Consider the following statements with reference to the Cycad Plants:1...
Oldest surviving plant species
- Cycad plants are considered to be the oldest surviving plant species on Earth.
- They have been around for over 280 million years, dating back to the time of dinosaurs.
- These plants have survived major environmental changes and have adapted to various conditions over the years.
Gymnosperms and cone reproduction
- Cycad plants are gymnosperms, which means they produce seeds that are not enclosed within an ovary or fruit.
- They reproduce using cones, similar to other gymnosperms like conifers.
- The male cones produce pollen, which is then transferred to the female cones for fertilization.
- This method of reproduction is characteristic of gymnosperms and distinguishes them from angiosperms, which have enclosed seeds within fruits.
Therefore, both statements given in the question are correct. Cycad plants are indeed the oldest surviving plant species on Earth, and they are gymnosperms that reproduce using cones.

Consider the following statements with reference to the Cycad Plants:1...
Scientists are using remote sensing technologies and artificial intelligence to assist the search for a female to Encephalartos woodii plant in the Ngoye Forest.
- It is a plant from South Africa and is a member of the cycad family with thick trunks and large stiff leaves that form a majestic crown.
- Cycads are the oldest surviving plant groups alive today and are often referred to as “living fossils” or “dinosaur plants” due to their evolutionary history dating back to the Carboniferous period, approximately 300 million years ago.
- During the Mesozoic era (250-66 million years ago), also known as the Age of Cycads, these plants were ubiquitous, thriving in the warm, humid climates that characterised the period.
- Although they resemble ferns or palms, cycads are not related to either. Cycads are gymnosperms, a group that includes conifers and ginkgos. Unlike flowering plants (angiosperms), cycads reproduce using cones.
- It is impossible to tell male and female apart until they mature and produce their magnificent cones.
- Female cones are typically wide and round, and male cones appear elongated and narrower.
- The male cones produce pollen, which is carried by insects (weevils) to the female cones. This ancient method of reproduction has remained largely unchanged for millions of years.
- Despite their longevity, today cycads are ranked as the most endangered living organisms on Earth with the majority of the species considered threatened with extinction.
- This is because of their slow growth and reproductive cycles, typically taking ten to 20 years to mature, and habitat loss due to deforestation, grazing and over-collection.
- Threats: Their striking appearance and ancient lineage make them popular in exotic ornamental horticulture and that has led to illegal trade.
Hence both statements are correct.
