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 …
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 …
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 …
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 …
Induced pluripotent stem cells (iPSCs) are pluripotent stem cells that can be generated and reprogrammed directly from somatic cells.
Cardiomyocytes are the muscle cells that make up the heart muscle. Cardiomyocytes go through a contraction-relaxation cycle that enables cardiac muscles to pump blood throughout …
A centrosome comprises two centrioles that serve as microtubule organizing center (MTOC). Its function is to attach to the centromeres of sister chromatids, and separate …
The cytoskeleton is a network of filament proteins that extends throughout a cell. It gives cell shape, organizes organelles, involves molecule transport, cell division, cell …
The cell membrane is a lipid bilayer that separates the interior of cells from the outside space and protects the cells from the surrounding environment.
Endoplasmic reticulum (ER) is an internal membrane that forms branching networks of many interconnected sacs and tubes inside cells. Rough ER stays closer to the …
The peroxisome is a spherical membrane-bound organelle responsible for the fatty acid breakdown and the conversion of hydrogen peroxide into water and oxygen.
All living organisms fall into one of two categories: Eukaryotes (plants, animals, and fungi) or Prokaryotes (bacteria and archaea). Prokaryotes are unicellular organisms that don’t …
Lysosomes are small organelles that work as the recycling center in the cells. Many lysosomal digesting enzymes break down macromolecules, so they can be reuse …
Mitochondrion is a rod-shaped organelle and its function is to generate energy (ATP) for the cell. Mitochondria contain their own DNA that enconde 13 proteins.
The vacuole is a membrane-bound organelle that is present in all plant cells. The main function is for storage, defense, and acting as a space …
The chloroplast main function is to convert energy from the Sun into glucose for growth, a process called photosynthesis. They are in plants and certain …
Golgi apparatus is a membrane-bound organelle found in most eukaryotic cells. The function of Golgi apparatus is to process proteins and send proteins to different …
A cell organelle is a tiny cellular structure that performs specific functions within a cell, such as a nucleus, mitochondria, ER, ribosomes, lysosomes and Golgi.
Plant cells share many organelles in common with animal cells. There are three unique features in plant cells, cell wall, vacuole, and chloroplast.
Mitosis is a process of cell division, one cell divides and produces two new cells that are genetically identical.
Cell division is necessary for the growth of organisms, repair of damaged tissues, healing and regeneration, and reproduction.
Autophagosomes break down the misfunctioned organelles and recycle the nutrient. Endosomes bring outside material into cells.
Use this guide to build a creative animal cell model using household items. You will be amazed how much cell biology you will learn.
We choose fruit and vegetable to create our own cell model project. For example, we choose avocado seed for representing the cell nucleus.
