plant’s interaction with its environment. The main carbon source (carbon dioxide) needs to be solubilized in the apoplast before it is taken up by chloroplasts and consumed during photosynthesis. In the roots‚ ions diffuse into the apoplast of the epidermis before being taken up into the symplast by specific ion channels and being pulled by the plant’s transpiration stream‚ which also occurs completely within the boundaries of the apoplast. Similarly‚ all gaseous molecules emitted and received by plants

The three basic organs of a vascular plant are the stems‚ leaves‚ and roots. The stems consist of nodes‚ where leaves attach‚ and internodes between the nodes. The stem is responsible for elongation of the plant and acts as a central axis for other organs to attach to. The roots help to anchor the plant as well as absorb water and nutrients

loss in humidity as well as a decrease in activity of the sebaceous and sweat glands. Primarily‚ changes in the skin’s appearance are a result of a general aging process of the connective tissue of the subcutis. This leads to an atrophy of the epidermis which adjoins the papillary layer and to an irregular decrease in the elasticity of the elastic nets which are structures accompanying the collagen fibres in the connective tissue. As a result of the changed amount and chemical composition

Case Study 1 1. Briefly describe the three major layers of skin that make up healthy skin The three layers that make up healthy skin: Epidermis‚ Dermis and Hypodermis. Epidermis is composed of keratinized‚ stratified squamous epithelium. This layer provides a thick‚ water proof protective covering over the underlying skins. The dermis layer is composed of primarily of dense‚ irregular‚ fibrous connective tissue that is rich in collagen and elastin. The dermis contains blood vessels‚ nerve ending
