Biological control or biocontrol is a method of controlling pests, whether pest animals such as insects and mites, weeds, or pathogens affecting animals or plants by using other organisms. [1] It relies on predation , parasitism , herbivory , or other natural mechanisms, but typically also involves an active human management role.
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 ...
Biopesticides usually have no known function in photosynthesis, growth or other basic aspects of plant physiology. Many chemical compounds produced by plants protect them from pests; they are called antifeedants. These materials are biodegradable and renewable, which can be economical for practical use.
Antagonism plays a critical role in agriculture, particularly in the development of biological control agent (BCAs) to manage phytopathogens and reduce reliance on synthetic pesticides. [16] Numerous microbial antagonists, including yeasts and bacteria , are isolated from diverse environments such as soil, plants, compost, and oceans for their ...
Water stress (drought and salt stress) is one of the major environmental problems causing severe losses in agriculture and in nature. Drought tolerance of plants is mediated by several mechanisms that work together, including stabilizing and protecting the plant from damage caused by desiccation and also controlling how much water plants lose through the stomatal pores during drought.
The exact components of a cell are determined by whether the cell is a eukaryote or prokaryote. [7] Nucleus (eukaryotic only): storage of genetic material; control center of the cell. Cytosol: component of the cytoplasm consisting of jelly-like fluid in which organelles are suspended within; Cell membrane (plasma membrane):
Only after Trump's hush-money sentencing can NJ officials move to revoke his liquor licenses. A revocation hearing is still pending, officials said.
Plant tissue culture is a collection of techniques used to maintain or grow plant cells, tissues, or organs under sterile conditions on a nutrient culture medium of known composition. It is widely used to produce clones of a plant in a method known as micropropagation .
