A cell is the basic unit of living organisms. From single cellular organisms to humans to trees, cells compose all of them. However, cells are split into two domains, those being Eukaryotes and Prokaryotes. Prokaryotes are all unicellular and are less advanced than eukaryotes; meaning that they lack a nucleus and only have a nucleoid region. They also lack membrane bound organelles. Prokaryotes are then broken into two kingdoms, Bacteria and Archaea. Bacteria are the less advanced of the two and…
How is the membrane structure related to the transport of materials across the membrane? The membrane structure plays an important role in the transportation of materials across the membrane. The Cell membrane is a barrier that separates a cell from its surrounding environment. This is composed of Phospholipids, Proteins, Cholesterol and Carbohydrates. The Membrane Structure has a very important role in the transportation of materials across the membrane. The membrane of the cell is made up of…
For example, in class we did not go in depth as much as the readings did, but there were still a lot of similarities between the two. In class we talked about how the mitochondria and chloroplast once were separate, but to evolve they joined with a larger host cell to protect them and they in turn provided the extra energy needed to make the host cell function. However, the text went into more detail describing how and why it happened and…
I. The most basic unit of life is the cell. All living things are composed of cells. Cells may only from through a process of division and replication of previously existing cells. Cells are microscopic; however their structure is complex. All types of cells possess a plasma membrane which separates its contents from its surroundings. . There are two types of cells: prokaryotic and eukaryotic. a. Prokaryotic cells are simpler than eukaryotic cells. Within prokaryotic cells are bacteria cells…
Why will it make me cringe if you ever say that cells “make” energy? Energy cannot be created or destroyed. It can only be transformed. An example would be chloroplast converting sunlight with is light energy into chemical energy to allow work for cellular functions. 7. How is the structure of a lysosome related to its function? Lysosomes are membranous sacs that contain digestive enzymes also known as hydrolytic…
Based on evidence, if a Protist could “protest” and be reclassified into another kingdom, which Protist could you help make the most convincing argument? To begin with, “Protista kingdom is sometimes called the, “junk drawer kingdom,” for the classification of living things. (Art. 1) When an organism’s characteristics do not quite fit into the fungus, plant, or animal kingdoms, they get classified into the Protist kingdom.(Article 1)”When scientists can’t figure out where to put organisms…
Chlorophyll is a component derived from cyanobacteria and from the chloroplasts found in plants and algae. It is an important component for photosynthesis. In the culinary world, chlorophyll is primarily used as a food additive for additional color or for other benefits. Chlorophyll is not water soluble. What Does Chlorophyll Do? There are many claims to the health benefits that chlorophyll present. Humans do not have chloroplast, which is where chlorophyll is derived from. Chlorophyll has to…
“No!” the king's wife cried. “My husband has fallen upon the ground, dead! Oh, how could this ever happen to me! What have I done wrong!” How would you feel if I told you that this dramatic play had something to do with a plant cell? Well, first off, it’s not just dramatic plays, any play will do. Secondly, there are a lot of organelles in a plant cell so I will just be stating the organelles that I think best correspond with different parts needed to produce a play. This piece of writing will…
located in the anterior end. They also contain a red eyespot at the anterior end that is able to detect light. Since Euglena lack a cell wall, they contain a pellicle composed of a protein layer. They usually live in quiet puddles or ponds. They have chloroplast that traps sunlight which is used for the process known as photosynthesis. Since Euglena can absorb food from their environment, they are not considered autotrophic completely. When light is not available, they become heterotrophic and…
occurs in the membrane bound chloroplasts, which are abundant inside the cell. Although both cellular respiration and photosynthesis share some similarities, it is important to note that photosynthesis, unlike cellular respiration, is an anabolic process.(Harris-Haller) This strenuous process works efficiently…
