Question

What are the plant's exterior defensive tissues?

• A. Cortex and epidermis
• B. Epidermis and cork
• C. Cortex and pericycle
• D. Cortex and cork

Answer 1

Answer:

B. Epidermis and cork

• The epidermis serves as the plant's protective layer in the primary stage.

• It forms the outer covering, but as secondary growth progress and the tree's girth increases, the outer cortical and epidermis begin to break down, and another meristematic tissue called cork cambium or phellogen develops the inner side.

• Phelloderm grows on the outside, forming periderm.
