Answer: 5. Amoebocytes have a variety of functions: delivering nutrients from choanocytes to other cells within the sponge, giving rise to eggs for sexual reproduction (which remain in the mesohyl), delivering phagocytized sperm from choanocytes to eggs, and differentiating into more-specific cell types. 6. Sponges form symbiotic relationships with a variety of microorganisms, including bacteria and algae. A symbiotic relationship between organisms is a close ecological association between two species that may be mutually beneficial or may benefit one partner at the expense of the other. However, humans are still damaging sponge populations with weighted nets and even taut fishing lines, which can slice sponges apart by accident. As a rule, anything that can affect the ocean floor will have a negative impact on sponges, as they have never developed protection against impacts. brainliest??
