ChL 26    Plant tissue:  Our Focus is on angiosperms. Life Cycle - germination --> seed formation -> death Annuals - life cycle is 1 single season. These are usually non-woody  (herbaceous) plants. Biennials - live for two connective seasons; Flowers & seeds m fee 2s* season; then plants die, Ex: carrots Roots (Fig.26.2) Shoots are the above-ground parts, such as leaves, stems, and flowers,  Roots anchor the plant. Root stores food (glucose) and supplies the shoots, 3 tissue systems ground Vascular (2 kinds) Dermal (covers and protects) Meristems Meristems are where growth starts. Apical Meristems  - the tip of the shoot; plant begins to lengthen and  root starts; primary growth.  Lateral Meristems  - Vascular cambium makes the secondary vascular tissue. Thick stem grows outward.  (3)1 o meristems protoderm = epidermis Ground = ground tissue Procambium = 1 vascular tissue Sturdier covering (periderm) that replaces the epidermis. As a whole, the thick stems and roots = 2 o growth. Plant tissues - Parenchyma – soft moist 1 growth of roots stem, leaves, flowers, and fruits. (living cells) - functions in storage and secretion. -
