Introduction: The cell is the basic unit of life and the individual part of which the whole organism is composed.
Many of the substances in a cell are organized into . This Elodea leaf cell exemplifies a typical plant cell. It has a nucleus, and a stiff cell wall which gives the cell its box-like shape.
The numerous green chloroplasts . Table Diagram your microscope observations in the circles.
Table At an appropriate objective setting, choose three to ten Elodea cells. Count the.
(hint: think about where you find onions) 3. Which type of cell was smaller – the onion cells or the elodea cells?
7. 4. Fill out the Venn Diagram.
Examining elodea (pondweed) under a compound microscope. solution) and a coverslip and observe the chloroplasts (green structures) and the cell walls.A “typical” Elodea cell is approximately millimeters long (50 micrometers long) and millimeters wide (25 micrometers wide).
As you can see in the image, the shapes of the cells vary to some degree, so taking an average of three cells’ dimensions. Elodea is a genus of 6 species of aquatic plants often called the waterweeds described as a genus in Elodea is native to North and South America and is also widely used as aquarium vegetation.
It lives in fresh schematron.org: Hydrocharitaceae. Elodea cells also contain a vacuole, which is filled with a liquid called cell sap that is primarily made up of water. The structure of elodea cells also differ from onion cells.
Elodea cells are in two layers of varying sizes; one layer is long and narrow, and the second layer is short and wide. An Elodea cell consists of a semi-permeable cell wall, which contains a membrane, enveloping the cytoplasm, in which a nucleus, vacuole, chloroplasts and mitochondria are located. 3. Which type of cell was smaller – the onion cells or the elodea cells?
How do you know? 4. Fill out theVenn Diagram below to show the differences and similarities between the onion cells and the elodea cells.
5. Did you notice the chloroplasts moving within the cytoplasm of the elodea plant?
Do they all move in the same pattern or direction?Ms. Wheeler / OsmosisElodeaMakeupLabPlant Cell Lab – Onion and Elodea
