1. When soaked mung bean seeds are placed in a concentrated solution, water moves out of the cells due to osmosis. The surrounding solution has higher solute concentration, causing water loss from seeds. This leads to shrinking of cells and reduction in size. The seeds become flaccid and lose their swoRead more

    When soaked mung bean seeds are placed in a concentrated solution, water moves out of the cells due to osmosis. The surrounding solution has higher solute concentration, causing water loss from seeds. This leads to shrinking of cells and reduction in size. The seeds become flaccid and lose their swollen condition due to water loss.

    According to cell theory, all living organisms are made up of one or more cells. Unicellular organisms perform all life functions within a single cell, while multicellular organisms have many specialised cells. These cells organise into tissues organs and systems. Thus, cells are the fundamental units that make up every living organism, from bacteria to humans.

    Technological advancements, especially microscopes, have helped scientists study cells that are too small to be seen by the naked eye. Light microscopes provide magnified images, while electron microscopes reveal fine details at the nanometre scale. Improvements in resolution, contrast and magnification have made it possible to understand cell structure organelles and their functions in great detail.

  4. Cells multiply by a process called cell division. The parent cell divides into daughter cells through mitosis or meiosis. Mitosis produces identical cells for growth and repair, while meiosis produces gametes for reproduction. This process ensures continuity of life, increases cell number and replacRead more

    Cells multiply by a process called cell division. The parent cell divides into daughter cells through mitosis or meiosis. Mitosis produces identical cells for growth and repair, while meiosis produces gametes for reproduction. This process ensures continuity of life, increases cell number and replaces damaged or dead cells in the body.

    The cell is the structural unit as all organisms are made of cells that form tissues and organs. It is the functional unit because all vital processes such as respiration, nutrition, excretion and growth occur within cells. Each cell performs necessary life functions independently or in coordination, making it essential for survival and functioning of living organisms.
