Document Summary
There won"t be new material in the discussion. Chloroplast: a plastid that contains chlorophyll and in which photosynthesis takes place. cell wall: a rigid layer of polysaccharides lying outside the plasma membrane of the cells of plants, fungi, and bacteria. Isolating materials that might be harmful or a threat to the cell. It is the dominant form in bryophytes. sporophyte: (in the life cycle of plants with alternating generations) the asexual and usually diploid phase, producing spores from which the gametophyte arises. Explain alternation of generations in plants including ploidy. Characteristics of green plants: chloroplasts containing chlorophyll (harvests light to fix carbon, cell wall (plants have this because it allows cells to develop turgor pressure, which is the pressure of the cell contents against the cell wall. With water turgor pressure keeps a plant from wilting. Plant cells are usually square. : store starch (plants convert sources of energy from their environment in to a long lasting fuel: starch.
