What is the water?
Water (chemical formula: H2O) is a transparent fluid which forms the world's streams, lakes, oceans and rain, and is the major constituent of the fluids of organisms. As a chemical compound, a water molecule contains one oxygen and two hydrogen atoms that are connected by covalent bonds. Water is a liquid at standard ambient temperature and pressure, but it often co-exists on Earth with its solid state, ice; and gaseous state,steam (water vapor). It also exists as snow, fog, dew and cloud.

What is a human?
Modern humans (Homo sapiens, primarily ssp. Homo sapiens sapiens) are the only extant members of Hominina clade (or human clade), abranch of the taxonomical tribe Hominini belonging to the family of great apes. They are characterized by erect posture and bipedal locomotion;manual dexterity and increased tool use, compared to other animals; and a general trend toward larger, more complex brains and societies.
The spread of humans and their large and increasing population has had a profound impact on
large areas of the environment and millions of native species
worldwide. Advantages that explain this evolutionary success include a
relatively larger brain with a particularly well-developedneocortex, prefrontal cortex and temporal lobes, which enable high levels of abstract reasoning, language, problem solving, sociality, and culturethrough social learning. Humans use tools to a much higher degree than any other animal, are the only extant species known to build fires andcook their food, and are the only extant species to clothe themselves and create and use numerous other technologies and arts.
Humans are uniquely adept at utilizing systems of symbolic communication (such as language and art) for self-expression and the exchange of ideas, and for organizing themselves into purposeful groups. Humans create complex social structures composed of many cooperating and competing groups, from families and kinship networks to political states. Social interactions between humans have established an extremely wide variety of values, social norms, and rituals, which together form the basis of human society. Curiosity and the human desire to understand and influence the environment and to explain and manipulate phenomena (or events) has provided the foundation for developing science, philosophy,mythology, religion, anthropology, and numerous other fields of knowledge.
What is a plant?
Plants, also called green plants, are multicellular eukaryotes of the kingdom Plantae. They form an unranked clade Viridiplantae (Latin for green plants) that includes the flowering plants, conifers and other gymnosperms, ferns, clubmosses, hornworts, liverworts, mosses and thegreen algae. Green plants exclude the red and brown algae, the fungi, archaea, bacteria and animals.
What is love?
Love is a variety of different feelings, states, and attitudes that ranges from interpersonal affection ("I love my mother") to pleasure ("I loved that meal"). It can refer to an emotion of a strong attraction and personal attachment. It can also be a virtue representing human kindness,compassion, and affection—"the unselfish loyal and benevolent concern for the good of another".
