About Animal Cell
The cells of animals are advanced and complex. Along with plants and fungi, the cells of animals are eukaryotic. Eukaryotic cells are relatively large cells with a nucleus and specialized structures called organelles.
Although animal cells can vary considerably depending on their purpose, there are some general characteristics that are common to all cells. These include structures such as the plasma membrane, cytoplasm, nucleus, mitochondria, and ribosomes.
Animal cells have a number of organelles and structures that perform specific functions for the cell. The huge varieties of cells that have evolved to fulfill different purposes do not always have all the same organelles or structures.
Animal cells have slight differences from the eukaryotic cells of plants and fungi. The clear differences are the lack of cell walls, chloroplasts, and vacuoles and the presence of flagella, lysosomes, and centrosomes in animal cells.
Plant and fungal cells have cell walls. A cell wall is an external structure that surrounds the plasma membrane and provides protection and structural support. Plant cells also have chloroplasts and vacuoles. Chloroplasts are the site of photosynthesis and vacuoles are large sac-like organelles used to store substances.
Plant cells lack flagella, lysosomes, and centrosomes. Fungal cells typically have lysosomes and centrosomes but very few species have flagella. The main difference between fungal and animal cells is the presence of a cell wall in fungal cells.
Here are some important points about animal cells:
• Animal cells are typically large, specialized eukaryotic cells – they contain a nucleus and numerous organelles.
• The plasma membrane surrounds an animal cell.
• Almost a cell’s entire DNA is kept inside its nucleus.
• Endoplasmic reticulum (ER) is a network of membranes connected to the nucleus – it includes the smooth ER and the rough ER.
• Cellular respiration occurs in the mitochondria.
• Ribosomes produce proteins – they can be found in the endoplasmic reticulum or freely floating.
• Animal cells have lysosomes for digestion, centrosomes to help with cell division, and sometimes flagella to help with movement – none of these three organelles are found in plant cells.
• The cells of animals lack cell walls, chloroplasts, and vacuoles which are all found in plant cells.
• Different types of specialized cells are found in different tissues and have features relative to their function e.g. nerve cells have axons and dendrites to send and receive messages.
Some Interesting Animal Cell Facts
Not all cells have a nucleus
Animal cells, in general, are eukaryotic, which means they have a nucleus. However, not all animal cells have a nucleus. For example, the red blood cells don’t have a nucleus since the cells don’t need to multiply by meiosis or mitosis they don’t require a nucleus. The lack of a nucleus allows them to carry more hemoglobin in the cell.
Cells are totipotency
The stem cells in animals are totipotent. This means they can convert into any required cell the body needs.
Cells can repair themselves
During the daily activity, the cell can face some malfunction in the RNA and DNA strands amongst other things. The cell has the functionality to correct these malfunctions on their own immediately.
Cells are self-destructive
No that doesn’t mean the cells just automatically self-destruct. If a cell is injured or has defects in the DNA, it self-destructs so it doesn’t impact other cells.
The Cell is 70% water
70% of the cell is water while the remaining content consists of carbohydrates, proteins, lipids, etc.
Cells are self-sufficient
Cells have nan chemical factories that provide it everything it needs. These factories generate whatever is required for the cell so that it can do the work required.
Cells are small
Animal cells like any cell are not visible to the naked eye. They are anywhere from 1 to 100 micrometers so you will need a microscope to see them.
The cytoplasm in the cell helps it maintain its shape
The cytoskeleton helps the cell maintain its shape. It is found inside the cytoplasm of the cell which is made up of proteins.
Nucleus when present isn’t always in the center
The nucleus is the most important element within a cell and therefore there is a misconception that it is always found in the center of the cell. This is not always true the nucleus can be located in any part of the cell.
