Bed Of Thorns

 

Defence

 

 

Learn.genetics.utah :

Physical defenses are a first line of protection for many plants. These defenses make it difficult for herbivores to eat plants. Examples of physical defenses are thorns on roses and spikes on trees like hawthorn. These physical defenses hurt the herbivores and stop them from eating plants’ stems or leaves.
