What thing helped early land plants get nutrients from rocks (I literally cannot understand what this question was)

What thing helped early land plants get nutrients from rocks (I literally cannot understand what this question was)

Fungi

The sperm of these organisms do not swim through water

Gymnosperms

What is the term for the waxy layer on plants

Cuticle

In vascular plants what is the dominant generation

sporophyte

What are some advantages of seeds for the offspring

They are reproductive structures that provide nourishment, protection, and dispersal and do not attract pollinators

What phylum contains the most successful gymnosperms

Coniferphyta

In the phylum Sphenophyta; these have joint vertical stems and whirls of scalelike leaves

Horsetails

What are fiddleheads characteristics of

Ferns

What's the primary function of fruit

Provides protection to the seed and allows seeds to be dispersed

What does the xylem transport

Water and minerals from the roots to the leaves

What is sphagnum moss often used for

Retaining water and enriching the soil

What is missing in nonvascular plants

Xylem and Phloem, vascular tissue, true roots, stems, and leaves

What's the definition of a seed

A plant embryo inside a protective coat

What are the ecological role of mosses

They can grow in areas where fires destroyed plants, prevent soil erosion, accumulates inorganic and organic matter

Explain what a bryophyte is

Nonvascular plants that grow in moist areas

Three characteristics of vascular plants

Vascular tissue, true roots, stems and leaves, xylem and phloem, alteration of generations

True roots, stems, and leaves are characteristics of all seed plants

True

Which of the following phylum of plants produces seeds

Coniferphyta

If a plant has a flower what is it

angiosperm

What are some functions of spores and seeds

Disperse, and provide protection

How is green algae different from plants

Green algae requires water and it does not have cuticles, algae does not have structural support or stems

Why do nonvascular plants have to live in moist areas

Reproduction and they don't have roots or stems to take in or transport water

Name 3 bryophytes

Moss, liverwort, hornwort

Characteristics of bryophytes

Needs to live in moist areas, don't have true roots, leaves, or stems

Which plant phylum contains the tallest and most massive plant

Coniferphyta

Are conifers seedless or seed plants

seed

How come conifers can live in high elevations with cold surface areas

The needles don't fall off and have a smaller surface area that can be harmed
