Question

read the passage to answer the question. have you had the chance to watch a tree grow over a span of several years? did you notice that the tree grew thicker and taller? deep in the roots of the tree and high in the growing shoots are meristem cells. each year, the meristem cells help the tree continue to grow. which process is most critical for different types of tree cells to develop? mitosis cell differentiation sexual reproduction dna replication

Explanation:

Cell differentiation is the process by which unspecialized cells (like meristem cells in trees) become specialized into different types of cells with specific functions. Mitosis is cell division for growth and repair but doesn't explain cell - type development. Sexual reproduction is for creating offspring. DNA replication is for copying DNA before cell division. Since the question is about different types of tree cells developing, cell differentiation is key.

Answer:

cell differentiation
