The growth in plants is ____( )(a) limited to certain regions (b) uniform in all parts(c) limited to top region (d) limited to roots only

The growth in plants is primarily limited to certain regions, particularly the tips of roots and stems, which is referred to as apical growth. This means that option (a) "limited to certain regions" is the most accurate answer.

Explanation:

• Plants grow in specific areas due to the presence of meristems, which are regions of undifferentiated cells capable of division.
• Apical meristems are found at the tips of roots and stems, allowing for primary growth (increase in length), while other types of meristems contribute to secondary growth (increase in thickness) in specific areas.
• Therefore, unlike options (b), (c), and (d), which are either too broad or too restrictive, option (a) correctly reflects the overall pattern of plant growth.

In conclusion, the best answer is:

Final Answer

(a) limited to certain regions.
