1 Plant tissues, tissue systems, and regions • See page 50 in text You should already be getting familiar with most of the tissue types from this list. We’ve also now discussed the parenchyma, collenchyma, and sclerenchyma tissue/cell types. Through the remainder of this course, we’ll be discussing the cell types a bit more, so you should start learning which cell types you’d find in which tissue types.

2 Main Tissues of Plants Covers and protects plant surfaces – epidermis and periderm Dermal tissue system Conducting tissues •Xylem – distributes water and solutes •Phloem – distributes sugars Vascular tissue system Most extensive in leaves (mesophyll) and young green stems (pith and cortex) Ground tissue system Broader categorizations of tissue types. As you can see, xylem and phloem are both tissues, but they also belong to a broader grouping, vascular tissue. Understand the main purposes of these tissue types and how specialized they

Unformatted text preview: are. 3 Plant cells http://micro.magnet.fsu.edu/cells/plants/images/plantcell.jpg Be aware of what makes a plant cell different from an animal cell. Also be aware of what they have in common, putting special emphasis on the fact that both are eukaryotes, have plasma membranes, and mitochondria. 4 Free write: • Which has the greater mineral absorption rate, a root in a hypertonic solution (higher concentration of solute outside the cell) or a root in an isotonic solution (same concentration levels of solute inside and outside of cell)? Consider active and passive transport and how a cell deals with concentration gradients. Be aware of how the plasma membrane and the casparian strip of the endodermis play a role in determining what gets into and out of a plant’s inner vascular cells....
