which meristematic tissue is found in root and shoot apex?
root
meristematic tissues contain cells that continue to grow and differentiate throughout the plant's lifetime. shoot apical meristem gives rise to flowers and leaves while root apical meristem grows into roots. these components are crucial to general plant growth and are the harbingers of development. meristematic tissue apparently contains characteristic epigenetic modifications. for example, the boundary between the proximal meristem and elongation zone showed elevated h4k5ac along with a high level of 5mc in barley. root meristematic tissues have been found to contain patterns for histone h4 lysine 5 acetylation, histone h3 lysine 4 and 9 di methylation and dna methylation as 5-methyl cytosine. so far, only a casual correlation between epigenetic marks and tissue types has been established and further study is required to understand the exact involvement of the marks (braszewska et al. 2013).
epigenetics of plant growth and development
permanent tissues may be defined as a group of living or dead cells formed by meristematic tissue and have lost their ability to divide and have permanently placed at fixed positions in the plant body. meristematic tissues that take up a specific role lose the ability to divide. this process of taking up a permanent shape, size and a function is called cellular differentiation. cells of meristematic tissue differentiate to form different types of permanent tissues. there are 3 types of permanent tissues:









































bullet::::1. simple permanent tissues









































bullet::::2. complex permanent tissues









































bullet::::3. special or secretory tissues (glandular).
