Adaptations of vegetation. Conifers in the snow. 1  Coniferous trees have thick bark to protect against the cold. 2  They are cone-shaped, with flexible branches which help them to cope with heavy snow fall. 3  Pine cones protect the seeds during the harsh winter.
Yes-both plant and animal cells have a membrane-bound nucleus and organelles. The nuclear membrane controls the movement of molecules in and out of the nucleus.This is impo â¦ rtant for regulation and protection.onfidence votes 79. Nuclear membrane acts as a physical barrier, separating the nucleoplasm from the cytoplasm. It is a semipermeable membrane and allows transport of substances in and out of nucleus. Its inner membrane is involved in protein synthesis.
The Nuclear Envelope The nuclear envelope is a double-layered membrane that encloses the contents of the nucleus during most of the cell's lifecycle.The outer nuclear membrane is continuous with the membrane of the rough endoplasmic reticulum (ER), and like that structure, features numerous ribosomes attached to the surface.he other intermediate filament network is located on the outside of the outer nuclear membrane and is not organized in such a systemic way as the nuclear lamina. The amount of traffic that must pass through the nuclear envelope on a continuous basis in order for the eukaryotic cell to function properly is considerable.
