Growth : The quantitative increase in plant body is called growth.
Meristem: Meristents are young tissues or group of cells that retain the potential to divide.
Apical Meristems: The meristems present at the tips of roots and shoot are called apical meristems.
Meristems: The meristem situated at the bases of internodes is called intercalary meristem.
Lateral Meristems: The cylinders of dividing cells present in the vascular and cork tissue of the plants are called lateral meristems.
Primary Growth: In this growth. primary tissues are added by the apical meristem. It increases
the length of the plant.
Secondary Growth: In this growth, secondary tissues are added by the intercalary or vascular cambium. It increases the thickness of plant.
||The special substances produced by the plants
which influence the growth and plant responses are
called plant hormones. ,
||The phenomenon in which shoot apex inhibits the growth of lateral buds is called apical dominance.
||The falling of leaves, flowers and fruits is called abscission.
||The bending of plant organs like coleoptile. stem and root toward or away from stimulus due to unequal growth is called tropism.
||The physiological inability of a seed to grow is
called seed dormancy.
||The plants with very short stem and crowed leaves are called rosette plant.
||The rapid stein elongation of rosette plant is called bolting.
||The start of fruit growth after pollination is called fruit setting.
||The differentiationof different tissueslike root.
shoot from callous is called morphogenesis.
||The degradative changes which lead to death of an organ or organism are called leaf senescence.
||The in vitrocultivation of any partof plant in
nutrient medium is called tissue culture.
||An undifferentiated group of cells is called callus.
