What is a key characteristic used to identify agricultural plants?

• The price of the plant

• The morphological characteristics

• The plant's popularity

What are the components of plant roots responsible for?

• Changing the color of the plant

• Performing photosynthesis

• Providing structural support and absorption

• Producing seeds

Answer explanation

Plant roots are responsible for providing structural support and absorption, aiding in the plant's stability and nutrient uptake.

What is the function of plant stems?

• To absorb nutrients from the soil

• To produce fruits only

• To support the plant and transport nutrients and water

• To attract insects for pollination

Answer explanation

Plant stems support the plant by providing structure and transport water and nutrients throughout the plant.

What is the primary function of leaves in plants?

• To provide structural support to the plant

• To capture light energy and allow for the exchange of gases

• To store nutrients for the plant

• To transport water from the roots to other parts of the plant

Answer explanation
