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 are examples of diploid cells?

    A:

    Diploid cells include all animal cells, including those of humans. They are also found in the cells of flowering plants, gymnosperms and in one of the two generations of algae and lower plants. Diploid cells are cells containing chromosomes, which exist in pairs.

  • Q:

    Why do animal cells not contain cell walls?

    A:

    Animal cells do not contain cell walls because cell walls prevent specialization, and individual animal cells do not need protection from the outside environment. The evolution of cells without walls also meant they could connect together, which led to animals becoming the most complex organisms on Earth.

  • Q:

    What is the function of a centriole?

    A:

    A centriole is a small cylindrical organelle in animal cells that employs materials to form centrosomes and cilia, the projections of the cells that are responsible for the body’s movement and sensory functions. During cell division, the centriole is specifically arranged to aid the processes of mitosis and meiosis. A centriole remains in close proximity with another to form a pair (centrosome).
