1. Mitochondria and chloroplasts reproduce the same way free-living bacteria do—by _____________.
My answer: Binary fission.
2. The tropism that allows seedlings to find their way out of the soil and into the sunlight is _________________.
My answer: Positive tropism.
3. The seahorse is an unusual example of a(an) _______________species because the male incubates the eggs in a pouch before giving birth to fully formed live offspring.
My answer: Hippocaumpus
To verify your answers:
1. Yes, you are correct. Mitochondria and chloroplasts, which are organelles found within cells, reproduce through a process called binary fission. Binary fission is a form of asexual reproduction where a single organism divides into two identical daughter cells.
2. However, your answer for the second question is not accurate. The tropism that allows seedlings to find their way out of the soil and into the sunlight is called positive phototropism. Positive phototropism is a growth response in which the plant grows toward a source of light. In the case of seedlings, they exhibit positive phototropism to ensure that their leaves receive ample light for photosynthesis.
3. Although you have the correct concept, your answer is not accurate. The correct term for the description provided is "seahorse." Seahorses are a unique example of a species where the male incubates the eggs in a pouch and gives birth to fully-formed live offspring. The term "Hippocaumpus" seems to be a combination of "Hippocampus," which is the scientific name for seahorses, and "caumpus," which is not a valid term.
