The key difference between algae and protozoa is that algae are autotrophic plant-like eukaryotes while protozoa are heterotrophic animal-like eukaryotes that belong to kingdom Protista. There are five major kingdoms that classify all living organisms based on 3 criteria: cellular organization, arrangement of cells, and type of nutrition. They are Kingdom Monera, Protista, Fungi, Plantae […]
Difference Between Collenchyma and Sclerenchyma
The key difference between collenchyma and sclerenchyma is that collenchyma is a type of live plant cell that has irregularly thickened primary cell walls while sclerenchyma is a type of dead plant cell that has heavily thickened secondary walls. There are three types of ground tissues in plants. They are parenchyma, collenchyma, and sclerenchyma. Parenchyma […]
Difference Between Spore and Endospore
Spore vs Endospore Spore Depending on the different types of spores a plant can be homosporous or heterosporous. If the plant has only one type of spores, it is known as homospory. If the plant has two types of spores, male and female spores, it is known as heterospory. Male spores are called microspores […]
Difference Between Photosynthesis and Chemosynthesis
The key difference between photosynthesis and chemosynthesis is that the photosynthesis is the process of converting the energy of sunlight into carbohydrates by photoautotrophs while chemosynthesis is the process of converting the chemical energy of inorganic compounds or methane into organic compounds by chemoautotrophs. Photosynthesis and chemosynthesis are two important processes that allow living organisms […]
Difference Between Stem and Root
Stem vs Root Stem In the primary structure of the dicot stem, the outermost layer is the epidermis. This is normally a single layer. Above the epidermis is the cuticle. Multicellular epidermal hairs and stomata are present in the epidermis. Below the epidermis is the cortex. It is relatively narrow and is differentiated into […]
Difference Between Dispersion and Diffusion
Dispersion vs Diffusion Dispersion and diffusion are two topics discussed in physics and other related fields. Dispersion is a process discussed in physics under waves and optics as well as under material properties. Diffusion is a process discussed in material properties. Both of these phenomena are very important in the understanding of fields such […]
Difference Between dB and dBm
dB vs dBm dB and dBm are units related to measurements in sound and acoustics. The notations dB and dBm are used to represent decibel and the ratio between the decibel level and a standard decibel level of 1 milliwatt. The unit decibel is used to measure the sound intensity level of a wave. […]
Difference Between Magnetic Force and Electric Force
Magnetic Force vs Electric Force Magnetic forces and electric forces are two forces that occur in nature. Electric forces are the forces that occur due to electric charges whereas magnetic forces are the forces that occur due to magnetic dipoles. Electric forces and magnetic forces combine to give the electromagnetic force, which is one […]
Difference Between Frequency and Relative Frequency
Frequency vs Relative Frequency Frequency and relative frequency are two concepts that are discussed in physics and related subjects. Frequency is the number of occurrences per unit type. Relative frequency is the frequency of an event with respect to another. Both of these concepts are fairly important in the understanding of waves and vibrations […]
Difference Between Mirror and Lens
Mirror vs Lens Lens and mirror are two different devices which are used in optics. A mirror is a device that is based on the principle of reflection whereas lenses are devices that are based on the principle of refraction. Both of these devices are very important in fields such as optics, astronomy, photography […]
