Document Summary
Lecture 1: plant tissue system + cells and meristem organization. Vascular plants: diversity from common building blocks. Stems and roots = indeterminate growth: modular, reiterative development (repeating same theme over and over again to get structure, flowers +dicot leaves = determinate growth, organ system. Leaves: systems (root and shoot, gene expression and identity, anatomy. Aerenchyma = programmed cell death to make air pipes from root to shoot. Function = photosynthesis, storage, pith, local transport. Tbo stain = darker pink-purple: sclerenchyma. Thickened primary + secondary cell walls (lignified) Fibres, parenchyma cells, tracheids, vessel elements, transfer cells. Fibres, parenchyma cells, sclereids, sieve-tube members and companion cells or sieve cells and albuminous cells, transfer cells. Shoot and root epidermal cells, trichomes, cells associated with pores, guard cells and subsidiary cells. Fibres, parenchyma cells, sclereids, sieve-tube members and companion cells, sieve and albuminous cells. Cork cells, cork cambium, parenchyma cells: xylem and phloem differentiate from procambium/provascular tissue, xylem.
