Question

question 13 (2.5 points)
a pine tree is a
flowering plant
seedless plant
sporophyte
bryophyte
gametophyte
question 14 (2.5 points)
fungal cell walls consist primarily of
cellulose
lignin

Explanation:

• Question 13: Pine trees are gymnosperms. In the plant life cycle, the dominant stage for gymnosperms (and most plants) is the sporophyte stage. Flowering plants are angiosperms (different from gymnosperms). Seedless plants (like ferns in some cases) reproduce via spores in a more prominent way than seed - bearing plants. Bryophytes (mosses) have a dominant gametophyte stage, and gametophytes are the haploid, sexual stage of the plant life cycle (not dominant in pine trees).
• Question 14: Fungal cell walls are made of chitin. But among the given options:
• Cellulose is the main component of plant cell walls.
• Lignin is a complex polymer that provides structural support in plant cell walls (especially in woody plants).

Answer:

Question 13: sporophyte
Question 14: (Since the correct answer 'chitin' is not there, but if we assume it's a mis - optioning and based on elimination from the given options, there is an error. But if we consider the knowledge that it's not cellulose (plant cell wall) or lignin (plant structural polymer), but if forced to choose from the given wrong - option set, there is no correct answer. However, if we assume it's a typo and the intended answer is based on knowledge: fungal cell walls - chitin (not in options), plant cell walls - cellulose, plant structural (woody) - lignin)
