What You Need to Know You need to know how the structures of plant tissues and organs are directly related to their roles in

physiological processes. Plant organs are limited to roots, stems, leaves, flowers, fruit and cones. Physiological processes are limited to photosynthesis, cellular respiration, transpiration, and

reproduction. Plant tissues are limited to meristematic, ground, dermal and vascular tissues. Plant structures are limited to cambium, guard cells, phloem, seed, stomata and xylem.
