Golgi Apparatus (Golgi Complex)

Golgi Apparatus

The Golgi apparatus, aka the Golgi complex, is one of the most important components in the structure of the cell. This cellular organelle was named after the Italian biologist Camillo Golgi, who discovered it back in 1898. The Golgi apparatus has the appearance of a complex of cavities bounded by single membranes. In fact, the Golgi apparatus is the membrane structure of a eukaryotic cell.

Chemosynthesis

Chemosynthesis

What is chemosynthesis? The process of chemosynthesis is a unique phenomenon in biology. Chemosynthesis is an unusual type of nutrition of bacteria, based on the assimilation of carbon dioxide СО2 due to the oxidation of inorganic compounds. According to scientists, chemosynthesis is the oldest type of autotrophic nutrition (such nutrition, when the body itself synthesizes organic matter from inorganic), which could appear even earlier than photosynthesis.

Chromosomes

Chromosome

Chromosomes are nucleoprotein structures of a eukaryotic cell. Most of the genetic information is stored in chromosomes. Due to its ability to reproduce itself, it is the chromosomes that provide the genetic link between generations. Chromosomes are formed from a long DNA molecule, which contains a linear group of many genes, and all genetic information, whether it be about a human, an animal, a plant, or any other living creature.

Photosynthesis

фотосинтез

What is photosynthesis? The process of photosynthesis is one of the most important biological processes occurring in Nature. Organic substances are formed from carbon dioxide and water under the action of light; this phenomenon is called photosynthesis. The release of oxygen (vital for the existence of life on our amazing planet) is the most important product of photosynthesis.

Cell Membrane

Cell Membrane

It’s no secret that all living beings on our planet are made up of cells, these countless “atoms” of organic matter. The cells, in turn, are surrounded by a special protective membrane, that plays a very important role in the life of the cell. Functions of the cell membrane are not limited only to the protection of the cell, but constitute the most complex mechanism involved in the reproduction, nutrition, and regeneration of the cell.

Vacuole

Vacuole

Vacuoles are one-membrane cellular organelles and important components of a eukaryotic cell (the eukaryotic cell has a nucleus and a membrane – outer shell). However, not all eukaryotic cells have vacuoles among their organelles. Vacuoles are mainly found in plant and fungal cells. Do animal cells have vacuoles? Yes, animal cells do have vacuoles, but they are smaller, larger in number (plant cells usually have just one or a few large vacuoles) and serve a somewhat different purpose than those of plants.

Mitosis vs Meiosis: Differences and Similarities

Mitosis vs Meiosis

There are many interesting and confusing topics in the multifaceted science of biology. One of them is the ways of cell division: mitosis and meiosis. At first look, there is a similarity between mitosis and meiosis – cell division occurs there and there, but at the same time there are significant differences between them. So, how is meiosis different from mitosis? In order to answer this question, first of all, let’s find out: what is mitosis and what is meiosis.

Cytoplasm: Definition, Structure and Functions

Cytoplasm

What is cytoplasm? Cytoplasm is one of the main parts of the eukaryotic cell. Cytoplasm plays a very important role in the life of a cell; it unites all cellular structures, facilitates their interaction with each other. Besides this, the nucleus of the cell and all organelles are located in the cytoplasm. In other words, cytoplasm is the area of space outside the nucleus that consists of all cell organelles.

Mitochondria: Structure, Function and Role in the Cell

Mitochondria

Discovery of mitochondria happened back in the 19th century. They attracted the attention of biologists by their elongated zigzag-like form. What do mitochondria mean in science? The term “mitochondria” is composed of two Greek words: “mitos” – string and “chondros” – grain. In our article, we’ll talk about why the mitochondria are so important, and what is the role of mitochondria in the cell

Cell Organelles and Their Functions

Cell Organelles

Cell organelles are specialized structures of the cell. They are responsible for various important and vital functions. Each organelle contributes in its own way to help the cell function as a whole. As the body has many different organs, the cell has many different organelles. This is the simplest organelle definition.
