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. when the seed of a tree first starts to grow, what would happen if the cells did not differentiate? o all of the cells would be identical. o the seed could form roots, but not leaves. o the dna would make new cells. o other cells would differentiate.

Explanation:

Cell differentiation is crucial for the development of different plant structures. If cells do not differentiate, the plant cannot form specialized tissues and organs. In a tree - growing context, undifferentiated cells would not be able to form roots, leaves, etc. Other cells differentiating is not the main consequence of non - differentiation at the start. DNA making new cells is not the main issue here as it is about the lack of differentiation. And the seed not being able to form different structures is the key problem. So the seed could form roots but not leaves is incorrect as it needs differentiation for both. Also, all cells being identical would be the case if there is no differentiation, and the plant cannot develop properly.

Answer:

All of the cells would be identical.
