Some cells in multicellular organisms are constantly dividing. What is one reason why cells divide?
Cells divide to make new cells.
the environment within the cell is stable
to replace dead or damaged skin cells
Many chemical reactions in the cell will slow down or even stop.
so that an organism can grow by adding new cells
eliminating waste
the maintenance of a stable internal environment
loses its leaves
Cells can die or become damaged. What cell process replaces dead or damaged cells?
Cells divide to make new cells.

In one type of cell division, a single cell forms two new cells. This process is called mitosis. What is a reason that human skin cells frequently undergo mitosis?
Cells divide to make new cells.

Organisms can respond to changes in their environment in order to maintain homeostasis. What does a tree do to maintain homeostasis during the winter months?
Cells divide to make new cells.

Homeostasis is necessary for a cell to survive. What is the definition of homeostasis?
Cells divide to make new cells.
the environment within the cell is stable
to replace dead or damaged skin cells
Many chemical reactions in the cell will slow down or even stop.

The survival of a cell depends on the cell maintaining homeostasis. What is most likely to happen to a cell if homeostasis is not maintained?
Cells divide to make new cells.
the environment within the cell is stable
to replace dead or damaged skin cells
Many chemical reactions in the cell will slow down or even stop.
