<span>Type 2 alveolar cells or pneumocytes are the cells responsible for secreting pulmonary surfactant. Their function is important as the pulmonary surfactant is required to decrease surface tension within the alveoli. They are capable of cell division which in turn produces more of these alveolar cells when there is damage to the lung.</span>
X-gal is included in the growth medium on which cells transformed with bacterial plasmids are grown. The reason x-gal is included is to identify bacteria that contain a recombinant plasmid.
<h3>What are
cells?</h3>
- Cells are the basic building blocks of all living things. The human body is comprised of trillions of cells. They deliver structure for the body, take in nutrients from food, convert those nutrients into significance, and carry out technical functions.
- Cells are of two types: eukaryotic, which include a nucleus, and prokaryotic cells, which do not have a nucleus, but a nucleoid province is still present. Prokaryotes are single-celled organisms, while eukaryotes may be either single-celled or multicellular.
- They deliver structure for the body, take in nutrients from food, convert those nutrients into significance, and carry out technical functions. Cells also include the body's genetic material and can make duplicates of themselves. Cells have multiple parts, each with a separate function.

Answer:
Symbiosis is where no organism is killed in the relationship.
Parasitism: The host is harmed but not killed.
Mutualism: Both organisms are benefitted
Commensalism: One organism is benefitted, the other is not effected
In predation, the prey is killed and eaten by the predator for energy.
Sometimes you may see that they consider predation a symbiotic relationship, but not always.
Animals cannot make their own food, while plants can by photosynthesis
