Which characteristic distinguishes gymnosperms from pterophytes?
A
Pterophytes produce cones, while gymnosperms do not.
B
Gymnosperms require water for fertilization, while pterophytes do not.
C
Pterophytes have flowers, while gymnosperms do not.
D
Gymnosperms produce seeds, while pterophytes do not.
Verified step by step guidance1
Understand the key difference between gymnosperms and pterophytes: Gymnosperms are seed-producing plants, while pterophytes (ferns) reproduce via spores and do not produce seeds.
Recall that gymnosperms include plants like conifers, which produce seeds in cones, whereas pterophytes rely on water for fertilization and produce spores instead of seeds.
Eliminate the incorrect options by analyzing the characteristics: Pterophytes do not produce cones, gymnosperms do not require water for fertilization, and pterophytes do not have flowers.
Focus on the correct characteristic: Gymnosperms produce seeds, which is a major evolutionary advancement compared to pterophytes that reproduce via spores.
Conclude that the distinguishing feature between gymnosperms and pterophytes is the presence of seeds in gymnosperms, while pterophytes reproduce using spores.
