Biology : The Base Of Biology

There are many parts of a cell, they all have specific duties, and are all

My analogy from a cell is to a city. A cell has a cell membrane and in a city the city border acts as the cell membrane. The city wall in a cell acts like a cell wall. The cytoplasm can be a lawn in a city. Highways or road systems act like the endoplasmic reticulum in a city. The ribosomes in a cell organelle can be considered lumber or brick yard in a city. In a city post offices and UPS act as the golgi bodies. Solar energy plants are considered chloroplast. A city hall fence with a security guard can be considered as the nuclear membrane. Energy plants in cities can be considered the mitochondria. In cell organelles there is the nucleus and in a city the nucleus would

According to Mattias Schleiden and Theodor Schwann the cell is the basic unit of life(Cell Theory- OI). Two common types of cells are the plant and animal cells. Although both kinds of cells share many similar, abundant structures, they also have varying descrepancies from cell to cell. Without a doubt, the nucleus is the most important organelle in the plant cell, even though, the lysosome is the most important structure in the animal cell.

Lakoff and Johnson state, “[w]e have found, on the contrary, that metaphor is pervasive in everyday life, not just in language but in thought and action” (3). They are saying that metaphors are used all the time and not just when people talk, but when they think and in what they do. This is exactly true because after learning about metaphors, and getting a better understanding of them, I have realized how much I, and others, apply them to everyday life without even realizing it, or trying to. Using a metaphor to describe Haas and Flower’s reading concepts will therefore make for a better grasp of what the concepts mean.

Cells are the basic units of structure and function in an organism, and Cells come only from the reproduction of existing cells.

Generally, people see metaphors as a device of the poetic or literary imagination: a figure of speech or a rhetorical flourish. However, metaphors are so much more. First, they form a kind of conceptual system, influencing both cognition and emotion. They frame how people think about difficult or complex problems. “The importance of metaphors to language in general, and rhetoric in particular, cannot be overstated. Metaphors are the foundational element of language through which our concepts and meanings are formed” (Cox). Second, they provide insight into the rhetor’s thoughts, opinions, and attitudes. The metaphors one chooses to employ act like an ideological footprint, identifying how the person truly feels or thinks.

Interviews began as students were shown a model of a cell which is shown in Image 1. Students were first asked the stem question, “What is this a model of?” From there students were asked, “Where do cells come from?” The probing questions asked to students were dependent on their responses, but were asked in order to reveal their knowledge of cell division. Three student responses are described in this paper, as they revealed a variety of prior content knowledge. Three

P1 – Describe the microstructure of a typical animal cell and the functions of the main cell components. A typical animal cell is seen as a tiny, three dimensional sac which is in fact made up of many components, each as important as the other. The microstructure of an animal cell was in fact uncovered mainly through the use of both cell fractionation and electron microscopy. Each main component has its own, individual function which helps a cell to function and maintains the cell membrane. The components that I will be describing include the cell membrane, nucleus, cytoplasm, mitochondria, lysosomes, Golgi bodies, centrioles, endoplasmic reticulum (both smooth and rough) and ribosomes.

Cell Biology, BIOL 293, is one of ODU’s ‘required biology core courses.’ The course will focus on the structure and function of the cell; it will also focus emphatically on the notion that the cell is the basic unit of life.

Cells can be traced back to the basic structure of life. Cells make up all organisms such as, plants, the human body and fungi. There are different types of cells. The thing that differentiates Eukaryotic cells, which are animal and plant cells from Prokaryotic cells is the membranous organelles that are in the cytoplasm and chromosome proteins. The Eukaryotic cell nucleus contains most of the genetic material and controls all activity. mRNA translation happens in the ribosomes which carries out protein synthesis of the cell, while DNA replication occurs at the nucleus. Ribosomes are critical for protein assembly which is important for cellular functions. Also, there is endoplasmic reticulum, it has 2 type: rough and smooth. Smooth endoplasmic reticulum is responsible for metabolic processes and lipid synthesis.

Properties of life enable biologists to distinguish living from non-living things. These properties include response to stimuli, reproduction, order, processing energy, Homeostasis, adaptation, growth and development (Wayne, 2009). Living things have the ability to adapt to the surrounding environment in order to continue surviving in the changing environment. They also require energy for metabolic activities, which is either produced from the sun or acquired from food. It is critical that living things also maintain their internal body conditions such as temperature, and PH through a process called homeostasis. Regulation or excretion is where living organisms have the capacity to get rid of unwanted materials from their bodies. They also grow and develop because they increase in size and the complexity of their cell structures improves. Ultimately, living things respond to stimuli reproduce, and have an order in their body structures.

The cytoplasm is the area between the nucleus and the cell membrane. The cytoplasm contains many important structures. This area is basically the main place where you will find structures that help the cells stay alive.

In order for cells and organisms to “live” they need to perform certain tasks such as produce energy through respiration, send messages, maintenance and reproduction. To enable the cell to do so, it contains within small structures called organelles, each organelle is different and carries out a specific function.
