Paper ), including the pictures requested below , describing primary 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 . Describe how glucose ( sugar ) is transported within a plant . Use the terms sieve cells , sieve tube members , companion cells , sieve pores , sieve areas , pressure flow hypothesis , sources ( provide examples ), sinks ( provide examples ), STM / CC complex , and osmotic potential in your response . Highlight these terms within your answer . Explain how water and minerals are absorbed and transported by the root system into the xylem and from the xylem into leaves . Include
