Water your Norfolk Island pine when the top of the soil feels dry to the touch. Fertilize your Norfolk pine in the spring and summer with a water soluble balanced fertilizer, but you do not need to fertilize in the fall or winter. It is normal for Norfolk Island pine trees to have some browning on the bottom branches.irst thing to keep in mind with the care of Norfolk pines is that they are not cold hardy. They are a tropical plant and cannot tolerate temperatures below 35 F. (1 C.). For many parts of the country, the Norfolk Island pine tree cannot be planted outside year round. It also needs to be kept away from cold drafts.
Microfilaments (or actin filaments) are the thinnest filaments of the cytoskeleton found in the cytoplasm of all eukaryotic cells. These linear polymers of actin subunits are flexible and relatively strong, resisting buckling by multi-piconewton compressive forces and filament fracture by nanonewton tensile forces.
Intermediate filaments. Intermediate filaments. cytoplasmic filaments intermediate in diameter (about 10 nanometers) between the microfilaments and the microtubules. They may be composed of any of a number of different proteins and form a ring around the cell nucleus.
