-Some additional proof of the endosymbiotic theory includes the similarity in DNA between bacteria and mitochondria and cyanobacteria and chloroplasts.

Explanation;

-According to the endosymbiotic theory; mitochondria and chloroplasts contain their own circular DNA, similar to DNA in Bacteria, Both mitochondria and chloroplasts are surrounded by two membranes: inner and outer membrane, mitochondria are about the same size as bacteria and also mitochondria appear to have been derived from purple bacteria and chloroplasts derived from photosynthetic bacteria.

Stacey wants to know if plants have the same phototrophic reaction from artificial light as they do from natural light. Using st

joja [24]

Scientific method includes some steps that are necessary for conducting the successful experiment.

1. Make an observation

You observe the growth of the plant under the influence of light (phototropic effect) and you notice that some plants successfully grow under artificial light. You want to compare that growth with growth under the sunlight.

2. Ask a question

How does the light influence plant growth?

Are the wavelengths of the light important?

Is natural light source (sun) better for plant growth...

3. Form a hypothesis - it is a testable potential answer to the question

For example: Sunlight induces higher phototropic reaction.

4. Make a prediction

Sunlight is richer in red and blue hues which are both extremely important to plant growth.

5. Test the prediction

Design an experiment by putting one pot with beans outside on sunlight and other under the light bulb. Other conditions such as water must be the same. Monitor their growth for about 2 weeks and measure the results.

6. Analyze the data and make a conclusion.
