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 nucleus is an organelle that is surrounded by a double membrane called the nuclear envelope. The nuclear envelope separates the contents of the nucleus from the rest of the cell. Eukaryotic cells also have a cell membrane (plasma membrane), cytoplasm, cytoskeleton, and various cellular organelles.nlike eukaryotic cells, prokaryotic cells do not contain membrane-bound organelles. However, they do contain some non-membranous organelles such as ribosomes, flagella, and plasmids (circular DNA structures that are not involved in reproduction). Examples of prokaryotic cells include bacteria and archaeans.
