As soon as Zechariah had written on a writing table: "His name is John", he regained the power of speech, and blessed "the Lord God of Israel" with a prophecy known as the Benedictus or "Song of Zechariah" (Luke 1:57–79). Domenico Ghirlandaio's fresco Zechariah Writes Down the Name of His Son (1490, fresco in the Tornabuoni Chapel, Florence)
Plant cells differentiate into multiple cell types, forming tissues such as the vascular tissue with specialized xylem and phloem of leaf veins and stems, and organs with different physiological functions such as roots to absorb water and minerals, stems for support and to transport water and synthesized molecules, leaves for photosynthesis ...
Structure of a plant cell. Plant cells are the cells present in green plants, photosynthetic eukaryotes of the kingdom Plantae.Their distinctive features include primary cell walls containing cellulose, hemicelluloses and pectin, the presence of plastids with the capability to perform photosynthesis and store starch, a large vacuole that regulates turgor pressure, the absence of flagella or ...
Tropisms are usually named for the stimulus involved; for example, a phototropism is a movement to the light source, and an anemotropism is the response and adaptation of plants to the wind. [2] Tropisms occur in three sequential steps. First, there is a sensation to a stimulus. Next, signal transduction occurs. And finally, the directional ...
A typical plant cell may have between 1,000 and 100,000 plasmodesmata connecting it with adjacent cells [11] equating to between 1 and 10 per μm 2. [ 12 ] [ failed verification ] Plasmodesmata are approximately 50–60 nm in diameter at the midpoint and are constructed of three main layers, the plasma membrane , the cytoplasmic sleeve , and ...

MLB will install a natural grass field for the Athletics in West Sacramento in an effort to keep temperatures down during ballgames.
In the process of plant roots growing in the direction of gravity by gravitropism, high concentrations of auxin move towards the cells on the bottom side of the root. This suppresses growth on this side, while allowing cell elongation on the top of the root. As a consequence of this, curved growth occurs and the root is directed downwards. [3]
