Q:

What are some facts about animal cells?

A:

Quick Answer

An important fact about animal cells is that they are eukaryotic cells. Although plant and animal cells are both eukaryotic, animal cells have different organelles and are smaller than plant cells. An organism can be composed of up to trillions of animal cells, with hundreds of different types and functions.

Full Answer

Animal cells are eukaryotic cells, which are cells with a nucleus and organelles inside of cell membranes. A nucleus contains the DNA material for eukaryotic cells. Organelles are structures within a cell that carries out specific functions, such as providing energy, producing hormones or creating enzymes.

Plant and animal cells are both eukaryotic cells, but they have significant differences in their structures. An animal cell is generally smaller than a plant cell. As opposed to a plant cell, an animal cell varies in size is irregular in shape. An animal cell does not have a large vacuole or cell wall, but it has organelles such as centrioles, lysosomes, cilia and flagella.

Trillions of animal cells make up an organism. Cells differ in shapes and size based on their specific functions. There are hundreds of different types of animal cells within the human body, each responsible for a different biological function.

    What do plant and animal cells have in common?

    A:

    Plant and animal cells both have a nucleus, endoplasmic reticulum, ribosomes, a Golgi apparatus, vesicles, mitochondria and a cell membrane. Each of these components work together to keep the cell healthy and functioning properly. In addition, plant and animal cells are eukarotic, meaning they are multicellular.

  • Q:

    Why don't animal cells have chloroplasts?

    A:

    Animal cells don't have chloroplasts because animals aren't green plants. Chloroplasts are organelles, or small, specialized bodies in plant cells that contain chlorophyll and help with the process of photosynthesis. Like mitochondria, chloroplasts have their own DNA.
