cell cmmunication: r eceptor proteins in the plasma membrane enable the cell to receive signals from the environment.;import and export of molecules: channels and transporters in the membrane enable the import and export of small molecules selectively.;cell growth and motility : the flexibility ...
What is the function of cutaneous membrane? (a) Define somatostatin. (b) What is its function? Describe the function of the glenoid labrum. (a) Define epiploic appendages. (b) What is its function? What is the function of the plasma membrane?
What is the function of cerebrospinal fluid? Cerebrospinal Fluid: The brain and spinal cord are the two structures of the central nervous system. Both of these structures are surrounded by the meninges, which are three layers of membrane that protect them. The meninges include the dura, arachnoid...
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...
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 Golgi apparatus function? The Golgi apparatus, or Golgi complex, functions asa factory in which proteins received from the ER are further processed and sorted for transport to their eventual destinations: lysosomes, the plasma membrane, or secretion. In addition, as noted earlier, glyc...
The nucleoid is the region of the cell that contains primary DNA material, which includes several proteins and enzymes that transcribe DNA and RNA and assist with cell growth and development.Nucleoids are components of unicellular organisms classified as prokaryotes. Along with a plasma membrane and...
4.3. When does sperm production start in the male? 4.4. How far does a human sperm cell travel to fertilize an egg? 4.5. How fast can a sperm travel? 4.6. Why does the human sperm cell have lots of mitochondria? 4.7. What is the function of the head of the sperm? 4.8. What is...
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 ...
When I took biology I was totally fascinated by the plasma membrane. It really is integral to the cells functioning because of the way it allows some things, but not others, to pass through the membrane. There are also membranes inside the cell. In fact, the compartmentalization inside the ...
