The key difference between prop root and stilt root is that prop root is an adventitious root developed from horizontally spread branches of the tree while stilt root is a type of adventitious root developed from basal nodes of the stem near the soil. Plants have a root system in order to anchor into the […]
Difference Between Symplast and Vacuolar Pathway
The key difference between symplast and vacuolar pathway is that in the symplast pathway, water does not enter into vacuoles while in the vacuolar pathway, water passes into vacuoles. Water moves through plant cells, especially across the root, via three major pathways. They are apoplast, symplast and vacuolar pathways. In the apoplast pathway, water and […]
Difference Between Plastoquinone and Plastocyanin
The key difference between plastoquinone and plastocyanin is that plastoquinone is a lipophilic carrier molecule that transfers electrons to plastocyanin through cytochrome b6f protein complex. But, plastocyanin is a small water-soluble blue-copper protein that accepts a pair of electrons from the cytochrome b6f complex and passes it to photosystem I in the thylakoid space. Photosynthesis […]
Difference Between Mesophyll and Bundle Sheath Cells
The key difference between mesophyll and bundle sheath cells is that in C4 plants, light-dependent reactions of photosynthesis take place in the mesophyll cells, while light-independent reactions or Calvin cycle take place in the bundle sheath cells. C4 plants are a group of plants that carry out C4 photosynthesis or C4 carbon fixation. These plants […]
Difference Between Palisade Parenchyma and Spongy Parenchyma
The key difference between palisade parenchyma and spongy parenchyma is that palisade parenchyma consists of columnar cells which are compacted tightly below the upper epidermis of a leaf while spongy parenchyma consists of rounded cells which are loosely arranged below the palisade parenchyma. Leaves are the main structural parts of plants that produce food by […]
Difference Between Pericycle and Endodermis
The key difference between pericycle and endodermis is that pericycle is a cylinder of parenchyma or sclerenchyma cells that surround the ring of vascular bundles in the stele, while endodermis is the cylinder of cells that separate the cortex from the stele. Pericycle and endodermis are two types of cell cylinders seen in plant roots. […]
Difference Between Anatropous and Orthotropous Ovule
The key difference between anatropous and orthotropous ovule is that anatropous is the most common ovule orientation in angiosperms in which the ovule is completely inverted in 180o so that the micropyle and hilum come closer to each other. Meanwhile, orthotropous is an ovule orientation in which the micropyle lies directly in line with the […]
Difference Between Quiescence and Dormancy
The key difference between quiescence and dormancy is that quiescence is the inability of a normal, non-dormant seed to germinate because of the absence of conditions suitable for germination while dormancy is an evolutionary adaptation that prevents seeds from germinating during unsuitable ecological conditions that would typically lead to a low probability of seedling survival. Quiescence and […]
Difference Between Stratification and Scarification
The key difference between stratification and scarification is that stratification is the mechanism in which seeds experience a period of moist and cold conditions to induce germination. Meanwhile, scarification is the mechanism in which seed germination is induced by breaking the seed coat. Seeds develop into plants via a process called seed germination. To germinate, […]
Difference Between Stipule and Axillary Bud
The key difference between stipule and axillary bud is that the stipule is one of the two leaf-like appendages present at the base of the leaf. Meanwhile, the axillary bud is the bud or the little protuberance present in between the angle formed by the stem and the leaf petiole. Roots, stems, and leaves are […]
