what are the types of MERISTEMATIC tissues ?
apical and lateral
lateral ,intercalary, apical
xylem and phloem
sclerenchyma ,parenchyma and collenchyma
inter-nodal growth in a plant is due to
intercalary meristem
apical meristem
permanent tissue
lateral meristem
why do meristematic tissues have large nucleus
as to store food
as it should have big brain
as it helps in dividing continuously
it has to protect
a chemical present in the cork/bark of plant .
chlorophyll
suberin
serum
impulse
true/ false- growth in height of roots and stem is due to lateral meristem and growth in width is due to apical meristem
TRUE
FALSE
