Exploring Plant Structures and Adaptations

Why are plants considered essential for life?

• They are the main consumers in food webs.

• They consume all the oxygen.

• They produce carbon dioxide.

• They are the main support for food webs.

What are the two major categories of plants?

• Vascular and nonvascular

• Flowering and non-flowering

• Tall and short

• Green and non-green

What does the xylem transport in vascular plants?

• Sugars

• Carbon dioxide

• Nutrients

• Water

What is the primary function of phloem in plants?

• Transporting water

• Anchoring the plant

• Absorbing sunlight

• Transporting sugars

What are the three major reactants needed for photosynthesis?

• Water, light, and carbon dioxide

• Water, oxygen, and light

• Carbon dioxide, oxygen, and light

• Water, nitrogen, and light

What organelles in plant cells capture light energy for photosynthesis?

• Ribosomes

• Mitochondria

• Nuclei

• Chloroplasts

What is the role of stomata in plants?

• Transporting water

• Anchoring the plant

• Gas exchange

• Absorbing nutrients

Why do plants close their stomata at night?

• To capture insects

• To release oxygen

• To absorb more sunlight

• To conserve water

How do desert plants adapt to conserve water?

• By producing more oxygen

• By having broad leaves

• By opening stomata at night

• By growing taller

Why do carnivorous plants digest insects?

• To conserve water

• To absorb more sunlight

• To produce more oxygen

• To supplement their nitrogen needs
