Share & grow the world's knowledge!
We want to connect the people who have knowledge to the people who need it, to bring together people with different perspectives so they can understand each other better, and to empower everyone to share their knowledge.
How to Study Cells?
Cells are studied using microscopes, as they are smaller than the resolution limit of the human eye. Light microscopes provide basic magnification, while electron microscopes reveal detailed internal structures. Scientists prepare slides, stain cells and observe them under microscopes. These tools hRead more
Cells are studied using microscopes, as they are smaller than the resolution limit of the human eye. Light microscopes provide basic magnification, while electron microscopes reveal detailed internal structures. Scientists prepare slides, stain cells and observe them under microscopes. These tools help in understanding cell size, structure organelles and their functions effectively.

See lessWhat if mung bean seeds are kept in a concentrated solution after soaking in water for 12 hours? What will happen to them?
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.

See lessAll living organisms are made up of cells. Explain.
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 uniRead more
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.

See lessHow does a cell multiply?
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.
