from. Simply having done this research opens new doors to many possibilities. According to previous studies, mesophyll cells are specialized for photosynthesis (Richardson 302). These cells in the middle of the leaf contain many chloroplasts, the organelles that perform photosynthesis. In the plant cell structure gas exchange, oxygen and carbon dioxide takes place within the chloroplasts, and the food produced by the chloroplasts must move out of the cells to other parts of the plant (Richardson…

found almost everywhere; in soil, water, food, plants, animals as they can survive in a range of extreme conditions. Bacteria are tiny, single-celled, prokaryotic microorganisms belonging to Kingdom Monera. Bacteria cells lack a nucleus and other organelles bound by a membrane and are structured by many different features. Bacteria have a flagella, cell wall, cell…

To understand how homeostatic mechanism regulates the human body’s temperature, we must know and understand the organization of the human body and how it relates to homeostasis mechanism adapting to the external changes, such as the weather. It will be explained how the stimulus, receptors, integrator, effector, and the different tissue types play a key role in how the human body responds to changes in temperature. The human body is complex and consists of several levels of organization (Ireland…

The typical organelle that prokaryotic cells use for movement is the flagella. The flagella is a tail of sorts that connects and projects out of the cell wall and propels the cell forward (6). On the outside surface of a bacterial cell, it is likely to find appendages…

photosynthetic process involves two separate stages: the light cycle in which the plant converts light energy into chemical energy and secondly, the Calvin cycle which uses that chemical energy to make sugars for food. To perform these processes, plants use organelles called chloroplasts that absorbs light to fuel the plant. These chloroplasts are consisted of different pigments that absorb specific wavelengths of light, with the two most abundant being chlorophyll a and chlorophyll b. This lab…

Electron microscope (Manning, n.d.) is the instrument used to magnify different scientific artifacts with the used of electron beams to create the illustration of the sample, and has the capacity to magnify two million times of the original specimen. The development of the electron microscope was first known in the year 1931 because Ernst Ruska and Maximoll Knoll magnified electron image successfully, but the equipment was actually constructed in 1933 (Innes, n.d.). The concept of the electron…

of dendrites. Although neurons are a diverse set of cells, most neurons share certain features in their structural form - the cell body, the axons and the dendrites (2). The cell body contains the nucleus of the neuron and other intracellular organelles. This spherical-shaped…

1. Introduction Alzheimer’s disease can be characterized as a neurodegenerative disease where an individual suffers from progressive loss of memory and basic mental functions. Because researchers cannot pinpoint a specific factor that causes Alzheimer’s disease, many theories exist regarding its causation. One such theory, the dysfunction mitochondria within an individual’s brain cells, the organelle’s DNA mutation, and the implications these two variables have on the causation of Alzheimer’s…

Prokaryote that have been around longer than Archaea and Eukarya. Bacteria appeared on Earth 4 billion years ago and are said to be the first forms of life (Nordqvist). The cell of bacterium does not have a nucleus and is without membrane-bound organelle. Bacteria can be rod, sphered or spiral shaped. Bacteria are the most plentiful organism on Earth; as well as being the most various. Humans and plants could not survive without bacteria. Reproduction in the form of binary fission is how…

carbohydrates and amides into new structures including enzymes and permanent storage such as starch in seeds. Growth includes monomer synthesis, polymerization of monomers into polymers such as cellulose and proteins, organization of polymers into organelles and cells and tool maintenance…
