Onion and cheek cell lab report conclusion

CONCLUSION

In conclusion, the ability to determine the functions and parts of compound microscopes and

understanding of the proper use and the maintenance of the light microscope and learn how to observe

a wet mount slide preparation for plant cells.

The Elodea plant is commonly used for aquariums. Its leaves are only 2 cells thick and are ideal for

studying the effects of osmotic solutions.The cell membrane is a part of the cell's structure that controls

the flow of materials out of the cell.Treating cells with a hypotonic solution causes the water to move

into the cell. This causes the cell to swell as the water moves into the cell. In plants, this produces a rigid

membrane that prevents the water from flowing against the walls. When the salt solution is introduced,

the salt ions outside the cell membrane induce water molecules to escape through the cell membrane,

causing the cell to shrink into a blob in the cell wall's centre. Osmosis is the movement of water

molecules.

An onion is made up of several layers that have been separated by a thin membrane. This layer can be

easily removed using tweezers. It's also important to avoid damaging the objective lenses by not placing

the optical tube too close to the slide . Although onions contain less starch than potatoes and other

plants, the dye (iodine) allows the tiny starch molecules to be seen under a microscope. Students will not

see chloroplasts on their slides, despite the fact that onions are plants.This is due to the fact that the

chloroplast required for photosynthesis is predominantly present in the onion's leafy section, which is

exposed to the sun, but not in the bulb, which is underground and out of reach of the sun. Students will

also notice that plant cells have a more regular shape than animal ones. This is because they contain a

cellulose-based cell wall that keeps them in shape. An onion is a multicellular plant organism (one with

many cells). An onion peel cell has a cell wall, cell membrane, cytoplasm, nucleus, and a big vacuole, just

like any other plant cell. Plant cells can be distinguished by the existence of a cell wall and a big vacuole.

The cells of the human cheek lack a cell wall, as do all animal cells. The cytoplasm is surrounded by a

semi-permeable cell membrane. In an animal cell, the vacuole is smaller or not present. Animal cells are

distinguished by the absence of a cell wall and the presence of a conspicuous vacuole.

What is the conclusion of human cheek cell?

Answer: As in all animal cells, the cells of the human cheek do not possess a cell wall. A cell membrane that is semi-permeable surrounds the cytoplasm. ... The absence of a cell wall and a prominent vacuole are indicators that help identify animal cells, such as cells seen in the human cheek.

What is the conclusion of the observing nucleus in cheek cells?

Answer. Cheek cells are eukaryotic cells (cells that contain a nucleus and other organelles within enclosed in a membrane) that are easily shed from the mouth lining. It's therefore easy to obtain them for observation.

What conclusion was made by the study of onion peel under microscope?

Conclusion:As cell walls and large vacuoles are clearly observed in all the cells, the cells placed for observation are plant cells. - Onion epidermal peel is made up of rectangular shaped cells. A nucleus, a central vacuole, a thin layer of cytoplasm, and a cell wall make up each cell.

What is the aim of onion experiment?

Activity: Observing Onion Cells. Goal: To observe, identify and describe the basic organelles of a non-green plant cell. Background Information: All living things are made up of small units called cells. That is, cells are the basic building blocks of living things just as atoms are the basic building blocks of matter.
