What is newton's law ? |
|
Answer» Answer: In classical mechanics, Newton's laws of MOTION are three laws that describe the relationship between the motion of an object and the forces acting on it. The FIRST law states that an object either remains at rest or continues to move at a constant velocity, unless it is ACTED upon by an EXTERNAL force.[1] The second law states that the rate of change of momentum of an object is directlyproportional to the force applied, or, for an object with constant mass, that the net force on an object is equal to the mass of that object multiplied by the acceleration. The third law states that when one object exerts a force on a second object, that second object exerts a force that is equal in magnitude and opposite in direction on the first object. The three laws of motion were first compiled by Isaac Newton in his Philosophiæ Naturalis Principia Mathematica (Mathematical Principles of Natural Philosophy), first published in 1687.[2] Newton used them to explain and investigate the motion of many physical objects and systems, which laid the foundation for Newtonian mechanics |

Can anyone give the summary of what is Parenchyma tissue and it's structure and functions from ncert class 9 book |
|
Answer» PARENCHYMA. Consist of live unspecialized cells having thin CELL wall. They are loosely packed and have large INTERCELLULAR space (space between the cells). Provides support to the plant and PRESENT in all parts like roots, stems, leaves, fruits and seeds. Parenchyma tissue is composed of thin-walled cells and makes up the PHOTOSYNTHETIC tissue in leaves, the pulp of fruits, and the endosperm of many seeds. Collenchyma cells mainly form supporting tissue and have irregular cell walls. They are found mainly in the cortex of stems and in leaves. |

|
Answer» Explanation: Bacteria are SINGLE celled microbes. The cell structure is simpler than that of other organisms as there is no nucleus or membrane bound ORGANELLES. Instead their control centre containing the genetic information is contained in a single loop of DNA. Some bacteria have an extra circle of genetic material called a plasmid. The plasmid often contains genes that give the BACTERIUM some advantage over other bacteria. For example it may contain a gene that makes the bacterium RESISTANT to a certain antibiotic. Bacteria are classified into five groups according to their basic SHAPES: spherical (cocci), rod (bacilli), spiral (spirilla), comma (vibrios) or corkscrew (spirochaetes). They can exist as single cells, in pairs, chains or clusters. |

Draw , label & describe the following methods of vegetative propagation in horticultural practices: |
|
Answer» Answer: Vegetative propagation is accomplished by use of (1) apomictic seed, (2) specialized vegetative structures such as runners, bulbs, corms, rhizomes, offshoots, tubers, stems, and ROOTS, (3) LAYERS and cuttings, (4) grafting and budding, and (5) TISSUE culture. Explanation: Vegetative Propagation by Stems Stems that grow horizontally on the ground are called runners. As these runners grow, buds form at the nodes, which later develop the roots and shoots, resulting in the formation of a new plant. Example – Cyanodon; Mint etc. The bulb is the round, swollen PART of the underground stem. |

What are cells. why are they called structural and functional unit of life |
|
Answer» Answer: A cell is the smallest, basic unit of life responsible for all of life’s processes. Cells are the structural, functional, and biological units of all LIVING beings. A cell can replicate itself independently. Hence, they are KNOWN as the building blocks of life. The functional unit of life The cell is our most ESSENTIAL body forming unit. Each organ in our body is made of cells. Cells divide and multiply to form new organs and gametes too. Due to the below-mentioned REASONS, the cell is called a functional unit of life. The cell is called the structural and functional unit of life as all living organisms are made up of cells. Cells are also essential for performing various life processes required for SUSTAINING life. Furthermore, cells provide form and structure, process nutrients and convert them into useable energy. Multicellular organisms have specialized cells that perform specific functions. |
