Identify the gymnosperm whose pinnate leaves persist for years and which bears male and female cones on DIFFERENT trees.
AGinkgo — extinct except as cultivars
BSequoia
CPinus (monoecious — male + female cones on same tree)
DCycas — DIOECIOUS; male cones and megasporophylls on different trees; pinnate leaves persist for years
Answer & Solution
Correct answer: D. Cycas — DIOECIOUS; male cones and megasporophylls on different trees; pinnate leaves persist for years
In Cycas, male cones and megasporophylls are borne on DIFFERENT trees (dioecious); Pinus is monoecious (both cones on same tree). Cycas has pinnate compound leaves that persist for several years.
