Electrons are the negatively charged particles of atom. Together, all of the electrons of an atom create a negative charge that balances the positive charge of the protons in the atomic nucleus. Electrons are extremely small compared to all of the other parts of the atom.

Jute is obtained from the stem of jute plant. In India, jute is grown in West Bengal, Bihar and Assam. When the jute plant is at its flowering stage, it is harvested. Then, the stem of such harvest plant are immersed in water for a few days so that they rot. The fibres are then separated from the stem by hand.

Leaves prepare food in the presence of a green coloured substance called chlorophyl. They also use Carbin Dioxide for this process. Oxygen is given out in this process and the food prepared by the leaves ultimately gets stored in different parts of the plant. This process is known as Photosynthesis

Siya Panchal 4 years ago

The process by which the green leaves prepare their food is called photosynthesis.

Radhika Mantri 4 years ago

On the upper part of leaf there present number of small opening or pores called stomata. Stomata help in exchange of gases, which is intake of carbon dioxide and release of oxygen in the presence of water and sunlight by the process of photosynthesis. Plants prepare their food by photosynthesis.

Weaving and Knitting

Meghna Thapar 4 years ago

Processing fibres into wool:

The wool which is used for knitting sweaters and weaving shawls involves following steps:

  1. Shearing: The process of removing hair from the body of a sheep in the form of fleece is called shearing. Usually the hairs are removed during the hot weather which enables sheep to survive without their protective coat of hair. The hair provides woolen fibres and than are processed to obtain woolen yarn. Shearing does not hurt the sheep as the upper most layer of skin is dead.

 

  1. Scouring: The process of washing the fleece that removes dust, dirt, dried sweat and grease is called scouring. This process makes the fleece of sheep clean. The scoured fleece is then dried.

   

  1. Sorting:  The process of separating the fleece of a sheep into sections according to the quality of woolen fibres is called sorting.  The hairy skin is sent to a factory where hair of different textures is sorted. The same quality wool obtained from the fleece of large number of sheep is than mixed together.
  2. Dyeing: The hair of sheep is white, brown, or black in color. The white woolen fibres obtained by sorting can be dyed in different colors.

 

  1. Combing: This is a process of preparing woolen fibres for spinning the yarn. It is done by using combs having metal teeth.
  2. Spinning: The long woolen fibres are spun into thick yarn called wool.

The part of skeleton which can be bent and is not as hard as bone is known as cartilage.

Siya Panchal 4 years ago

Some additional parts other than bones which can be bent are called cartilage ex: ear bones, parts of nose etc
Cartilage is a smooth bone in our body. It is not hard bone. It is much softer than a bone. It is present in our upper ear pinna.

Yogita Ingle 4 years ago

It is a thin, fibrous, flexible connective tissue, which is mainly found in the external ear, larynx, respiratory tract and the articulating surface of the joints. These cartilages lack blood vessels; therefore, the growth and development of these tissues are slower compared to that of other tissues. Altogether, there are three different types of cartilages, namely:

  1. Hyaline cartilage: It serves as a shock absorber and allows the smooth movement of the bones at joints. They are mainly found in the nose, respiratory tract and joints
  2. Fibrocartilage is found in the knee and it is tough and inflexible.
  3. Elastic cartilage is found in-ear, epiglottis and larynx. It is the most flexible cartilage.

  • Shape of the shadow is always similar to that of the object but the size varies.
  • Shadows of different types of objects may have similar shape as the amount of light they may be blocking is same.
