Mitosis: Cell Phases
The phases of mitosis can be observed by staining cells of rapidly growing tissue so the chromosomes can be seen. You have read about each phase separately, but remember that mitosis is a continuous process and that the phases (designated by human observers for your convenience) really merge from one to the next.
Review the phases of mitosis in your text. Pay particular attention to the photographs of real cells undergoing mitosis.
Complete the table with the following:
• For each phase, in 40–60 words, describe in your own words (paraphrase) the major events that occur in the cell. What would you expect the cell or nucleus to look like in each phase? Could you see the chromosomes and the nuclear membrane? If you could see the chromosomes, how would you expect them to be arranged?
• Provide a drawing that you create of what the cell would look like in each phase (Suggestion – take pictures and upload the pictures and imbed them here).
• Include your references and in-text citations. APA formatted references should go at the end of this document and each response should have an in-text citation.

BIO 204 Week2 Process of Photosynthesis
Write a 750- to 1,050-word paper (in APA style – see APA sample paper), including the equations requested below, describing the important steps of photosynthesis.
Provide the equation for photosynthesis. Explain where each reactant comes from and how the plant gets it. Then, explain the importance of each product for life on earth.
What is an absorption spectra? Explain why a green leaf looks green. Is it the same reason a red leaf looks red? Explain your answer.
What is the main energy-carrying molecule in the process of photosynthesis? How does it carry energy? Where does it carry energy?
Provide the reactants and products of the light reactions. Describe how the light reactions work. Use a diagram or picture (MUST BE CITED – APA format).
Provide the reactants and products of the Calvin cycle. Describe the three phases of these reactions. Use a diagram or picture (MUST BE CITED – APA format).

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 (In APA Style – see APA sample 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 the terms xylem, tracheids, vessel elements, pit membranes, vessel, adhesion, cohesion, cohesion-tension, and transpiration. Highlight these terms within your answer.
You should have a minimum of 3 references for this assignment.
Direct Quotes are limited to 2 small quotes (less than 40 words).
Format your paper consistent with APA guidelines. Include all references and in-text citations – all should be formatted in APA style.
