Plastid

Cercoza - Paulinella chromatophora The spectacle of endosymbiosis is the ability of one organism to live within another, changing and influencing the evolution of life, and shaping the ecology of countless species. Endosymbionts and their hosts typically represent distinct domains of life. The origin of primary plastid is traced back to a single primary endosymbiosis where a non-photosynthetic protist engulfs a photosynthetic cyanobacteria as cytoplasmic organelles. Plastids and the mitochondria are organelles in eukaryotic cells that derived from bacterial endosymbionts through the invasion and enslavement of synergistic amalgamation. The descendants of the primitive photosynthetic eukaryotes made way for the rise of green, red, and glaucophyte…

Plastids, is not the correct answer. Plastids are one of the plant organelles (Campbell, pg. 111). Different plastids have different color. Chloroplast is a green plastids while amyplast is a colorless plastids (Campbell, pg. 111; Citovsky, Lecture 10). The major function of plastids is storage of starch (Campbell, pg. 70). Since the major function of plastids is not about movement of cells, Choice C is not a correct answer. Choice D. Centrioles, is the correct answer. Centrioles are usually…

arenicola is also facilitated by the remarkable growth of the plastid that results in it occupying most of the symbiont compartment, shown in (E). The increased surfaced area of the plastid benefits the host because more receives more energy to power its activities. H. arenicola is said to be in its plant stage because it is receiving energy from its photosynthesizing symbiont. The “Half-plant, Half-predator” model helps describe how H. arenicola’s life cycle accommodates its baffling…

Sea slugs and aquatic plants have similar core features that allow both of them to acquire energy from light, but the sea slugs mechanism is far more involved and revolved around evolution. Elysia chlorotica, or the sea slug, have acquired the ability to conduct photosynthesis in their adult stages of life through their consumption of Vaucheria litorea. Vaucheria litorea are algae that are the primary diet of the developed sea slugs. Juvenile slugs acquire this ability when they ingest the algae…

When the potato cells were scraped off of the surface, the structure was disturbed, resulting in the oddly shaped cells observed. Iodine, a starch indicator, was added, resulting in a purple colored amyloplasts, where the cell’s starch is stored. No other structures were stained intensely because of the condensed location of the starch in the cell. Amyloplasts, like chloroplasts, are a type of plastid. Since other plastids were difficult to view, a conclusion on the comparative qualities of…

The Cell Membrane is one of the most important parts of the cell. If not for the cell membrane it would be extremely easy for things to invade the cell; this is because on of the cell membranes job is to control what come in and out of the cell (i.e. ions, viruses, etc). Also the cell membrane is what helps hold the cell and all of its organelles Endoplasmic Reticulum (AKA the ER), smooth and rough whats the difference? The smooth ER does not have any ribosomes while the rough ER is covered in…

also contain other membrane-bound organelles, or tiny cellular structures, that carry out specific functions necessary for normal cellular operation. Organelles have a wide range of responsibilities that include everything from producing hormones and enzymes to providing energy for a plant cell. Plant cells are similar to animal cells in that they are both eukaryotic cells and have similar organelles. Plant cells are generally larger than animal cells. While animal cells come in various sizes…

membrane-bound organelles. These organelles are accountable for constructing hormones and enzymes that deliver energy for a plant cell. An animal cell is as well a eukaryotic cell that has a nucleus and organelles. Animal and plant cells are very similar, but they are also very opposite at the same time. A plant cell is commonly bigger than animal cell. The normal range of animal cell is from 10 to 30 micrometers and a plant cell stretches from 10 to 100 micrometers. Animal cells come in…

flagella, cilia, nucleus, nuclear membrane, nucleolus, chloroplast, Golgi apparatus, lysosomes, mitochondria, plastid, rough endoplasmic reticulum, smooth endoplasmic reticulum, vacuole, and a vesicle. Everyday items can represent many of the organelles. One example of this is by looking at a house. In a house you have a fence. The fence in your house would represent a cell membrane in the house. The cell membrane is the outer covering made lipid bilayer. The main function for it is to be a…

the cell needs to survive. In plant cells there is one large vacuole, whereas in animal cells that are multiple small vacuoles. The nucleu is the 'brain' of the cell and contains the DNA of the cell and the chromosomes of the cell. It has the cell 'instructions' and uses them in protein production and cell division. It is contained by the nuclear membrane. The Nucleolus is found within the nucleus. It makes(or starts to make) the ribosomes used in making proteins. Microfilaments have…
