• They contain vascular tissue.

• They were among the first plants to grow on land.

• They produce seeds.

Which structures help bryophytes anchor to surfaces and absorb water and nutrients?

• Roots and leaves

• Stems and flowers

• Rhizoids and phyllids

• Spores and seeds

What significant role do mosses play in the environment?

• They produce large, edible fruits.

• They store large amounts of carbon.

• They grow into tall trees that provide shade.

• They attract a wide variety of pollinators.

How do hornworts benefit from their symbiotic relationship with bacteria?

• The bacteria provide water to the hornworts.

• The bacteria provide housing for the hornworts.

• The bacteria provide nitrogen for the hornworts.

• The bacteria provide sunlight for the hornworts.
