Question

Question 2 Why is not any one parameter good enough to demonstrate growth throughout the life of a flowering plant?

Class XI Biology Chapter - Plant Growth and Development Page 253

Answer 1

Hi friend,

There are different organs of a plant like roots, stems, leaves, flowers, etc. All these have different stages of life cycle. So, these organs require different parameters to demonstrate their respective growth. Hence, measuring or demonstrating the growth of plant using only one parameter cannot provide enough information about the plant's growth and is therefore not good enough.

Hope it helps!

Answer 2

Answer:

In plants, growth is said to have taken place when the amount of protoplasm increases.

Measuring the growth of protoplasm involves many parameters such as the weight of the fresh tissue sample, the weight of the dry tissue sample, the differences in length, area, volume, and cell number measured during the growth period.

Measuring the growth of plants using only one parameter does not provide enough information and hence, is insufficient for demonstrating growth.
