What part of the cell helps maintain a stable environment?
But the cell membrane contains channel proteins that only water molecules can pass through. Osmosis allows cells to maintain water balance as their environment changes. When ions and polar substances dissolve in water, they attract and bind some water molecules. The remaining water molecules are free to move around.
How does the inside of a cell remains separate from its environment?
cell has cell membrane (also known as the plasma membrane or cytoplasmic membrane) it is a biological membrane that separates the interior of all cells from the outside environment. The cell membrane is selectively permeable to ions and organic moleculesand controls the movement of substances in and out of cells.
What are three things all cells must do to maintain homeostasis?
the maintenance of a constant internal state in a changing environment. What are four things that cells can do to maintain homeostasis? obtain and sue energy, make new cells, exchange materials and eliminate wastes.
What is structures that converts nutrients to energy?

What are the four function of cell division?
Answer: (1) the reproduction of an entire unicellular organism, (2) the growth and repair of tissues in multicellular animals, (3) the formation of gametes (eggs and sperm) for sexual reproduction in multicellular animals.
What are the four results of cell division?
Mitosis takes place in four stages—prophase, metaphase, anaphase, and telophase—during which each chromosome copies itself, the nucleus divides in two, and the whole cell splits into two identical daughter cells. Each new cell receives a set of chromosomes identical to those of the original cell.
What are some results of cell division?
Terms in this set (4)
- Reproduction. In some unicellular organisms, cell division is a form of asexual reproduction.
- Growth. Cell division allows multicellular organisms, such as humans, to grow and develop from one cell (fertilized egg).
- Replacement. Even after an organism is fully grown, cell division continues.
- Repair.
What are results of cell division?
In cell biology, mitosis (/maɪˈtoʊsɪs/) is a part of the cell cycle, in which, replicated chromosomes are separated into two new nuclei. Cell division gives rise to genetically identical cells in which the total number of chromosomes is maintained.
What are the two results of a cell completing the cell cycle?
Cells on the path to cell division proceed through a series of precisely timed and carefully regulated stages of growth, DNA replication, and division that produces two identical (clone) cells.
What is the longest mitosis stage?
Prophase
In which phase does the cell spend the least amount of time?
Root tip cells spend the least amount of time in which phase(s)? Metaphase and anaphase; these stages are intermediary steps where the chromosomes line up and then separate. There is little preparation required for these phases. Why do you think scientists use the root tip to study mitosis?
