Cellular modification

Cards (10)

  • Cellular modifications are specialized processes or modifications re-acquired by the cell after cell division where the newly formed cells are structurally modified so they can perform their function efficiently and effectively.
  • Microvilli is a plasma membrane cell that increases the surface area of eukaryotic cells. It is characterized by folded fingerlike projections and has a dense bundle of cross-linked actin filaments which serves as its structural core
  • Cilia are tail like projections found in eukaryotic cells. It helps in preventing accumulation of dust in breathing tubes by creating a thin layer of mucous along tubes.
  • Motile cilia are used to move cells throughout certain parts of the organisms
  • non-motile cilia are usually found in the eyes and the nose to trap dirt and other objects.
  • Stereo cilia are different from cilia they are more closely related to microvilli.
    It has distinctive characteristics, their length and lack of motility. --are basically an apical modification of the cell.
    -are mechano-sensing organelles of hair cells
  • Muscle is for contraction and when this contraction is coordinated, it results in movement. The muscle cell is generally elongated and elastic containing mitochondria in large number.
  • root hair cells are modified epidermal cells of the roots. These are tubular extensions of individual epidermal cells which can be found in a zone just behind the tips of young, growing roots.
  • Trichomes are cellular or multicellular hair-like outgrowths of the epidermis. They occur frequently on stems, leaves, and reproductive organs.
  • guard cells which are paired, sausage shape cell flanking stoma, a mouth-shaped epidermal opening. Guard cells, unlike other epidermal cells, contain chloroplast.
