Birds are important Since this is not a concern in the high humidity of tropical rainforests, most trees have a thin, smooth bark. A second type of lateral (nonapical) meristem, called the cork cambium, develops in some of the cells of the older phloem and forms cork cells. A type of transfer cell and supplied with many protoplasmic connections to the adjacent root cells, root hairs increase the absorbing area of the roots at minimal carbon cost and can penetrate finer pores in the soil. are often shallow and they grow tall to reach the sunlight. food and spices, for example, allspice, vanilla, cacao, cassava, ginger, bananas, black Most trees in the rainforest grow rapidly to escape the darkness of the forest floor and understory and to reach the needed sunlight of the canopy.
