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:

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
