Every living thing is made up of one or more microscopic units called cells. Every process needed for life, such as producing energy from food, takes place in the cell. There are many different types of cells, but most share certain features. The cell we will be studying today is the animal cell.
NUCLEUS This is the nucleus. The nucleus is the largest, and most important part of the cell. It is like the brain. NUCLEUS The orange part in the middle is called the nucleolus. This is a very important part of the cell, because this is where ribosomal RNA is produced. Nucleolus Did You Know? The nucleus contains genes inside the cell that hold the information needed to make proteins.
Endoplasmic Reticulum Rough and Smooth ER (endoplasmic reticulum) Rough ER delivers materials through the cell and makes proteins in sacks called cisternae which are sent to the Golgi body. Rough ER is covered with ribosomes that give it a rough appearance, which is probably why it’s called the ROUGH ER Smooth ER transports materials through the cell, and contains enzymes and makes and digests fats and membrane proteins; smooth ER buds off from rough ER, moving the newly-made proteins and fats to the Golgi body, lysosomes, and membranes.
Golgi body (also called the Golgi apparatus or golgi complex) The Golgi Body is a flattened, layered, sac-like organelle that looks like a stack of pancakes (ymmm!) and is located near the nucleus. It produces the membranes that surround the lysosomes, and packages proteins and carbohydrates.
MITOCHONDRIA The mitochondria acts like a cells powerhouse, breaking down substances, and converting them to energy for the cell.
CYTOPLASM cytoplasm The cytoplasm is the jellylike material outside the cell nucleus in which the organelles are located. Its job is to store nutrition and important chemicals for the cell. It also holds everything in place in the cell.
LYSOSOME LYSOSOME Lysosomes are round organelles surrounded by a membrane and containing digestive enzymes. This is where the digestion of cell nutrients takes place.This also where parts of the cell that are no longer needed are disposed of.
RIBOSOMES Ribosomes help build up protein, which is needed for all functions in the cell. RIBOSOMES
The Vacuoles are small, temporary sacs in the cytoplasm, that store liquids and/or fats. They also store waste, and things on the way out of the cell. VACUOLES
These are some of the main parts of the animal cell. The cell membrane, cytoplasm, and nucleus are collectively called the protoplasm. Despite the fact that plant and animal cells are different, they do share some features, such as. . . . The nucleus . The cytoplasm . The cell membrane
All these tiny parts of the cell combined, make a cell, and a cell equals life. Without all of these small, yet important organelles, we would not be alive. Inside these cells, very important things are being done. So, let’s give up a round of applause for the . . . . CELL!!!
