The answer choices should be given for someone to know which would describe what septa are. Not having this information makes it hard to k know which is the right answer.
No, septa of hyphal cross walls are not always present in fungi. Some fungi have continuous hyphae without septa, known as coenocytic fungi, while others have septa that divide the hyphae into compartments.
Hyphae are divided by septa, which are partition-like structures that separate the cytoplasm in fungal cells. Some fungi have septate hyphae, where each cell is divided by septa, while others have nonseptate hyphae, where the cytoplasm is continuous along the hyphae.

Septa are internal structures found in certain fungi, particularly in their hyphae, which help compartmentalize the fungal cells and allow for the efficient transport of nutrients and communication between cells. In contrast, plant cell walls are primarily composed of cellulose and serve to provide structural support, protection, and shape to the plant cells. While septa are thin and can be perforated to facilitate movement, plant cell walls are typically thicker and more rigid, contributing to the overall strength and integrity of the plant. Additionally, septa can vary in structure and composition depending on the type of fungus, whereas plant cell walls have a more consistent composition across species.
In annelids, the group known as clitellates, which includes earthworms and leeches, has lost the septa between coelomic compartments. This loss allows for a more integrated and flexible body plan, facilitating movement and the efficient use of body space for various functions, such as reproduction and locomotion. The absence of these septa contrasts with other annelid groups, such as polychaetes, which retain distinct septa between their coelomic segments.
The segments of an annelid are called "metameres" or "somites." Annelids, such as earthworms and leeches, have a body that is divided into these repeating segments, which are separated by internal and external septa. This segmentation allows for greater flexibility and mobility, as well as the specialization of certain segments for specific functions.
The partitions that separate the segments of the annelid body are known as septa (singular: septum). These thin walls of tissue divide the coelomic cavity, providing structural support and compartmentalization for the organs within each segment. This segmentation allows for greater flexibility and movement, as well as more efficient locomotion and organ function. Additionally, the presence of septa aids in the independent control of muscle contractions in each segment.
There is no such number as septa nor septa zero.

Septa can have several different meanings. Septa can represent a prefix meaning "seven". Septa is also an acronym for the Southeastern Pennsylvania Transportation Authority.
SEPTA was created in 1965.
