Prokaryotic cells are different than eukaryotic cells in many ways. Prokaryotic cell means before the nucleus and eukaryotic cell means possessing a true nucleus, emphasizing that a prokaryotic cell doesn’t have a nucleus and a eukaryotic cell do. Other differences are the types of organelles. Prokaryotic cells have free floating D.N.A. and eukaryotic cells have it enclosed in the nucleus. Also prokaryotic cells have the ribosomes by themselves while eukaryotic cells usually are ether free or attached to the rough endoplasmic reticulum. Some prokaryotic cells include flagellum and eukaryotic cells don’t. 2) Why are these cells eukaryotic? What advantages and disadvantages does this give? Answer: plant and animal cells are both eukaryotic because they both have a nucleus. The …show more content…
By having a nucleus, there are more components that are specialized to do specific jobs because they have a ‘’boss’’ to tell them what do. The disadvantages of being a eukaryotic cell is that by having the nucleus the D.N.A. cannot get out so they have to send the mRNA to the job for them and travel out of the nucleus which takes a little more time. It is also harder for the cell to reproduce because of all the organelles it has to copy and split and to finally reproduce. 3) How are animal and plant cells different? Answer: Plant cells and animals might both be eukaryotic cells but they have their differences. Plant cells can make their own food by a process called photosynthesis. Photosynthesis occur in the chloroplast which absorbs the energy from the sun and transforms it into food. Plant cells have a cell wall which gives them structure, support, and shape to the cell.

1. Nucleus- present only in eukaryotic cells, this structure stores most of the genetic information of the cell. The nucleus directs the production of proteins through the synthesis of mRNA. 2.
Organelles as organism is from The Lives of a cell authored by Lewis Thomas. Thomas uses a unique writing style that is very recognizable and different from the others. This helps us to appreciate our diversity as human beings demonstrated by our abilities to write differently. As a reader one is able to form an image of who Thomas is by how he expresses his feelings and attitudes. When this text was written a lot of people, mostly scientists, thought and had knowledge of different things than they do now.
The interesting question scientists raised is, can we relate to them? The answer is ‘yes’. For instance, the genes necessary to tell a plant whether it is light or dark, time cell division, and promote the proper functioning of the immune system are contained within the human genome as well. (Armstrong) “People have to realize that plants are complex organisms that live rich, sensual lives.” (Scientific American) Plants smell, taste, feel pain, have memory, and communicate.
Unlike archaea and bacteria eukarya is the type of cell with a nucleus.
Cellular world can be divided into two types, depending on the presence of nuclei inside cells. Eukaryotic cells have a well-defined nucleus surrounded by a nuclear envelope, whereas prokaryotic cells lack this compartment. All bacteria are prokaryotes. Bearze (2015) provided information about the Bacterial Cell Structure and Function. Vibrio cholerae is a gram negative, non-spore forming, curved rod that is oxidase positive.
Even though we cannot see cells without a microscope, they are the basic unit of life and they exhibit all of the characteristics of living organisms. They can exist individually, as do bacteria, or they may work together, taking on specialized tasks to create a more complex organism. However, all living organisms share certain characteristics, which are discussed below. Cells are made of cytoplasm.
All organisms use food molecules, like glucose to produce ATP. The production of ATP occurs during cellular respiration. ATP provides the cells with energy that is necessary to produce oxygen. The seeds/plants are autotrophic organisms, which produce their food from the energy that the light provides them. To release the stored energy within the food molecules, the germinated seeds carry out respiration and the release of carbon dioxide.
A plant cell also has organelles. Finally, a hallway compares to a plant cell by the reason of that they both are in the shape of a
Did you know that there are over 82 schools in virginia beach? In many ways, an animal cell can be compared to a school. The Organelles’ roles in the cell align with the functions of a school in many different ways. Some examples are the Cytoplasm, Cell Membrane, and the Nucleus. One object in a cell that can be compared to a school is the Cell Membrane.
Both plant and animal cells are eukaryotic cells and they both have organelles which performs a specific function. What makes plant cells different from animal cell is that plant cells have a cell wall which provides it with support and protection. Plant cells also have chloroplast, which provides food for plant
Plants take carbon dioxide and water and turn it into sugar and other compounds. Sugar is produced and used by plants for its life process, like growing and reproducing. Oxygen is produced to replenish the oxygen that was used up by living things during respiration. Autotrophs make food for their own use but they make enough to support other lives as well. Photosynthesis gives the most energy for life on earth.
One of these things that makes up a eukaryotic cell is a nucleus. A nucleus is an
This diagram identifies the eukaryotic cell is more evolved than the prokaryotic cells and has a more complicated structure. Eukaryotic cells are what makeup animals and plants. Unlike the prokaryotic cells most eukaryotic cells contain a nucleus surrounded by nucleoplasm within its own membrane and the eukaryotic cell contains many more types of organelles than the prokaryotic cell. The nucleus contains the DNA of the cell and coordinates the cells functions that include growth, reproduction, metabolism and protein synthesis. On the edge of the nucleus are nuclear pores, this allows the nucleus to communicate with the rest of the cell, found within the nucleus is the nucleolus a dense structure of a crystalline protein and nucleic acid used
Thus they are both intracellular and extracellular. 1. Lysosome cell organelle has
Bacteria usually have capsules, but archaea rarely have one. Inside the prokaryote is cytoplasm and a nucleoid. The nucleus is not enclosed inside of a membrane in prokaryotes. The cell may have appendages to adhere to certain surfaces or for motility. The prokaryotic cell is smaller than the eukaryotic cell and has different qualities that make the cell less complex than a eukaryotic cell.
