D11 25, 20I8 Please select best possible response 1. Fill in the blanks a paper chromatogram? cm and the solvent front is 10 cm on b. Paper chromatography can be used to identify each pigment in plant extracts by its characteristic solvent-matrix system which is a constant for a given pigment in a particular c. W hat are the three products of the reaction that occurs in plants the presence of Co2, light and chlorophyll?- and , d. Name two accessory pigments that play a role in photosynthesis in addition to (yellow-orange) and chlorophyll a and b: (yellow) Different pigments move at different rates in paper chromatography because of their differential e. in the and their characteristic tendency to be adsorbed on the cellulose fibers of the paper. Fill in the blanks a. b. In plant cells, the mechanism of cytokinesis includes formation of a partition called a 2. The mechanism of cytokinesis in animals: perpendicular to the axis of the spindle apparatus c. Name 4 stages of mitosis in sequential order as they occur; , and d. Region in the cell where metaphase stage chromosomes line up: 3. Name the stages of mitosis in the following figures Vhat is the difference between anaphase I and anaphase II of MIEOSIS?Explanation / Answer
1. (a) RF value = distance traveled by solute ( dye or pigment)/ distance traveled by solvent.
Therefore, RF value = 5cm / 10cm = 0.5 cm.
(b) Paper chromatography can be used to identify each pigment in plant extracts by its characteristic Rf value which is a constant for a given pigment in a particular solvent-matrix system.
(c) The three products of photosynthesis are Glucose, oxygen and water.
(d) The two accessory pigments that play role in photisynphotos are Carotenoids and Xanthophylls.
(e) Different pigments move at different rates in paper chromatography because of their differential solubility in the solvent .
2. b). The partition is called cell plate which is perpendicular to the axis of spindle apparatus.
c) The four stages of mitosis are prophase, metaphase, anaphase and telophase/ cytokinesis.
d) region of cell where metaphase chromosomes lineup is called Equator of spindle.
4. In Anaphase1 of meiosis homologous chromosomes separate to each side of the cell but centromere remains intact whereas in Anaphase2 sister chromatids separate and the centromere splits into two and leads to two separate chromatids.
6. The enzyme can be both an RNA molecule or a protein. Enzyme is not used or destroyed in the reaction .
Hence option (d) is correct.
7. For branching of amylopectin and glycogen alpha 1,6 linkage is used.
Hence option ( c) is correct.
8. Chromosome composition of 45, X0 is called turner's syndrome and is present in females without any bar body.
Hence option (d) is correct.
