Plants cells have DNA that helps in making new cells, hence enhancing the growth of the plant. the DNA is enclosed within the nucleus, an enveloped membrane structure at the center of the cell. The plant cell also has several cell organelle structures performing a variety of functions to main...
One of the most important parts of the cell is the cell membrane. The cell membrane acts as a semi-permeable barrier. It allows only a few molecules across it and fences the majority of organically produced chemicals inside the cell. The primary components of the cell are – cell membrane,...

Like plant cells, animal cells have a cell membrane. This is an important barrier that separates the interior parts of the cell from the external environment while also regulating the movement of molecules/substances in and out of the cell. In both plants and animals, the cell membrane is a ...
A brief review of current data on the molecular biology of stem cells forming meristems and differentiating into various organs of angiosperms is presented. Different primary and secondary meristems are compared. The interactions of some hormones, regulatory gene networks, and signaling pathways in dif...

Plant Cell Division: Methods and Protocols captures basic experimental protocols that are commonly used to study plant cell division processes, as well as more innovative procedures. Chapters are split into five parts covering several different aspect of plant cell division such as, cell cultures for...
Below is a list of the main parts shown in the plant cell diagram and the roles that they play in the cell. Nucleus- contains the genetic information of the cell. Nuclear envelope- double membrane surrounding the nucleus. Perinuclear space- space between the two membranes of the nuclear envel...
1.2.1 A Unique Plant Constituent: Cellulose and the Cell Wall Identification of plant food cells from human digestive tracts requires knowledge of the shapes and sizes of these cells as well as how they may appear together in plant fragments. Seed plant cells, as well as many cells of the ...
