Lab Observations: Observing that each organism comes in various sizes Lab Answers: A. Estimate the size of: 1. An E. Coli cell. 2. 1 micrometers 2 A mitochondria. 0. 6 micrometers 3. A Red Blood cell. 8 micrometers 4. A hepatitis virus. 26 Manometers 5. A water molecule. 9 meters B. Observe the various Cell types and learn to distinguish between Bacterial cells, Plant cells (1, 2), and Animal cells (1, 2, 3) 1.
Observe and describe three differences between prokaryotic and eukaryotic cells. Prokaryotic Cells is a single celled organism, they have no nucleus and they don’t have a cytokines. Eukaryotic cells have a nucleus, they have a cytokines and are more complex organisms. 2. Observe and describe three differences and three similarities between plant and animal cells. Differences between a plant cell and animal cell- Animal cell does not have a cell wall but a plant cell does. Animal cell has more of a round shape while the plant cell is more rectangular. Animal cell does not have chloroplast but the plant cell does have it.
Similarities between a plant cell and an animal cell- Both have Cell Membrane, Both have Mitochondria Both have Nucleus C. Form a hypothesis 1. Hypothesize about how you might be able to sort a mixed population of cells into prokaryote and eukaryote. Try to be practical, build on your understanding of the differences between the two cell classes. The best way to sort mixed populations of cells into prokaryote and eukaryote is to note the differences between the two and group them accordingly. For example, Prokaryote cells don’t have a nucleus like the eukaryote ones do.
So separate all the cells that have nucleus and group them accordingly. 2. Hypothesize about a means to separate out plant cells from a mixed population of eukaryotic cells. Finding the differences between the two cells is the most important factor. Eukaryotic cells can be separated by using a quinine where the eukaryotic cells or cells that have cell wall attach themselves to other groups of similar cells which in turn separates them from other cells. Conclusions: The purpose of this lab was to observe that each organism comes in various sizes even though some of them are complex and have a lot of parts to them.
This lab’s purpose was also to identify how to separate Eukaryotic cells from Prokaryotic cells so that we can identify why each one is different and why each one is similar. Virtual Lab 2: Cellular Processes Is to identify the different stages (phases) that cells go through. Observing the cell phases in eukaryotic cells and prokaryotic cells. A. Bacterial Growth. 1 . Estimate how long it takes for this population of bacteria to double. Hint- this population doubles multiple times during the duration of this recording. Bacterial Growth population doubles about every half hour. B.
Cellular reproduction 1 . Estimate the percentage of time that a constantly developing cell spends in enterprise. A cell spends most of its time in enterprise, about 85% of the time. 2. In a random selection of 100 such cells, estimate the number that would be undergoing mitosis at any given time. About 25 would be undergoing mitosis 3. In a couple of paragraphs describe the basic differences between mitosis, meiosis, and binary fission. Mitosis is a type of cell division that takes place in somatic cells which is designed to increase the number of cells in both animal and plant cells.
During mitosis, the production of two product cells or “daughter cells” is made. Mitosis also has four stages that complete all the stages of mitosis. Meiosis is a type of cell division that takes place in eukaryotic cells. Meiosis has two cell divisions that produce sex cells that have half the chromosomes as each aren’t cell. (A major difference then Mitosis which has four stages ) Meiosis two stages are the GIG stage, which the cell increases in mass to ready itself for cell division. The second phase is called the S phase which is when the DNA is synthesized.
Binary Fission is a form of asexual reproduction that takes place in all prokaryotic organisms. (Binary Fission also takes place in some eukaryotic cells such as fungi) Binary Fission is basically cloning, the cell clones itself. C. Cellular metabolism 1 . In a paragraph or two compare and contrast photosynthesis and cellular aspiration. Photosynthesis is process that plant cells use to absorb energy from the sun. (Turns energy into food for plants) The solar energy is converted into chemical energy and chemical energy is turned into glucose (sugar).
The reason for photosynthesis is for plants to have a way to absorb the energy they need to survive. Cellular respiration is different than photosynthesis but they both have a similar job. Cellular respiration and photosynthesis both change energy into a form that can be used for the cells. Cellular respiration does not energy from the sun like Hottentots does, instead with Cellular respiration the energy is harvested by consumed food. When animals eat something, they get the energy they need from that food through the cellular respiration process. 2.
Describe the ecological relationship between photosynthesis and cellular respiration. Cellular respiration is the process that plants and animals use to break down energy that they need. Photosynthesis is how plants convert the sun energy into the type of energy that they can use to survive. Cellular respiration occurs in the mitochondria in animal cells why photosynthesis occurs in the holocaust in plant cells. The purpose of this lab was to study the difference between different stages in cells. Also, the purpose of this lab was to find the similarities between the stages of cells and different types of cells.
Stages that we covered were Photosynthesis, cellular respiration, mitosis, meiosis, and binary fission. V ritual Lab 3: Genetics The purpose of this lap is to study genetics and to see how they work and appear in living organisms. Lab observations was to see the genetics in flies and to apply them to human genetics or other genetic outcomes using punned squares. A Phenotype and Genotype of Dragons. You do not have to be able to access the Dragon website to answer these questions. 1. Define genotype and phenotype. Genotype- The genetic makeup of an organism or a group of organisms.
Phenotype – The appearance of the organism. (The physical trait) 2. What is an allele? Allele is an alternate form of a gene. B. Drosophila Lab. Enter as a guest. Buy and then breed a mutant black bodied female with a wild type (i. E. Standard) male. 1 Describe and explain the characteristic of the first generation (Fl ) of flies. Is the black bodied characteristic dominant or recessive? When doing the lab the black bodied characteristic was recessive. The flies came out looking like the male, with the black like stripes instead of the full black body.
But the flies did have the mixture wings like the female fly. 2. Assume the black body female’s genotype to be b and the wild type male’s genotype to be WWW and fill in the following Punned square. Are your breeding results consistent with what you expect from this assumption and the logic of the Punned square? My breeding results are the same logic. The flies had dominate traits from both parents. Bow b bow 3. Breed two of these Fl flies. To do this select a male and a female from the results of your first cross and put them in the breeding jar.
Describe and explain the characteristics of the second generation (IF) flies. When breeding the second set of flies, the results came with 8 different types of flies. Some of the flies had black bodies with small wings, some of the flies were black bodied without the small wings and some of the other flies were the same color as the father with the stripe color body. 4. Use a Punned square to predict the ratios of a cross between two WBI individuals. Is this consistent with your experimental observations? This is insistent with my experimental observation. C.
