Question

Root halrs vasuy Increase the siface area of contact between rool and dissolved minerals into the apoplast and symplast of the root Part B Which of these statements about the Casparian strip is true? Select all that apply. It is hydrophobic. lt prevents symplastic transport into the vascular cylinder. It blocks apoplastic transport into the vascular cylinder. It is selectively permeable to water It is a waxy band of suberin around cells of the endodermis. Submit Part C Drag the terms on the left to the appropriate blanks on the right to complete t

Explanation / Answer

Answer

1. Casparian strips is hydrophobic - waxy waterproof band

2. It blocks apoplast transport into vascular bundles - allows only minerals in the symplast to pass into the vascular cylinder through the plasma membrane of endodermal cells.
3. It is waxy band of submerin around cells of endodermis.

1. Apoplastic - cellwall water and dissolved minerals move
2. Symplastic - Cytoplasm molecules move
3. Symplastic - Require plasmodesmata
4.Apoplastic - Casparian strips block apoplastic pathway
