All the following differentiate gymnosperms from the higher cryptogams except:
(1) Presence of an independent green gametophyte
(2) development of an ovule
(3) Formation of the pollen tube
(4) Presence of cambium
Heterosporous ferns include both:
(1) Lycopodium and Equisetum
(2) Selaginella and Salvinia
(3) Psilotum and Phylloglossum
(4) Selaginella and Equisetum
The life cycle is not haplo-diplontic in:
(1) Bryophytes
(2) Pteridophytes
(3) Polysiphonia
(4) Fucus
The endomembrane system of a eukaryotic cell includes all except:
1. Vacuoles
2. Lysosomes
3. Peroxisomes
4. Golgi complex
Asexaul reproduction by pear shaped biflagellate zoospores is seen in most:
(1) Green algae
(2) Brown algae
(3) Red algae
(4) Both (2) and (3)
All the following pteriodophytes belong to the Class Pteropsida except:
(1) Dryopteris
(2) Pteris
(3) Selaginella
(4) Adiantum
Sexual reproduction by non-flagellated but similar in size gametes is seen in:
1. Chlamydomanas
2. Volvox
3. Spirogyra
4. Fuccus
In mosses, the sex organs are seen in:
1. Protonema stage
2. Leafy stage
3. Capsule of the sporophyte
4. Seta of the sporophyte
The features seen in the gymnosperm Cycas include:
I. Coralloid roots
II. Unbranched stems
III. Pinnate persistent leaves
IV. Male cones and megasporophyllys borne on same plant
1. I and II only
2. I and IV only
3. I, II and III only
4. I, II, III, and IV
Both bryophytes and pteridophytes:
(1) are vascular cryptogams
(2) have a dominant sporophyte
(3) reproduce only sexually
(4) are haplo-diplontic
