![]() ![]() It is bound by a cell wall and cell membrane which is inner to the cell wall It has a nucleus carrying the genetic material and cell organelles such as mitochondria, lysosomes, ribosomes, golgi apparatus, etc with varied functions. Note: Plant cell is rectangular with large vacuole occupying 30% of the cell volume. Early biologists saw cells as simple membranous sacs containing fluid and a few. Types of plastids are Leucoplast for storing protein, lipids, and starch and chloroplast for photosynthesis as it contains chlorophyll. Ideas about cell structure have changed considerably over the years. Plastids: They are membrane-bound and have their DNA. Vacuole: It is surrounded by tonoplast and the main function is Storage and maintenance of turgidity of the cell.į. Lysosomes: Membrane-bound organelle and their main function is the removal of worn-out organelles and other waste from the body.Į. Fungal cells and some protist cells also have cell walls. The cell wall is a rigid covering that protects the cell, provides structural support, and gives shape to the cell. Golgi apparatus: Packaging and transport of macromolecules to the other cells.ĭ. This book was prepared as lecture notes for biomedical laboratory sciences for undergraduate level. In Figure 1b, the diagram of a plant cell, you see a structure external to the plasma membrane called the cell wall. The main function of the nucleus is the storage of DNA.Ī.Mitochondria: It is a double membrane-bound organelle and is known as the powerhouse of the cell as it provides ATP.ī.Ribosomes Membrane-bound organelle and are protein factories of the cell.Ĭ. detailed diagram for use in education animal cell diagram stock illustrations. ![]() Vector illustration on a white background. ![]() The inside nucleus is the nucleolus and nuclear membrane. Plant cell and Animal cell structure Plant Cell and Animal cell structure. Nucleus: The nucleus is bound by a nuclear membrane perforated by a nuclear pore. The main function is to filter the movement of molecules across the cell.ģ. Inclusions: 6.1.6 Explain that computers have become invaluable in science because they. Cell Membrane: It is a semi-permeable layer present inside the cell wall. 6.4.6 Distinguish the main differences between plant and animal cells, such as the presence of chlorophyll and cell walls in plant cells and their absence in animal cells. It also guides the movement of molecules in and out of the cell.Ģ. The main function is to protect the cell and to provide structural support to the cell. Cell wall: It is the outermost layer made up of proteins, cellulose, and polysaccharides. ![]()
