Land Plants Complex multicellular organism that range in size from minute to MASSIVE. Adaptations of this type of plant include anatomical, physiological, and reproductive features. Waxy Cuticle Covers aerial portions of a plant, protects against water loss. Resides ON TOP of the epidermis. Stomata Used for gas exchanged, required for photosynthesis. Guard Cells surround this and can open or close it depending on environmental/chemical interactions. Antheridia Gametangia that produce SPER...

Green plant phylogeny ANSWER: - green algae and land plants share a common ancestor - all green plants are photo autotrophic but not all photo autotrophic plants are green 2 major groups of green algae ANSWER: - chlorophytes: never made it to land - charophytes: sister group to all land pants - ancestral charophytes species gave rise to land plants - streptophytes have charophytes and land plants - land plants have multicellular haploid and diploid stages and diploid embryos(not foun...
