Which of the Following is Not a Modular Organism

Question

Which of the following is not a modular organism?
A) Creosote bush
B) Streptococcus bacteria
C) Quercus spp. oak tree
D) Baetis spp. mayfly

Accepted Answer

Modular organisms are characterized by the repetition of similar units (modules) in their structure, allowing them to grow and reproduce in a flexible manner. Creosote bushes, Streptococcus bacteria, and Quercus spp. oak trees all exhibit modular growth patterns through the repetition of structures such as branches, bacterial cells, or leaves. In contrast, Baetis spp. mayflies, like other insects, have a determinate growth pattern with a fixed body plan that does not exhibit modularity in the same way, making them non-modular organisms.
