photosynthetic aquatic plants
B
unicellular protists with flagella
C

D

Verified step by step guidance1
Understand the classification of sponges: Sponges belong to the phylum Porifera and are considered simple multicellular animals. They are not plants, protists, or complex animals with specialized organs.
Clarify the absence of true tissues: Sponges lack true tissues, which are groups of cells organized to perform specific functions. Instead, they have loosely organized cells that perform basic functions.
Examine the structure of sponges: Sponges have a porous body structure and rely on water flow through their pores for feeding, respiration, and waste removal. They do not have specialized organs.
Differentiate sponges from other organisms: Sponges are distinct from photosynthetic plants, unicellular protists, and complex animals due to their simple multicellular structure and lack of true tissues.
Conclude the correct description: Based on their characteristics, sponges are best described as simple, multicellular animals lacking true tissues.
