Answer:
1) manufactures ribosomes : Ribosomes are mainly found bound to the endoplasmic reticulum and the nuclear envelope, as well as freely scattered throughout the cytoplasm, depending upon whether the cell is plant, animal, or bacteria. The organelles serve as the protein production machinery for the cell and are consequently most abundant in cells that are active in protein synthesis, such as pancreas and brain cells. Some of the proteins synthesized by ribosomes are for the cell's own internal use, especially those that are produced by free ribosomes. Many of the proteins produced by bound ribosomes, however, are transported outside of the cell.
In eukaryotes, the rRNA in ribosomes is organized into four strands, and in prokaryotes, three strands. Eukaryote ribosomes are produced and assembled in the nucleolus. Ribosomal proteins enter the nucleolus and combine with the four rRNA strands to create the two ribosomal subunits (one small and one large) that will make up the completed ribosome (see Figure 1). The ribosome units leave the nucleus through the nuclear pores and unite once in the cytoplasm for the purpose of protein synthesis. When protein production is not being carried out, the two subunits of a ribosome are separated.
2) carrys out photosynthesis : Most, if not all, the creatures on Earth rely on photosynthesis in one way or another. This places extra importance on the major photosynthesizing organisms, plants, algae and specialized bacteria, but members of the family Animalia have also adapted to use the process. These species, called autotrophs, take in water, carbon dioxide and the light from the sun and use it to create a simple sugar for their own use. The process releases sugar, oxygen and water.
Species like plants, the most famous autotrophs, create the compounds necessary for cellular respiration, a process carried out by heterotrophs, such as humans, who breathe in the oxygen released by the plants and, in turn, exhale carbon dioxide. Humans and many other animals also eat plants and algae to absorb the sugar they create. This relationship between heterotrophs and autotrophs drives life on Earth.
3) can bud of vehicles ,which form the golgi apparatus : Vesicles
4) manufacture ATP in animal and plant cells : Mitochondria and chloroplasts represent endosymbiont models of complex organelle development driven by evolutionary modification of permanently enslaved primordial bacteria . Over diverse eukaryotic phyla mitochondria and chloroplasts either alone or together provide a concerted amplification of cellular energy production via shared biochemical pathways. Cellular dysregulation of these two distinct organelles may generate potentially dangerous reactive oxygen species (ROS) due to compromised complex bioenergetics energy production, systemic oxidative stress and compounded pro-inflammatory processes. Importantly, genetically- or biochemically-mediated failure of mitochondrial function in human populations represents a potentially dire factor in the etiology of major disease states that include Type II diabetes, atherosclerosis, rheumatoid arthritis, Alzheimer’s Disease, and cancer progression . In sum, these compelling mechanistic and clinical data suggest that the extent of mitochondrial/chloroplast regulatory signaling may vary over the lifetime of the eukaryotic cell according to physiological demand and bioenergetics requirements .
Interestingly, a tumor cell may be viewed as a phenotypic reversion to the last common eukaryotic ancestor of the host cell, i.e., a facultative anaerobic microbe with unlimited replication potential . For example, anaerobic mitochondria in gill cilia of M. edulis have evolved to utilize the phenotype of a facultative anaerobe, demonstrating that this primitive type of respiration has been evolutionarily conserved . Accordingly, anaerobically functioning mitochondria may represent a re-emergence or evolutionary retrofit of primordial metabolic processes.
A selectively permeable membrane chooses which molecules are allowed to pass based on specific criteria (e.g., molecular geometry). This facilitated or active transport may require energy.
5) seletevelly permeable : Semipermeability can apply to both natural and synthetic materials. In addition to membranes, fibers may also be semipermeable. While selective permeability generally refers to polymers, other materials may be considered to be semipermeable. For example, a window screen is a semipermeable barrier that permits the flow of air but limits the transit of insects.
