Outside of the cell B. Cytoplasm C. Hydrophobic region D. Hydrophilic region E. Protein F. Phospholipid bilayer A hydrogen bond is formed when a hydrogen atom is shared between at least ______ water molecules creating electrostatic attractions resulting in very strong intermolecular interactions. -Ans>> 2 What is the second most common organic compound? -Ans>> Lignin The endoplasmic reticulum is important to ____________________ formation. -Ans>> Protein At maturity, these types of simple cells are dead and are most often associated with xylem or vascular tissue. -Ans>> Sclerenchyma Hydrophobic interactions of a cell membrane can be described as nonpolar molecules that cannot form ___________ bonds with water. -Ans>> Hydrogen. These 3 main ares make up the plant cell: Cell wall, protoplast and __________________. -Ans>> Vacuole A single cell layer thick sometimes with a waxy coating best describes the _____________________? -Ans>> Epidermis The cell wall is made up of the primary and secondary wall, both of which are primarily composed of _________________ and _________________. -Ans>> Cellulose and lignin Identify the type of meristematic tissue in the image below. -Ans>> Apical root meristem Sucrose is composed of? -Ans>> Glucose and fructose This diagram features a cross section of a dicot stem.
