Question

What specialized tissues function in primary and secondary growth in plants?

Answer 1

Primary growth in plants is mediated by the apical meristem located at the top of the plant shoot or the bottom of the root. It provides an increase in the length of the shoot and root. The lateral meristem is involved in the secondary growth mediating the increase in the thickness of the plant. Secondary growth also depends on the cork cambium and vascular cambium that contain cells undergoing extensive proliferation.
