Concept explainers
To analyze:
The structure and function of roots, stems, and leaves.
Introduction
Root is a structure of plant present underground. It has an epidermal covering which contains root hair. It has vascular bundles (xylem and phloem). The function of the root is to provide anchorage to plant, absorb water and minerals from the soil. Roots are nonphotosynthetic.
The stem is a structure present above the ground. It also has epidermis, but hairs are rare. It has vascular bundles (xylem and phloem). Photosynthesis can occur in some cells of the stem. The function of the stem is to provide support to plant.
Leaves are the green structures of plant present on the stem and its lateral branches. The function of leaves is to perform photosynthesis and allow the exchange of gases required by plants.

Please note that the focus of this assignment are the (biological) scientific issues associated with rewilding. As will be discussed in class, there are a number of non-scientific issues involved or implicated in rewilding, all ultimately affecting the public acceptability of rewilding. Although these issues are important – indeed, critical – in this assignment you should focus on the biological science issues and questions. Details: You must enumerate at least two pros and at least two cons. Your answer should be no more than 500 well-chosen words, excluding references. Think carefully about how best to organize and structure your answer. Aim for high information density: say a lot, but say it succinctly. Recall Nietzche’s…arrow_forward
