This is the list of Schedule II controlled substances in the United States as defined by the Controlled Substances Act. [ 1] The following findings are required for substances to be placed in this schedule: [ 2] The drug or other substance has a high potential for abuse. The drug or other substance has a currently accepted medical use in ...
Flowering Plant. Secondary metabolism produces a large number of specialized compounds (estimated 200,000) that do not aid in the growth and development of plants but are required for the plant to survive in its environment. Secondary metabolism is connected to primary metabolism by using building blocks and biosynthetic enzymes derived from ...
Plants are capable of producing and synthesizing diverse groups of organic compounds and are divided into two major groups: primary and secondary metabolites. [9] Secondary metabolites are metabolic intermediates or products which are not essential to growth and life of the producing plants but rather required for interaction of plants with their environment and produced in response to stress.
Plants that produce toxins and/or cause irritation on contact are referred to as poisonous plants. [1] The toxins in poisonous plants affect herbivores , and deter them from consuming the plants. Plants cannot move to escape their predators, so they must have other means of protecting themselves from herbivorous animals.
Definition. 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.
Oxygen is produced by plants and some bacteria in photosynthesis, while CO 2 is a waste product of all animals and plants. Nitrogen gases are produced by denitrifying bacteria and as a waste product, and bacteria for decaying yield ammonia, as do most invertebrates and vertebrates. Water is the only liquid waste from animals and ...
Mucilage is a thick gluey substance produced by nearly all plants and some microorganisms. These microorganisms include protists which use it for their locomotion. The direction of their movement is always opposite to that of the secretion of mucilage. [ 1] It is a polar glycoprotein and an exopolysaccharide.
Phytotoxin. Phytotoxins are substances that are poisonous or toxic to the growth of plants. Phytotoxic substances may result from human activity, as with herbicides, or they may be produced by plants, by microorganisms, or by naturally occurring chemical reactions. The term is also used to describe toxic chemicals produced by plants themselves ...
