BIOL 110 Study Guide - Final Guide: Cycad, Gymnosperm, Gnetophyta
Document Summary
Contain two forms of chlorophyll as photosynthetic pigments. Problems associated with the terrestrial environment: resource acquisition, desiccation, herbivory, requires structural, chemical, and physical adaptations. Root systems: surface area for uptake of nutrients and water, anchor plant in fixed position. Shoot system (leaves & stems: absorb sunlight and co , site of photosynthesis, transportation of water and nutrients, stomata control uptake of co . Microscopic pores that restrict water loss and: cuticle. Wax coating that helps conserve water: xylem dissolved ions. Tissue specialized for transport of water and: phloem other photosynthetic products. Tissue specialized for transport of sugars and: secondary metabolic products, wax ii. iii. iv. v. Development of pollen and seeds: pollen grain. Embryonic sporophyte with nutritive tissues and protective coat that develops from female gametophyte. Lack seeds and flowers: body structure i. ii. iii. Living groups of bryophytes: phylum bryophyta: mosses, phylum anthocerophyta: hornworts, phylum hepatophyta: liverworts.
