During the process of microsporogenesis in angiosperms, how many tetrads are formed, from a single microspore?
1 1
2 2
3 8
4 4
Explanation:
During the process of microsporogenesis in angiosperms a single microspore forms one tetrads. Young microspore mother cell is (polygonal and are tightly packed) get loosely scattered due to increase in size of pollen grains sac. Microspore mother cell is a diploid cell in plants that divide by meiosis to give rise to 4 haploid cells.

Which one group of organism possess minimum number of chromosome?
1 Brassica oleracea and Mucor hemolysis
2 Carica papaya and Haplopappous gracilis
3 Pisum sativum and Mucor hemolysis
4 Haplopappus gracilies and Mucor hemolysis
Explanation:
Haplopappus gracilis and Mucor hemolysis are angiospermic plant and a bread mould fungi respectively. These two organism possess minimum number of chromosome. In Mucor hemolysis $\mathrm{n}=2$ and in Haplopappus gracilies $2 \mathrm{n}=4$, Carica papaya and Pisum sativum contain 18 and 14 number of chromosomes respectively.

During the characteristic feature of angiosperm (double fertilization) one of the sperm fuses with egg cell and other sperm fuses with
1 Another egg cell to form $3 n$ tissue
2 Nuclear cell to form $2 \mathrm{n}$ tissue
3 Central cell to form triploid tissue
4 Two nuclei to form diploid tissue
Explanation:
In angiosperm fertilization is carried out by syngamy (fusion of egg cell with sperm or male nucleus) and another nucleus fuses with secondary nucleus (two polar nuclei or central cell) to form triploid tissue, endosperm. Thus, fertilization is completed in two steps, it is referred as double fertilization.

Which is correct regarding saprophytic angiosperm?
1 They secrete enzyme outside the body and absorbes the nutrients.
2 They have mycorrhiza with fungi
3 They takes food and then digested it
4 They are photosynthetic
Explanation:
Saprophytic organism break dead organic matters by secreting digestive enzymes and then absorb the nutrient molecules from dead organisms. They excrete hydrophytic enzyme into the external medium. These enzyme are cellulose, chitinase, amylase, proteinase etc. They hydrolyze different component for organic matter and then the simple and soluble substance are absorbed.
