The top section is a cross-sectional view with bordered pits shown between adjacent cells, and the bottom section is a radial view with numerous bordered pits shown. Pits are relatively thinner portions of the cell wall that adjacent cells can communicate or exchange fluid through. Pits are characteristic of cell walls with secondary layers ...
Contributions to the understanding of the fine structure of the wood cell wall were also made by Albert Frey-Wyssling and Reginald Dawson Preston, who employed light microscopy-based techniques. In parallel, Johannes Liese integrated his expertise in wood anatomy and decay mechanisms with extensive studies on wood protection. [21]
The cytoplasm describes all the material within a eukaryotic or prokaryotic cell, enclosed by the cell membrane, including the organelles [1] and excluding the nucleus in eukaryotic cells. The material inside the nucleus of a eukaryotic cell and contained within the nuclear membrane is termed the nucleoplasm .
InsideWood is an online resource and database for wood anatomy, serving as a reference, research, and teaching tool. Wood anatomy is a sub-area within the discipline of wood science. [1] [2] This freely accessible database is purely scientific and noncommercial.
A dendrite (from Greek δένδρον déndron, "tree") or dendron is a branched cytoplasmic process that extends from a nerve cell that propagates the electrochemical stimulation received from other neural cells to the cell body, or soma, of the neuron from which the dendrites project.
The centrosome is copied only once per cell cycle, so that each daughter cell inherits one centrosome, containing two structures called centrioles. The centrosome replicates during the S phase of the cell cycle. During the prophase in the process of cell division called mitosis, the centrosomes migrate to opposite poles of the cell. The mitotic ...

Some eukaryotic cells (plant cells and fungal cells) also have a cell wall. Inside the cell is the cytoplasmic region that contains the genome (DNA), ribosomes and various sorts of inclusions. [2] The genetic material is freely found in the cytoplasm. Prokaryotes can carry extrachromosomal DNA elements called plasmids, which are usually circular.
