Seek detailed answers to various questions of senior two students.
The first topic is centrosome and ribosome. (phospholipid bilayer is the basic skeleton of unit membrane, so whether it contains phospholipid bilayer depends on whether it has membrane structure)

The second question is wrong. Because the place where aerobic organisms breathe is mitochondria and cytoplasmic matrix, both of which can produce ATP;; Moreover, the photosynthesis of plants can also produce ATP, and the place is chloroplast.

Question 3: Escherichia coli has mitochondria. Because the only organelle in prokaryotic cells is ribosome. Here, Escherichia coli is a prokaryote, and yeast is a fungus and a eukaryote.

Question 4: Choose mushrooms. First of all, heterotrophy means that inorganic substances cannot directly synthesize organic substances, and ready-made organic substances must be ingested to maintain life. Autotrophic means that most green plants and a few kinds of bacteria use light energy or chemical energy as energy source and carbon dioxide in the environment as carbon source to synthesize organic matter. Animals, fungi and most bacteria come from heterotrophs, while plants, cyanobacteria (capable of photosynthesis) and chemosynthetic bacteria (capable of chemosynthesis) belong to heterotrophs. Nitrifying bacteria here belong to chemosynthetic bacteria, and Chlorella belongs to plants, so they are all autotrophs. Lentinus edodes is a fungus and belongs to heterotrophic bacteria.

As for prokaryotes, it refers to organisms that do not form nuclei, such as bacteria. The cyanobacteria here belong to bacteria, so they are prokaryotes. Protozoa are eukaryotes, mostly single-celled organisms. Protozoa and prokaryotes are not the same classification standard. But protozoa must not be prokaryotes, but belong to eukaryotes. Chlorella here belongs to algae plants.

Finally, choose chloroplasts (containing chlorophyll, carotenoids, lutein and other pigments) and vacuoles (containing anthocyanins and other pigments).
