and secondary growth in plants and the journey of water and sugar molecules in plants . Include the following points and principles :
Part 1 : Primary and Secondary Cells and Tissues in Plants
The three types of plant cells are parenchyma , collenchyma , and sclerenchyma . For each , discuss the basic structure , function , the different types for parenchyma and sclerenchyma , and where in the plant they can be found .
Include a picture of a cross section of a leaf ( Include an APA formatted in-text citation ). Label the following structures and then describe each of the following : epidermis , cutin , cuticle , guard cells , stomata , cortex , and vascular bundles .
What is the function of a lenticel ? How are intercellular spaces important for this function ?
Include a picture of a stem and label the nodes , internodes , apical meristems , leaf buds , and flower buds .
Describe growth by apical meristems .
Include a picture of a cross section of secondary growth in a woody species ( Include an APA formatted in-text citation ). Label the primary xylem and phloem , secondary xylem and phloem , fascicular cambium , and interfascicular cambium .
In woody species , additional tissues are produced in the stem and root by two additional meristems . Name these meristems , and describe how they add secondary growth to the plant .
Part 2 : Water , Sugar , and Mineral Transport in Plants
Explain how each of the following mechanisms transports substances within the plant : symplast , osmosis , molecular pumps in the membranes , transport vesicles fusing with the plasma membrane , apoplast , and transfer cells .
Describe the costs and benefits of transpiration for plants .
