The absorption spectrum of a plant shows what wavelengths of light the plant absorbs. The absorption spectrum depends on A. the number of stomata in the plant leaves B. the wavelengths of light that hit the plant. C. wavelengths of light that are reflected by the plant. D. the thickness of the plant's leaves. E. wavelengths of light to which the plant's pigments respond. 3.

5. When a plant cell, such as one from a peony stem, is submerged in a very hypotonic solution, what is likely to occur? A. the cell will become turgid B. the cell will burst C. the cell will become flaccid D. the cell membrane will lyse E. plasmolysis will shrink the interior 6. In facilitated diffusion, what is the role of the transport protein? A. Transport proteins provide a hydrophilic route for the solute to cross the membrane. B. Transport proteins organize the phospholipids to allow the solute to cross the membrane. C. Transport proteins provide a low-resistance channel for water molecules to cross the membrane. D. Transport proteins provide the energy for diffusion of the solute. E. Transport proteins provide a protein site for ATP hydrolysis, which facilitates the movement of a solute across a membrane. 7. Atoms can be represented by simply listing the number of protons, neutrons, and electrons - for example, 2 p + ; 2 n 0 ; 2 e - for helium.
