Roots will always have primary roots and branch roots (secondary roots), and a root apical meristem (tip of root) (ram) Ma(cid:374)(cid:455) ti(cid:373)es also ha(cid:448)e : petioles- stem like thing leading to leaf, stipules- two very little things where a leaf branches off. There are 3 plant organs: root parts, primary root, branch roots, ram, leaf parts (shoots, blade, petiole, stipules, stem parts (shoots, nodes. Leaf venation is how to distinguish dicot and monocots. Stem will have nodes and internodes at regular intervals. Nodes indicated by presence of leaves, or leaf scars, which sometimes encircle entire stem. What part do you eat of these vegetables. As long as the stem and sam are alive plants will grow and only the leaves will die. Magnifications of objective lenses on the scopes: 4x, 10x, 20x, 40x. Magnification of the eye pieces: 10x. Do not use coarse focus at 20x or 40x only the fine focus. Easy to damage the lens and the slide.
