Abscisic acid – a plant hormone that promotes leaf detachment, inhibits germination, and dormancy of seeds and buds. Stimulates the closing of stomata. Actin – forms cytoskeleton, regulates cell division, cell expansion, organelle movement, vesicle trafficking, etc Cellulose – polysaccharide made of glucose, main component of plant cell walls. Chlorophyta – phylum consisting of green algae. Endosperm – Tissue produced by seeds of flowering plants at time of fertilization. Surrounds embryo and provides nutrition with starch. Gametophyte – haploid, multicellular phase of plants and algae that undergo alternation of generations (one generation diploid, next haploid, next diploid, etc). Giberellins – plant hormones that stimulate stem elongation, germination, and flowering. Lignin – complex organic polymer in cell walls making them rigid and woody. Meristem – region of plant tissue consisting of actively dividing cells, found mostly in growing roots and shoots and the cambium. Pollen – fine powdery substance consisting of microscopic grains discharged by male part of a flowering plant. Each grain contains a male gamete that can fertilize an ovule. Transported by wind, insects, or other animals.
