The key difference between ascent of sap and translocation is that ascent of sap is the transportation of water and minerals from the root to aerial parts of the plant through the xylem, while translocation is the transportation of foods/carbohydrates from leaves to other parts of the plant through the phloem. Xylem and phloem are […]
Difference Between Exine and Intine
The key difference between exine and intine is that exine is the outer layer of a pollen grain containing sporopollenin, while intine is the inner layer of a pollen grain containing cellulose and pectin. Pollen is the actual male gametophyte of seed plants. It is a reduced form of the gametophyte. Also, pollen is a […]
Difference Between Vernalization and Stratification
The key difference between vernalization and stratification is that vernalization is a treatment that is used to promote flower initiation, while stratification is a treatment that is used to break seed dormancy. Vernalization and stratification are two important techniques associated with plants. Vernalization accelerates early flowering while stratification breaks seed dormancy. Thus, both types of […]
Difference Between Pedicel and Peduncle
The key difference between pedicel and peduncle is that pedicel is the stalk that holds an individual flower, while peduncle is the main stalk that holds a complete inflorescence. A flower is the main reproductive structure of flowering plants or angiosperms. There are several types of simple flowers, composite flowers and inflorescences. A simple flower […]
Difference Between Agamospermy and Apomixis
The key difference between agamospermy and apomixis is their occurrence. Agamospermy mainly occurs in gymnosperms, while apomixis mainly occurs in angiosperms. Plants reproduce asexually as well as sexually. Agamospermy and apomixis are two asexual modes of reproduction taking place in higher plants. They replace the process of formation of gametes. Moreover, during these processes, the […]
Difference Between Apospory and Apogamy
The key difference between apospory and apogamy is that in apospory, the gametophyte develops directly from the 2n sporophyte, while in apogamy, the embryo develops without undergoing fertilization. Apospory and apogamy are two types of asexual reproduction processes taking place in plants. Therefore, in both processes, the formation of gametes and syngamy do not take […]
Difference Between Taproot and Adventitious Root
The key difference between taproot and adventitious root is that tap root system, which has a thick deep primary root, is present in dicot plants, while adventitious root system, which has numerous small thin hair-like roots, is present in monocot plants such as grasses. Plants have two major systems as shoot system and root system. […]
Difference Between Turgor Pressure and Wall Pressure
The key difference between turgor pressure and wall pressure is that turgor pressure is the hydrostatic pressure developed against the cell wall due to endosmosis, while wall pressure is the pressure exerted by the cell wall against the turgor pressure. Endosmosis is the entering of water inside the cell. It occurs when the water potential […]
Difference Between Chlorosis and Necrosis
The key difference between chlorosis and necrosis is that chlorosis is yellowing of plant tissues as a result of decreased amounts of chlorophyll, while necrosis is the death of plant cells or tissues. Plants show different symptoms as a result of diseases, injuries or nutrient deficiencies. Some of the common symptoms include chlorosis, necrosis, wilting, […]
Difference Between Vein Clearing and Vein Banding
The key difference between vein clearing and vein banding is that vein clearing is a viral disease symptom in which veins become unnaturally clear or translucent, while vein banding is a viral disease symptom that appears as bands of lighter or darker colour along the main veins of a leaf. Plant viruses infect plants, causing […]
