In order to protect itself against fires, plants have thick (a)  

Many conifers produce resin, which is a (a)   substance

Resin helps protect plants because the sticky substance helps trap what?

• caterpillars

• butterflies and other pollinators

• many animals that try to eat the plant

Match the following with the correct answer

• bark

• In order to protect itself from insects biting it, plants use

• hairy leaves

• In order to protect itself against water loss, plants have

• resin

• In order to protect itself against fires, plants have thick

• prickles

• In order to protect itself against animals, plants use

During a school trip to a local park, Emma, Olivia, and Liam noticed a plant with a sweet-smelling flower. Can you guess why the plant has such a flower?
