plants, and are considered a process of evolution as they have evolved in order to adapt to the change in the environment. In this investigation we will be observing the results of both types of plants under harsh conditions. It is preferable that the Polyploidy plant will survive harsher conditions as they have actually developed due to the change in their biosphere therefore making it more likely that they will survive unfavourable conditions. In this experiment we will be taking a look at which

Cell Respiration Lab Research Question What is the optimal temperature for germinating pea-seeds where the rate of respiration is the greatest? Background Information Cell Respiration refers to the biochemical process conducted by the cells of an organism that combines glucose and oxygen to produce energy in the form of ATP, along with two by-products, water and carbon dioxide. The equation representing this chemical reaction is shown below. C6H12O6 + 6 O2 6 CO2 + 6 H2O + ATP Although plants and

the mitochondrion or the primary plastid. Most proteins targeted to mitochondria and primary plastids carry N-terminal transit peptides that are later removed in the organelle matrix. Mitochondria and primary plastids are surrounded by two membranes. Consequently, their import machineries are composed of two translocons: one for the outer membrane and the other for the inner

It states that the origin of eukaryotic cells is from prokaryotes. Mitochondria and plastids have similarities with bacteria, thus they differ from other organelles inside eukaryotic cells. The discovery of mitochondria being an exceptional cell organelle led Dr. Lynn Margulis to develop a theory of mitochondrial evolution. The theory of mitochondrial evolution, endosymbiosis, states that mitochondria and plastids have an extracellular origin. This essay focuses on endosymbiosis and its path from

such as the Saccoloma species. Polypodium glycyrrhizas Domain is Eukarya, its put into this category because they contain nuclear envelope and membrane-enclosed organelles in its individual cell. Its Kingdom is Plantae because of its definitive plastid developed from primary endosymbiosis. Its Phylum is Pteridophyta, Pteridophyta means "feathered plant". It fits into this category because it is defined as a fern. Its

A genetically modified organism, or GMO, is an organism that has had its DNA altered or modified in some way through genetic engineering. Genetic engineering is a common and essential practice in biotechnology, to harvest organisms with traits which are more favorable for the human population. The development and marketing of GMOs to provide cheaper, yet more durable and nutritional products has made a huge impact on the environment and on agricultural practices around the world. According to National

bacteria and viruses become resistant to antibiotics and soon bacteria and viruses will resist all antibiotics. (“Frequently Asked Questions…” np). This is why, scientists study the evolution of bacteria’s immune system. Viruses mutate to develop plastids that resist antibiotics, this forces scientist to create new antibiotics. People are also guilty of using more than the needed amount of pesticides. “Similarly, the use of pesticides in agriculture has driven the evolution of resistant insects, requiring

With only two classifications of all organisms, Eukaryotes and Prokaryotes, the question about similarities and differences by these two types of cells is often raised. A lot of the curiosity revolves around how they may be related, share evolutionary links or what makes them diverse. While Prokaryotic cells and Eukaryotic cells share a few similar cellular structures and basic molecular mechanisms that could indicate links, the amount of differences that exist between these two types of cells can

sunlight to synthesise nutrients from water and carbon dioxide. (source 1) Photosynthesis includes a significant scientific background behind it. The process takes place in chloroplasts, which is a type of plant cell organelle frequently referred to a plastid. They are recognised to be eukaryotic cell structures. The chloroplast a green pigment known as the chlorophyll. The function of the chlorophyll is to absorb light for photosynthesis. Here is what a chloroplast looks from the inside just as well

Biology Semester 1 Research Project Cellular Process Meagan Baggett 4th Period The endosymbiotic theory explains how eukaryotic cells may have evolved from prokaryotic cells. Symbiosis is a close relationship between two different organisms. The discovery of the endosymbiotic theory took hundreds of years to be considered as real and was eventually it was finalized. The endosymbiotic theory is believed to be first introduced and described by Andreas Schimper in 1883. Schimper was a

A cell is a basic unit of life, without cells there would be no life on earth. Cell are building block of all living things without cells there would be no life on earth. The first living cell was discovered by a Dutch microscopist Antonie Van Leenuwenhoek(1632-1723). The are two types of cells namely prokaryotes and eukaryotes. Both eukaryotes and prokaryotes were first introduced by a Frenchman Edouard Chatton in 1938. Prokaryote is a unicellular organism that lacks the nucleus and other membranous

believe there are long-term changes in your metabolism. Plant Cells Prompt Your response Describe the primary structures in plant cells. The primary structures in plant cells are the nucleus, Nuclear Membrane, Cytoplasm, Cell Membrane, Cell Wall, Plastids,

Mitochondria are found in a large majority of eukaryotic cells, with their main function being to produce ATP from gathering energy from the oxidation of food and to take up oxygen, giving energy to the cell for it to carry out its functions and activities.(Friedman J.R. and Nunnari, J (2014) ‘Mitochondrial form and function’. Nature (505), pp 335-343). Mitochondria have been essential for the development and evolution of animals, without them far less effective methods of making energy, such as

Photosynthesis is an important factor in life on Earth. Earth requires a constant input of energy from the Sun. As the molecules from the Sun are converted, energy in the form of photons are produced, passing to Earth. The ones with wavelengths within the visible light portion on the Electromagnetic spectrum are absorbed by pigments in the chloroplast of plants starting Photosynthesis. (2) Photosynthesis is the complex process by which carbon dioxide, water and certain inorganic salts are converted

2003). The formation of these crystals is specific where they have a defined shape and specific site. It usually takes place inside the vacuole of specialized cells called crystal idioblasts. The specialized cell has enlarged nucleus, specialized plastids, increased endoplasmic reticulum, elevated levels of rRNA, and unique vacuolar components. The abundant Golgi complexes in these idioblasts have also been found to be involved in transporting a calcium binding crystal idioblast specific protein,
