Plants are one of the most lush and rich groups of organisms in nature, widely distributed across the earth with diverse forms. In order to better study and utilize plant resources, scientists have scientifically classified plants. This article will unveil how plants are divided into families and introduce some common families and genera.
Plants are divided into several familiesThe plant kingdom is divided into multiple families based on similarities in morphology, structure, and genetic characteristics. Plant taxonomists generally believe that the plant kingdom is divided into about 30 phyla, with each phylum further divided into several classes, orders, families, genera, species, and other different taxonomic ranks. At the family level, plants are divided into about 350 families.
Related terms of plant families1. Family (Family): One of the basic units of plant classification, referring to a group of plants with similar morphology, structure, and genetic characteristics.
2. Genera (Genera): The classification unit under the family, referring to a group of plants with common characteristics.
3. Taxonomic relationship: Refers to the kinship between plants of different families and genera.
4. Phylum (Phylum): A higher classification unit of plant classification, between phyla and classes.
5. Distribution of genera: Refers to the distribution range of different plant families and genera on Earth.
Introduction to common plant families and genera1. Angiosperms (Angiosperms)
The Angiosperms are the largest phylum in the plant kingdom, including about 250 families. Here are some common Angiosperm families and genera:
(1) Asteraceae (Asteraceae): Such as chrysanthemum, sunflower, etc.
(2) Poaceae (Poaceae): Such as wheat, rice, corn, etc.
(3) Leguminosae (Leguminosae): Such as soybeans, mung beans, adzuki beans, etc.
(4) Rosaceae (Rosaceae): Such as apples, pears, peaches, etc.
2. Gymnosperms (Gymnosperms)
Gymnosperms include about 6 families. Here are some common Gymnosperm families and genera:
(1) Pinaceae (Pinaceae): Such as pine trees, spruce, etc.
(2) Cupressaceae (Cupressaceae): Such as cypress, cedar, etc.
(3) Ginkgoaceae (Ginkgoaceae): Such as ginkgo trees.
3. Pteridophytes (Pteridophytes)
The Pteridophytes include about 11 families. Here are some common Pteridophyte families and genera:
(1) Dryopteridaceae (Dryopteridaceae): Such as wire grass, cyrtomium, etc.
(2) Polypodiaceae (Polypodiaceae): Such as water dragon bone, stone sweet, etc.
(3) Pteridaceae (Pteridaceae): Such as bracken, wire grass, etc.
Plants are divided into about 350 families, with each family further divided into several genera. Understanding plant classification helps us better study and utilize plant resources. This article has introduced how plants are divided into families and some common families and genera, hoping to be helpful to you.
