how do cells come in water

Cells are microscopic living units found in nearly all organisms. They are surrounded by a cell membrane, which acts as a barrier between the cell and its surroundings. In the case of aquatic organisms, the cells are already in contact with water.

In multicellular organisms, such as plants and animals, cells are organized into tissues, organs, and systems. They receive water through specialized structures, like roots in plants or gills in aquatic animals. These structures are designed to absorb water and nutrients from their environment.

In single-celled organisms, such as bacteria or single-celled algae, cells may have specialized structures called contractile vacuoles or pores that allow them to take in water by osmosis or actively pump it in.

Regardless of the organism's complexity, cells rely on water for various processes, such as maintaining their shape, transporting nutrients and waste, facilitating chemical reactions, and participating in cellular respiration. Water is crucial for cell survival and plays a vital role in supporting life.
