Question

The period between the formative phase and maturation phase of plant growth is
(a)Lag phase
(b)Phase of elongation
(c)Stationary phase
(d)Grand period of growth

Answer 1

Hint: Development in plants is divided into three main phases, namely cell division, cell elongation, and cell maturation phases. The formative stage is also called the cell division process.

Complete answer:
-New cells are formed by meristematic tissue having mitotic divisions during the formative phase.
-The cell division process is also known as the formative phase. It is the first step for multicellular organisms to evolve.
-Mitosis is the type of division of cells that is necessary for an organism's development. It includes nucleus division (karyokinesis) as well as cytoplasm (cytokinesis) division.
-During this stage, different mitosis phases such as prophase, metaphase, anaphase, and telophase are passed by the cell.
-The stage of elongation is the transitional stage between the formative phase and the maturation phase.
-The cell enlargement process involves the synthesis of further protoplasm amounts, hydration, the addition of material from the cell wall, etc. This is because of the rise in tissue and organ size.
-The development of special types of cells by structural and physiological differentiation is a stage of maturation or differentiation.
-The cell differentiation stage or the cell maturation process in which the cell is specialized for a role. To carry out particular roles, cells are organized into tissues.
So, the correct answer is ‘Phase of elongation’

Note: -Temperature: Within a temperature range, plants grow. Too low or too high temperatures hinder plant growth.
-Light: For growth, optimum light is required. And some plants require ample sunlight for flowering to occur.
-Water: For the growth of plants, sufficient water is required.
-Oxygen: Plants often require oxygen for respiration and for other tasks to be carried out.
-For plant growth and development, mineral nutrients are also important.
