P2 There are two different types of epithelial tissue these are simple and compound. Simple Epithelium- this type of epithelium tissue is from an animal consisting of one of more layers of closely packed cells. The cells can vary in structure depending on their function which may be protective, secretory or absorptive. This epithelium tissue covers external and internal surfaces of the body. Compound Epithelium – this type of epithelial tissue is made to withstand wear and tear.
| | | A) | endoplastic reticulum | | | B) | microtubules | | | C) | cytoplasm | | | D) | mitochondria | | | | | | Feedback: The cell's chemical processes take place in a semifluid material called the cytoplasm. This material provides an ideal environment for organelles because of its fluidity. | | 7 CORRECT | | This shows an example of endoplasmic reticulum. What is the significance of its structure? | | | A) | provides a location for DNA production | | | B) | helps decrease surface area | | | C) | allows selective permeability of cell membrane | | | D) | facilitates breakdown of chemical bonds | | | | | | Feedback: The pleats and folds of the endoplasmic reticulum provides a large surface area where cellular functions, such as breaking chemical bonds, can take place.
It's also found in the uterus and fallopian tubes. The movement of cilia move the ovum to the uterus. Glandular Epithelium are basically columnar epithelium with goblet cells. Some parts consist of such a large number of goblet cells that there are only a few normal epithelial cells left. They secrete substances
Endothelial lining is always present. Connective Cartilage: Cartilage is a connective tissue where the substance in abundant and of a firmly gelated consistency that endows the tissue with rigidity and resistance to compression. The cells of cartilage which are called chondrocyte are isolated in to small lacunae within the matrix. Cartilage is avascular, gaseous metabolites and nutrients can diffuse throughout the aqueous phase where the gel-like matric reaches the cells.
In this task I will outline the functions of the main cell components. Which consists of the Cell membrane, nucleus, cytoplasm, mitochondria, endoplasmic reticulum (smooth and rough), golgi apparatus and lysosome. Cells are the structural and functional units of all living organisms. Cells can take in nutrients, change these nutrients into energy and can carry out particular functions, and reproduce them if needed. Mitochondria Mitochondria Nucleus Nucleus Lysosome Lysosome Golgi apparatus Golgi apparatus Cell membrane Cell membrane Endoplasmic reticulum (Smooth and rough) Endoplasmic reticulum (Smooth and rough) Cytoplasm Cytoplasm Cell Membrane A cell membrane of the cell.
a. Afferent Lymphatic Vessels b. Efferent Lymphatic Vessels c. What is the function of the macrophages within the lymph nodes? The macrophages phagocytize foreign cells and substance trapped in the lymph node and spleen and presents them to T and B lymphocytes. d. Identify spleen
Cells are the building blocks of life. Tissue: Made from similar cells. Each organ has specific types of cells that make that particular organ and its parts. Organ: Similar types of tissue (example brain tissue, muscle tissue, bone tissue, heart tissue) makeup an organ. Organ System: Organs that work together to help an organism execute a specific function (breathing, thinking, eating, reading, writing, playing, learning, sleeping, moving, etc.)
| Vesicle | Storage in and out of the cell. | Cytoskeleton | The cytoskeleton plays a critical role in the determination of cell shape and serves as a scaffold for critical cellular enzymes and adhesion molecules. It provides structural integrity for the cell and regulates the function of many biochemical events that are critical to cellular function.
Depending on if the cell is an animal cell or a plant cell. | | Cytoskeleton | Cytoskeleton has intercellular proteins that help the cell maintain its shape and with helps with movement. | The word skeleton in Cytoskeleton reminds me of the meaning. | K Key Idea | I Information | M Memory Clue | Ribosomes | Ribosomes are protein builders. | The word Ribosomes remind me of Ribs.
| Goigi Apparatus | The main function of the Golgi apparatus is to be responsible for handling the macromolecules that are required for proper cell functioning | It packages and ships molecules made in the ER. | Lysosome | Lysosomes are spherical bag like structures that are bound by a single layer membrane, however, the lysosome shape and size may vary to some extent in different organisms. The lysosome size ranges between 0.1 to 1.2μm. | Lysosomes function as the digestive system of the cell, serving both to degrade material taken up from outside the cell and to digest obsolete components of the cell itself. | P1 tasks 2 Organs | Anatomy | Physiology
