- Oogamous of reproduction is seen in (i) Fucus (ii) Anabaena . . . - Toppr
Fucus and Volvox undergo oogamous form of sexual reproduction where a non-motile large egg cell called the oogonium is fertilized by a motile small sized male gamete
- Which of the following statements is true?Thin-walled non-motile spores . . .
Which of the following statements is true? Thin-walled non-motile spores are called zoospores A motile asexual spore produced by some algae, bacteria and fungi are Akinetes Uninucleate, non-motile, asexual spores produced by fungus are called conidia Thick-walled vegetative cells produced by algae during adverse conditions are called aplanospores
- Assertion :Algae show only anisogamous of reproduction. Reason: In . . .
Such reproduction is called isogamous Fusion of two gametes dissimilar in size, as in some species of Chlamydomonas is termed as anisogamous Fusion between one large, non-motiie (static) female gamete and a smaller, motile male gamete is termed oogamous So, the correct answer is 'Both Assertion and Reason are incorrect' Was this answer helpful?
- Aplanospores are uninucleate while zoospores are binucleate.
Aplanospores are nonmotile asexual spores found in certain algae and fungi They are formed from a part of a protoplast of a vegetative cell Zoospores are flagellated (motile) asexual spores
- Motile, asexual and endogenous spores produced in algal members are . . .
A Zoospores – flagellated, motile spores B Aplanospoers – Non flagellated,motile spores C Conidia – spores formed exogenously on the conidiophores D Cyst – a thick walled reproductive structure formed during unfavourable conditions So, the correct option is ‘zoospores’
- All statements are true about ferns exceptThe gametophyte is larger . . .
All statements are true about ferns except The gametophyte is larger than the sporophyte The sori give rise to the gametophytes Eggs are fertilized by sperm in the archeogonia Ferns possess vascular tissue for the transport of water and minerals Male gametes depend on water for fertilization
- Choose the correct statement :Members of phycomycetes are . . . - Toppr
Choose the correct statement : Members of phycomycetes are facultative parasites on plants Fusion of protoplasms between two motile or non-motile gametes is called plasmogamy Kingdom plantae includes all eukaryotic chlorophyll containing organisms and non-chlorophyllous oraganisms called plant Trichoderma belongs to basidiomycetes Euglenoids include diatoms
- The male gamete in Spirogyra is - Toppr
Non-motile and flagellate Solution Verified by Toppr Correct option is A Motile but aflagellate
