Concept explainers
a.
To sketch: The plasmodesmata between adjacent plant cells.
Introduction: Plants and animals are multi-cellular organisms. Plant cells have cell wall that differentiates them from animal cells. The cell wall protects the plant cell and maintains its shape. It also holds against the force of the gravity.
b.
To list: The functions of the extracellular matrix of animal cells.
Introduction: A cell is the smallest structural, functional, and biological unit of all living organisms. It contains different organelles to carry out different functions. Some cells are specific to their functions. Unicellular organisms are raised from a single cell but multi-cellular organisms are raised from many cells. Many animal cells are also surrounded by the extracellular matrix (ECM).

- Contrast the extracellular matrix of an animal cell with thecell wall of a plant cell.arrow_forwardWhat is the similarities and differences of Plant cell and Animal cells? Explain in 1-2 sentencesarrow_forwardFrom the image, what is the normal function of the missing structure? A. A lipid bilayer controlling the movement of substances into and out of the cell B. A motor protein that "crawls" along microtubules to contract and release them, which provides movement C. A cytoskeleton element composed of tubulin subunits to provide structure for movement of the cellarrow_forward
- Compare and contrast the extracellular matrix of animals and the cell wall of plants by describing both of their structures and functionsarrow_forwardSecondary cell wall development and formation is lined and perforated by What?arrow_forwardRegarding animals cells, list what you consider to be the top 4 most important organelles and justify your answers by explaining their function and structure and what would be the consequence of a malfunction in the organelles you choose. FOR THIS DISCUSSION, DO NOT CHOOSE THE NUCLEUS.arrow_forward
- Identify the labeled parts of the plasma membrane below from the diagram.arrow_forwardEndoplasmic reticulum is an important part of endomembrane system of a cell. Explainhow the structure of endoplasmic reticulum depends on cell specialization.arrow_forwarda) What are the forces that maintain structural integrity of biological membranes?b) Explain how each force mentioned is formed in membrane lipids. c) Comment on lipid to protein ratio in the membrane of molecules that transport insoluble substances in the blood.arrow_forward
- Compare and contrast cilia and flagellaarrow_forwardAnswer the Guide Question: a) Each cell in an organism has all of the basic parts. Each has a function that benefits the other cells, how might the presence of different cell structures in plant and animal help them perform their functions as an organism. Explain. b) Why is the cell membrane considered as the guard of the cell? c) Why is the lysosome considered as the suicide bag of the cell?arrow_forwardCilia and fl agella are involved ina. forming junctions between cells.b. establishing the extracellular matrix.c. cell-to-cell communication.d. cell movement.arrow_forward
