Each worker is given a number of mecates to plant daily. He makes a series of holes, very shallow, in the burned soil about 8 feet (2.4 m) apart in each direction, and places a bud or cutting of a henequen plant in each hole. Each mecate can support 80 to 100 plants. The holes are typically made with a digging stick with a sharp iron point, and ...
A sundew with a leaf bent around a fly trapped by mucilage. Mucilage is a thick gluey substance produced by nearly all plants and some microorganisms.These microorganisms include protists which use it for their locomotion, with the direction of their movement always opposite to that of the secretion of mucilage.

Phytochemicals are chemicals of plant origin. [1] Phytochemicals (from Greek phyto, meaning "plant") are chemicals produced by plants through primary or secondary metabolism. [2] [3] They generally have biological activity in the plant host and play a role in plant growth or defense against competitors, pathogens, or predators. [2]
Cassava is a tuberous edible plant that was likely first cultivated by the Maya people in Yucatán in present-day Mexico. The plant is the source of flour, bread, tapioca, and an alcoholic beverage.
Juglone is an example of such a molecule inhibiting the growth of other plant species around walnut trees. [citation needed] The aquatic vascular plant Myriophyllum spicatum produces ellagic, gallic and pyrogallic acids and (+)-catechin, allelopathic phenolic compounds inhibiting the growth of blue-green alga Microcystis aeruginosa.

All land plants and green algae possess two forms of this pigment: chlorophyll a and chlorophyll b. Kelps, diatoms, and other photosynthetic heterokonts contain chlorophyll c instead of b, while red algae possess only chlorophyll a. All chlorophylls serve as the primary means plants use to intercept light in order to fuel photosynthesis.
Strigolactones play a fundamental role in plant-fungi interaction. [25] One of the first studies made in Lotus japonicus had already demonstrated that compounds extracted from the root were necessary for the development of arbuscular mycorrhizal fungi that will establish a symbiotic relationship with the plant's root.

Naturally dyed skeins made with madder root, Colonial Williamsburg, VA. Natural dyes are dyes or colorants derived from plants, invertebrates, or minerals.The majority of natural dyes are vegetable dyes from plant sources—roots, berries, bark, leaves, and wood—and other biological sources such as fungi.
