A scientist discovers a new species with the following characteristics: eukaryotic, multicellular, photosynthetic, lacks vascular tissue, exhibits alternation of generations with a dominant gametophyte. This organism MOST likely belongs to which plant group?
Pteridophyta
Bryophyta
Gymnosperms
Angiosperms
Which of the following is a defining characteristic of the plant kingdom?

Increases the number of spores produced
Allows for asexual reproduction
Simplifies the gametophyte generation

Chlorophyll a
Fucoxanthin
Phycoerythrin
Phycocyanin
Which algal group is characterized by the presence of mannitol as the reserve food material?
Chlorophyceae
Rhodophyceae
Phaeophyceae
Cyanophyceae
Which group of algae is responsible for the phenomenon known as 'red tides'?
Diatoms
Dinoflagellates
Euglenoids
Green algae
The cell wall of diatoms is impregnated with:
Calcium carbonate
Silica
Cellulose
Chitin
Which of the following is NOT a characteristic feature of the Pteridophytes?
Presence of vascular tissues
Sporophyte as the dominant phase
Seeds enclosed in fruits
Independent gametophyte
Which of the following is NOT a characteristic of Pteridophytes?
Possess true roots, stems, and leaves
Reproduce by spores
Non-vascular plants
Exhibit alternation of generations
