You are watching: Groups of similar cells that perform specific tasks make up
| BACKGROUND: |
Cells room the simple unit of living systems, however obviously there"s a lot more to an organism than simply cells. Cells are the structure blocks the are provided to create larger teams of cells which perform much more specific tasks.
The 2nd level of company is the tissue. A organization is a group of similar cells that occupational together to perform a particular job. Remember the there are dedicated cells in multicellular organisms, because that example, nerve, muscle, and also blood cells. Tissues function to perform numerous tasks that are too complex for a solitary cell come perform. Tissues are supplied for support, movement, secretion, protection, growth, and reproduction. Committed cells form committed tissues such together blood tissue.
A group of organization working with each other to perform a specific function is called an organ. Organs space the 3rd level that organization. Instances of organs include the skin, heart, eye, stomach, and lungs. The intricacy of guts is a characteristic that is supplied to separate groups of organisms.
The skin is a large organ with numerous different cells. As part of this lab, students room to look at their skin cell at various locations on their bodies and also then to compare the same locations on their partners. The skin is the largest organ of the body and is really complex. It wraps the adult body in about 20 square feet the tissue and weighs some seven pounds. The skin has actually 3 layers, however, college student will just be dealing with the epidermis, or the external layer. The outer skin is composed of dead cells the are always being worn off. We shed our skins continuously, not all at once but tiny by little, which go on mostly unnoticed.
PROCEDURE:have students look in ~ the prepared slides of the various groups. See if they have the right to predict even if it is something is a entirety organism, appendage, cell, organization or organ. An appendage is an auxiliary part of the main body. Appendages can contain part of an organ, depending on the kind of organism. Student will likewise see examples of the entirety organisms and also synthetic substances. Perform the answer
Photomicrograph that bird kidney, showing the different varieties of tissues consisting of this organ.
POLLENS and also SPORES -
Tulip pollen - cell leaf spore- cell Pine tree pollen-cell Orange pollen - cabinet Pollen that lily - cabinet Sunflower pollen - cell party brush spore - cabinet Fern spore - cell
Dragon paris Wing - appendages work Bee wing - appendages punishment antenna - appendages bee abdomen - appendages leg of butterfly - appendages soup of butterfly - appendages soup of locust - appendages leg of honey bee - appendages
Common red sponge - organization Angora hare hair - tissue Ant- entirety Mouse fur - tissue Plant louse - whole} Fruit paris - totality Shrimp egg - cell Silk worm larva (moth) - whole
Stem that corn - organization Leaf of nerium - organization Onion rind - tissue Silver berry scaly hair - tissue Pine wood - tissue Camellia leaf section - tissue Bamboo shoot - tissue Sponge gourd - tissue
Panya - organization Nylon - synthetic Wool - tissue Handmade file - organization Hemp fiber - tissue Silk ingredient - tissue Cotton fiber -tissue Bemberg - synthetic
Cat hair - tissue Canary feather - tissue Dog hair - tissue lamb hair - tissue Goldfish range - organization Hare hair - organization camel hair - organization feather fowl suggest - tissue
college student will find that the shapes of the cells readjust from one component of the human body to the other. Remember that the skin is our body’s largest organ. Have actually the students location the Swift GH microscope directly on the skin therefore students deserve to record what castle see. The vital point is simply to observe that there room differences. Have them to compare the palm of your hand, fingertips, back of hand and leg. Just have actually them draw in the appropriate area top top the lab paper what they see. If lock compare with their neighbors, lock will notice that the skin cells from different parts that the exact same body do change, but that the shape is comparable from different people.
