Echeveria Pallida Plant Info: Growing Argentine Echeveria Succulents
Growing Echeveria Pallida Succulents
The plant name “e” means “in” or “around”. So, it’s not surprising that the Latin word for “plant”, pallidum, comes from the same root.
The Spanish word for “plants”, pájaro, was borrowed into English during the 1600s. The word “succulent” came from the French term sucré, which meant “to make sweet.” The Latin suffix -ium, meaning “of,” became “-is” when it entered English.
In the early 1800s, a German named Johann Jacobi (1744-1809) published a book called On Plants. His work contained over 500 plants and their cultivation techniques.
Later, in 1873, another German named Carl Linnaeus (1707-1778) published his Systema Naturae. He divided all living things into four kingdoms: animal, vegetable, fungi and mineral. Plants were placed under the kingdom kingdom Animalia.
In 1872 a British botanist named William Buckland (1843-1922) published his book Flora Britannica. He included over 1,000 species of plants in England and Wales.
The Columbia Encyclopedia (Sixth Edition) states that the first plant bloomed about 550 million years ago. This plant is called Cooksonia, and it was a single-celled organism.
Later, about 1,000 million years ago, plants with differentiated cells began to appear. The first plant with specialized parts was a moss-like organism called Prototaxites. It appeared about 850 million years ago.
Most plants fall under the kingdom Plantae. Some plants, such as green algae and blue-green bacteria, fall under the kingdom Monera.
All plants are made up of cells. They do not move unless they are capable of “independent” movement (for example, through the dispersal of seeds or spores).
The growth patterns of some plants are quite complex. The shape of a leaf, for example, is influenced by interaction between an organism’s hormones and other factors.
This complex process is called differentiation.
In the 1600s a German scientist named Julius von Sachs (1832-1897) developed an evolutionary theory that combined Charles Darwin’s (1809-1882) theory of evolution with Gregor Mendel’s (1822-1884) principles of genetics.
In 1797 an Italian called Alessandro Volta (1745-1827) invented the electrical cell. This was the beginning of the field of electronics and our modern technology.
An important writer in the field of plants was a German named Carl Friedrich von Gärtner (1772-1850). In 1805 he wrote On the Effects of the Air and Soil in Our Gardens and Greenhouses, an important work on horticulture.
The word “in vitro” is Latin for “in glass.” Asexual reproduction in plants is called vegetative reproduction and may take place through budding, division, layering or stem cutting.
The plant with the largest genome size is probably the bamboo (Bambusa vulgaris), with about half a million genes. The smallest genome size is found in plants such as yeast and mustard plants, with only thirteen thousand genes.
The first green plant was probably a red alga. Red algae are among our oldest ancestors, and they appeared about 1,200 million years ago.
Green plants appeared about 500 million years ago.
