Cork is a collection of dead cells that replaces the epidermis in woody stems. B.Meristematic cells divide into two cells, one of which remains a meristem cell and another that becomes a plant body cell. Plants use lateral meristem tissue to grow in diameter as part of secondary growth. Cambium is layer or layers of tissue, also known as lateral meristems, that are the source of cells for secondary growth. Intra means within.

Definition noun, plural: cork cambiums or cork cambia A meristematic tissue that divides mitotically to give rise to new cells that form the cork (phellem) and the phelloderm Supplement A cork cambium is a type of meristematic tissue in many vascular plants. The cork cambium, which gives rise to the periderm, is an example of a lateral meristem. B. lateral meristems. The cells are closely packed and as such intercellular spaces between cells are absent. The cork cambium also is a secondary meristem, containing meristematic cells. Other articles where Cork cambium is discussed: tissue: Plants: …the vascular cambium and the cork cambium.

Cork cambium or phellogen (develops from pericycle during periderm formation), inter fascicular cambium of dicot stem (develop from medullary rays), wound cambium (from surrounding cells of injuries), accessory cambium (cambium of moncots like Dracaena, Yucca) and cambium of roots are secondary meristems. A very simple answer is that ‘meristem’ is the general term for the growth areas of plants - and that cambium is one particular type of meristem.

The meristems that originate from permanent cells by dedifferentiation are called the secondary meristems. Due to the cambial ring activity, the outer layers such as cortex cells and epidermis get crushed. The cork cambium produces cork cells which combine with phloem to form bark. A. Sometimes, the two terms are used interchangeably since both of them are concerned with increase in thickness rather than in length (as in primary meristem). Vascular cambium and cork cambium are the examples of . meristems experience the pull of gravity directly. NCERT RD Sharma Cengage KC Sinha. Cork is a specialized secondary tissue produced by the cork cambium of the plant (see meristem, bark). cork cambium and accessory cambia). They produce secondary tissues from a ring of vascular cambium in stems and roots. Meristem, region of cells capable of division and growth in plants.Meristems are classified by their location in the plant as apical (located at root and shoot tips), lateral (in the vascular and cork cambia), and intercalary (at internodes, or stem regions between the places at which leaves attach, and leaf bases, especially of certain monocotyledons—e.g., grasses). Cork Cambium. In roots, the procambium can also give rise to the pericycle, which produces lateral roots in eudicots. The vascular cambium produces secondary xylem and phloem which form rings of tissue. An example of a secondary meristem is the lateral meristem (e.g. The cork cambium forms a major portion of the bark of woody plants. D. Which of the following is not true about meristems?
