Document Summary

Chapter 31 - plant growth and development (part 2) The first vascular plants lacked roots and only survived in very wet environments in which they could absorb water from horizontally submerged stems. Roots grow by producing new cells at their tips. Root elongation and vascular development are coordinated. The formation of new root apical meristems allows roots to branch. New meristems develop from the pericycle, which is adjacent to the vascular bundle, meaning that the new root meristem develops internally and the new root grows through the endodermis, cortex, and epidermis before reaching the soil. New roots can be produced by stems. The structure and functions of root systems are diverse. 31. 5 the environmental context of growth and development. Plants gain information from their surrounding environment by relying on photoreceptors, mechanical receptors, and chemical receptors. Plants orient the growth of their stems and roots by light and gravity.
