Pollination in a flower is a transferring mechanism of pollen grains from the anther (flower’s male reproductory part or stamen) to the stigma (flower’s female reproductive part or gynoecium). It is the primary stage that results in the flower’s fertilization. The passage of pollen grains from an anther to a stigma occurs via pollinating agents …
The bilayer cell membrane is a membranous structure, which consists of two phospholipid layers. Thus, a cell membrane also refers to a phospholipid bilayer membrane composed of many phospholipid molecules. A structure of a phospholipid molecule consists of a hydrophilic head, a phosphate molecule, a glycerol molecule and two hydrophobic fatty acid tail. The phospholipid …
Gynoecium, carpel or pistil primarily comprises three structures, namely stigma, style and ovary. It accounts for the flower’s female reproductive part that carries the female gametes or ovules within an ovary. Towards the gynoecium base, the pedicle or thalamus provides support to the female reproductive part and the other parts as well. An ovary is …
Riboflavin or Vitamin B-2 belongs to the Vitamin-B group, which are of eight kinds viz. vitamin B-1, B-2, B-3, B-5, B-6, B-7, B-9, B-12. It plays a crucial role in converting and breaking down protein, fats, and carbohydrates to produce energy. Vitamin B-2 converts complex carbohydrates, proteins and fat into simple sugar, amino acids and …
Xanthophyll is a type of accessory pigment or phytochemicals, which belongs to the class of “Carotenoids”. In many vascular plants and algae, xanthophylls act as the light-harvesting protein complexes. Xanthophylls are rich in antioxidants, which prevent the cells from damaging. In photosynthetic eukaryotes, the xanthophylls are usually bound to the chlorophyll molecules. Xanthophylls are the …
The difference between template and coding strand is mainly due to the following properties: directional polarity and function. Both template and coding strand are the two distinct strand of the double-stranded DNA, in which the former works as a base to transcribe mRNA, and the latter determines the correct base sequence of the mRNA. Directional …
The difference between flagella and pili is due to the difference in the properties like structure, origination and functional role. Both are the two common types of surface appendages, which aid in locomotion and attachment of the organisms. Structure: The structure of flagellum appears whip-like, whereas pili appear thread or hair-like. Origination: The emergence of …
The difference between amphibians and reptiles is mainly due to the differences in the properties like the existence of dual life cycle, type of fertilization and skin type. Both amphibians and reptiles are the animals belonging to the phylum “Chordata” and considered as “Cold-blooded animals”. Life cycle: Amphibians have dual existence in their life cycle, …
The difference between cerebrum and cerebellum is mainly due to the following properties like size, constitution to brain and location. They both contribute to the human brain or central nervous system and plays an integral role in our everyday life. The size of the cerebrum is the largest part of the brain, while cerebellum is much …
The difference between the small intestine and large intestine is mainly due to the three factors like length, diameter and involvement in the digestion. Both small and large intestine belongs to the intestinal system. Length: The small intestine’s length is 9 m that is larger than the large intestine whose length is about 1.5 m. …
