Name four organelles of the cell and give their basic structure and function.
Name the four functional categories described in the text for eukaryotic organelles. Site example organelles for each category. Describe the structural similarities that underlie the function of each group. Give examples of each subclass. Explain how each of the categories works together to produce the emergent properties at the cellular level.
Cell Organelles and their Functions This unit we are learning about cells and the organelles contained within. In this Discussion, we’ll focus on the functions of the various organelles and cell structures: Cell membrane | Mitochondria | Plant cell wall | Plant chloroplast | Nucleus | Lysosomes | Nuclear envelope | Rough endoplasmic reticulum | Golgi apparatus | Smooth endoplasmic reticulum |Cytoskeleton | Cilia and flagella Select four of the organelles or structures above and briefly describe where each is...
Which structure(s) is/are involved with maintaining the position of organelles within a cell? A) Cell wall B) Endoplasmic reticulum C) Mitochondria D) Golgi apparatus E) Intermediate filaments
The eukaryotic cytoskeleton A. Anchors organelles B. Provides structure and shape to the cell C. Aids in cell movement D. All of the above
1. name 3 kinds of organelles that are components of the cell's endomembrane system. briefly describe the function of each component. 2. define cytoskeleton. how does it aid in cell function? 3. distinguish between chromosomes and chromatin.
(Isolation of cell organelles by differntial centrifugation ) Name to the experiment Pre Lab Preparation: 1. Prepare a diagram or flow chart that shows the centrifugation conditions and fractions generated by the various steps in differential centrifugation, 2. What is the purpose of dehydrogenases in cellular respiration?
Cell Structure and Function: 1. What is the basic structure of the cytoplasmic membrane, and what are its three critical roles in bacteria? (5) 2. What is the role of peptidoglycan in the cell, what are the two polysaccharides which make up the backbone, and what is the advantage for a cell lacking peptidoglycan? (4) 3. What is the difference between Gram-negative and Gram-positive Bacteria in the crosslinking of peptidoglycan? (2) 4. How and why does the Gram stain differentially...
Cells are the basic units of structure and function in all organisms. A key feature in the life cycle of plants is the alternation of multicellular haploid and diploid generations. Imagine a lineage of flowering plants in which mitotic cell division did not occur between the events of meiosis and fertilization. Describe how this change in the timing of cell division would affect the structure and life cycle of plants in this lineage.
what are endospores made of You have been assigned two cell structures/organelles to learn more about in. During this activity, you will share the following information with other teaching them what you have learned, so it's really important that you questions! Use chapters 6 and 27 in your text as your information sour but you are responsible for verifying the accuracy of the information Assigned cell structures/organelles: Are these considered TRUE organelles or "just" cell structures? Your structures/organelles are made...
What is the function and basic structure of the nervous system?
