Canal System in Porifera: The canal system is a unique feature found in the phylum Porifera, commonly known as sponges. Porifera is a group of multicellular organisms that lack true tissues and organs but possess specialized cells to perform various functions. The canal system in porifera is responsible for water circulation, food capture, and waste removal….
Protozoa: Protozoans are single-celled eukaryotic organisms that are found in a variety of habitats, including water, soil, and the bodies of animals. They can be classified into four main groups based on their locomotion: flagellates, ciliates, amoebae, and sporozoans. The slides are used to study the morphology of protozoans under a microscope. The slides are…

Evolution of Developmental Biology: “Developmental Biology”- Holistic study approach including embryonic development, and all post natal processes such as normal growth, metamorphosis, regeneration and tissue repair at different levels of complexity ranging from molecular to the organism level. Historically, Developmental Biology was known as Embryology. Definition of “Embryology” – study of animal development that exits…
Cleavage Stages of Embryonic Development: Embryonic development is a complex and highly regulated process that begins with the fertilization of an egg by a sperm and continues through various stages to form a multicellular organism. One of the earliest and crucial processes in embryonic development is cleavage. Cleavage refers to a series of rapid cell divisions…
Fertilization: It is the process of two sex cells, or gametes, fusing together to form a new zygote. This process is essential for reproduction in all sexually reproducing organisms. In animals, fertilization typically occurs internally, meaning that the sperm cell fertilizes the egg cell inside the female body. This is in contrast to external fertilization, which…
Types of Eggs: Eggs, the symbol of life’s origins, can take a wide variety of shapes. Eggs exhibit a tremendous diversity, ranging from the absence of yolk to the concentration of nutrients, the distribution of yolk, and even the make-up of their shells. The fascinating world of egg forms and classifications is explored in this…
Gametes: Gametes are reproductive cells that contain a haploid number of chromosomes. This means that they have only one copy of each chromosome, as opposed to the diploid number of chromosomes found in other cells of the body. Gametes are produced in the gonads, which are the reproductive organs of the body. In males, the…
