Is it possible to see cells in a leaf using the stereoscopic microscope?
We couldn’t see cells at low power in stereoscopic. 2. The light source in stereoscopic can be directeed down onto as well as up through an object, which permits the viewing of objects too thick to transmit light.
What was the approximate size in μm of one Elodea leaf cell?
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).
What magnification do you need to see chloroplasts?
Now examine the specimen with your microscope under low-power (100X-150X). If your microscope has a diaphragm, keep it on a low (smaller) setting. Find a good area, and rotate to high-power (400X). You should see a pattern of rectangular cells.
What property of the Elodea leaf makes it ideal for use in microscopy and why is this property helpful in light microscopy?
The leaves of Elodea are only two cells thick and are ideal for the microscopic study of the effects of osmotic solutions. Freshwater is hypotonic to Elodea A hypotonic solution is a solution that contains less (hypo) solutes than the cytoplasm of the cell.
What magnification can a microscope see cells?
400x
Magnification of 400x is the minimum needed for studying cells and cell structure.
How thick is an Elodea leaf?
The leaves of Elodea are quite thin at only two cell layers thick.
What did you observe on the Elodea leaves?
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. Under a microscope the green chloroplasts inside of the cell can be observed.
What is Elodea leaf?
Elodea are herbaceous perennials that feature dark green leaves arranged in whorls of two to seven along the stem. Plants are usually dioecious (individuals bear either male or female flowers only) and produce seeds in ellipsoid or oval capsules.
What is an Elodea leaf?
Why do chloroplasts move Elodea?
Chloroplasts do move in a cell. Observing chloroplasts in movement in an elodea cell is like watching a busy, bustling mass of pedestrians from a building high above. The actual cause of the motion isn’t yet clear, but it does alter with heat and light and is changed by increases and decreases in fluid content.
Is Elodea a plant or an animal?
Elodea, like any plant or animal, causes huge problems when introduced to places outside its natural habitat. In Europe and parts of the Americas, it clogs waterways because of a lack of natural predators, and chokes out native plants and the animals who depend on them.
Does Elodea have a cell wall?
The elodea cell will have a central vacuole in addition to chloroplasts . Plant cells also have a cell wall which is not a structure found in animal cells.
Where do you find Elodea leaf?
Elodea has only 3 leaves in the whorl and no midrib teeth. Where Does it Grow? Elodea can be found in wet mud along sluggish streams, seepage areas, and marshes . Pros and Cons of Elodea
Is Elodea plant a fully submerged plant?
The Elodea plants are totally submerged plants, They have got weak roots because they are not needed to fix the plants or to absorb the water. The leaves of the Elodea plants are small-sized, thin and ribbon-like, So, They will not be cut by the water currents.
