Cell Organelles & Biology

Cell culture is a technique to grow and maintain cells in a Petri dish or flask, which allows for studying the growth, development and other characteristics of cells under controlled conditions.

Chromosomes are made up of bundles of tightly coiled DNA molecules and proteins called histones. In eukaryotic cells, chromosomes are stored in the nuclei.

Flagella and cilia are two types of cellular structures that allow movement in most microorganisms and animal cells, but not in high plant cells.

Transcription is the process of making an RNA copy of a DNA segment. This copy is called a messenger RNA (mRNA) molecule.

Animal and plant cells are eukaryotic cells. They all have nuclei, cell membranes, and organelles (ER, Golgi, ribosomes, and mitochondria). The structures only in plant cells are the cell wall, chloroplast, and vacuole.

What are red blood cells – an overview Red blood cells (RBCs, also called erythrocytes) are the most abundant blood cells. Their function is to carry oxygen from the lungs to all parts of the body. In this article, you will learn the biology and functions of red blood cells. We will discuss why red …

White blood cells are a critical part of our body’s immune system. Types of white blood cells include neutrophils, eosinophils, basophils, monocytes, and lymphocyte.

Nucleus is a double-membrane organelle, and it controls cell activities and carries genetic information to pass to the next generation.

Ribosomes are complex molecular machines that make proteins inside cells. Ribosomes consist of two subunits – larger and smaller, made by a complex of RNA and proteins.

Induced pluripotent stem cells (iPSCs) are pluripotent stem cells that can be generated and reprogrammed directly from somatic cells.
