Tissue is an organized group of similar or different cells that work together to perform specific functions necessary for an organism’s survival and operation, together. Tissues form the fundamental building blocks building of organs and systems in multicellular life forms and bridge the structural and functional gaps between individual cells and the entire organism. These specialized cell communities carry out complex biological processes such as growth, repair, protection, movement and communi

National Cancer Week is a special week held annually in April 1–7 in Türkiye, aimed at raising public awareness about cancer and emphasizing the importance of early diagnosis. First adopted in 1956 on the recommendation of the Cancer Research and Fight Organization, this week is now observed through various activities organized by health institutions and schools.What Is Cancer?Cancer is a disease characterized by the uncontrolled division and multiplication of certain cells in the body, which ga

The cell is the fundamental building block of all living organisms and the smallest unit that carries out all functions of life. Cells constitute the structural and functional units of living organisms. Living organisms are classified into two main groups based on cellular structure: prokaryotic and eukaryotic cells. These two groups differ in their cellular architecture, the organelles they contain, and the organization of their genetic material.Prokaryotic CellsProkaryotes represent simple org

Cells are the smallest building blocks of living organisms. Just like a city, each cell contains many specialized parts that work together. One of these parts is the endoplasmic reticulum. Although its name may seem long and complex, you’ll find it fascinating once you learn what it does!What Is the Endoplasmic Reticulum?The endoplasmic reticulum (abbreviated as ER) is a folded, tubular structure inside the cell. It functions like a factory and is located very close to the cell nucleus, with whi

Ribosomes are like small factories that produce the proteins responsible for carrying out essential functions throughout our body. Let’s explore this amazing world!What Are Ribosomes?Ribosomes are tiny structures found inside our cells that make proteins. Proteins are vital for our body to move, digest food, and even breathe. Without ribosomes, our cells could not perform these tasks! That is why we call them the “protein factories of the cell.”Ribosomes are so small that we cannot see them with

Mitochondria are organelles found in eukaryotic cells that are primarily involved in cellular energy production. These structures, which are surrounded by a double membrane, carry out cellular respiration processes necessary for the synthesis of adenosine triphosphate (ATP). Additionally, mitochondria play essential roles in regulating metabolic functions within the cell, the cell cycle, inheritance, and processes such as apoptosis.StructureMitochondria are organelles enclosed by a double membra

Cell culture is the process of growing and multiplying cells derived from living organisms under controlled laboratory conditions. This technical, used as a common in Modern biotechnology and medical research, has made significant importance in numerous fields including drug development, cancer research, and texture engineering like.A scientist performing cell culture in a laboratory environment.

The cell membrane (also known as the plasma membrane, cell membrane, or cytoplasmic membrane) is a biological structure that separates the cytoplasm of all living cells from the external environment and maintains cellular integrity. By surrounding the cell, it isolates the cytoplasm and organelles from the external milieu and regulates the exchange of materials between the inside and outside of the cell. This property enables the maintenance of intracellular balance (homeostasis).The cell membra

A vacuole is a structure predominantly located in the central region of plant cells, fulfilling various biochemical and physiological functions. By maintaining intracellular homeostasis and contributing to processes such as storage and recycling of substances, vacuoles are considered essential components of cell biology. The structural diversity of vacuoles, which varies depending on the organism type, cell type, and physiological conditions, has necessitated extensive research into their functi
