Question

Classify the types of plant tissues???​

Answer 1

Answer:

The epidermis, ground tissue, and vascular tissue are the three major tissue systems that make up plant tissues.

Explanation:

• Plant Tissue Classification: According to Where They Are Located in the Plant

1. Epidermal tissues: A single layer of cells covering the surface of a plant.
2. Ground tissues are what a plant uses to cover its insides.
3. Transports water and other dissolved materials inside the plant through vascular tissues.

• Plant Tissue Classification - Based on the type of cells that are present.

1. Meristematic - This category includes three main categories.
2. Permanent: This category includes the Simple and Complex major kinds. The three types of simple include parenchyma, collenchyma, and sclerenchyma. The complex is further separated into the Xylem and Phloem type groups.

Answer 2

Answer:

Plant tissues provide structural strength to the plant body as they are immobile and help to pass unfavorable environmental conditions like storms, floods, strong winds, etc.

Plant tissues are of two types; meristematic and permanent.

Meristematic tissue - This tissue helps in the major growth of the vegetation, and the growth in diameter and length of the plant. The meristematic cells are cubical with a big nucleus, and there are no intercellular spaces between these cells. These tissues are developed by swift division. They are categorized into three types; apical, lateral, and intercalary, based on the existing section of meristematic tissues.

• Apical meristem -  This is at the growing tips and apical of roots and stems. This helps to grow the length of the plant.
• Lateral meristem - This is at the radial portion of the root or stem. This helps to grow the thickness of the plant.
• Intercalary meristem - This is at the internodes or the base of the leaves. This helps in the growth of the internode size.

Permanent tissue - These tissues are specialized to provide strength, elasticity, and flexibility to the plant. These are of two types; simple and permanent.

• Simple permanent tissue - This is of three types; parenchyma, collenchyma, and sclerenchyma. Parenchymatous cells are polygonal in shape with a big centriole. The cells of parenchyma tissue have intercellular spaces. These cells create pith and ground tissue. Collenchymatous cells are stretched out with minute intercellular spaces. This is at the marginal region of the stem and leaves and provides mechanical support and flexibility to the plant. Sclerenchymatous cells are dead, elongated and lignin is deposited on their cell walls. They have no intercellular spaces and are present in the covering of seeds and nuts, and around the vascular tissues in the stem and veins of leaves. These provide strength to the plants.
• Complex permanent tissue - This includes xylem and phloem. Xylem is involved in the transport of water in the plant and is made up of xylem parenchyma, vessels, tracheids, and fibers. Phloem is involved in the transport of food in plants and is made up of phloem fibers, phloem parenchyma, companion cells, sieve cells, and sieve tubes.
