Organism represented by a single cell:

A single-celled organism is an organism that consists of only one cell. It carries out all the necessary functions of life within that single cell. Here are the examples you provided:

1) White Planarian: The white planarian, also known as Dugesia japonica, is a type of flatworm that belongs to the phylum Platyhelminthes. It is a free-living organism found in freshwater environments. The white planarian is capable of regenerating its body parts, including its head and tail, making it a fascinating organism for studying regeneration [[1]].

2) Common Amoeba: The common amoeba, also known as Amoeba proteus, is a type of protozoan that belongs to the phylum Amoebozoa. Amoebas are known for their ability to constantly change their shape by extending and retracting pseudopods. They are found in freshwater environments and feed on bacteria and other small organisms [[2]].

3) Malaria Parasite: The malaria parasite, known as Plasmodium, is a single-celled organism that causes malaria in humans. It belongs to the phylum Apicomplexa. Malaria is a life-threatening disease transmitted through the bite of infected mosquitoes. The parasite undergoes complex life cycles involving both humans and mosquitoes [[3]].

4) Cross Spider: The cross spider, also known as Araneus diadematus, is a type of spider that belongs to the class Arachnida. While spiders are typically multicellular organisms, they are made up of many cells that work together to form a complete organism. Cross spiders are known for their distinctive cross-shaped markings on their abdomens and their intricate orb-shaped webs [[4]].

Organs of vertebrate animals:

Vertebrate animals, including mammals, birds, reptiles, amphibians, and fish, have specialized organs that perform specific functions. Here are the organs you mentioned:

1) Heart: The heart is a vital organ that pumps blood throughout the body. It is responsible for supplying oxygen and nutrients to the tissues and organs and removing waste products. The heart consists of four chambers: two atria and two ventricles. It is part of the circulatory system and plays a crucial role in maintaining homeostasis [[5]].

2) Epidermis: The epidermis is the outermost layer of the skin in vertebrate animals. It acts as a protective barrier against pathogens, UV radiation, and water loss. The epidermis also contains specialized cells called melanocytes, which produce the pigment melanin responsible for skin color [[6]].

3) Hair: Hair is a characteristic feature of mammals. It grows from hair follicles embedded in the dermis, the layer of skin beneath the epidermis. Hair serves various functions, including insulation, protection, sensory perception, and communication [[7]].

4) Hooves: Hooves are specialized structures found in some mammals, such as horses, cows, and deer. They are made of keratin and provide support and protection to the animal's feet. Hooves are adapted for different locomotion strategies, such as running, jumping, or climbing, depending on the species [[8]].
