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.
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 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 main difference between plant cells and animals cells is that plant cells possess a cell wall and animal cells do not. Animal cells have an irregular shape, and plant cells have a fixed, rectangular shape.Full Answer >
Animal cells do not have a cell wall. Instead, animal cells have a cell membrane that protects the organelles inside of the cell and allows selective compounds to move in and out of the cell.Full Answer >
In an animal cell, the cytoplasm is a semi-liquid substance that holds all the cell's organelles except the nucleus. It also acts as a repository for amino acids, sugars and other important nutrients used in the regular life of the cell. Finally, the cytoplasm stores a cell's waste until it is flushed from the cell.Full Answer >
