1. Smallest unit of classification is matched with Species.
In eukaryotic species: A group of living beings that can reproduce among themselves (inter-fertility) and whose offspring are fertile.
The species is the fundamental entity of classifications, which brings together living beings presenting a set of common morphological, anatomical, physiological, biochemical and genetic characteristics.
2. Segmented digestive system, appendages is matched with Animal characteristics.
If we take the example of mammals, the main element of the digestive system is a tube, open at both ends. One can distinguish: an upper pole, or cephalic, the oral cavity, true vestibule of the digestive tract, through which food enters; and a lower pole, or caudal, rectum, which controls defecation through the a-n-a-l orifice. Between these two poles, the digestive tract is divided into four segments: a passage region, represented by the pharynx, then the esophagus; a pocket, the stomach, where mechanical phenomena predominate; a long tube coiled into loops, the small intestine, where the main chemical transformations and the absorption of food take place; finally, a large, relatively short duct, the large intestine or colon, which dehydrates and digests the food residues, concentrates them in f-e-c-a-l matter.
3. Largest phylum of animals is matched with Arthropoda.
The arthropod branch is one of the most common at present (about half of the species described belong to this taxon).
The arthropod group contains insects, spiders, scorpions and centipedes, but also species belonging to fossil groups such as trilobites.
"arthropod" comes from arthron ("articulation") and podos ("foot"). It therefore refers to the fact that arthropods usually have segmented appendages.
4. Green, conductive tissue, seeds, flowers is matched with Plant characteristics.
Angiosperms are characterized by sexually seeded reproduction of gametes from flowers that eventually form a fruit, and conductive tissues: xylem and phloem.
The conductive tissues of the angiosperms are the xylem which drives the raw sap and the phloem which drives the elaborate sap.
5. Classification is matched with Taxonomy.
In biology, taxonomy is the science that describes and names living organisms and groups them into entities called taxa (families, genera, species ...) so that they can be named and classified. Taxonomy is also the science of the laws and rules that determine the establishment of methods and systems of classification, according to rules of systematic.
6. Groups of families is matched with Order.
In biology, order is the fourth level of classical classification of living species (see systematic).
The name of the orders ends with the suffix -ales in plants, algae and mushrooms.
For the animal kingdom, default suffixes are only set up below the rank of super-family.
In the taxonomy we can find super-orders, sub-orders, infra-orders and micro-orders.
7. Largest division of plants is matched with Tracheophyta.
A tracheophyte is a vascular plant of the Tracheophyta branch. Tracheophytes are chlorobionts with conducting vessels that are defined as terrestrial plants that have lignified tissues, xylem, for transporting water and minerals throughout the plant.
They also have a specialized non-lignified tissue, the phloem, to carry the products of photosynthesis. The xylem and phloem contain tracheids for the circulation of sap and vascularization, while a non-vascular plant is devoid of it, it is avascularized.
