Onion cell lab report conclusion Rating: 5,6/10 306 reviews

In conclusion, the onion cell lab was a valuable exercise in understanding the basic structure and function of plant cells. Through the use of a microscope, students were able to observe the various organelles present in the cells of an onion, including the cell wall, cell membrane, cytoplasm, and nuclei.

One of the most notable observations was the presence of the cell wall, which provides structural support and protection for the cell. The cell membrane, on the other hand, serves as a barrier between the internal and external environments of the cell, regulating the movement of substances in and out.

The cytoplasm, which is the semi-fluid substance that fills the cell, was also clearly visible under the microscope. This substance contains various organelles such as the endoplasmic reticulum, Golgi apparatus, and mitochondria, which are responsible for carrying out important functions within the cell.

Finally, the nuclei of the onion cells were also visible, containing the genetic material necessary for the cell's growth and reproduction.

Overall, the onion cell lab was a valuable learning experience that allowed students to gain a greater understanding of the basic structure and function of plant cells. It also provided the opportunity for students to develop their microscopy skills, which are essential for many scientific fields.

In conclusion, the onion cell lab was a valuable learning experience that allowed us to observe the structure and function of plant cells. By using a microscope and prepared slides, we were able to closely examine the cells of the onion and identify their various organelles.

One of the main features we noticed in the onion cells was the presence of a cell wall, which provided structural support to the cell and helped it maintain its shape. We also observed the presence of a cell membrane, which controls the movement of substances in and out of the cell.

Inside the cell, we were able to identify the cytoplasm, which is a gel-like substance that contains all of the cell's organelles. We also noticed the presence of several organelles, including the nucleus, which contains the cell's genetic material, and the mitochondria, which are responsible for producing energy for the cell.

Another important feature of the onion cells was the presence of chloroplasts, which are responsible for photosynthesis. These organelles contain pigments called chlorophyll, which allow the plant to absorb light energy and convert it into chemical energy.

Overall, the onion cell lab provided us with a better understanding of the structure and function of plant cells. It also helped us appreciate the complexity and diversity of cell structure and function in the living world.

Lightly stained cytoplasm is observed in each cell. Onion is a eukaryotic plant that contains multicellular cells. Whereas, a cell without a genuine nucleus or organelles that are membrane-bound is referred to as a prokaryotic cell. Cell Organelles Have you ever wondered what the inside of a cell looks like? An error in the experiment would've included only having one trial, and not repeating any. However, the nucleus appears grainy due to chromosomal condensation.

Two more slides were provided these are the yeast and protozoa cells. The procedure was not as descriptive as possible, and could have been more explanatory, and instructive. Some of the cell walls are very thin in some plants. Also the observation, result and precautions of the experiment are also discussed. The Onion Vs Cheek Cell Lab is a powerful way to have students examine the similarities and differences of plants and animal cells and practice identifying basic cell parts.

Wipe both sides dry with a paper towel. In the red onion you can see effects promptly when the onion cells are placed in different type of solutions. Examine under low power. The main difference between onion cell and human cell is that the onion cell is a plant cell with a cell wall made up of cellulose whereas the human cheek cell is an animal cell without a cell wall. Vacuoles are formed by the fusion of multiple membrane vesicles and are effectively just larger forms of these.

Also present in the onion cell, is a well-developed. Another error could've been contaminations with the contact of the cells with skin, and or contaminations with the dropper used for the experiment. The two types of cells that differ in size and structure are Prokaryotic and Eukaryotic cells. We would also see a cell membrane for the cheek cell and cell wall for the onion cell. The water potential of the solution at equilibrium will equal to the water potential of the potato cells.

Onion epidermal cells exist as a single layer that serves as a protective skin. NAME: Sephia De Boulet STUDENT ID: 95263 OBJECTIVES: To prepare and observe the onion peel and a human cheek cell under a microscope. FAQS About Onion Cells Under Microscope What do onion cells look like? Writing A Biology Lab Report Dissertation Conclusion Inside. In this stage, it's also possible to clearly identify the chromatids given that the process occurs in the cytoplasm. Requirements We need the following glassware and reagents to prepare a temporary slide of an onion peel. This is because water moves from inside the vacuole, to the cell since the saline solution is entering the vacuole.

Centre this group and change to medium power. It is also called cytosol. At the very least, this will offer a more defined view of the cellulose. This occurs when the cell is exposed to a hypotonic solution causing the water to diffuse into the cell up to a point when the volume capacity exceeds what the cell membrane can hold. TITLE: Animal and Plants cells INTRODUCTION: From this lab, we should learn how to properly use a microscope and examine the cells of an onion peel and also a human cheek cell MATERIALS: Microscope Distilled water Forceps Watch glass Glass slide Dropper.

Visualizing Onion and Human Cells Expand. This will give you a record of the original appearance of the onion cells. Estimate the length of a single cell in micrometers pm using the method described in class. Unlike the onion skin cells, the cheek cells were more spread out from each other and they all had a round shape. Aim: The aim of this investigation is to identify the cells within an onion skin using a light microscope. Similarities and Differences between Plant and Animal Cells Animal and plant cells have a number of key similarities, but also some noted differences.

Osmosis is a type of passive transport involving movement of water molecules across a partially permeable membrane. Surface area of an object was compared to its volume and weight in this experiment. In the onion root tips cells, it has the cell wall, so The Biology Project is fun, richly illustrated, and tested on 1000s of students I did an experiment for a potato After conducting the cell lab exercise, students will be able to identify the cell membrane, nuclei and cytoplasm in cheek cells and nuclei, cell wall, cytoplasm and chloroplasts. Then, wash the separated peel in the Petri plate containing water. Obtaining a thin membrane from a bulb of onion is easy with the use of a pair of tweezers. A large vacuole is present at the centre of each cell, and is surrounded by the cytoplasm.
