2 Characteristics of Algae EukaryotesMost unicellular, but some multicellularAutotrophicProduce oxygen that is returned to the atmosphereRange in size from microscopic to hundreds of feet in lengthDo not have true roots, stems, nor leavesForm gametes (eggs & sperm)Found in freshwater, marine, and moist soil habitatsMost have flagella

22 BryophytesBryophytes are small, nonvascular plants.Bryophytes lack vascular tissue and have life cycles dominated by the gametophyte phase.Roots are absent in bryophytes, instead there are root-like structures known as rhizoids.
24 PteridophytesPteridophytes are vascular plants have specialized transporting cells xylem (for transporting water and mineral nutrients) and phloem (for transporting sugars from leaves to the rest of the plant).Pteridophytes are larger and more complex than bryophytes, and have a life cycle where the sporophyte is more prominent than the gametophyte.
29 Seed producing plants can be divided into two groups Gymnosperms - produce seeds but the seeds are not contained inside any structure. These plants have cones.Angiosperms - the seeds are produced inside and “ovary” which becomes the fruit. These plants have flowers.
