Microbiology experiment report

Experiment name: Observation of chloroplast and cytoplasmic flow using a high power microscope

First, the purpose of the experiment
1. Initially master the use of high power microscopes.
2. Observing the morphology and distribution of chloroplasts of higher plants in cytoplasmic matrix. II. Experimental principle The chloroplasts of higher plants are ellipsoidal. Under different light conditions, the chloroplast can move and change the ellipsoid.
In this way, it can accept more light without being burned by strong light. Under strong light, the chloroplast faces the light source with its ellipsoidal side; under weak light, the chloroplast faces the light source with its ellipsoidal front. Therefore, the shape of the chloroplast ellipsoid in the leaflet is not exactly the same in the different light conditions.
The cytoplasm in living cells is constantly flowing, and observing the flow of cytoplasm can be marked by the movement of chloroplasts in the cytoplasmic matrix.
Third, the material utensils of the leaves, fresh spirulina, microscope, slides, coverslips, dropper, tweezers, blades, petri dishes, pencils four, the experimental process
1. Making temporary loading of scorpion blades
2. Observing chloroplasts with a microscope
3. Making spirulina leaves for temporary loading
4. Microscopic observation of cytoplasmic flow physics experiment report · chemical experiment report · biological experiment report · experimental report format · experimental report template

V. Discussion
1. Is the chloroplast in the cytoplasmic matrix stationary? Why?

2. What is the relationship between the morphology and distribution of chloroplasts and the function of chloroplasts?

3. The cytoplasm of plant cells is constantly flowing, what does it mean for living cells to complete life activities?

4. Draw a leaf cell with a pencil and mark the general flow direction of the chloroplast.
