Question

how cells are used in the body quick check
which of the following is true about cell differentiation when the body tries to heal from an injury? (1 point)
○ stem cells differentiate to provide specialized cells that replace damaged tissue.
○ platelets express different sections of rna in order to create skin cells.
○ cells grow during the synthesis phase of the cell cycle in preparation for senescence.
○ damaged cells proliferate until the wound heals.

Explanation:

Stem cells have the ability to differentiate into various specialized cell types. When the body is healing from an injury, stem cells differentiate to form the specific types of cells (such as skin cells, muscle cells etc., depending on the injured tissue) that are needed to replace the damaged tissue. Platelets are involved in blood - clotting, not in creating skin cells. The synthesis phase of the cell cycle is for DNA replication, not directly related to cell differentiation for injury repair. Damaged cells do not proliferate in a healthy repair process; instead, new cells (often from stem - cell differentiation) replace them.

Answer:

Stem cells differentiate to provide specialized cells that replace damaged tissue.
