Biology : Cell Structure And Function

*You need to write the procedure that is necessary to accomplish the tasks listed below. Test to see if your answers are correct and type your correct answer under each question. Upload your finished lab document to the dropbox.

Student instructions: Follow the step-by-step instructions for this exercise found on the worksheet below and in the virtual lab and record your answers in the spaces below. Submit this completed document by the assignment due date found in the Syllabus.

There are several sections to this lab. Find each section and complete the “Preparing for Class” sections.

Submit your document in a Word (.doc or .docx) or Rich Text Format (.rtf) for best compatibility.

You should submit your document as a Word (.doc or .docx) or Rich Text Format (.rtf) file for best compatibility.

The cell’s nonmembranous organelles include the cytoskeleton, microvilli, centrioles, cilia, ribosomes, and proteasomes. Membranous organelles include the endoplasmic reticulum, the Golgi apparatus, lysosomes, peroxisomes, and mitochondria.

You may use the lab manual, pre-lab lectures, and credible internet resources, however you may not use your cell bio lab classmates as a resource. You will most likely see this material again on the Final and I highly encourage you to work individually and seek help from myself or your TA. Plagiarism will result in an automatic zero.

When your lab report is complete, submit this document to your instructor in your assignment box.

▪ Know the functions of the various organelles, e.g., glyoxysomes, peroxisomes, ribosomes, chloroplasts, mitochondria, rough and smooth ER, Golgi, etc.

Bacteria are prokaryotic, and if you were to observe the two cells under a light microscope, you could distinguish their differences. The biggest distinguishment you can make while carefully observing the two cells, is the lack of a nucleus in a prokaryotic cell as compared to a eukaryotic. Prokaryotes also lack any membrane-bound organelles.

Which of the following structures is not normally found in the cytoplasm of a resting cell?

The cell is the smallest unit able to sustain life, and they are often referred to as the building blocks of life. There are two primary types of cell, which are categorized according to the way their genetic material is packaged, rather than size or shape. These are:

PM331 Essay: Exosomes, their cell biology, normal function in the cell, and role in disease.

Organelles are the internal structures of the cell that are important for the cell to survive. Each organelle has a specific function for the cell. The types of organelles in the cell can be different from each other depending on the type of cell. Plant cells and animal cells both have a cytoskeleton, endoplasmic reticulum (smooth and rough), golgi apparatus, mitochondrion, nucleus, plasma membrane, and ribosomes. Animal and plant cells also have vacuoles, but they are rarely found in animal cells. Vacuoles in animal cells are very small compared to the vacuoles in plant cells. Lysosomes are also rarely found in plant cells but mostly found in animal cells.
