the plant body is made up of the three types of tissue name and explain them in breif
Answers
Answer:
Explanation:
Plant body made up of Meristematic and permanent tissues.....
Meristematic tissues.....
These Meristematic tissues are continues state of division....
Hence, these meristem tissues stop dividing and changes into permanent tissues i.e, differentiation.
These Meristematic tissues divided into three types namely....
- Apical Meristem found in the tips of the plant bodies...
- Intercalary Meristem found in the middle parts of plants....
- Lateral Meristem found in the lateral (posterior) parts of parts...
Permanent tissues....
These tissues formed from meristematic tissues and classified into two types namely....
- Simple tissues (Parenchyma, Collenchyma, Sclerenchyma)
- Permanent tissues (Xylem, Phloem)
Parenchyma tissues....
Parenchyma tissues generally present in all parts of plants.
It constitutes the ground tissues in a plant.
It is a precursor of all other tissues.
It is a living tissue and made up of thin walled cells and cell wall is made up of cellulose.
It contains several types namely, Aeranchyma, Storage Parenchyma, Stellate Parenchyma and Chlorenchyma......
Collenchyma tissues.....
Collenchyma tissues generally occurs in dicot stems in two or more layers below the epidermis and constitute Hypodermis.
Absent in root of land plants.
Several types of collenchyma are Lamellar, Angular, Lacunate collenchymae.
Sclerenchyma tissues....
It is a dead tissues.
Have lignified secondary walls and don't contains protoplasts....
Types are Fibers and sclerieds.
