Column A Column B 1. Dark phase. c. Glucose production 2. Centrioles. e. Aster 3. Sex chromosomes. a. Allosomes 4. Chlorophyll synthesis. g. Magnesium 5. The ascent of sap. b. Xylem 1. Dark phase reactions are the reactions which can occur in the absence of sunlight, which result in glucose production. 2. Sex chromosomes are a typical pair of mammals allosomes which determine the sex of individuals. 3. Centrioles are present at the poles of cells from which ray-like asters form to separate chromatids. 4. Chlorophyll synthesis requires the presence of magnesium.Without magnesium chlorophyll can not capture sunlight needed for photosynthesis. 5. The ascent of sap is the rising of water and minerals in the plant which happens in the xylem.
