HELP! Need a catchy title for a cell project...?
Plantastic Animal Cells! haha its cheesy Animal and Plant cells: discovery A look at Plant and Animal Cells You say Eukaryotic, I say Prokaryotic (eukaryotic, prokaryotic!) Animal and Plant cells: The same, or are they really different? Let's Learn about Plant and Animal Cells! Animalistic Plant Cells Plant vs. Animal Cells: The Truth (truth, war, battle, comparisons)
Many cells do not have mitochondria. The mitochondrion, an organelle that helps produce energy for the cell, is only found in eukaryotes, organisms with relatively large, complex cells. These organisms contrast with prokaryotes, which lack membrane-bound organelles like mitochondria.Prokaryotes may have been the precursors of mitochondria. The Fossil Musuem notes that, according to Dr. Lynn Margulis' endosymbiotic theory, a certain bacterion may have engulfed another bacterion and incorporated it as a symbiotic organism. In time, the engulfed bacterion became wholly dependent on the host cell to survive. The arrangement was beneficial to both species, so the internalized bacteria was replicated and passed down to later generations. This became the origin of the eukaryotic cell and organelles.
Hi :).. i need to create a project comparing cell structures to real life things and make a "cell city"?
This question is total nonsense. They allow transgendered women, as in women who were born with a male anatomy from birth. They do not allow transgendered males (men who were born with a female anatomy from birth). You have the terms mixed up. Race for life does also allow boys under the age of 12 to run and they DO allow male support, they don't however typically allow males to run in races due to it being an organisation geared towards supporting women with breast cancer. It states this on their website: "Race for Life are happy to accept entries from transgender women. However, as Race for Life is a female only event we have a promise and responsibility to our female supporters to ensure our Race for Life events are represented by women only. This means that anyone who is not a woman or transgender woman is not eligible to participate in Race for Life. There are, however, a variety of other events Cancer Research UK supports that everyone is able to take part in." Males over the age of 12 are excluded because it's a female event, due to it being a charity for breast cancer. Very few males suffer with breast cancer, for women it's a very serious and life threatening matter. It isn't sexist, they are just supporting their female racers and trying to unite women in fighting breast cancer.
What can i use for an edible eukaryotic cell?

Mitochondria: Some are "roundish", some are long ovals. Some kind of "peanut-shaped" candy, or something that you can carve into that shape would work. Your teacher is only doing this because he/she wants students to bring all kinds of deserts to class. Excuse for a desert party! HaHa.
Creative Biology Video Presentation?
My biology lab partner and I have to give a presentation for our last week of class...does anyone have any unique ideas or has done something creative with a topic in biology? We want to do a creative video of some sort. The topics we've discussed in class are cells, prokaryotes, eukaryotes, photosynthesis, cell respiration, evolution, genetics, etc. Things mostly on the microscopic and biochem level. I was thinking we could do a video and pretend to be professors in a class informing students on a particular topic, (call it like, "The shortest lecture you'll ever experience") or do like a short "information" session like for a news station (call it like, "Your daily dose of science"). Is that cheesy? I thought about talking on meningitis since that's a bacterial infection and affects adolescents and college students most frequently, but the research information is a little more detailed than what we have knowledge about...My professor is really lax on this, she said for all she cares we can dress up as viruses. So, if you've ever done something creative or have some great ideas please help! Thanks!
Any creative ideas for making a cell model? (not edible)?
