Mycorrhizae have a symbiotic relationship with the roots of higher plants. These mutualistic associations benefit both parties, with fungi aiding in nutrient uptake for the plant while receiving organic compounds in return. This symbiosis enhances plant growth, stress tolerance, and ...

All fungi are always heterotrophs. They rely on external sources of organic carbon to obtain energy for growth and metabolism. Unlike autotrophs, which can produce their own organic compounds through photosynthesis, fungi must consume preformed organic matter as nutrients from ...
TMV is related to viruses. TMV stands for Tobacco Mosaic Virus, one of the first discovered viruses. It infects tobacco plants and other crops, causing mosaic-like patterns on leaves and stunting growth. TMV’s discovery helped advance the study of virology.
Viruses do not contain enzymes. Unlike other living organisms such as algae, lichen, and bacteria, viruses lack cellular machinery and cannot carry out metabolic processes on their own. They rely on host cells for replication and metabolism.
Viruses are considered to be a transitional group between living and non-living. They exhibit properties of life, such as replication, only when inside a host cell, but are inert and lack cellular structure outside of a host.
