What is the function of Elodea cells?
Explanation: The elodea like all green plants uses the process of photosynthesis to produce organic energy molecules. Oxygen is a by product of the process of photosynthesis. Oxygen can be observed leaving the elodea cells.
How are Elodea and onion cells different from other cells?
Onion cells have a round and rectangular-shaped structure, and elodea cells are stiff-rectangular shaped. The elodea cell comprises of chloroplast spot, which is essential for them to sustain. On the other hand, onion cells are devoid of chloroplast spots as the growth of these cells occurs under the ground.
Do Elodea have cell walls?
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 allow the cell to make its own food (by photosynthesis). Like animal cells, the cytoplasm of this plant cell is bordered by a cell membrane.
What has happened to the Elodea cell?
When the Elodea was placed in the salt solution, the vacuoles disappeared and the protoplasm came away from the cell wall making the organelles appear to be clumped in the middle of the cell. Such cells are said to be plasmolyzed. Therefore, if it were placed in a hypertonic solution it would lose water and shrivel.
Does Elodea cells have a central vacuole?
Lack a cell wall, and have no central vacuole. This Elodea leaf cell exemplifies a typical plant cell. It is transparent, but you can see where it’s pressing the chloroplasts up against the cell wall, especially at the ends of the cell. Like animal cells, the cytoplasm of this plant cell is bordered by a cell membrane.
How big is an Elodea cell?
approximately 0.05 millimeters long
What’s the Size? A “typical” Elodea cell is approximately 0.05 millimeters long (50 micrometers long) and 0.025 millimeters wide (25 micrometers wide).
Why is an Elodea cells smaller than onion cells?
What is the difference in size and shape between the onion and the Elodea cells? The onion cells are slimmer and smoother, but they are also connected (like bricks) like the Elodea cells. Elodea cells are more square and green and bigger. A cell wall, a nucleus, a cell membrane and a cytoplasm.
Why do Elodea and onion cells have more consistent shapes than human epithelial cells?
Why do Elodea and onion cells have more consistent shapes than human epithelial cells? Elodiea cells and onion cells have more consistent shapes because they both contain cell walls which mainteains its shape. Human epithelia cells lack cell walls which is why they contain more different shapes.
How do the Elodea cells in a hypertonic environment differ from the Elodea cells in a hypotonic environment?
Placing Elodea cells into 100% water, which is more hypotonic than freshwater, also causes water movement into of the cells resulting in the swelling of the cells. Thus, a hypertonic solution has less water than the cell and water moves (diffuses) out of the cell by osmosis.
What happens to Elodea cells in a hypertonic solution?
What is the function of an Elodea cell?
All organisms are composed of cells.
Why do chloroplasts move in Elodea?
Why do chloroplasts move in elodea? Students will sometimes notice that the chloroplasts in a cell are moving. This results from movement of the cytoplasm, which is termed cyclosis. As the cytoplasm flows, the chloroplasts move along with it. Light and heat stimulate cyclosis.
