Document Summary
Describe four shared characteristics and four distinct characteristics between charophytes and land plants. Similarities: rings of cellulose (synthesizing proteins), structure of flagellated sperm, formation of phragmoplast, both have peroxisome enzymes, Bryophytes- collective name for 3 phyla of small herbaceous plants (seedless nonvascular plants) Explain why most bryophytes grow close to the ground and are restricted to periodically moist environments. They are nonvascular plants and have flagellated sperm: describe three traits that characterize modern vascular plants and explain how these traits have contributed to success on land. Vascular tissues xylem and phloem to absorb water and nutrients respectively. Roots (absorb water from soil) and leaves (increase surface area for photosynthesis) to grow taller. Vascular tissues, xylem, phloem, sporophyte dominant, well developed roots and leaves. Distinguish between the following pairs of terms: microphyll and megaphyll; homosporous and heterosporous. Megaphylls: leaves with a highly branched vascular system. Homosporous: male and female on a single plant.
