What is the function of cell cortex?A.Although actin is found throughout the cytoplasm of a eukaryotic cell, in many cells it is highly concentrated in a layer just beneath the plasma membrane. In this region, called the cell cortex, actin filaments are linked by actin-binding proteins into...
'Ectodesmata' are non-plasmatic structures (SCHNHERR and BUKOVAC, 1970a, b) and have, therefore, nothing in common with true plasmodesmata. There are many indications that plasmodesmata play a role in transcellular transport of substances and of stimuli, even if there is little direct proof ...

What are the parts inside a cell called? What plant cell structure is composed of cellulose and lignin? What gives a plant cell its rigid structure? What do the Golgi vesicles do in a plant cell? What is the semipermeable membrane in all cells?
Cells of the Male Reproductive System:The male reproductive system consists of organs which produce and nourish the male gametes required for an offspring to be produced. The males gametes are called sperm, which are produced in the testes. In addition to the production of sperm, certain ...
What is the main function of vacuole? A vacuole is a membrane-bound cell organelle. In animal cells, vacuoles are generally small andhelp sequester waste products. In plant cells, vacuoles help maintain water balance. Sometimes a single vacuole can take up most of the interior space of the ...
What is the function of the cell wall in an onion cell? Building Blocks Of Living Organisms: Cells are the fundamental building blocks of all living things, including plants. Plant cells are eukaryotic, which means that they are complex with many structures and organelles that keep them alive ...
The function of the cell membrane almost does not exist during osmosis as well. Osmosis is the movement of water in and out of a cell. This water movement happens naturally to try and balance the solution concentration of the water. If there are too many solutes such as proteins in a sol...
Nucleoids are thin, transparent areas of prokaryotic cells that contain DNA. Some DNA is contained in other areas of the cell as well, depending on the organism, but the nucleoid is the primary center for DNA transcription and replication. Prokaryotes do not have a membrane-bound, defined nucl...
The function of the circulatory system is to deliver nutrients to the cells of the body using blood and to regulate the body's...
