Chap 7 Terminology Crossword

A green pigment located within the chloroplasts of plants and algae and in the membranes of certain prokaryotes. Chlorophyll a participates directly in the light reactions, which convert solar energy to chemical energy.
The first of two stages in photosynthesis; the steps in which solar energy is absorbed and converted to the chemical energy of ATP and NADPH, releasing oxygen in the process.
Leaf cells specialized for photosynthesis; a leaf’s ground tissue system.
A fixed quantity of light energy. The shorter the wavelength of light, the greater the energy of a photon.
The production of ATP by chemiosmosis during the light reactions of photosynthesis.
The process by which plants, algae, and some protists and prokaryotes convert light energy to chemical energy that is stored in sugars made from carbon dioxide and water.
A light-capturing unit of a chloroplast’s thylakoid membrane, consisting of a reaction-center complex surrounded by numerous light-harvesting complexes.
A microscopic pore surrounded by guard cells in the epidermis of a leaf. When stomata are open, CO2 enters a leaf, and H2O and O2 exit. A plant conserves water when its stomata are closed.
The dense fluid within the chloroplast that surrounds the thylakoid membrane and is involved in the synthesis of organic molecules from carbon dioxide and water. Sugars are made in the stroma by the enzymes of the Calvin cycle.
A flattened membranous sac inside a chloroplast. Thylakoid membranes contain chlorophyll and the molecular complexes of the light reactions of photosynthesis. A stack of thylakoids is called a granum.
