Definition of symplasm in English:

symplasm

noun ˈsɪmplaz(ə)mˈsimˌplazəm

Botany

A symplast, especially the cytoplasm of which it is composed.
〔植〕合胞体，共质体
Example sentencesExamples
- Exchanges of solutes between apoplastic and symplastic compartments, including contamination by phloem sap or by the symplasm of wounded cells at the leaf section, probably accompany this ebb and flow of apoplastic water.
- As a general rule, the time of exposure to the labelled solution should be long enough to allow nutrients to pass the free space of the apoplasm and to reach the symplasm.
- Likewise, efflux from the root symplasm to the transpiration stream must cross the plasma membrane of cells within the stele of the root.
- Consequently, ions are taken up into the symplasm (shaded area) at the plasma membranes of the epidermis or cortex or the outer face of the endodermis.
- The barrier formed by the Casparian band suggests that to reach the stele, water has to enter the symplasm and cross the membranes of endodermal cells or other cell types that sit external to the endodermis.

Derivatives

symplasmic

adjective

Botany

Using the green fluorescent protein expressed specifically from companion cells of the phloem has provided good evidence that there is symplasmic continuity between the phloem of tobacco and the parasitic plant Cuscuta reflexa.
Example sentencesExamples
- Cuttler et al. reported that a reduction in average cell size, and hence in the relative symplasmic water per cell, may result in a decrease in tissue osmotic potential.
- To check the purity of the apoplasmic solution, the activity of malic dehydrogenase in the apoplasmic and symplasmic solutions was determined according to Bergmeyer and Bernt.
- Recent studies revealed that these zones and layers form separate symplasmic domains.
- High densities of plasmodesmata support symplasmic delivery of accumulated nutrients to underlying storage cells where polymer formation (starch, protein) takes place.
