- A. Plant Transportation1. Transport of Substances from the epidermis towards the vascular tissuesFill-in the blanks with the following choices: casperian strip, symplast pathway, xylem, plasmodesmata, apoplast pathway Water and solutes either in solution or suspension move through cells through the apoplast and symplast pathway. __________ involves movement of substances through the intercellular spaces (matrix) between cells. __________on the other hand, allows movement of substances by passing through the cell membrane entering the cytosol and transfers to another cell through the opening in the cell walls called __________. However, the presence of the __________in the endodermis before the stele where vascular tissues are found, impedes the apoplastic route, thus substances move via the symplastic route to the__________. 2. Transport of substances through the XylemArrange in sequence the statements. Use 1-5.______ Absorption of water takes place due to capillary action to…Indicate the chemical structure and key properties of the following cell wall materials:hemicellulose cellulosepectin ligninsuberin tanninsIn which plant cell types are they present?Any commercial use of these substances?Suppose that a scientist exposes a leaf to CO2 labeled with radioactivecarbon-14, which is incorporated into organic compounds inphotosynthetic cells. At various times after exposure, the scientist candetermine the location of the radioactive carbon in the plant.
