what happen to the cell formed by meristematic tissue
The cell have tensile strength . The cell doesn't capable for storage. The is very weak.
When meristematic tissue divides, it produces new cells. These newly formed cells have the ability to differentiate into various specialized cell types. Depending on their location within the plant, these cells will undergo different development processes:
1. Apical meristems: These are located at the tips of the roots and shoots. The cells produced by apical meristems contribute to primary growth, increasing the length of roots and shoots.
2. Lateral meristems: These are found on the sides of stems and roots, and they contribute to the increase in girth of the plant. The two main lateral meristems are vascular cambium (produces secondary vascular tissue) and cork cambium (produces the protective outer bark).
3. Intercalary meristems: These are present at the base of the leaf, at the nodes of grass, and within the internodes of some monocots. They contribute to the elongation of specific parts of the plant.
Now, let's move on to your second question about the differences between simple and complex permanent tissue:
1. Simple permanent tissue: This tissue consists of a single type of cells with a similar structure and function. It can be divided into three types:
a. Parenchyma: It is a living tissue that makes up the basic structural framework of plants. It is usually involved in photosynthesis, storage, and secretion.
b. Collenchyma: It provides mechanical support to the young parts of the plant. The cells are elongated, irregularly thickened, and occur in strands or patches.
c. Sclerenchyma: It provides mechanical support to mature parts of the plant. The cells have thick lignified cell walls and can be either fibers or sclereids.
2. Complex permanent tissue: This tissue consists of different types of cells with distinct functions working together. It includes two main types:
a. Xylem: It transports water, minerals, and provides mechanical support. It contains vessels or tracheids (long, tubular cells) and xylem fibers (providing structural strength).
b. Phloem: It transports food materials, mainly sugars, throughout the plant. It consists of sieve elements (sieve tube elements and companion cells) and phloem fibers (providing support).
In summary, meristematic tissue gives rise to new cells, which can differentiate into various specialized cell types. Simple permanent tissue consists of parenchyma, collenchyma, and sclerenchyma, while complex permanent tissue includes xylem and phloem.
