Animal cells have many distinct characteristics when compared to plant cells, including their varied shapes, their many types of organelles, their centrioles, cilia and lysosomes, and their cell-to-cell junctions. Animal cells also lack chloroplasts and cell walls, which are found in plant cells.Continue Reading
The varying and irregular shapes of animal cells are a distinct characteristic, while plant cells have regular, rectangular shapes. This is due mostly to the rigidity of the cell wall that animal cells lack.
Another characteristic of animal cells is the many types of organelles. Among these structures and organelles are the cell membrane, centrioles, cytoplasm, endoplasmic reticulum, golgi complex, lysosomes, microtubules, mitochondria, nucleus, nucleollus, nucleopore, ribosomes, cytoskeleton, cilia, flagella and peroxisomes.
Centrioles, only found in animal cells, are necessary during cell division. They organize the microtubules. Cilia are also characteristic to animal cells. They are protrusions attached to the cell that help the cell to move. Finally, lysosomes are also found exclusively in animal cells. These are enzymes that are necessary during the digestion of nucleic acids.
Finally, animal cells are characterized by their cell-to-cell junctions. These junctions come in three types. Tight junctions form seals between tissues, adhering junctions enable tissues to stretch and gap junctions form channels.Learn more about Cells
Plant and animal cells have many of the same organelles, they both divide to reproduce, and they share similar basic structure. Scientists cite these similarities as evidence that all life evolved from a common ancestor.Full Answer >
Eukaryotic cells all feature a nucleus, and their organelles are enclosed inside membranes. They also have a plasma membrane, which is a layer of phospholipids that surrounds the whole cell, and they feature an internal cytoskeleton.Full Answer >
There are several key differences between plant and animal cells, such as cell wall structure, presence or absence of plastids, lysosomes and centrioles and shape of vacuoles. These characteristics are the primary and most distinct differences between plant and animal cells. However, they only exist in organisms classified as eukaryotic, and occur primarily in central organelles.Full Answer >
The primary differences in the features of plant cells and animal cells are the presence or absence of a cell wall, chloroplasts and centrioles. Plant cells have cell walls and chloroplasts, while animal cells lack such organelles; but instead, they contain centrioles. Additionally, the only plant cells that possess flagella are sex cells, whereas they are more common in a variety of animal cell types.Full Answer >
