Capsule
Explanation:
In many bacterial species, an extracellular layer composed of a polysaccharide especially a monosaccharide is produced around the cell wall of the bacteria. This extracellular layer is known as the slime layer or the capsule.
The capsule in bacteria serves many purposes like it protects the bacteria from the destruction by the white blood cell in the host, it enables the bacteria to adhere to the substrates and protect it.
In the plant group called the bryophytes also a capsule structure is present which grows in the sporophytic phase and encloses the spores, therefore, the capsule is considered the sporangium of the bryophytes.
Thus, the capsule is correct.
Answer:
organizational effect.
Explanation:
Organizational effect is a long-term effect of hormonal action typically occurring in fetal development or the early postnatal period that leads to permanent changes in behavior and neural functioning. For example, the presence of testosterone in young male rats leads to long-term male-typical behavior, and female rats can be masculinized by neonatal exposure to testosterone.
Organizational effects act during development, often during critical period. Such hormones affect the construction or fine-tuning of sex organs or neural circuits underlying behavioral capacities that will be needed in adulthood.
Organizational effects are often under tight genetic control, and not subject to major influence by environment.
Organizational effects are often irreversible.
Stem cell are important because stem cells represent an exciting area in medicine because of their potential to regenerate and repair damage tissue .
