Summary Introduction

Introduction:

The plants are the multicellular organisms that perform their functions and complete their life cycle. The plant starts forming from a seed and develops into a completely grown plant.

Answer to Problem 1U

Correct answer:

The development of growth forms is called the morphogenesis. Therefore, option a. is correct.

Explanation of Solution

Reason for the correct statement:

The development of the shape of an organism through different stages is called morphogenesis. The morphogenesis in the plants is the series of developmental changes that form the plant by the differentiation and organization of the cells.

Option a. is given as “growth form”.

As, “the morphogenesis is the developmental changes occurring in the plants, due to which the plants grow and functions properly”, is the right answer.

Hence, the option a. is correct.

Reasons for the incorrect statements:

Option b. is given as “reproductive structures”.

The reproductive development is known as the process of the development of the reproductive structures in the organisms. So, it is a wrong answer.

Option c. is given as “a phase change”.

The change in the phase in the plants is the transitional change to develop into a reproductive form from a vegetative form. So, it is a wrong answer.

Option d. is given as “meristems”.

In the embryogenesis, the apical meristems of the roots and shoots develop and differentiate to form the distinctive types of tissues in the plant. So, it is a wrong answer.

Hence, options b., c., and d. are incorrect.

Conclusion

The development of the growth forms of the plants is called morphogenesis.
