What is Animal Cell?

An animal cell is the basic building block of all animals, providing structure and helping to regulate the organism’s functions. Animal cells are eukaryotic, meaning they contain a nucleus which holds all the genetic material. The nucleus is surrounded by a membrane, known as the nuclear envelope. Outside of this are other organelles such as mitochondria, ribosomes and endoplasmic reticulum that are responsible for producing energy for the cell or helping it to create proteins. The cytoplasm is made up of water and various molecules that help to control the functions of the cell. This is surrounded by a semi-permeable membrane known as the plasma membrane which acts like a gatekeeper allowing certain substances in while keeping others out. Animal cells also have specialized structures called cilia and flagella that aid in movement, either by helping organisms move through their environment or aiding with internal processes such as fertilization inside animals cells. Animal cells are typically quite small compared to plant cells due to their lack of rigid structures such as cellulose walls or chloroplasts (which convert light energy into chemical energy). This makes them very efficient at carrying out internal processes while minimizing their overall size they only need enough space for organelles to fit within its small walls. They also lack most storage components found in plant cells, relying instead on nearby tissues for nutrients and oxygen supply. The main function of an animal cell is to carry out all necessary chemical reactions needed for life processes from respiration, digestion and growth but it also helps support life outside itself by transmitting signals between different organs in our bodies so we can move around effectively. Additionally, these specialized structures can detect changes in our environment such as temperature or sound waves so we can react accordingly. Overall, animal cells provide us with essential functions while remaining small enough not to take up too much space; they provide us with many essential services without us even knowing it.
