(smooth). Ribosomes – This binds to the rough endoplasmic reticulum and to the mRNA. It also enables translation of mRNA to produce proteins. Golgi apparatus – Receives proteins from the ribosomes via endoplasmic reticulum and chemically modifies them for export (particularly in secreting cells). Produces vesicles to transport the modified proteins to the cell membrane for release. It receives and modifies lipids from the smooth endoplasmic reticulum for transport to the cell membrane. It also produces

The rough endoplasmic reticulum transports things throughout the cell‚ and the smooth endoplasmic reticulum in a branch of the rough endoplasmic reticulum. These organelles can be compared to the transportation system such as a subway station because they both transport things. The flagella is what helps the cell move as a whole. This

Eukaryotes have organelles because it has to carry out so many complicated activities to do in the body. One example of an organelle is the endoplasmic reticulum. The ER is a series of membranes extending throughout the cytoplasm of eukaryotic cells. The rough endoplasmic reticulum has ribosomes. The rough ER is the location of protein synthesis in a cell because it contains ribosomes however; the smooth ER lacks ribosomes and is responsible for producing lipids

by the ribosome’s into proteins. When a certain function is needed in the cell‚ cellular signals (proteins‚ hormones‚ etc) will activate transcription‚ leading to the production of proteins that will perform the necessary function. The Endoplasmic Reticulum is like the cell ’s passage way; the Golgi apparatus package and tag protein products so that they safely get where they need to go. Secretor vesicles only exist transiently in the cell and are part of the end membrane system that shuttle

1. Describe the structure of a generalized eukaryotic plant cell. Indicate the ways in which a nonphotosynthetic prokaryotic cell would differ in structure from this generalized eukaryotic plant cell. Plants are unique among the eukaryotes. The interiors of plant cells‚ like all eukaryotic cells‚ contain numerous organelles‚ which are membrane bounded structures that close off compartments within which multiple biochemical processes can proceed simultaneously and independently. The cell membrane
