Answer:
Structures that are present in plant cells and animal cells are membrane-bound organelles. For example, nucleus, mitochondria, and/or chloroplasts are not present in bacteria.
Explanation:
This is because bacteria are prokaryotic cells while plants and animals are eukaryotic cells.
Prokaryotic cells lack membrane-bound organelles like eukaryotic cells. Prokaryotic cells do not have a nucleus or organelles like mitochondria and chloroplasts.
Answer: The molecules of chlorophyll contained in the chloroplasts absorb energy in the form of light from the sun. This is the process called Photosynthesis, by which plants convert energy from the sun. It is the process that allows plants to create organic molecules that they use as fuel.
Explanation:
During the process of photosynthesis, plants capture light energy and use it to convert water, carbon dioxide, and minerals into oxygen (released into the air) and glucose (stored in the plant and used as food). The photosynthesis process occurs in all plants and algae, as well as in some bacteria species.
The heavy bombardment of terrestrial planets by asteroids from space has contributed to the formation of the early evolved crust on Earth that later gave rise to continents - home to human civilization.
Diffusion across the alveoli
Convergent evolution.
Similar looking organisms develop similar structures based on their niches, but it does not imply common ancestry.
