Show Answer
Answer:
Correct Answer: C
Solution:
Option A) Funaria: This is not correct. Funaria is a moss in which the reproductive structures are surrounded by a layer of sterile vegetative cells.
Option B) Riccia: This is also not correct. Riccia is a liverwort, and like mosses, its reproductive structures are also surrounded by a layer of sterile vegetative cells.
Option C) Saccharomyces: This is the correct answer. Saccharomyces is a genus of fungi, not a plant. Fungi do not have a layer of sterile vegetative cells surrounding the egg. Instead, they reproduce by spores.
Option D) Cycas: This is not correct. Cycas is a type of gymnosperm, and like other seed plants, its reproductive structures are surrounded by a layer of sterile vegetative cells.
Therefore, the correct answer is C) Saccharomyces, as it is the only option that lacks a layer of sterile vegetative cells surrounding the egg.
