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.

Give an example of an environmental condition where stomates are unable to maintaincooling of the leaf and heat stress occurs. Explain the consequences of heat stress onphotosynthesis, membrane integrity and proteins.
Acid rain can have a pH between 1.5 and 5.0. The effect of acid rain on the environment depends on the pH of the rain and the characteristics of the environment. It appears that acid rain has a negative effect on plants. The scale below shows the pH of normal rain. Provide the information requestec below that should be included in a research plan to test the effect of pH on the early growth of bean plants in the laboratory. Which of the following would be the dependent variable?
