Summary of the function of the Smooth ER: Protein synthesis Golgi apparatus Processes and packages proteins and transports them to other parts of the cell or outside the cell.
Nucleus- The nucleus is the control center of the cell. It is the largest organelle in the cell and it contains the DNA of the cell. DNA Deoxyribonucleic Acid contains all the information for cells to live, perform their functions and reproduce.
Inside the nucleus is another organelle called the nucleolus. The nucleolus is responsible for making ribosomes. The circles on the surface of the nucleus are the nuclear pores.
These are where ribosomes, and other materials move in and out of the nucleus. There are two types of ER. When ribosomes are attached it is called rough ER and smooth ER when there are no ribosomes attached.
The rough endoplasmic reticulum is where most protein synthesis occurs in the cell. The function of the smooth endoplasmic reticulum is to synthesize lipids in the cell. The smooth ER also helps in the detoxification of harmful substances in the cell. Ribosomes are made up of two parts, called subunits.
They get their names from their size. One unit is larger than the other so they are called large and small subunits. Both these subunits are necessary for protein synthesis in the cell. When the two units are docked together with a special information unit called messenger RNA, they make proteins.
Some ribosomes are found in the cytoplasm, but most are attached to the endoplasmic reticulum. While attached to the ER, ribosomes make proteins that the cell needs and also ones to be exported from the cell for work elsewhere in the body. Just like our postal packages, which should have a correct shipping address, the proteins produced in the ER should be correctly sent to their respective address.
It is a very important step in protein synthesis. If the Golgi complex makes a mistake in shipping the proteins to the right address, certain functions in the cell may stop.
This organelle was named after an Italian physician, Camillo Golgi. He was the first person to describe this organelle in the cell.
It is also the only organelle that is capitalized. This organelle packages the energy from the food you eat into ATP molecules. Every type of cell has a different amount of mitochondria plural. There are more mitochondria in cells that have to perform lots of work, for example- your leg muscle cells, heart muscle cells etc.
Other cells need less energy to do their work and have less mitochondria. In this organelle the light energy of the sun is converted into chemical energy.
Chloroplasts are found only in plant cells not animal cells. The chemical energy that is produced by chloroplasts is finally used to make carbohydrates like starch that get stored in the plant.
Chloroplasts contain tiny pigments called chlorophylls. Chlorophylls are responsible for trapping the light energy from the sun. This organelle helps store and transport products produced by the cell. The vesicles are the transport and delivery vehicles like our mail and Federal Express trucks.
Some vesicles deliver materials to parts of the cell and others transport materials outside the cell in a process called exocytosis. This space is called the vacuole. Cytoplasm - A term for all the contents of a cell other than the nucleus. Even though the cartoon drawings do not look like it, the cytoplasm contains mostly water.
Some fun facts about water and the human body: Adult bodies are about 50 to 65 percent water. The human brain is about 75 percent water. Cell walls provide protection and support for plants.Animal cell is a form of eukaryotic cell that makes up the body tissues and, thus, the organs.
This cell is pretty distinct from a plant cell.
Cell wall and chloroplast are present in plant cells, while animal cells do not have cell walls. Animal Cell Structure. Animal cells are typical of the eukaryotic cell, enclosed by a plasma membrane and containing a membrane-bound nucleus and organelles.
Unlike the eukaryotic cells of plants and fungi, animal cells do not have a cell wall. Animal Cell Parts Animal cells depict various irregular shapes and sizes and are visible only under the microscope. This BiologyWise article elaborates on the definition and the function of the parts of animal cell; it being the fundamental unit of life.
For example, in plant cells, there are more types of organelles than are found in animal cells. Below are some names and descriptions of organelles commonly found in cells.
There is also an interactive cell viewer and game that can be used to learn about the parts of animal and plant cells.

During cell division (mitosis), the centrosome divides and the two parts move to opposite sides of the dividing cell. The centriole is the dense center of the centrosome.
cytoplasm - the jellylike material outside the cell nucleus in which the organelles are located.
