Plants that have similar flowers, reproductive structures, other characteristics, and are evolutionarily related, are grouped into plant families (See Figure 2). Species in the same plant family tend to have similar growth characteristics, nutrient needs, and often the same pests (pathogens, herbivores).
Therefore, plant families are determined by flowers and reproductive parts. The patterns created by petals, sepals, stamens and pistils determine the plant family and the individual species.
Family (Latin: familia, plural familiae) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus.
Animal families end with the suffix ' idae' and plant families end in the suffix ' aceae'.
Kingdom Plantae is broadly composed of four evolutionarily related groups: bryophytes (mosses), (seedless vascular plants), gymnosperms (cone bearing seed plants), and angiosperms (flowering seed plants).
Living things are divided into five kingdoms: animal, plant, fungi, protist and monera.
The lycopods or lycophytes are one of the oldest lineages of living vascular plants. They first appeared in the Silurian period (425 million years ago), and became extremely diverse by the late Carboniferous period (323-298 million years ago) and some species grew as trees more than 100 feet tall.
Asteraceae (daisy family)
This the largest plant family on earth, with more than 1,620 genera and 23,600 species, including daisy, sunflower, lettuce, dandelion, artichoke, as well as many favourite garden ornamentals such as chrysanthemums, cosmos, dahlias, marigolds and zinnias.
The three largest flowering plant families containing the greatest number of species are the sunflower family (Asteraceae) with about 24,000 species, the orchid family (Orchidaceae) with about 20,000 species, and the legume or pea family (Fabaceae) with 18,000 species.
Proteaceae. The Proteaceae family of flowering plants, including banksias, grevilleas and waratahs, are among Australia's most popular natives. A key characteristic of the Proteaceae family is that flower heads are made up of a number of small flowers.
A genus is a class or group of something. In biology, it's a taxonomic group covering more than one species. This is a term used by biologists to classify more than one species under a larger umbrella. In biology, the word family describes the broadest group category, then genus, and then species.
A botanical name is a formal scientific name conforming to the International Code of Nomenclature for algae, fungi, and plants (ICN) and, if it concerns a plant cultigen, the additional cultivar or Group epithets must conform to the International Code of Nomenclature for Cultivated Plants (ICNCP).
Sexual reproduction requires genetic material ( DNA ) from two parents. The parent plants have male and female sex cells, called gametes. The genetic material from the male and female gametes combines to produce offspring.
Genus and Family
Thus, a family would usually be more inclusive and consists of a greater number of organisms. The genera of a particular family evolve from the same ancestors for having relatively common characteristics. In the taxonomic rank, a family is above the genus level and below the order.
Acacia (Leguminosae, Caesalpinioideae, mimosoid clade) is the largest and most widespread genus of plants in the Australian flora, occupying and dominating a diverse range of environments, with an equally diverse range of forms.
The family with the most species is the Poaceae which includes a huge variety of species, from the tropical bamboo Bambusa arnhemica to the ubiquitous spinifex that thrives in arid Australia from the genus Triodia.
So the correct option is " Compositae".
Lowly liverworts have been generally considered the most primitive of existing plants.
Angiosperms are also the youngest of the plant divisions, having arisen relatively late in the history of terrestrial plant life.
The Great Basin Bristlecone Pine (Pinus longaeva) is a species of pine tree. It is found in the Western United States, mostly in Utah, Nevada, and California. One of these trees has been measured to be 5,065 years old! That makes it the longest living non-clonal organism found on Earth.
Algae are broadly classified as micro- and macroalgae based on size. Macroalgae indicates large aquatic photosynthetic plants that can be seen without the aid of a microscope and can generally be divided into three groups: Green (Chlorophyta), Red (Rhodophyta), and Brown-Kelps (Phaeophyta—related to Chromista).
The kingdom Fungi is a large and diverse group of organisms, estimated to comprise between 1.5 and 7.1 million species (Dornburg et al., 2017). The group ranges from unicellular yeasts to multicellular filamentous fungi that also include macroscopic fungi that form large fruiting bodies (Boland et al., 2012).
The Animal Kingdom contains these seven Phyla: Porifera, Cnidaria, Platyhelminthes, Annelida, Mollusca, Arthropoda, and Chordata. The bodies of animals are made up of differentiated tissues to perform an equally specialized task, sometimes in to or three levels of differentiation (excluding sponges).
