Plants cell
difficult words for exchange student
cell membrane:
the thin layer of protein and fat that surrounds the cell. The cell membrane is semipermeable, allowing some substances to pass into the cell and blocking others.
centrosome:
a small body located near the nucleus - it has a dense center and radiating tubules. The centrosomes is where microtubules are made. During cell division (mitosis), the centrosome divides and the two parts move to opposite sides of the dividing cell. The centriole is the dense center of the centrosome.
cytoplasm:
the jellylike material outside the cell nucleus in which the organelles are located.

what do plants cell do?
Cell membranes serve for the same purpose in all cells. They control what enters and leaves a cell while providing structural support and protection. See "What is a cell membrane?"
The cell membrane in the plant cell is mainly used to regulate gas exchange and water flow.
the outer bpunday of the cell is the cell membrane also called the plasma membrane or plasmalemma

function
- physical isolation: the cell membrane is a physical barrier that separates the inside of the cell from the surrounding extrecellular fluid. conditions inside and outside the cell are very different, and those differences must be maintained to preserve homeostasis. For example. the cell membrane keeps enzymes and structurral proteins inside the cell.
- Regulation of exchange with the envirionment. the cell membrane controls the entry of ions and nutrients, such as glucose the elimination of wastes and the release of secretions.
why is the plan's cell important to the cell?
Plant cells are eukaryotic cells. As living organisms go, a eukaryote versus a prokaryote has cells with a more sophisticated internal anatomy. In a eukaryotic cell, there is an array of structures termed organelles. These are subcellular features, including a nucleus and various other components that make the cell functional. In comparison, bacterial cells are classified as prokaryotic. The prokaryotic cell lacks most of the internal structure, including the well-defined nucleus present in eukaryotic cells. Plant and animal cells share many characteristics, but at least two features distinguish plant cells.
