  1. MCQ'S: Anatomy of Flowering plants By: Aprajita shankhdhar 75 46


  2. 1. Passage cells are thin - walled cells found in . (a) phloem elements that serve as entry points for substance for transport to other plant parts . (b) testa of seeds to enable emergence of growing embryonic axis during seed germination .(c) central region of style through which the pollen tube grows towards the ovary .(d) endodermis of roots facilitating rapid transport of water from cortex to pericycle.


  3. 2. .For a critical study of secondary growth in plants, which one of the following pairs is suitable? . (a) teak and pine (b) deodar and fern . (c) wheat and maiden hair fern .(d) sugarcane and sunflower.


  4. 3. . A common structural feature of vessel elements and sieve tube elements is . (a) enucleate condition . (b) thick secondary walls (c) pores on lateral walls .(d) presence of P-protein


  5. 4. . In a longitudinal section of a root, starting from the tip upward, the four zones occur in the following order: (a) root cap, cell division, cell enlargement, cel . (b) root cap, cell division, cell maturation, cell .(c) cell division, cell enlargement, cell maturation, root .(d) cell division, cell maturation, cell enlargement, root maturation enlargement cap cap


  6. 5. . Chlorenchyma is known to develop in the (a) cytoplasm of Chlorella . (b) mycelium of a green mould such as Aspergillus (c) spore capsule of a moss . (d) pollen tube of Pinus


  7. 6. The aleurone layer in maize grain is specially rich in (a) proteins (b) starch *(c) lipids (d) auxins


  8. .In which one of the following is nitrogen not a constituent? . (a) idioblast . (b) bacteriochlorophyll . (c) invertase (d) pepsin


  9. 1. .d): Endodermis is a single layered structure which separates cortex from stele. There are both thick walled and thin walled cells in the endodermis. The thin walled cells are known as passage cells or transfusion cells which are opposite the protoxylem groups. These cells help in rapid transport of water from cortex to pericycle


  10. 2. . (a): Secondary growth is observed in dicots and gymnosperm. It is not observed in pteridophytes and rarely observed in monocots. .Secondary growth results in increase in girth or diameter of the stem by formation of secondary tissue by the activity of lateral meristem. So for study of secondary growth, teak (angiosperm) and pine (gymnosperm) are best suited.


  11. 4. (a) root cap, cell division, cell enlargement, cell maturation


  12. 6 . In monocotyledons the seeds are generally endospermous. The internal structure of grain can be studied in a longitudinal section. It shows two distinct regions upper large region, the endosperm and lower smaller region, the embryo. The endosperm is surrounded by a special one cell thick layer, called aleurone layer It is filled with aleurone grains which are proteinaceous in nature. Other components of this layer are phytin, carbohydrates and small amounts of phospholipids are also present.
