Comparing a leaf palisade cell and liver cell

The leaf palisade cell contains a number of different organelles, which do different things in the cell, all of which are necessary to the survival of the plant.

The entire cell is held together by a cell wall. The cell wall is only found in plants to keep it sturdy and has no need to pass matter from one cell to another.

The cell also contains cytoplasm. This is a material found between the cell membrane and the nuclear envelope. Fibrous proteins that occur in the cytoplasm, maintain the shape of the cell as well as anchoring organelles, moving the cell and controlling internal movement of structures.

Among the cytoplasm are chloroplasts, chloroplast contain many different types of accessory pigment depending on the type of organism being observed. In this case the pigment is green. The chloroplasts contain their own DNA making the cell what it is. The chloroplasts are important in the leaf as they contain chlorophyll, which are necessary for photosynthesis. Chloroplasts are never found in animal cells, as they are not needed.
        In the middle of the palisade cell is the vacuole. The vacuole is a fluid filled sac bounded by a single membrane surrounded by a tonoplast. The fluid inside is called cell sap. Vacuoles play roles in digestion and in the release or cellular waste product. The vacuole helps to keep the cell clean. The tonoplast acts like a membrane and keeps the cell sap in.
        A nucleus is found in every eukaryotic cell. It controls the shape and features of the cell. The cell membrane functions as a semi-permeable barrier, allowing very few molecules across it while fencing the majority or organically produced chemicals in the cell.
        All of these structures work together to help the leaf photosynthesis. This means it can capture the suns energy and turn it into food for the plant.
        The liver cell contains some of the same materials as the leaf palisade cell, but not all. The liver cell contains the rough endoplasmic reticulum, which is a mesh of interconnected membranes that serve a function in protein synthesis and transport. Rough ER is so-named due to its rough appearance formed by numerous ribosomes that occur along the ER. The rough ER connects to the nuclear envelope through which the messenger RNA (the blueprint for proteins) travels to the ribosomes.
        Mitochondria contain their own DNA and are thought to represent bacteria like organisms incorporated into eukaryotic cells over 700 million years ago to 1.5 billion years ago. The mitochondrion has been termed the powerhouse of the cell and is banded by two membranes.
        All cells contain a nucleus and a nuclear envelope and the liver cell is no exception. It has exactly the same control over the cell as the palisade nucleus does. To keep it all together, it is surrounded by a cell membrane. This semi-permeable matter allows information to be spread from cell to cell.
        The liver cell also has a golgi apparatus, which is a network of stacked sacs found within nucleated cells that store, package and distribute the proteins and lipids made in the rough ER. Proteins that are meant to return to the ER carry a distinctive tag. The golgi apparatus recognises the tag and transports the proteins back to the ER.
