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.Know More
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 in Cells
In plant cells, chloroplasts perform photosynthesis, a process that converts light energy from the sun into chemical energy in the form of glucose. Plants can later use this stored chemical energy to carry out activities integral to life, such as growth and reproduction.Full Answer >
The two cellular structures found in animal cells but not in plant cells are the centrosome and the lysosome. The centrosome is the microtubule-organizing center of the cell, giving rise to the mitotic spindle. The lysosome is the cellular disposal system, breaking down unwanted materials from the cytoplasm.Full Answer >
The largest organelle in plant cells containing the cell sap is the vacuole. Plant cells usually have a single vacuole that can take up 80 percent or more of the volume of a cell.Full Answer >
The nuclear envelope controls the flow of information into and out of the nucleus. It is a porous double membrane that allows the free passage of water, ATP and other small molecules. It regulates the passage of macromolecules, which are much larger, and these are the molecules that carry information.Full Answer >
