ANAKED seeds — ovules not enclosed by an ovary wall, exposed before and after fertilisation
BOnly unicellular bodies
CCell walls without cellulose
DFlowers and fruits
Answer & Solution
Correct answer: A. NAKED seeds — ovules not enclosed by an ovary wall, exposed before and after fertilisation
Greek 'gymnos' = naked, 'sperma' = seeds. Gymnosperms produce naked seeds because ovules are not enclosed in an ovary wall. They include Cycas, Pinus, Ginkgo, Sequoia (giant redwood).
