SECTION B QUESTION 2 Reаd the infоrmаtiоn belоw аnd answer the questions that follow: (The pictures labelled B and C on the Resources Addendum should be used for this question.) Paragraphs Cycads are classified as Gymnosperms and were the first plants to develop seeds. They existed on earth at least 225 million years ago. They have survived three mass extinction events. Cycads flourished during the time of the dinosaurs but declined at the same time that dinosaurs died out about 65 million years ago. Modern cycads evolved around 10 million years ago. 1 Cycads grow slowly, taking 10 to 20 years to reach maturity, and they reproduce infrequently. Each cycad plant is either male or female (dioecious), unlike most plants which are hermaphroditic. Their pollination depends on insect pollinators, in some cases involving only one specialized insect species. 2 Globally, there are 308 cycad species. South Africa is one of the world’s centres of cycad diversity with 38 species, 29 of which are endemic. 3 Having survived for so long, cycads are now threatened with extinction. Due to their beauty, many cycad species are highly sought after for horticulture and are considered collectors’ items. Some cycad species are harvested for traditional medicine markets. 4 The IUCN’s recent global assessment of cycads shows that 62% of the world’s cycad species are threatened, up from just over half less than a decade ago, making cycads the most threatened plant group globally. The Red List of South African Plants shows that 68% of South Africa’s cycad species are threatened, with nearly a third classified as Critically Endangered, making cycads the most threatened plant group in South Africa. 5 South African cycads are currently fully protected by national legislation. They are listed as threatened species in terms of the Biodiversity Act, and all activities with wild specimens (including possession and trade) are prohibited. However, it can be difficult to distinguish between a cycad plant that has been cultivated legitimately in a nursery and one that has been removed from the wild. Systems to implement and enforce legislation relating to cycads are weak, and the challenges are complex. 6 Adapted from National Geographic Vol 7, 2021
