Question

Symbiodiniaceae and other microbes perform chemotaxis to move towards chemical attractants and away from chemical repellants.

Options:
a) Chemotaxis is not a significant factor in microbial movement.
b) Symbiodiniaceae always move away from chemical attractants.
c) Microbes, including Symbiodiniaceae, exhibit chemotaxis.
d) Symbiodiniaceae move randomly in response to chemicals.

Answer 1

Chemotaxis is the significant behavior employed by microbes, including Symbiodiniaceae, to move towards chemical attractants or away from repellants, facilitating their survival and adaptation.

Step-by-step explanation:

Microbes, including Symbiodiniaceae, exhibit chemotaxis: the directional movement of a cell in response to a chemical attractant or repellant. Chemotaxis is a significant behavior in microbial movement, allowing organisms such as bacteria to move toward nutrient sources or away from harmful substances. Positive chemotaxis involves moving towards increasing concentrations of a chemical attractant, while negative chemotaxis entails moving away from a repellant. This process is crucial for the survival of microbes, enabling them to navigate and adapt to their environment effectively.
