The cells that conduct water in plants are tracheids or vessel members, both of which make up the plant tissue known as xylem. The type of cell predominant in xylem depends on the type of plant, but most species in all groups have at least some tracheids.Know More
Tracheids are the only types of cells that conduct water in seedless vascular plants, such as ferns, and most gymnosperms, such as pine trees. Tracheids are narrow and elongated hollow cells. They have thin, modified cell walls known as pit membranes. The membranes permit passage of water between vessels while protecting against damaging air bubbles.
Vessel members are very similar in basic shape to tracheids, but they are even more specialized to carry water efficiently. Instead of pit membranes, they have perforations, which are areas that lack both a cell wall and a cell membrane. These allow water to pass very easily between cells, but they provide less protection against air bubbles. As a result, the cells are more likely to suffer fractures and disruptions. Vessel members are the primary cells in the xylem of flowering plants.
Both types of cells are accompanied by fiber cells that provide structural support. In woody plants, the cells that make up xylem tissue form rings, with only the outermost ring living, and the rest provide support for the plant.Learn more about Cells
Water is important to cells because without it they would not be able to remove waste, bring in nutrients or transport oxygen. The body is a very intricate system where many parts rely on each other. Without the cells being able to perform or move oxygen around the body, death would be quick to follow the loss of the water.Full Answer >
The cheek cells, also called epithelium cells, are responsible for maintaining moisture in the oral cavity which in turn aids in digestion, softening food for consumption and facilitating swallowing. Cheek cells constantly produce a flow of muicin, which is the main part of mucous. The cheeks cells divide every 24 hours and are shed rapidly from the body.Full Answer >
Some of the main functions of skin cells are to provide protection, perceive and transmit sensation, control evaporation and regulate temperature. Skin cells, which are epithelial cells, are also self-repairing and reproduce quickly. Epithelial cells are the most commonly found of the four tissue types.Full Answer >
Plant cells divide through the process of mitosis, followed by cytokinesis. Mitosis in plant cells is similar to mitosis in animal cells, which occurs in four stages: prophase, metaphase, anaphase and telophase.Full Answer >
