b. pseudocoelom
Explanation:
A pseudocoelom is a false body cavity of some invertebrates which occupies the space localized between the mesoderm and the endoderm of the gut. This false cavity is found in nematodes.
Arthropods exhibit:
1- Bilateral symmetry because both opposite sides of the body are similar,
2- they are protostomes because the blastopore becomes the mouth during embryonic development,
3- they have true tissues because tissues are formed by groups of cells which share a common function, and finally,
4-arthropods are triploblastic because they are formed by three germ embryonic layers (endoderm, mesoderm and ectoderm).
Answer:
The correct answer is multicellular organisms.
Explanation:
Organs are differentiated structure formed by group of cells and tissues to perform the similar functions. When more than two organs perform specific function in a coordinated manner they form organ system.
Tissues and organs are a characteristic feature of multicellular organisms as more than one cell is present in these organisms and these cells aggregate together to form tissues, which further aggregate to form different organs carrying out the different functions attaining complexity.
Since, unicellular organisms do not have more than one cell, unicellular cells do not form tissues and lack organs.
Thus, the correct answer is multicellular organisms.
which is absent in unicellular organisms.
