Answer 1

meristimatic tissues at the tissues which are capable of dividing.

they are present in young ,protective parts of plant and are present in growing parts of plant

Answer 2

1.)Aerenchyma refers to spaces or air channels in the leaves, stems and roots of some plants, which allows exchange of gases between the shoot and the root. Chlorenchyma refers to Plant tissue consisting of parenchyma cells that contain chloroplasts and forming the basic green tissue of plant leaves and stems.

2.)Intercalary meristemLateral meristemIt is an area of actively dividing cells located at the internodes.It is an area of actively dividing cells located at the lateralsides of the stem and the root.It is found at the internodes and base of the leaves.It is found at the lateral surface of the roots and the stems
