Transcript of Eukaryotic Cells
Designed to teach 7th grade life science, biology. . .
This virtual field trip is designed to, in accordance with the 7th grade science standards, take students through the functions and systems of a eukaryotic (animal) cell.
Mitochondria & Chloroplasts
These organelles are responsible for the production of energy to run throughout the cell. They are also organelles that orginated and evolved from the single-celled prokaryotes.
The Endoplasmic Reticulum . . .
Small organelles called ribosomes, floating in the cytoplasm or from the nuclear envelope, supply proteins through the form of amino acids.
Eukaryotic Cell: A Virtual Field Trip
The Cell Membrane
This is a squishy type of "city gate" or "border police", which monitors what comes in and out of the eukaryotic cell. What lies beyond these gates is the collective cytoplasm, a solution of water, nutrients, and protein strands. This in turn encompasses the cell-city's "infrastructure."
The Eukaryotic Nucleus
This organelle is surrounded by its own nucleoplasm. Its job is to order the other organelles around. It is also home to the cell's DNA and chromosomes.
Components (organelles) of the Eukaryotic Cell
Let's take a look at a video--"Eukaryopolis," An Analogy of the Eukaryotic Cell to a City: the "Fascist Swampland"
What is Eukarya? How does a Eukaryotic cell function?
A eukaryote is basically any multicellular organism (animal , plant, fungi cell) that contains a nucleus and other organelles enclosed within membranes. The distinctive feature of eukaryotic cells (in comparison to prokaryotes) is the genetic material contained within the nucleus.
Animals cells . . . How do they function?
Or the ER, is a network of membranes that distribute particular properties and molecules throughout the cell. The rough ER has ribosomes attached to its surface, while the smooth ER does not. The ER, as a collective whole, is kind of like the city's "factory-warehouse". Generally, the ER supples ions (energy), proteins, enzymes, and lipids
The way cells work in general in our body! A short clip from the film "Osmosis Jones"
Some useful websites to find out more about Eukaryotic Cells . . .
1. For comparing Eukaryotic Cells to Prokaryotic Cells:
2. For an in-depth anaylsis into the organelles of the Eukaryotic Cell:
1. After having looked at both Eukaryotic and Prokaryotic cells, which organelles are present in one that aren't in the other?
2. Describe one Eukaryotic organelle--its function, as described in both videos and the websites you've studied in this lesson. What organelle in the Prokaryotic cell is most similar to this one?
3. According to the Eukaryopolis video, which organelle is encompassed by its own type of "plasm" within the Eukrayotic cell?
Right click and '"open hyperlink" the link below. We will be taking a look at a website called "Cell Models: An Interactive Animation."
Click on the box with the red type underneath indicating that it's the interactive animal & plant cell animation.
For the focus of this lesson, we will be looking at the animal cell animation right now. Click on each feature of this type of cell to learn more about these organelles.
Let's visit a website on cells.
Can you identify each organelle's function?
The Golgi Apparatus
Ribosomes, in turn, are distributed by the ER to the Golgi Apparatus. This particular organelle is like the cell-city's "post-office", transforming and distributing proteins into various types of molecules.
Now go back to the animation website we looked at in the beginning of the lesson. Study the prokaryotic cell for a bit
What are the primary differences between animal (eukaryotic) and plant (prokaryotic) cells?
*English Language Arts 7 grade: Compare and contrast a text to an audio, video, or multimedia version of the text, analyzing each medium's portrayal of the subject.
*Science Content Standards Grade 7--Cell Biology 1b:Students know
the characteristics that distinguish plant cells from animal cells,
including chloroplasts and cell walls.
