Cells are the basic unit of life, and all living organisms are made up of one or more cells. Within a cell, there are several different parts that all play important roles in the cell's function and survival. These parts of a cell can be divided into two main categories: the cell membrane and the cell interior.

The cell membrane, also known as the plasma membrane, is a thin, flexible barrier that surrounds the cell and separates the inside of the cell from the external environment. It is made up of lipids, or fats, and proteins, and it acts as a selective barrier, allowing certain substances to enter or exit the cell while preventing others from passing through. The cell membrane is vital for maintaining the cell's shape and integrity, as well as regulating the exchange of materials between the cell and its surroundings.

Inside the cell, there are several other important structures that carry out various functions. One of these structures is the cytoplasm, which is a gel-like substance that fills the cell and surrounds the cell's organelles. The cytoplasm is composed of water, salts, and organic molecules, and it serves as a medium for chemical reactions and transport within the cell.

Another important part of the cell is the nucleus, which is a large, spherical structure that contains the cell's genetic material. The nucleus is surrounded by a double membrane called the nuclear envelope, which separates the nucleus from the cytoplasm. Within the nucleus, there are thread-like structures called chromosomes, which contain the cell's DNA. The DNA carries the genetic information that is passed on from one generation to the next, and it is responsible for determining the traits and characteristics of an organism.

Other important organelles found within the cell include the mitochondria, which produce energy for the cell; the endoplasmic reticulum and Golgi apparatus, which are involved in protein synthesis and transportation; and the lysosomes, which contain enzymes that break down waste products and foreign substances.

In summary, cells are made up of several different parts that work together to maintain the cell's function and survival. The cell membrane acts as a barrier, while the cytoplasm, nucleus, and various organelles all play important roles in the cell's metabolism and reproduction. Understanding the structure and function of these parts is essential for understanding how cells work and how they contribute to the overall function of living organisms.

Most of the parts of a cell are suspended in the cytoplasm. Golgi Bodies The golgi apparatus or bodies are flat vesicular structures that are stacked one above the other.

An organelle is a particle, or grouping of macromolecules and polymers, in which have one distinct function. Organs are therefore arrays of cells all working together to perform a bigger picture function.

What this means is that they have not a whole lot of organization within them. The nuclear membrane is porous and allows RNA and proteins to pass in and out of the nucleus. All cells contain specialized, subcellular structures that are adapted to keep the cell alive. Parts of a Cell All cells contain, at an absolute minimum, a cell membrane, genetic material and cytoplasm, also called cytosol. Like plant and fungi cells, an animal cell is eukaryotic, but animal cells lack the cell wall structure found in plant and fungi cell types. Photosynthesis is a process by which light energy from the sun is used to convert carbon dioxide and water molecules into glucose, and is how plants produce food.

This means that the double membranes are aligned as mirror images, like the two sides of your body. DNA and RNA are the genetic materials in which all living organisms have, these tell the cell how to work. More about Kevin and links to his professional work can be found at www. It is a dark and round organelle, protected by a double membrane with permeable pores allowing the transfer of chemicals. In prokaryotes, these float freely in the cytoplasm; in eukaryotes they are typically bound to the endoplasmic reticulum. Nucleolus The nucleus is an organelle that has another organelle inside it. Lysosomes also play an important role in apoptosis AKA programmed cell death.

The Cell Membrane The cell membrane, also called the plasma membrane, is a physical boundary between the cell's internal environment and the outside world. Each single layer is asymmetrical, consisting of individual molecules that bear something of a relationship to squids, or to balloons bearing a few tassels. Vacuole Found in plant cells, the vacuole looks like a large hole but is actually a huge storage unit for the cells products. Other molecules must use the channels in the membrane to gain access to the cell. Cell Membrane The plasma membrane encloses the cell in a bilipid membrane membrane with two lipid layers. These reactions take place on the mitochondrial membrane and are the means by which the ATP molecules are liberated during aerobic respiration. Membranes, Cytoplasm, Organelles, and Cell Walls So what do a lot of these words mean, organelle, membrane, nucleus? Light energy is converted to chemical energy in the chloroplast.

The cell wall supports and protects plant cells, giving them their characteristic rectangular or box-like shape. Nucleoulus The nucleoulus contains the RNA and sends out the RNS to ribosomes along with the blueprints of the protein to be synthesized. A cell has several components that perform different functions. Lysosome This part of an animal cell that is a membranous sac. Lysosomes are the heroes of cells! It is important to realize that inside the cell membranes enclose cytoplasm.

The cell membrane famously consists of a phospholipid bilayer, meaning that it is composed of two identical layers made up of phospholipid molecules or more properly, phosphoglycerolipids. One of its key functions is storage. Ribosomes produce proteins by assembling amino acid sequences according to the instructions contained in the genetic code. These organelles are the cell's ground troops, continually making sure that all of the cell's moment-to-moment needs are met. DNA copies itself onto RNA, and then the RNA is sent through pores in the nuclear envelope to Ribosomes. Golgi Apparatus The Golgi apparatus consists of membrane sacs called cristenea.

This article will deal mainly with eukaryotes as these are the ones whom have membrane bound organelles which can be easily identified and studied. It surrounds the cell membrane and helps maintain the pressure within the cell. Mitochondria Cells need energy to power their biochemical reactions, and most of that energy is released by mitochondria. The name of the total contents of the cell, minus the nucleus, is the cytoplasm the cytosol plus the suspended organelles. The review questions below will help you refresh your memory.
