Question

Some plants are difficult to chew.why?

Answer 1

Answer:

To keep small predators at bay, many plants have a mat of fine hairs on the surface of their leaves. To deter larger animals some plants have sharp spines or thorns, while others have leaves that sting or are bitter to taste. Cacti spines can be up to 6in (15cm) long.

The plants who protect themselves from getting eaten are difficult to chew.
