iren [92.7K]

Answer:

The distribution of chloroplasts in each algae cell was approximately the same.

The number of bacteria grouped at each wavelength (color) was approximately proportional to the amount of oxygen produced by this part of the algae.

Explanation:

Photosynthetic pigments absorb blue, red and green lights. The wavelength of light that is the most effective in driving photosynthesis is 420 nanometers, which corresponds to blue light.

The wavelength of 475nm and 650nm are most effective in driving photosynthesis.

What components of the eukaryotic cell were visible in the onion root tip? Which components were not? Why do you think some comp
ruslelena [56]

Looking at the onion root tip under the microscope you can see large, rectangular cells with visible distinct cell walls surrounding it (cells have a more regular shape because of the wall). Inside the cells, you can notice darkly stained nucleus, large vacuoles at the center and sometimes small granules within the cytoplasm. Looking the onion root tip under the microscope is often the way to observe mitosis. Usually, you cannot see organelles such as mitochondria, ribosomes, rough and smooth endoplasmic reticulum, centrioles and Golgi body as they appear translucent and because are too small to be seen under the light microscope (electron microscope required). Also, chloroplasts are not present in an onion cell because it is not a photosynthetic cell.
