      • A model of a typical plant cell is found to be rectangular in shape, ranging in size from 10 to 100 µm. Under the microscope, it shows many different parts. Each part, known as an organelle, works together to keep the cell functional.

    It is the outermost, protective layer of a plant cell having a thickness of 20-80 nm. Cell walls are made up of carbohydrates such as cellulose, hemicellulose, and pectin and a complex organic polymer called lignin.

    They are double membrane-bound organelles that have their own genetic material. Plastidsare mainly of three types: a) Chloroplasts: Found in the green parts of a plantand algae that contain the photosynthetic pigment, chlorophyll. b) Leucoplasts: Found in the non-photosynthetic tissues of plants. c) Chromoplasts: Colored plastics found in fruits an...

    It is the large vesicle that make up almost 30 to 80% of the total plant cell volume. The central vacuoleis often the largest organelle in the cell that is filled with fluid, ions, enzymes, and other molecules. Apart from plants, they are also present in algae.

    It is a thin, biological membrane having a thickness of 7.5-10 nm that separates the interior of the cell from the outside environment. The plasma membrane is selectively permeable in nature, which is mainly composed of lipids and proteins, with some carbohydrates attached to them.

    It is a series of membranes within the cytoplasm that forms connections with the nucleus on one side and cell membrane on the other. It is of two types: rough endoplasmic reticulum (RER) and smooth endoplasmic reticulum (SER). The surface of RER has ribosomesattached to it, while they are absent in SER.

    Also known as Golgi body or Golgi complex, they are stacks of five to eight membrane-covered sacs called cisternae. The Golgi apparatus acts as the post office of the cell by packaging and transporting proteins from their source RER to their destination.The number of Golgi apparatus varies in cells according to their functions.

    They are a network of long and thin protein fibers present in the cytoplasm of the cell having a diameter of 3-6 nm. Microfilamentsare composed of actin proteins that make them extremely strong and flexible.

    They are fibrous hollow rods composed of proteins called tubulin. Microtubuleshave an outer diameter of 23-27 nm and an inner diameter of about 11-15 nm. They can grow to as long as 50 µm and thus are highly dynamic.

    They are made up of two proteins forming a coiled-coil structure. Intermediate filaments have a diameter of 8-10 nm that are intermediate in size to microfilaments and microtubules. Microtubules, together with microfilaments and intermediate filaments, form the cytoskeletonof the cell.

    It is a rod-shaped double membrane-bound organelle that contains its own DNA and ribosomes. Mitochondria are often called the ‘powerhouse of the cell‘, producing ATP that drives all cell-based metabolic activities.

  5. The electrons that have passed through the specimen are collected by an electron detector attached to a digital camera. An example is shown in Figure 01-08, where some of the subcellular structures in a plant cell have been labeled for you.

  6. Mar 7, 2024 · The most common specimens to observe under a light microscope are cheek cells (animal cells) and onion cells (plant cells) A stain is often used to ensure cell structures are clearly visible under the microscope.

  7. Jan 18, 2024 · These structures can be found on the image of the plant cell (Figure \(\PageIndex{1}\)). Figure \(\PageIndex{1}\)): This figure show the major organelles and other cell components of a typical eukaryotic plant cell. The plant cell has a cell wall, chloroplasts, plastids, and a central vacuole—structures not in animal cells.
