ADI Lab How should the unknown organisms be classified? Using previous knowledge from tenth grade biology, we know the variation between plant and animal cells. The differences are within the organelles. Animal cells have centrioles, lysosomes.
Unlike archaea and bacteria eukarya is the type of cell with a nucleus.
- This organism is Eukaryotic based on the sole fact it has a nucleus and it most likely belongs to the Kingdom Protista. I would say there is reasonable evidence that it could either belong to one of these groups: Radiolaria or Foraminifera. - This organism is a prokaryote because it does not contain a nucleus. It belongs to Kingdom Bacteria and most likely falls under Prochlorococucus. (Based partially on the fact that it is the most abundant.)
Prokaryote cells and Eukaryote cells are very different from each other with few similarities. Both cells are found within the five kingdoms, produce proteins, and can only be seen under a microscope. Eukaryote cells are complex and make up the plants, animal, fungus, and protists kingdoms, while the prokaryote cell is a simple bacterial cell. Although both cells have a nucleus containing DNA, the eukaryote cells have a double wall membrane around the nucleus, therefore, protecting the DNA inside the nucleus. Unlike the eukaryotes, prokaryotes have no cell membrane around the nucleus, making the DNA naked and more unprotected.
Protists are a collection of eukaryotes that lack distinct tissues. Protozoans are unicellular and heterotrophic. Algae is
The nucleus is the center of the cell, therefore, it directs all cell activities, contains genetic material (DNA), and the nucleus is also separated from the cytoplasm by the nuclear membrane. The nucleus is similar to a computer keyboard. The keyboard is used to enter data, generate commands and enter shortcuts such as copying, pasting, and deleting items. The mitochondria is a rod shaped organelle.
The process of cell division takes has many phases, but the most important part of the cell division makes sure that the genetic information is copied and passed on within every cell. The chromosomes divide, and duplicate themselves during the process of cell division. In eukaryotic cells, the cells create
Domain: Eukarya This domain contains all organisms that have eukaryotic cells, including members of the kingdoms Protista, Fungi, Plantae, and Animalia. This means that they store DNA in the nucleus within each of their cells. Kingdom: Animalia All members of this kingdom are multicellular and heterotrophic, in other words, they are consumers. They do not have cell walls, and most of them are mobile for at least some part of their lives. Aside from these characteristics, kingdom Animalia is incredibly diverse.
For today's discussion, we're focusing on the similarities and differences in DNA replication between eukaryotes and prokaryotes.
The nucleus is the most important organelle for a eukaryotic cell as it controls the cells growth and reproduction. The nucleus is enclosed by a nuclear envelope which similarly to the cell membrane is also made up of phospholipids and controls the movement of particles. The nuclear envelope is used to separate the nucleus from the cytoplasm. Within the nucleus contains
An Accurate Definition of an Organelle According to the Cell Theory, all living organisms are made up of two or more cells; they are considered the simplest unit of life. Cells are divided into two groups: prokaryote and eukaryote. Prokaryotes are single-cell organisms that are lacked of a nucleus, such as bacteria. Whereas, an eukaryotic cell is a multicellular organism that have a nucleus, such as an animal cell.
Which then line up in the middle of the cell in pairs of two prophase is what this is called. Then in anaphase centrioles pull the chromosomes apart separating them from their pairs, two nuclei start to reform in telepahse, and finally there are two new identical cells. The final result is two newly formed cells this step is most known as known as cytokenesis. These are cells that are identical, they are specific task cells like lung or hear cells, and are diploids meaning they have all forty-six chromosomes. The major different between meiosis and mitosis is that in meiosis there is no second interphase like in mitosis so the DNA doesn't replicate causing the unique cells you get in
Eukaryotic cells are quite distinct containing nuclear and cytoplasmic compartments. The nucleus is a membrane-enclosed organelle that is surrounded by a nuclear envelope (NE). In the cells a lot of transportation occurs. One of the reasons is that nuclear proteins are synthesised in the cytoplasm, but are needed in the nucleus. Another reason is that to be able to synthesize the proteins that are required for the cell, the different RNA species located in the nucleus are needed in the cytoplasm (6).
For an example the eukaryotic cell consists of different organelles such as mitochondria, releasing energy in the form of ATP. The organelles may be similar having slight differences whether in a root cell of a plant, a liver cell or sex cells. Plant cells on the other hand grow differently from animal cells, also with some of the common components being used up differently. For example plant cells have some organelles that animal cells do not have, such as the vacuoles that inhabit most of the capacity of an expanded cell, the cell wall and chloroplast. The profound differences are not taught in ks3 but rather the main basic differences (Chad chemistry n.d.).
