Animal cells are the basic unit of life for all animals. They are incredibly complex structures, and understanding their structure and function is essential for understanding biology. A cell tour is a guided exploration of the different components of an animal cell, and it is a great way to learn about the cell’s structure and function.

Cell Membrane

Tour of an animal cell structures and functions bioflix tutorial

The cell membrane is a thin, flexible layer that surrounds the cell. It protects the cell from its surroundings and regulates the passage of substances into and out of the cell. The cell membrane is made up of a phospholipid bilayer, which is a double layer of phospholipids.

Phospholipids are molecules that have a hydrophilic (water-loving) head and a hydrophobic (water-hating) tail. The hydrophilic heads face outward, while the hydrophobic tails face inward. This arrangement creates a barrier that is impermeable to most substances.

Membrane Proteins

The cell membrane is not completely impermeable. It contains membrane proteins that allow certain substances to enter and leave the cell. There are two main types of membrane proteins: integral membrane proteins and peripheral membrane proteins. Integral membrane proteins span the entire cell membrane, while peripheral membrane proteins are attached to the surface of the cell membrane.

Acrylic painting is a popular medium for beginners due to its versatility and ease of use. For those looking to get started, there are comprehensive tutorials available online that provide step-by-step instructions. Acrylic painting tutorial for beginners step by step guides cover everything from choosing the right materials to creating basic shapes and blending colors.


The cytoplasm is the gel-like substance that fills the cell. It is the site of many cellular activities, including protein synthesis, RNA synthesis, and DNA replication. The cytoplasm contains a number of organelles, which are small structures that perform specific functions within the cell.

Organelles, Tour of an animal cell structures and functions bioflix tutorial

  • Ribosomesare small, round organelles that are responsible for protein synthesis.
  • Endoplasmic reticulumis a network of membranes that folds and transports proteins.
  • Golgi apparatusis a stack of flattened sacs that modifies and packages proteins.
  • Mitochondriaare small, bean-shaped organelles that produce energy for the cell.
  • Lysosomesare small, spherical organelles that contain digestive enzymes.
  • Peroxisomesare small, spherical organelles that contain enzymes that detoxify harmful substances.

The nucleus is a large, round organelle that is surrounded by a nuclear envelope. It is the control center of the cell and contains the cell’s DNA. The nucleus is responsible for regulating gene expression and directing the cell’s activities.

Components of the Nucleus

  • Nuclear envelopeis a double membrane that surrounds the nucleus.
  • Nucleolusis a small, dense region within the nucleus that is responsible for ribosome synthesis.
  • Chromatinis a complex of DNA and proteins that is found within the nucleus.

Endoplasmic Reticulum (ER)

The endoplasmic reticulum is a network of membranes that folds and transports proteins. There are two types of endoplasmic reticulum: rough endoplasmic reticulum and smooth endoplasmic reticulum. Rough endoplasmic reticulum is studded with ribosomes, while smooth endoplasmic reticulum is not.

Functions of the ER

  • Protein synthesis: The rough endoplasmic reticulum synthesizes proteins.
  • Protein folding: The endoplasmic reticulum folds proteins into their proper shape.
  • Protein transport: The endoplasmic reticulum transports proteins to the Golgi apparatus.
