Plasmodesma (plural: plasmodesmata) is thin irregular cylinder of cytoplasm lined by plasmalemma, passing through fine pores in the cell walls, thus forming a connection between the cytoplasm of adjacent cells. They are found in higher plants and fluctuate widely in abundance and distribution. They are commonly present in primary pit fields and pit membranes of young and mature living cells [...]
In this article we will discuss about the Quiescent Centre (QC) found in root-promeristem of higher plants. It is observed that in the root-promeristem of higher plants the initials divide much less frequently than other cells. This part of root-promeristem, which contains the initials of epidermis, cortex and stele and divides less frequently, is referred to as quiescent centre (QC). [...]
In this article we will discuss about the structure of epidermis in plants. This will also help you to draw the structure and diagram of epidermis in plants. The outermost layer or layers of cell covering all plant organs are the epidermis. It is in direct contact with the environment and so it modifies itself to cope up with the [...]
