Threadlike structure found in the nucleus. They help in the uptake of minerals and water. This vacuole is so large that it displaces the cell organelles to the periphery, and the cell seems to have only a thin layer of cytoplasm surrounding it. Cell specialization, also known as cell differentiation, is the process by which generic cells change into specific cells meant to do certain tasks within the body. Specialized Plant Cell Types: All plant cells are characterized by several common features, such as chloroplasts, a cell wall, and a large vacuole. This gene is responsible for the production of Testis Determining Factor (TDF), which later influences the formation of the male sex organ. In adults, stem cells are specialized to replace cells that are worn out in the bone marrow, brain, heart and blood. Animals and plants have cells that are specialized by the process of differentiation. Single-unit muscle fibers are compactly packed together, while multi-unit muscle fibers are more loosely packed and usually intertwined with connective tissues. Cell specialization means that the cells in an organism are uniquely suited to reproduce. Directions: Click on each plus sign to learn more about these specialized cells. Again, these are specialized epithelial cells that are present on the root. Groups of special-pecialized cells perform specialized functions in multicellular organisms. Animal cells and plant cells are similar in that they are both eukaryotic cells.These cells have a true nucleus, which houses DNA and is separated from other cellular structures by a nuclear membrane. In addition to having a nucleus, plant cells also contain other membrane-bound organelles (tiny cellular structures) that carry out specific functions necessary for normal cellular operation. Xylem and Phloem cells are used by the plant to transport minerals, sugar and water to other parts of the plant. As an organism grows, its cells become specialized to perform specific functions. Animal and plant cells have certain structures in common. Collenchyma cells.

These are specialized epithelial cells that are present on the leaves and stems. dry onions). Mature sperm cells are haploid and motile, which fertilize the matured female reproductive cells, i.e., the ova, to produce a zygote. This is done by cell division, i.e. This worksheet covers the concepts of differentiation, specialisation, and adaptations in both animals and plants. Every organism is made of organ systems, every organ system has a few organs comprising it, every organ is made of tissues performing a particular function, and every tissue is made of a group of specialized cells. You can see many of the modifications in common garden and edible plants. The process of cell specialization – exactly how cells develop into their diverse forms – is complex. In flowering plants, pollen formation depends on the differentiation and interaction of two cell types in the anther: the reproductive cells, called microsporocytes, and somatic cells that form the tapetum. In addition, there is a number of specialized types of plant cells that are found only in vascular plants.
