The plasma membrane is a thin membrane that surrounds and protects a living cell. It is present in every living cells (bacteria, plants, and animals). The membrane separates the inner content of the cell (cytoplasm, […]
Producer protists: Producer protists are unicellular. Many of them produce their foods using sunlight and CO2. Like green plants, producer protists contain chlorophyll a, chlorophyll c pigments, peridinin, and diadinoxanthin pigments. Zooxanthellae (dinoflagellates) are mostly photosynthetic protists. Some protozoa […]
Cellulose [(C6H10O5)n] is a natural homopolymer and the main structural component of the plant cell wall. Cellulose is the most ubiquitously found organic molecule on earth. Microorganisms, algae, and plants synthesize cellulose fibers from glucose molecules […]
Antibiotics are antimicrobial substances widely used as medications to treat and prevent bacterial and fungal infections. According to their origins, antibiotics can be divided into natural, semi-synthetic, and synthetic. Antibiotics are synthesized bacteria and fungi. […]
Corpora quadrigemina is the brain structure responsible for vision formation in rabbits. The corpora quadrigemina is a part of the midbrain or mesencephalon. The corpora quadrigemina is located on the dorsal surface of the midbrain. […]
The chromosome in a eukaryotic organism is composed of deoxyribonucleic acid (DNA) and proteins (histones and non-histone proteins). The chromosomes are localized in the nucleoplasm inside the nucleus. The nuclear membrane or the nuclear envelop […]
Cutaneous respiration is a type of respiration where the organism breath through the skin. Due to the amphibious nature, frogs respire through gills (branchial respiration), skin (cutaneous respiration), buccal cavity (buccopharyngeal respiration), and lungs (pulmonary […]

The inner lining of the uterine wall is called the endometrium. The uterus is a hollow muscular secondary sex organ of the female reproductive system. After fertilization, the egg implant itself in the endometrial lining of the uterus. The egg gets […]
A gene in a eukaryotic organism contains two kinds of nucleotide sequences. They are Exon and Intron. The Exons are expressed nucleotide sequences of a gene and take part in protein synthesis. On the other […]
