Consider the following scenario A plant cell is placed in a 80 salt solution The 80 salt solution causes plasmolysis to occur Therefore the 80 salt solution is relative to the fluid inside the cell intracellular fluid Osmotic O Hypertonic O Hypotonic OHdrolytic Isotonic

spore cytoplasm the meristem that builds protoderm procambium and ground tissues the haploid female gametophyte before fertilization Question 13 1 point Listen In order to move materials long distances through the plant body the contents of sieve elements are pulled under tension and the contents of the tracheary elements are pushed under pressure True

In the plant world it is usually advantageous to be taller than the other nearby plants because OA reproductive structures like pollen and spores can be dispersed for greater distances B it is a photosynthetic advantage to not grow in the shade of other plants C being exposed to the wind allows transpiration to work better to control water loss D all of these A B C are advantages E both A and B are advantages while C is a disadvantage
