Prepare a magazine specifying the importance, relevance, and scope of stem cells. |
|
Answer» Stem cell Stem cell are specified cells that can transform to any kind of cell. They are also known as root cells. They transform to other cells by a long process of differentiation. Stem cells can either transform to other cells or exist as such. When the cell in the tissues get destructed, new cells originate from stem cells. Stem cells are seen in bone marrow, skin, digestive tract etc. Today it is possible to develop desired cells from stem cells under specific conditions of laboratories. It is expected to make tremendous change in the treatment of blood cancer, diabetes, parkinson’s diseases etc. and in the development of artificial organs through the research works of in stem cells. |

Stem cells for Cancer treatmentTvm:- Scientists say that the production of tissues from stem cells may cause drastic change in the treatment of Cancer…Did you read the news report? What are stem cells? How do they become useful in the treatment of Cancer? |
|
Answer» Stem cells are specialized cells that can be transformed to any kind of cell. Stemcells modify to other cells through prolonged differentiation. When cells destroyed, new cells originates from stem cells. In research laboratories desired cells are formed from stem cells. New cells, instead of cancer cells, can be produced from stem cells. |

How is the destruction of cells in tissues compensated? |
|
Answer» When the cells in the tissues get destroyed, new cells originate from cells. Stem cells are found in bone marrow, skin, digestive fact etc. |

Animal tissues are mainly classified into 4 (a) Epithelial tissue (b) Nervous tissue (c) Muscular tissue (d) Connective tissue |
|
Answer» 1. Epithelial Tissue:- Covers and protects the body. Covers the inner lining of the alimentary canal Performs the functions like protection, absorption, production of secretions, etc. 2. Nervous Tissue:- Controls and Coordinates physiological Activities Helps to respond to particular stimuli 3. Muscular Tissue:- Makes the movement of the body possible. 4. Connective Tissue:-
Meristematic tissues Meristematic cells are specialized cells seen at the tip of the stem and root in plants. They divide rapidly and helps in the growth of plants.

Our body is developed from a single celled zygote. How do this much organs and organ system sare formed in our body? |
|
Answer» Zygote divides continuously and forms the foetus that consists of cells differ in shape, size, and content. Foetal cells gradually attain diversity in structure and function. Thus different organs and organ systems are formed. |
|
| 20. |
Complete the following table by finding out the systems to which the organs listed in the table belong to:OrgansOrgan systemHeart, blood vesselsNose, trachea, lungsKidney, ureter, urinary bladderBrain, nerves |

Answer»
An organism is composed of various organ systems. Therefore the structure of organisms is highly complicated. Cells are the basic unit of life. Cell parts are composed of different substances. In higher organisms diverse tissues act complementary to each other and perform various life processes. |

|
| 30. |
How do the water and salts absorbed by the roots reach the leaves? |
|
Answer» In plants, the water and salts absorbed by the roots are transported to the leaves through specialised tissues called vascular tissues. |
|
| 31. |
Why plant growth is confined to specific parts? |
|
Answer» In plants, specific cells called meristematic cells are concentrated the tips of roots and stems. They have the ability to divide rapidly. |
|
| 32. |
All parts of the plant do not grow. Why? |
|
Answer» In plants, only the meristematic cells have the ability to divide and grow. Meristematic cells are mainly found in the root apex and stem apex. So the plant growth is concentrated at the root apex and stem apex. |
