The cell cycle is a series of ordered events involving the growth of the cell and cell division, producing two new daughter cells. All cells reproduce by dividing into two more new daughter cells from each parent cell.  Cell division Cell division is a very important process in all living organisms, and this repeating cell […]

The life cycle of a butterfly is amazing. Butterflies have four life stages: egg, larva (caterpillar), pupa (chrysalis), and mature butterfly. One of the things that makes seeing and raising butterflies so enjoyable is that each of the four stages is distinct from the others. The Egg of the Butterfly The egg stage lasts on

What is Budding? Budding is an asexual method of creating new organisms. A small portion of the parent’s body is used to create a new organism. The bud that is formed separates to become a new organism. As it grows, the newly formed organism stays attached. The new organism is separated from its parent when it matures, leaving behind

Reproduction is a process through which all living things generate their kind. They do it either through  Sexual or asexual reproduction. Yeasts can reproduce sexually or asexually, with the latter being more prevalent.  Budding is the process through which yeast multiply asexually. Asexual reproduction is a reproduction method in which kids are produced by a

Buds refer to a state of beginning development in a general sense. The term refers to the formation of a bud, which may occur in both monocellular (e.g. bacteria) and various multicellular organisms such as sponges and plants. Certain single-celled organisms undergo cell budding, which is an asexual process. One Budding example is bacteria, which

We can start the biological species concept by introducing three prominent species concepts. Though there are many more prominent concepts of species, introducing only three will be sufficient. The species concept which is the most common in biology literature is Mayr’s (1970) biological species concept.  The ecological species concept defines that particular species taxon as

Introduction Reproduction is a biological process that is required in order for a race or species to survive and flourish. A species’s ability to preserve its continuity is therefore dependent on this mechanism. Depending on the type of organism, there are various types of reproduction available, ranging from the most basic asexual type to the

Introduction  A cell replicates its DNA during binary fission and separates into two daughter cells. After mitosis, each cell has a copy of the parent DNA. For example; amoeba, bacteria and most single-celled creatures follow this mechanism. Binary fission might be as old as life itself, dating back over 3.5 billion years. Since then, the

Autogamy, also known as self-fertilisation, is the fusion of two gametes that are derived from the same individual. Autogamy is most commonly observed in the form of self-pollination, which is a reproductive strategy used by a large number of flowering plant species. There have been reports of protist species adopting autogamy as a mode of

Asexual reproduction is when a single parent gives birth to a new child. The new people created are genetically and physically identical to their parents, hinting that they are clones. Both multicellular and unicellular species exhibit asexual reproduction. There will be no gamete fusion, and the set of chromosomes will remain the same. Apart from
