plant (agapanthus) cells and animal (human cheek) cells to be examined. The shapes shown in the results were these two types of cells. The cell that was dyed pink was a human cheek cell, and the regular-shaped cell was an agapanthus cell. The basic structure of an agapanthus cell and cheek cell could easily be seen. It is obvious that the individual cells were more detailed when a higher magnification was used to observe the cell samples. From the highest magnification of the light microscope when

Preponderantly, the nucleus is a specialised double-membrane bound organelle which serves a vital role in eukaryotic cells. The functions of the nucleus include duplicating & storing genetic information, and coordinating cell activities such as synthesising proteins, growth, cell reproduction, and intermediary metabolism. Structures which make up the nucleus comprise a double membrane that circumscribes the entire organelle as well as isolating it’s placates from the anatomical cytoplasm, and the

To which structure would you assign the function of secretion activities leading, for example, to the formation of a new cell wall in plants? A. Golgi vesicles B. Nucleus C. Lysosomes D. Smooth ER E. Mitochondrial cristae There are two types of cells: Prokaryotic and Eukaryotic cells. Prokaryotic cells do not have a central nuclei nor membrane closed organelles. For Eukaryotic cells, they contain internal membranes to house multiple organelles. Each structure in a eukaryotic cell has a significant

are smaller in size and have simpler structures, whereas eukaryotic cell are bigger and have a more complex structure. 2. Eukaryotic cells have many types of organelles, whereas prokaryotic cells lack most organelles. 3. Prokaryotic cell have DNA, which is constructed in the nucleoid region. It is not enclosed by the membrane; the eukaryotic cells have DNA and are in the nucleus, which is enclosed by the membrane. Choose two internal structures of prokaryotic cells and three from

Cell Structures Instructions: Your lab report will consist of the completed tables. Label each structure of the plant and animal cell with its description and function in the provided tables. When your lab report is complete, submit this document to your instructor in your assignment box. 1. Animal cell: Observe the diagram that shows the components of an animal cell. Using the textbook and virtual library resources, fill in the following table: Animal Cell Number Cell Structure Description

molecular soup in which all of the cell's organelles are suspended and held together by a fatty membrane. The cytoplasm is found inside the cell membrane, surrounding the nuclear envelope and the cytoplasmic organelles. The cytoplasm, as seen through an electron microscope, appears as a three-dimensional lattice of thin protein-rich strands. These lattices are known as microtrabecular lattice (MTL) and serves to interconnect and support the other "solid" structures in the cytoplasm. In other words, the

surface area becomes insufficient to exchange the materials that the volume of the cell requires. Pg. 66 Q. 1-2 Q1. Explain the major differences between a prokaryotic and eukaryotic cell. Prokaryotes have no nucleus and no membrane-bound organelles like mitochondria, chloroplasts, etc. Prokaryotes are unicellular whereas eukaryotes can form multicellular organisms. Most prokaryotes have a single loop of DNA for their genome while most eukaryotes have multiple pieces of DNA inside the Nucleus

Cell Structure and Function AbstractThis report is about cell structure and function. The cell is the basic unit of life. All living things are madeof cells. By doing this lab, I hoped to learn how a cell looked and how it functioned. I also wanted toknow the differences between prokaryotic cells and eukaryotic cells Introduction The concept of this lab is producing a replica of an animal cell, and a plant cell. Producing the models of the cells helps to provide a better understanding of each
