Answer 1

Answer:

3] [a] Permanent tissue . Xylem is a complex permanent tissue which is a type of permanent tissue . It helps in conduction of water from roots to shoots. 4] [c]Mechanical support . Sclerenchyma is a dead tissue so it provides mechanical support to plant .5] [c] 3 types. The three types of Meristematic tissues are :- Apical Meristem , Lateral Meristem and Intercalary Meristem . 6] [c] Apical Meristem . Apical Meristem is found in shoot and root tips of plants. 7][b] Ground Tissue . Parenchyma forms the ground tissue . 8] [b] Collenchyma . Collenchyma is unequally thickened . 9] [a] Sclerenchyma . Sclerenchyma is a dead tissue . It provides mechanical support to the plant . 10] [b] Xylem . Xylem helps in conduction of water in plants in one way direction [unidirectional] from roots to shoots .
