cells the smallest living unit of an organism all cells have three things in common no matter what type of cell they are  all have a cell membrane which separates the inside of the cell from its environment cytoplasm which is a jelly-like fluid and DNA which is the cell's genetic material there are two broad categories of cells category is eukaryotic cells they have organelles which include the nucleus and other special parts  UCare next cells are more advanced complex cells such as those found in plants and animals the second category is Procare next cells they don't have a nucleus or membrane enclosed organelles they do have genetic material but it's not contained within a nucleus prokaryotic cells are always one celled or unicellular organisms such as bacteria so what are organelles organelle means little organ organelles are the specialized parts of a cell I have unique jobs to perform let's start with the nucleus the control center of the cell  the nucleus contain DNA or genetic material DNA dictates what the cell is going to do and how it's going to do it chromatin is the Tangled spread out form of DNA found inside the nuclear membrane when a cell is ready to divide DNA condense Lucinda structures known as chromosomes the nucleus also contains a nucleolus which is a structure where ribosomes are made  after ribosomes leave the nucleus they will have the important job of synthesizing or making proteins  outside the nucleus the zones and the rest of the organelles float around in the cytoplasm which is the jelly like substance  ribosomes May Wonder Haley within the cytoplasm or attached to the endoplasmic reticulum sometimes abbreviated as ER there are two time what's the VR rough ER has ribosomes attached to it and smooth ER doesn't have ribosomes attached to it the endoplasmic reticulum is a membrane enclosed passageway for transporting materials such as the proteins synthesized by ribosomes proteins and other materials emerge from the endoplasmic reticulum in small vesicles where the Golgi apparatus sometimes called the Golgi body receives them  as proteins move through the Golgi body they're customized into forms that the cell can use  the Golgi body does this by folding the proteins into usable or adding other materials on to them such as lipids door carbohydrates vacuoles are sac-like structures that store different materials here in this plant cell the central vacuole stores water going back to the animal cell you will see an organelle called a lysosome lysosomes are the garbage collectors that taken damaged or worn out cell parts they are filled with enzymes that break down the cellular debris the mitochondrion is an organelle that is the PowerHouse for both animal and plant cells during a process called tell dealer respiration the mitochondria make ATP molecules that provide the energy for all of the cell's activities cells that need more energy have more mitochondria meanwhile the cell maintains its shape cytoskeleton  cytoskeleton includes the threadlike microfilaments which are made of protein and micro Wheels which are thin hollow tubes  some organisms such as plants that are photoautotrophic meaning they capture sunlight for energy  have cells with an organelle called a chloroplast the chloroplast is where photosynthesis happens it's green because it has a green pigment called chlorophyll plant cells also have a cell wall outside of their cell membranes that shape support and protect the plant cell cells never have a cell wall there are many other unique structures that only some cells have here are just a few in humans for example the respiratory tract is lined with cells that have cilia these are microscopic hair-like projections that move in waves this feature helps trap inhaled particles in the air and expels them when you cough another unique feature in some cells is flagella some bacteria have flagella a flagellum is like littletale that can help a cell move or Propel itself the only human cell that has a flagellum is a sperm cell in summary remember eukaryotic cells are plant and animal cells with a nucleus and membrane enclosed Janelle's  while prokaryotic cells are unicellular organisms without these things all cells have a cell membrane cytoplasm and genetic material and even though only plant cells have chloroplasts both plant and animal cells have mitochondria
