I want to know the answer to the following question:
What is the number of plants in the Central Sahara?
All the background I'm provided with is that "Plants such as acacia trees, palms, succulents, spiny shrubs, and grasses have adapted to the arid conditions, by growing lower to avoid water loss by strong winds, by storing water in their thick stems to use it in dry periods, by having long roots that travel horizontally to reach the maximum area of water and to find any surface moisture and by having small thick leaves or needles to prevent water loss by evapo-transpiration.". Is that enough to answer the question?
Answer: no
