|
dermal tissues |
a tissue, outer covering of the plants |
|
|
|
vascular tissue |
conduct water and food transport throughout the plant |
|
|
|
ground tissue |
carries out photosynthesis, for photosynthesis storage of products and support |
|
|
|
meristematic tissue/ meristem |
continuously dividing, undefferintiated, young, clumps of small cells with dense cytoplasm and large nuclei, responsible for the growth of the plant |
|
|
|
analogous |
similar function, different structure |
|
|
|
homologous |
same ancestor, with the same structure with different function |
|
|
|
classification of meristem |
according to origin, according to position, according to angle of cell division plate |
|
|
|
promeristem |
dividing cells located at the shoot and root tip to produce primary cells of meristem |
|
|
|
initials |
continous division, direct embryonic origin, restricted to plumule and radicle |
|
|
|
quiescent centre |
storage of genetic materials, non-dividing stage, totipotent |
|
|
|
differentiated |
plant cells generally cannot divide or produce cells of a different type |
|
|
|
undifferentiated |
can be produced into a specialized cells, cell that needs develop into a particular cell variant. |
|
|
|
totipotent |
cell that is capable of developing into any cell type. |
|
|
|
pluripotent |
cells have the potential to differentiate into specialized cells, These cells then can differentiate into a a more functional plant |
|
|
|
multipotent |
cells that can develop into more than one cell type, capacity to self-renew by dividing and to develop into multiple specialized cell types present in a specific tissue or organ, and more limited than pluripotent cells. |
|
|
|
cell potency |
cellular fate; totipotent, pluripotent and multipotent |
|
|
|
primary meristem/ histogens |
cells of the primary meristems have determined fate |
|
|
|
primary meristem/ histogens |
cells of the primary meristems have determined fate |
|
|
|
shoot and root tip |

|
|
dermatogen/ protoderm |
producing the epidermis, dermal tissue |
|
|
|
ground meristem |
giving rise to the ground tissue system, ground tissue |
|
|
|

|
|
cork cambium/ phellogen |

|
|
rhizodermis |
dermatogen in the root, root epidermis |
|
|
|
periblem |
primary cortex |
|
|
|
plerome |
central core region of the primary meristem, gives rise to the stele |
|
|
|
calyptrogen |
rapidly dividing cells in the root tip, that gives rise to the root cap |
produces calyptra |
|
|
calyptra |
formed by calyptrogen, with genetic information |
|
|
|
root tip |
abiotic, more sensitive shoot system against microbial infections |
|
|
|
2 shoot system |
shoot apex root apex |
|
|
|
secondary meristem |
product of the primary meristem, arise by the differentiation of primary tissue cells |
|
|
|
vascular cambium |
secondary thickening of the plant organs |
|
