Question

Which of the following would most likely function as a plant's ""first line of defense"" against an herbivore? Production of jasmonic acid Secondary metabolite that inhibits development Change in cell membrane potential Trichomes Canavanine

Answer 1

Production of a secondary metabolite.

Step-by-step explanation:

The plants are capable of protecting themselves from herbivores , which are their predators. This process is known as adaptation, because it will allow them to survive in the environment.

The production of the second metabolites have negative effects on the herbivores that eat them.

The metabolites produced affect the survival, behavior and growth of the herbivores when eaten. Because they are toxic and can reduce the digestion of plant in herbivores.

The secondary metabolites also make the plants repellent to the herbivores.

Note that, herbivores are plants that feed only on plants and plant products.

Answer 2

Trichomes

Step-by-step explanation:

Trichomes are specialized systems of epidermal origin that exist as extrusions or appendages on plant surfaces, but can be seen on lichens and even algae.

Trichomes are very distinct in structure and activities towards stress resistance, inclusive of extreme light or temperature, and insect and pathogen defence. They exhibit hair-like structures, and may be in the form of scales, buds or papillae and varies from very tiny unicellular to very large multicellular structures.
