(a) Explain the composition of a plant cell wall. (b) How it differs from the cell wall of a prokaryotic cell? How do cells in a meristem differ from cells in other types of plant tissue? What is the difference
It is simplest to make the basic form of the plant cell first, including the cell wall, cell membrane and cytoplasm. The cell wall is an impermeable layer that surrounds the outside of the cell, giving it protection and support. It should have tiny openings or pores throughout called plasm...
Phosphorylated YAP can be sequestered in the cytoplasm and then degraded by the ubiquitin–proteasome system, whereas unphosphorylated YAP translocates to the nucleus, where it performs a series of functions. YAP and its paralogue, transcriptional co-activator with PDZ-binding motif (TAZ), are the ...
How do mitochondria import proteins from the cytoplasm into the matrix? Mitochondria is thought to have been developed from: a. Cyanobacteria b. Gram-positive bacteria c. Plasmid d. None of the above What three facts about mitochondria have led most scientists to believe that they r...
One difference between cell division in plants and animals is that plant cells form a cell wall after mitosis to separate the nuclei and cytoplasm of the two new identical cells. After animal cells undergo mitosis, the cell membrane pinches together alon
It pretty much has the same job as the skin but better protects the internal organs and the brain is the 2nd to last layer of the cell and holds the body into shape. The cell also features a cytoplasm, or in this case blood, because blood is all around the body and they are both ...
Figure 2. FtsZ proteins assemble to form a Z ring that is anchored to the plasma membrane. The Z ring pinches the cell envelope to separate the cytoplasm of the new cells. Think about It What is the name of the protein that assembles into a Z ring to initiate cytokinesis and cell divi...
Pressure gradients within the cell also have a role during cell growth, by moving cytoplasm towards the growing tip. Essentially, mass flow operates in a microfluidics environment that encompasses the mycelial network. This is separate from the intracellular transport that is mediated by the cytoskelet...
Streptococcus suis is a zoonotic agent that causes sepsis and meningitis in pigs and humans. S. suis infections are responsible for large economic losses in pig production. The lack of effective vaccines to prevent the disease has promoted the extensive
Microorganisms can accumulate PHA up to 97% of cell dry weight (CDW) (Muhammadi et al., 2015) in their cytoplasm and use it as energy storage. Surplus quantities of carbon source with limitation of other crucial nutrients e.g. nitrogen or phosphorous and sometimes with pH shifts are the ...
