Biology : Plant Kingdom

Differentiate between the following:
homosporous and heterosporous pteridophyte

Differentiate between the following:
syngamy and triple fusion

How would you distinguish monocots from dicots? 

Describe the important characteristics of gymnosperms. 

Cyanobacteria are classified under

• Protista

• Plantae

• Monera

• Algae

Fusion of two gametes which are dissimilar in size is termed as

• Oogamy

• Isogamy

• Anisogamy

• Zoogamy

Holdfast, stipe and frond are found in 

• Rhodophyceae

• Chlorophyceae

• Phaeophyceae

• All of the above

A plant shows thallus level of organization. It shows rhizoids and is haploid. It needs water to complete its life cycle because the male gametes are motile. Identify the group to which it belongs to

• Pteridophytes

• Gymnosperms

• Monocots

• Bryophytes

Plants of this group are diploid and well adapted to extreme conditions. They grow bearing sporophylls in compact structures called cones. The group in reference is

• Monocots

• Dicots

• Pteridophytes

• Gymnosperms
