Definition
| Consists of a node w its attached leaf, the internode below the leaf, and the bud at the base of the internode. Repeated units under apical meristem. |

| lies at the junction of the stem and the petiole of the plant. |
|
|
Term
|
Definition
| interfasicular regions are wide, hence the procambial strands and vascular bundles form a system of discrete strands around the pith. |

| What are the functions of stems? |
|
Definition
| Support/conduction puts leaves closer to light. Transport nutrients down to roots up- water/minerals. |
|
|
Term
| What are the function of tubers? |
|
Definition
| store nutrients, roots underneath stems on top. |

Term
| What are the functions of rhizomes? |
|
Definition
| vegetative reproduction, food storage. |
|
|
Term
| Compare and contrast the activities of the SHOOT apical meristem and the root apical meristem. |
|
Definition
| rise to stem and leaves, most embryogenisis in flowers, leaf primordial. Stem cells, daughter cells, organization center, founder cells. |
|
|
Term
| Compare and contract the activities of the shoot apical meristem and the ROOT apical meristem. |
|
Definition
| Rise to roots, cells in to different directions, division, elongation, maturation, rootcap. 2 dimensional cell production, infrequent cell division. |
|
|
Term
| Compare and contrast the activities of the SHOOT apical meristem and the ROOT apical meristem. |
|
Definition
| Protoderm, procambium, ground-epidermis, PVT, ground tissue. |
|
|
Term
| Compare and contrast the structures of the SHOOT apical meristem and the roost apical meristem. |
|
Definition
| young leaf node, procambium all around.Protoderm going up (not down like in roots), ground meristem (roots). |
|
|
Term
| Compare and contrast the structures of the shoot apical meristem and the ROOT apical meristem. |
|
Definition
| Root cap, root hair. Procambium in center. 3 different zones,(diff, elong, division), quistent center. Protoderm going downward. |
|
|
Term
| Compare primary xylem maturation in STEMS to primary xylem maturation in roots. |
|
Definition
| Endoderm leads to protoderm, ground meristem, 3 discrte procambial stems, one mature tracheary element (inward next to pith). Xylem eventually differentiates in other direction. Primary xylem is stretched during elongation of internode and frequently destroyed. |
|
|
Term
| Compare primary xylem maturation in stems to primary xylem maturation in ROOTS. |
|
Definition
| Vascular cylinder in center one soild cylinder. Some have piths vascular tissues arise from procambium. Center of vascular cylinder is primary xylem, procambial cells between metaxylem differentiates after protoxylem which occupies the center of the vascular cylinder. |
