IMP OF PLANT KINGDOM
1) Isogamous sexual reproduction in algae- Ulothrix (flagellated)
Spirogyra (non-flagellated)
2) Anisogamous sexual reproduction in algae- Udorina
3) Oogamous sexual reproduction in algae- Volvox, Fucus
4) Algin- Brown Algae
5) Carragreen - Red Algae
6) Agar- Gelidium, Gracilaria
(Red algae)
7) Motile asexual spores in algae- Zoospores
8) Laminarin, Mannitol- stored food of Brown algae (complex carbohydrate)
9) Fucoxanthin- Brown Algae
10) Phycoerythrin- Red Algae
11) Floridean Starch Found in Red algae, similar to amylopectin and glycogen
12) The main plant body is a gametophyte- Bryophytes
13) Peat- Sphagnum
14) In liverworts - asexual reproduction by fragmentation or by gemmae (green, multicellular, asexual buds) formation
15) In mosses - asexual reproduction by fragmentation & budding in 2° protonema
16) Microphylls- Selaginella
17) Macrophylls- Fern
18) Heterosporous pteridophytes- Selaginella,
Salvinia, Azolla, Marsilea
19) Vascular plants without seeds- Pteridophytes
20) Aquatic ferns - Azolla, Salvinia, Marsilea
21) Mycorrhiza- Pinus
(symbiotic association with fungi in the roots)
22) Coralloid roots- Cycas
(nitrogen-fixing cyanobacteria in the roots)
23) The tallest gymnosperm- Sequoia (redwood tree)
24) Pinus - Winged shape pollen grain, Monoecious
25) Ginkgo - Living fossil
26) Microscopic angiosperm Wolffia
27) Parallel venation- mostly in Monocotyledons
28) Reticulate venation- Mostly in Dicotyledons
29) The cells of embryo sac are- Haploid
30) Algae showing haplo-diplontic life cycle- Ectocarpus, Polysiphonia, kelps
31) Diplontic life cycle - Fucus
32) Zygotic meiosis - Haplontic life cycle
33) Chlorella - Unicellular alga, protein rich
34) Porphyra, Laminaria and Sargassum - marine algae, used as food
35) Laminaria - Good source of Iodine
