Chlorophyll vs Chloroplast Photosynthesis is the light driven reaction that converts carbon dioxide and water in to energy rich sugars. Photosynthesis is initiated by the capture of light energy by chlorophyll pigments. Chloroplast is the site where photosynthesis takes place. Chloroplast Chloroplast is a plastid type organelle. These are found in plant cells and […]
Difference Between Cyanobacteria and Algae
The key difference between cyanobacteria and algae is that cyanobacteria are a group of prokaryotic bacteria while algae are small eukaryotic plant-like organisms. Photosynthesis is an extremely important process that converts the energy of sunlight into chemical energy of carbohydrates. Hence, it is the process that allows certain organisms to make their own foods, and […]
Difference Between Fruit and Seed
The key difference between fruit and seed is that fruit is the developed ovary of angiosperms after fertilization while seed is a fertilized ovule of plants. Pollination is the process of transferring pollen from anthers to the stigma of the flowers. And, it can be self-pollination or cross-pollination. Once pollens land on the stigma, they […]
Difference Between Fertile and Ovulation
The key difference between fertile and ovulation is that the fertile is the time period where both the egg and the sperms are viable within the female reproductive system while the ovulation is the process of releasing an egg by an ovary. The two terms, fertile and ovulation are used in the context of conception […]
Difference Between Vacuoles and Vesicles
The key difference between vacuoles and vesicles is that the vacuoles are large membrane-bound sacs used as storage while the vesicles are small membrane-bound sacs used as storage and to transport inside the eukaryotic cells. A cell is like a bag of chemicals, which is capable of survival and self-replication. The cell membrane separates the […]
Difference Between Pollen and Spore
Pollen vs Spore Diploid spore mother cells give rise to spores. Spores are haploid structures. They are important for reproduction as well as for survival in the unfavorable conditions. Spores are seen as a part of the life cycle of many organisms including plants, fungi, bacteria, algae etc. In plants, depending on the different […]
Difference Between Pollen and Nectar
Pollen vs Nectar Flower is a highly specialized reproductive shoot. A typical flower has 4 whorls, one after the other, on a stalk. The stalk can be short or long. The two lower whorls are not directly involved in reproduction. Therefore, they are called accessory whorls. Upper two whorls are directly involved in reproduction. […]
Difference Between Red Grapes and Green Grapes
Red Grapes vs Green Grapes Grapes are not climacteric fruits. They are a type of berry. The vines on which they grow are perennial and deciduous. Grapes belong to a genus of fruits known as Vitus. Grapes are an abundant fruit, and it can be found all over the world. Red grapes and green […]
Difference Between Photosystem 1 and Photosystem 2
The key difference between photosystem 1 and photosystem 2 is that the photosystem 1 has a reaction centre composing of chlorophyll a molecule of P700 that absorbs light at a wavelength of 700 nm. On the other hand, the photosystem II has a reaction centre comprising chlorophyll a molecule of P680 that absorbs light at […]
Difference Between Membranous and Nonmembranous Organelles
The key difference between membranous and nonmembranous organelles is that the membranous organelles are absent in prokaryotic cells while nonmembranous organelles are present in both prokaryotic and eukaryotic cells. The cell is the basic unit of living organisms. However, there are two types of cellular organizations namely prokaryotic and eukaryotic. One of the key features […]
