Question

1. until the 1950s, plants and fungi were generally classified together in kingdom plantae. now, they are classified in separate kingdoms. which of the following is a characteristic they share? a. both are autotrophic. b. both have a cell wall made of cellulose. c. both are heterotrophic. d. both are eukaryotic.

Explanation:

• Option A: Plants are autotrophic (make their own food via photosynthesis), but most fungi are heterotrophic (absorb nutrients from other organisms), so this is incorrect.
• Option B: Plant cell walls are made of cellulose, while fungal cell walls are made of chitin, so this is incorrect.
• Option C: Fungi are heterotrophic, but plants are autotrophic, so this is incorrect.
• Option D: Both plants and fungi are eukaryotic, meaning their cells have a nucleus and other membrane-bound organelles, which is a shared characteristic.

Answer:

D. Both are eukaryotic.