I know this would be hard, but if you are looking for a truly original idea... try Legos. I would be expensive and time consuming, as well as very difficult. If you could manage to put it together I would think everyone would be interested and entertained by your project. Basically, my idea would involve a lot of single colored Lego blocks (mainly green and any colors which you choose to represent the various organelles of the plant cell), and a flat surface to use as the base (which Lego does make). Depending on the size and how creative you choose to get it could get kinda pricey, but having done a Lego art museum for a project last semester I know it can be done given time and money. I would go for something around the 2in x 12in x 12in department, that way it gives it some depth and enough space to easily identify the various cell parts. You could use Lego flag poles or toothpicks with little neatly hand-written notes to denote the cell parts. That's my idea anyway. It would be cool if you could pull it off and definitely original. I would love to see it if you could make it happen. Edit: Luckily I checked in on this question, I was worried about ya. So, it's due Friday huh? How about Play-Doh or better yet colored clay? It's cheap, it's easy, it's fast, and it's fun. Here's what you do... Go to any arts and crafts store, like a Michael's or something. Find a number of blocks of colored clay - use green for the large base structure of the cell. Make sure to identify the individual parts of the cell with different colors of clay and it might be smart to make a neat ring of light green clay to represent the cell membrane. I would say make it about 1 foot in diameter, and you can choose to bake it if you wish, but I would look up on how to do that if I were you before you do it and possibly ruin your work. It would look much better if you did though. Again, you can use toothpicks and neatly drawn signs to indicate the cell parts. Good luck to you, and if you can let me know how it works out.
I’ve never seen (or read about) cilia within a cell — Wikipedia (article: Cilium) offers a good answer:A cilium (Latin for eyelash; the plural is cilia) is an organelle found in eukaryotic cells. Cilia are thick protuberances that project from the much larger cell body. There are two types of cilia: motile cilia and nonmotile, or primary cilia, which typically serve as sensory organelles. In eukaryotes, motile cilia and flagella together make up a group of organelles known as undulipodia. Eukaryotic cilia are structurally identical to eukaryotic flagella, although distinctions are sometimes made according to function and/or length. Biologists have various ideas about how the various flagella may have evolved.Cilia examples image lifted from dev.biologists.org.
Vacuole in a plant cell and an animal cell?
Vacuoles are membrane-bounded compartments within some eukaryotic cells that can serve a variety of secretory, excretory, and storage functions. Vacuoles and their contents are considered to be distinct from the cytoplasm, and are classified as ergastic according to some authors (Esau, 1965). Vacuoles are especially conspicuous in most plant cells. In general, vacuole functions include: removing unwanted structural debris surrounding the cell sequestering materials that might be toxic to the cell containment of waste products maintaining internal hydrostatic pressure or turgor within the cell maintaining an acidic internal pH storing small molecules exporting unwanted substances from the cell. enabling the cell to elongate rapidly or otherwise alter relative cell size. Vacuoles also play a major role in autophagy, maintaining a balance between biogenesis (production) and degradation (or turnover), of many substances and cell structures. They also aid in destruction of invading bacteria or of misfolded proteins that have begun to aggregate within the cell. Autophagy is especially prominent in insects that undergo complete metamorphosis; for example, larval tissue is recycled to become appendages in an adult insect. More at Wikipedia...
It is very unlikely that we would be able to transfer the entire human genome into a bacterial cell. The reason is simple. It is just to huge.The typical length of a bacterial genome is 15 mega base pairs, while the human genome is 3 giga base pairs (and that’s just one half, because we are diploid and carry two copies of our genome in every cell).An average bacterial cell (E. coli) has a volume of 1µm³. This is a third of the size of the human cell nucleus, where our genome is stored. The human cell nucleus has a volume of around 3µm³.Also, how do we get the DNA in there? We cannot just inject it, there are no needles that thin. In molecular biology we still rely on the bacteria basically taking up the DNA from the environment basically by itself. We can just help a bit by heat shock or electroporation. There is no way, that the entire human genome would just enter “by itself”. And here I’m not even considering, that the genome is present in 23 (x2) parts. The chances of getting them all in individually are even slimmer.Apart from that, it is really not useful at all to put the entire thing in there. Human and all eukaryotic DNA has many features with which a bacterial cell has no idea what to do. Eukaryotic cells have several mechanisms to process the DNA before it gets used. Bacteria lack these mechanisms.So I’m sorry to disappoint, but whatever you have in mind does not work like that. I hope I could answer your question. And if you’re interested, why not tell me, what brought you to that idea? Maybe there is a simpler solution than transferring the entire human genome into a bacteria :)Best regards.Nils
