Animal Cell
Animal Cell definition
Animal cell are the basic unit of life in organism of kingdom animalia. They have true nucleus and specialized structures called organelles that carries out
different functions. They don’t have cell wall.
Animal Cell overview
Eukaryotic cell are distinguished by the presence of nucleolus and other
membrane-bound organelles. Animal cells are considered heterotrophic.
They have mitochondria that are used to create ATP from various
sources. Different organelles performs different functions.
Animal Cell Structure
Nucleus
The nucleus contains a cells DNA. DNA contains instructions for
making proteins which controls all the body activities. Nucleus
regulates which genes are expressed in the cell, which controls cells
activity and functioning depending upon the type of cell. Cell usually
have one nucleus each.
Cell membrane
Cell membrane surrounds the entire cell. The cell membrane is a double
layer made up of phospholipids. It is selectively permeable, meaning it
only allows certain molecules through. This maintains homeostasis
within the cell.
Ribosomes
Ribosomes are where proteins are synthesized. The mRNA chain
travels to the ribosomes via transfer RNA (tRNA) and its sequences is
used to determine the correct placement of amino acids in a chain that
makes up the protein. They are found freely in cell’s cytoplasm, or
attached to the membranes of the endoplasmic reticulum (ER).
Mitochondria
The process of cellular respiration occurs in the mitochondria. Energy
is released in the form of adenosine triphosphate (ATP). ATP powers all
cellular processes, and mitochondria produce a cell’s ATP, so
mitochondria are commonly known as “the powerhouse of the cell”.

Cytosol and all the organelles
within it, except for the nucleus,
are collectively referred to as a
cell’s cytoplasm. The pH is
generally neutral, around 7.
Endoplasmic reticulum
The ER is a network of membranous sacs celled cisternae. There are
two kinds of ER, smooth and rough. Rough ER has ribosomes attached,
smooth ER dos not have ribosomes attached an has functions in making
lipids and steroids hormones and the removing toxic substances.
Golgi apparatus
The Golgi apparatus, also
called the Golgi complex or
Golgi body, is also made up
of cisternae, but the cisternae
are not interconnected like
those of the ER. The Golgi
apparatus receives proteins
from the ER and folds, sorts,
and packages these proteins
into vesicles.
Vesicles
They are used for transporting molecules throughout the cell from one
organelle to another and are also involved in metabolism. Specialized
vesicles called lysosomes contain enzymes that digest large molecules
like carbohydrates, lipids, and proteins into smaller ones.
Cytoskeleton
The cytoskeleton is a network of filaments and tubules found
throughout the cytoplasm of the cell. It has many functions: it gives the
cell shape, provides strength, and stabilizes tissues. There are three
types of cytoskeletal filaments: microfilaments, microtubules, and
intermediate filaments.
