Document Summary
Growth- increase in size through cell division and enlargement. Differentiation- cells adapting to take on different functions. Morphogenesis- an organism develops into a certain shape. Development- the result of growth, differentiation and morphogenesis. Guard cells allow evapotranspiration to occur to regular water levels. Trichomes are hair-like structures which lower leaf temperature and absorb com- pounds. A thin cell layer which be covered with a cuticle. Parenchyma are found throughout the plant for metabolic functions. Collenchyma are in primary cell walls to provide structure, just under the epidermis. Sclarenchyma are long tissues and part of the vascular system. Xylem are highly lignified and transport water and minerals. Phloem transport sugars for storage in the plant. Apical meristems are found at root and shoot tips. Secondary growth is the growth from secondary meristems.
