Phases of Plant Growth
Plant growth consists of three phases, which are as follows
Formative or Meristematic Phase
The meristematic zone, which is found at the tip of a plant’s root and consists of continually dividing, isodiametric (with no intervals between the cells) meristematic cells, is also characterized by cells with rich protoplasm and a prominent nucleus. These cells’ cellulose-based cell walls are thin, primary in nature, and of a primary nature. These cells are connected by white plasmodesmata.
This area of the plant’s cells continues to divide rapidly. Typically, a big nucleus makes up the plant’s meristematic area. the cells needed to promote a plant’s initial growth phase. All plants have them in their roots and branches.
Elongation Phase
The cells present next to meristematic cells are present in the elongation phase. These cells elongate due to enlargement of the vacuole present in the cell and hence that zone is called the zone of elongation. Cell enlargement and new cell wall formation take place in the cells present in the elongation phase. Modifications like larger vacuoles take place in the cells here.
Maturation Phase
The cells discovered after the elongation zone are in the maturation phase and reach their largest size. When they reach the maturity period, they stop dividing. Cells develop in large numbers throughout the zone of maturation to carry out specific tasks in plants.
Differentiation, Dedifferentiation and Redifferentiation in Plant Growth
Plant growth is dependent on three major factors that are differentiation, differentiation, and differentiation. The kingdom Plantae is home to a variety of unique living things, including plants. They exhibit a variety of distinguishing animal traits. They are independent due to their unique cell structure and organelles. Additionally, plants grow taller and bigger with time, just like people and animals do. They differ in how they grow and go through their life cycle, further details are discussed below. Growth is a crucial, natural, and irreversible element. Every plant grows since it is a living thing, however, unlike people, plants have particular growth characteristics. They develop over the course of their lives. Plant growth happens in a planned way. Development in plants is referred to as this methodical approach to growing. The constant, irreversible expansion of an organism’s size is referred to as growth. The presence of various metabolic processes together with this characteristic is seen in all species. The seeds of plants develop, grow into new seedlings, and then mature plants. Growing continues forever in plants. Plants grow in an open, indeterminate manner, and certain cells continually divide to contribute to the expansion of the cell or tissue’s size. Meristematic cells are characterized by their constant division. Since there is an increase in protoplasmic content, plant growth may be measured. Along with these additional changes, which can all be quantified, fresh or dry weight, length and size, and cell count all increase.
