mere Gringoire to pay her rents. His sister Persome feels that her brother is the dupe of every idle vagabond and old lying woman. He has sold his land, his furniture and spent all his savings to help others. Persome feels that her brother’s generosity and innocence is being misused by the people of his parish. But the Bishop thinks that this world is full of suffering and he can do very little to help the sufferers.

Convict Enters Stealthily with a Knife
The convict enters with a long knife and seizes the Bishop from behind. He warns the Bishop not to play any trick with him. He is too old a bird to be caught with chaff. Persome is frightened when she sees a knife in his hand. The convict is staring at them like a wild beast. The Bishop asks Persome to give company to the guest at supper. The convict eats greedily and throws a bone on the floor. Persome leaves the Bishop with the convict and goes to her room. Then the convict narrates his story.

Convict Narrates His Tragic Story
Once the convict had a little hut and a wife. Then came the bad year. He was out of job and had no money. His wife Jeanette fell ill. She was dying. He stole to buy her food. He was arrested. He pleaded to them why he stole but they laughed at him. He was sentenced to ten years in the prison hulks. The night he was sentenced, he was told that Jeanette was dead.

Life in ‘Hell’
He was no more a man now. He became a wild beast. The jail employees chained him like a wild beast. They lashed him like a hound. He was fed on filth and covered with vermin. They took away his soul and gave a devil in its place. But one day they were careless and he escaped.

Convict Steals Bishop’s Silver Candlesticks
The convict comes to know that he is with a Bishop. He warns him not to try to convert him. He doesn’t want any damn religion and the church. The Bishop asks him to go to bed. When left alone, the convict sees the silver candlesticks. He knows that they were given to the Bishop by his mother. His heart goes soft. But he soon hardens himself, steals the candlesticks and goes out into the darkness.

Convict is Caught and Brought Back to Bishop
When Persome and the Bishop get up next morning, they find the candlesticks and the convict missing. Soon they hear a knocking. A sergeant enters with three soldiers and the convict in chains. The sergeant tells that they found him (convict) walking on the road with the candlesticks. They arrested him on suspicion. They identified the candlesticks of the Bishop and so they brought them there to him. The Bishop saves the convict by declaring that those candlesticks were given to him as a gift. The convict is freed again.

Convict is Transformed
The Bishop saves the convict from going to “hell” again. This leaves a deep impression on the convict. He is a transformed man now. He is no more a wild beast. He sobs and repents. The Bishop gives him the candlesticks and the convict takes them in absolute amazement. The Bishop shows him a very lonely path through the woods at the back of his cottage leading to Paris. The soldiers don’t like lonely paths at night. The Bishop blesses the convict and tells him that “this poor body is the Temple of the Living God”.

While using manuacripts,historians face many difficulties.Manuscripts were written by hand and there were small but significant differences between any two copies.The scribes who copies them introduced changes.As a result historians have to read same manuscript version of the same text to give what the author had originally written.

Moni Shree 5 years ago

Thank you

Gaurav Seth 5 years ago

The historians face several difficulties in using manuscripts. There was no printing press in those days so scribes copied manuscripts by hand. Manuscript copying is not an easy job. As scribes copied manuscripts, they also introduced small changes—a word here, a sentence there. These small differences grew over centuries of copying until manuscripts of the same text became substantially different from one another. This is a serious problem because we rarely find the original manuscript of the author today. We are totally dependent upon the copies made by later scribes. As a result historians have to read different manuscript versions of the same text to guess what the author had originally written.

Cells cannot survive on their own. They need power to stay alive. They need energy to perform functions such as growth, maintaining balance, repair, reproduction, movement and defense. This means all living organisms must obtain and use energy to live.

While the sun is an excellent source of energy, not all forms of life can utilize the sun's energy directly. This lesson describes how plants transform the sun's energy into potential energy stored in sugar, how living organisms utilize energy in sugar to perform work, and how the relationship between photosynthesis and cellular respiration is necessary for life.
