Which of the following statements regarding fern is ture?
A) Ferns do not have lignfied cell wall
B) Ferns have well developed vascular tissue, roots, and stems
C) Ferns produce seeds
D) Ferns produce pollen
這題答案為B
我想問一下A選項,在演化的過程中,哪各階段才出現lignfied cell wall?
次級細胞壁才算lignfied cell wall,那bryophyte有次級細胞壁嗎?
謝謝大家囉~
