Tissues are categorized as
plant tissue and animal tissue

meristematic tissues and permanent tissues
simple permanent tissues
parenchyma, collenchyma, sclerenchyma, epidermis
complex permannent tissue
xylem and phloem
mainly consists of actively dividing cells, and helps in increasing the length and thickening the stems of the plant

merismatic tissue
Depending on the region, merismatic tissues are classified as
apical, lateral and intercalary
present at the growing tips of stems and roots and helps in their growth
apical meristem
found in stem or root region and helps in their growth
lateral meristem
found at the base of the leaves or internodes (on twigs) and helps in growth
intercalary meristem
cells of merismatic tissue later differentiate to form
different types of permanent tissue
permanent tissue is further categorized as
simple permanent tissue and complex permanent tissue
