Eukaryotic Cell Structure

Plant cells are unique among the eukaryotes (Greek for “true kernel”) (Origins. 2009) organisms whose cells have membrane-enclosed nuclei and organelles, because they can manufacture their own nutrients.

Like the fungi, another kingdom of eukaryotes, plant cells have retained the protective cell wall structure of their prokaryotic ancestors. The basic plant cell shares a similar construction with the typical eukaryote cell, but does not have centrioles, lysosomes, intermediate filaments, cilia, or flagella, as does the animal cell. Plant cells do, however, have specialized structures, including a rigid cell wall, central vacuole, plasmodesmata, and chloroplasts. Although plant cells (and their typical cells) are non-motile, some species produce gametes that do exhibit flagella and are thus able to move about (Plant Cell Structure. 2009).

Two of the essential structures or organelles of plant cells are: a) Microtubules are the straight, hollow cylinders are found throughout the cytoplasm of all eukaryotic cells and carry out a variety of functions, rang...

    Firstly, the cytoskeleton, (made up of microtubules and microfilaments), moves the organelles around giving them shape. The plant cells have cell walls and cytoskeletons. The animal cell does not have cell walls. The cytoskeleton gives the cell a structure and a shape. It also gives the cell locomotion. The cytoskeleton base is attached to the cell membrane, so the cell membrane plays a role of helping a cell maintain its structure. Secondly, the cytoplasm also aides the cell for structure. The cytoplasm surrounds the whole cell. This in turn helps support the cell by keeping all the organelles in place. The cell would be empty and deflated if their was no cytoplasm, so it takes a huge role for maintains the cell's shape and structure. Last but not least, the plant cells! The plant cells has cell walls that maintains its structure. Although, plant cells have cytoskeletons they have cell walls too. The cell wall is a rigid, tough, or a flexible barrier. They support the plant cell from physical stress, so it can maintain its structure. In brief, cells have a ton of ways to sustain structure and

    By definition, a cell is life's basic unit. In practice, the cells share several mechanisms across different animals, plants, and microorganisms. Two fundamental differences exist between the architecture of cells for different classes of organisms (Jan, 2014). Lipids build and maintain both the plasma (the external bilayer) and the nuclear membrane within a cell. In addition, the thick filament of proteins (actin filaments and microtubes) confer rigidity to the cytoskeleton of the cell. Factors, such as physical forces acting on a cell as and the cell’s mechanical environment control gene regulation (the rate of production of proteins). In animals, the polymer filament gel (network) regulate the motility of cells. In fact, forces acting on the polymer gel tend to deform the cell membrane.

Cell walls, along with cellulose, provide support for plants so that they can grow tall while maintaining their shape. The size of the plant will determine the amount of cellulose it will need, but all plants require some amount of it and make use of it constantly.

In general, plant cells differ from animal cells in that they have a rigid cell wall exterior to the plasma membrane; a large vacuole, or fluid-filled pouch; and chloroplasts that convert light energy to chemical energy for the synthesis of glucose.

    This organelle is the site of photosynthesis in plants and other organisms. In the structure, the chloroplasts has a double membrane, the outer membrane has a continuous boundary. This organelle can be found in a vast group of organelles called the plastid, chloroplasts are usually found in many plant cells but never in animal cells. Chloroplasts organelles are large; they are 4-10um long and 2-3um wide. They are very important to plants because chloroplasts are what plants use to create food from sunlight. Chloroplasts are not found in humans.

    The Animal Cell is a little bit different than the Plant Cell for only a couple of reasons. One is how the Plant Cell has a cell wall and the Animal Cell doesn’t. The cell wall protects and gives structure to the cell. Then there is the Nucleus, which serves as a control center for the cell. Inside the Nucleus there are one or more Nucleoli. They are dense, granular bodies that disappear at the beginning of cell division and reappear at the end. Then you have the Cytoplasm. This is the watery material lying within the cell between the cell membrane and the nucleus. The Cytoplasm also contains organelles, which have specific functions in the cell metabolism. Then there are the Golgi Bodies, which serve as processing, packaging, and storage for the cell. These organelles package and ship things out. Another parts of the cell, a very important one in fact, are the Lysosomes. These organelles are used to break things down and contain enzymes.

  • Essay On Plant Nutrition

    1635 Words  | 4 Pages

    Plant nutrition is area of plant biology that is of the utmost importance for the proliferation of plants. Without proper nutrition, plants would simply cease to exist unless drastic alterations were made. There are certain elements that are required for the plant to grow and reproduce; these elements are known as essential elements. There are three requirements of an essential element: the element must be required for the completion of the plant’s life cycle, the element must not be replaceable by another element in whole, and finally the element must be direction involved in the metabolism of the plant. Chemical compounds that are involved in proper nutrition have been designated as nutrients, and further classified as macronutrients and micronutrients. Macronutrients are needed for growth, metabolism, and many other functions, but are designated as “macro” because they are required in larger amounts. Macronutrients include carbohydrates, proteins, and fat molecules. Micronutrients have a much wider function that depends on the exact micronutrient. Micronutrients are designated as so because they are needed in much smaller amounts when compared to macronutrients. Examples of micronutrients include vitamins and minerals.
