Examining Primary and Secondary Growth and Movement of Sugar and Water
Examining Primary and Secondary Growth and Movement of Sugar and Water
Review the major steps of water molecules’ journey from soil to a tree and into leaves. Describe how sugar from photosynthesis is transported throughout the plant.
Write a 1,000- to 1,500-word 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:
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 stem. 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. Label the primary xylem and phloem, secondary xylem and phloem, fascicular cambium, and interfascicular cambium.
