write the differences between algae and fungi in terms of habitat, type of nutrition, structure and reproduction.
Answers
Explanation:
Sl. No. Algae Fungi
1 Example: Oscillatoria (BGA), Oedogonium, Chara, Diatoms, Sargassum, Polysiphonia Examples: Pythium, Phytopthora, Rhizopus, Aspergillus, Puccinia, Agaricus (mushrooms)
2 Mostly aquatic Mostly terrestrial
3 Chlorophyll present Chlorophyll absent
4 Autotrophic nutrition Heterotropic nutrition
5 Light is necessary for the survival Light is not necessary for the survival
6 Few algae are prokaryotic (Blue Green Algae) Majority are eukaryotic All fungi are eukaryotic
7 Usually Green coloured Usually colourless (hyaline) sometimes bright coloured, never will be green
8 Plant body filamentous or parenchymatous Plant body filamentous or pseudo-parenchymatous
9 Cell wall composed of cellulose Cell wall composed of chitin
10 Cells usually uninucleate Cells usually bi-nucleate or multinucleate
11 Reserve food material is starch Reserve food material is glycogen
12 Spore are always endospores in algae (endospore = spores produced inside the sporangium) Spore are always endospores in algae (endospore = spores produced inside the sporangium)
13 Shows progressive complexity in sexual reproduction Shows progressive simplicity in sexual reproduction
14 Sexual reproduction is simple in lower forms of algae and it is complex in advanced forms Sexual reproduction is complex in lower forms of fungi and it is simple in advanced forms
15 Mitosis is usual type, nuclear membrane disorganize during mitosis Mitosis is special type called endo mitosis, nuclear membrane do not disorganize during mitosis
16 Parasitic members are very uncommon Parasitic members of very common
17 Zoospores, aplanospores, Chlamydospores etc. are important spores Conidiospores, zoospores and aplanospores are important spores
18 Sexual reproduction occurs by isogamy, anisogamy or oogamy Sexual reproduction occurs by isogamy, anisogamy, oogamy, gametangial contact, gametangial copulation, spermatization and somatic hybridization
19 During union of games, plasmogamy immediately follows karyogamy In higher fungi delayed karyogamy occurs
20 Dikaryotic phase is completely absent Distinct dikaryotic phase is present in some higher fungi like members of Ascomycetes and Basidiomycetes
21 Clamp connection and crozier formation are completely absent in algae Clamp connection and crozier formation are present in higher fungi for the establishment of dikaryotic phase
22 Para-sexual cycle is not reported in algae Para-sexual cycle is reported in many fungi
