A plant cell consists of many organelles. Each one of them plays its own role to make the cell function correctly. If the cell was missing a organelle not would not function the way it’s meant to. What a plant cell contains Nucleus Nucleolous Golgi Bodies Ribosomes Lysosomes Rough and smooth Endoplasmis Reticulum Mitochondria Microtubules Cytoplasm Plasma Membrane Plastids Vacuole Chloroplasts Function Nucleus- the nucleus is one of the most important parts in a cell. It is found right in the centre of the cell and has two major functions. 1-It stores the cells DNA. 2- It also organizes the cells activities, which consists of cell division, protein synthesis, intermediary metabolism and growth. Nucleolous- the primary role in the nucleus is ribosome biogenesis. Golgi Bodies- the Golgi Bodies distributes for any chemicals within the cell. Proteins and fats are modified which have been built in the endoplasmic reticulum and prepares them to get exported outside the cell. Ribosomes- Any living thing will contain ribosomes within the cell. They are made up of 60 percent RNA and 40 percent protein. Ribosomes are tiny organelles Lysosomes- (also called cell vesicles) round organelles surrounded by a membrane and containing digestive enzymes. This is where the digestion of cell nutrients takes place. Rough Endoplasmis Reticulum- membranous, infolded and convoluted sacks that are located in the cell's cytoplasm (the ER is continuous with the outer nuclear membrane). Rough ER is covered with ribosomes that give it a rough appearance. Rough ER transports materials through the cell and produces proteins in sacks called cisternae (which are sent to the Golgi body, or inserted into the cell membrane). Smooth Endoplasmis Reticulum- (smooth ER) a vast system of interconnected, membranous, infolded and convoluted tubes that are located in the cell's cytoplasm (the ER is continuous with the outer nuclear membrane). The space within the ER is called the ER lumen. Smooth ER transports materials through the cell. It contains enzymes and produces and digests lipids and membrane proteins, smooth ER buds off from rough ER, moving the newly-made proteins and lipids to the Golgi body, lysosomes, and membranes. Mitochondria- Mitochondria break down carbohydrate and sugar molecules to supply energy. They are oblong shaped organelles and found in the cytoplasm of eukaryotic cells. Microtubules- microtubules are also found in the cytoplasm of a eukaryotic ell. They are a hollow cylinder shape. Microtubules carry out many different functions such as transport and structural support. Cytoplasm- Most of the celluar activities happen in the cytoplasm. Such functions as growth, replication and cell expansion occur in the cytoplasm. Cytosol is a major part in the cytoplasm. It has enzymes which take molecules and break them down. This then allows individual organelles to use them when they need to. Plasma Membrane- a plasma membrane is found in all living cells. They regulate the passage of molecules in and out of cells. Plastids- the main function for a plastid is to store molecules. A certain type of molecule that plastids store is called pigment. This is when fruits and vegetables are orange or red when they ripen. Vacuole- every plant cell has only one large vacuole. It helps in plant growth. The vacuole also plays a very important structure for the plant. Chloroplasts- the chloroplast allows the important process of photosynthesis to occur. This is when the chloroplasts make their own food by turning light energy into chemical energy. How the plant cell works as a whole So you know the function of each organelle within the plant cell but what happens when one of the organelles don’t do its role? If there was one part of the plant cell that wasn’t functioning correctly then the whole cell wouldn’t perform to its full ability. Each of the organelles is connected in some way but yet they are not all joined together. For example the microtubules are connected to the cytoplasm which allows them to work together. If the microtubules weren’t working correctly then the rest of the cell would not be able to function correctly leaving the cell useless. Each part of the plant cell has its own role within in the plant cell and it’s responsible for making sure it does what it’s meant to. So therefore all of the organelles found within in the plant cell need to work together and work correctly to function to full ability.
