What are some specimens that are light sensitive?
Some specimens that are light sensitive include certain types of algae, fungi, bacteria, plants, and insects. These organisms may exhibit phototropism, which is the ability to move or grow in response to light stimuli. Exposure to certain wavelengths of light can also impact the growth, development, and behavior of these light-sensitive specimens.
Why must specimens viewed with a compound microscop be thin?
Specimens viewed with a compound microscope must be thin to allow light to pass through them. This ensures that the light rays can illuminate and pass through the specimen, which is necessary for magnifying the image and producing a clear view under the microscope. Thicker specimens would scatter or block the light, resulting in a blurry or dark image.
