Certain organisms lack a specialized transport system for moving nutrients around the body. These organisms generally lack advanced circulatory systems.
A haemal system is a network of vessels found in certain invertebrates that functions in circulation. It helps transport nutrients, gases, and waste products throughout the organism's body.
An example of a eukaryotic organism that lacks complex organ systems is a protist like an amoeba. Protists are single-celled organisms that do not have specialized tissues or organs like multicellular organisms. Instead, they rely on various organelles within their cell to carry out essential functions.

A brainless organism is an organism that lacks a central nervous system or a defined brain. These organisms may have simpler nerve networks or rely on decentralized nerve cells to coordinate their bodily functions. Examples include jellyfish and sponges.
A brainless organism is an organism that lacks a centralized organ for coordinating its actions and responding to stimuli, such as plants, fungi, or single-celled organisms like bacteria or amoebas. These organisms rely on decentralized systems or specialized structures to carry out life processes.

No, Platyhelminthes lacks a circulatory system and a respiratory system.

It lacks a backbone.
An organless organism is an organism that lacks specialized organs for specific functions, such as digestion, respiration, or circulation. These organisms rely on simpler structures or processes to carry out essential functions. Examples include single-celled organisms like bacteria or protists.
An organism that's lacks a nuclear membrane. It doesn't have a true nucleus.
