Describe the basic function of each of the three leaf tissues
Answer:

Answer: essay part
Explanation: I couldn't list eight products but here is my essay on a wool scarf. may not be the best but here:
_________________________
I chose a wool scarf.
wool is made mainly from the coat of a sheep, however, in other cases they can come from a alpacas, goats, and rabbits.
Sheep that have been domesticated and kept as livestock are frequently seen roaming around farms and other green areas. However, you can find wild sheep throughout North America, Central Europe, and the Middle East. Anywhere from mountains, deserts, or a sizable area can be home to sheep, depending on the species.
Sheep are naturally adapted to upland environments and harsh weather, which enables them to flourish where other mammals might find it difficult to survive. In the Middle East, Asia, Central Europe, and North America, where they live in steep hilly terrain, wild sheep are most frequently encountered.
Sheep are extremely reliant on their owners; they rely on them for food, protection, and health maintenance. Additionally, sheep rely on one another for safety
Wild sheep are susceptible to habitat destruction, poaching, and trophy hunting. Sheep can be found at research facilities and medical colleges where they are exploited for brutal tests. Sheep farmed for their wool, meat, and milk sometimes live in subpar conditions and lambs may even have their tails painfully "docked."
