The life cycle of Ectocarpus, Polysiphonia and kelps is:
1.Diplontic
2.Haplontic
3.Aplantic
4.Haplo-diplontic

Bryophytes are attached to the substratum by rhizoids that are:

Evolutionarily, the first terrestrial plants to possess vascular tissues are:

All the following are characteristics of bryophytes except:
1. spore producing
2. dominant gametophyte
3. lignified tissues
4. producing antheridium and archegonium

Which of the following Greek root word means "naked" and hence gives name to plants like cycas and pines?

The term ‘strobilus’ in a gymnosperm defines a:
1. collection of megasporophylls
2. collection of microsporophylls
3. site of sporangial development
4. collection of megasporophylls, microsporophylls and/or a site of sporangial development

Female sex organs of gymnosperms are called:

The bryophytes are also called as the amphibians of plants kingdom mainly because:
1. they respire through the moist epidermis
2. they depend on water for sexual reproduction
3. they require more water than most plants
4. they lack true roots

Vegetative reproduction in mosses is by:
1. Fragmentation and budding in secondary protonema
2. Only budding in secondary protonema
3. Adventitious roots and budding in secondary protonema
4. Fragmentation and budding in sporophyte

Unlike bryophytes and pteridophytes, in gymnosperms:
1. the male and female gametophytes do not have an independent existence
2. the vascular tissue is poorly developed
3. the reproduction is dependent on water in most cases
4. the plants bodies are clearly differentiated into root, stem and leaves
