Right

Wrong

You need to know the structure of flatworms.

Structure

The body is bilaterally symmetrical, with clearly defined head and caudal ends, somewhat flattened in the dorsoventral direction, in large representatives it is strongly flattened. The body cavity is not developed (except for some phases of the life cycle of tapeworms and flukes). Gases are exchanged across the entire surface of the body; respiratory organs and blood vessels are absent.

Coverings of the body

The outside of the body is covered with single-layer epithelium. In ciliated worms, or turbellarians, the epithelium consists of cells bearing cilia. Flukes, monogeneans, cestodes and tapeworms lack ciliated epithelium for most of their lives (although ciliated cells can be found in larval forms); their integument is represented by the so-called tegument, in a number of groups bearing microvilli or chitinous hooks. Flatworms with tegument belong to the group Neodermata. Flatworms can regenerate 6/7 of their body.

Musculature

Under the epithelium there is a muscular sac, consisting of several layers of muscle cells that are not differentiated into individual muscles (certain differentiation is observed only in the area of ​​the pharynx and genital organs). The cells of the outer muscle layer are oriented transversely, while the cells of the inner layer are oriented along the anterior-posterior axis of the body. The outer layer is called the circular muscle layer, and the inner layer is called the longitudinal muscle layer.

Throat and gut

In all groups, except cestodes and tapeworms, there is a pharynx leading to the gut or, as in the so-called intestinal turbellarians, to the digestive parenchyma. The intestine is blindly closed and communicates with environment only through the mouth. Several large turbellarians have been noted to have anal pores (sometimes several), but this is the exception rather than the rule. In small forms the intestine is straight, in large ones (planaria, flukes) it can be highly branched. The pharynx is located on the abdominal surface, often in the middle or closer to the posterior end of the body, in some groups it is shifted forward. Cestode-shaped and tapeworms do not have a gut.

Nervous system and sensory organs

The nervous system is represented by nerve ganglia located in the front part of the worm’s body, cerebral ganglia and nerve columns extending from them, connected by jumpers. The sense organs are usually represented by individual skin cilia - processes of sensory nerve cells. Some free-living representatives of the type, in the process of adaptation to living conditions, acquired light-sensitive pigmented eyes - primitive organs of vision and organs of balance.

Nephridia and accumulation buds

Osmoregulation is carried out with the help of protonephridia - branching channels connecting into one or two excretory channels. The release of toxic metabolic products occurs either with fluid excreted through protonephridia, or through accumulation in specialized parenchyma cells (atrocytes), which play the role of “storage buds”.

Each question has four possible answers. It is necessary to select only one correct one and enter it into the matrix.
