Cells are the fundamental units of life. A human body possesses more than 200 different types of cells. Each type of cell is specialized to perform a particular function. They can function alone as well as together by forming a tissue. The shape and structure of a cell depend upon the functionality of the cell. We will also study animal cells. The animal cell is made up of three main parts: cell membrane, nucleus, and cytoplasm whereas the plant cell is made up of the cell wall, cell membrane, nucleus, and cytoplasm.

There are three types of cells found in humans, namely, Red blood cells, Smooth muscle cells, and the Nerve cell.  RBCs contain the pigment hemoglobin, which imparts the red color to the blood. . Smooth muscle cells are involuntary muscles and are controlled by the brain while Nerve cells carry nerve impulses and transfer messages. The ovum is the female gamete and the sperm cell is the male gamete.

The structural and functional unit of life is called the cell. The animal cell is made up of three main parts: cell membrane, nucleus, and cytoplasm. The cell contains organelles like ribosomes, endoplasmic reticulum, Golgi bodies, mitochondria, lysosomes. In this virtual tour activity, we will study what functions these cells perform.

Now we will observe and learn about the structure of a plant cell in this virtual tour activity. The plant cell is made up of the cell wall, cell membrane, nucleus, and cytoplasm. It contains various organelles like Endoplasmic Reticulum, Golgi apparatus, Large Vacuole, Mitochondria, Ribosomes, and Plastids like chloroplast, Vesicles, etcetera. and learned about their functions.
