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. Question: When the seed of a tree first starts to grow, what would happen if the cells did not differentiate?

Option 1: Other cells would differentiate.
Option 2: All of the cells would be identical.
Option 3: The seed could form roots, but not leaves.
Option 4: The DNA would make new cells.

Answer 1

If the cells in a seed did not differentiate, all of the cells would be identical and the plant would not be able to form specialized tissues or structures. Correct option is 2.

Step-by-step explanation:

If the cells in a seed did not differentiate, it would result in all of the cells being identical. This would prevent the formation of specialized tissues and structures within the growing plant. For example, without differentiation, the seed would not be able to form roots, leaves, or any other distinct plant parts. Each cell would essentially be the same, leading to a lack of diversity and functionality in the growing plant.
