Oogenesis
The formation of the ovum (mature female gamete) from undifferentiated germ cells is called oogenesis. This process takes place in the ovaries (female gonads). Oogenesis consists of three stages known as the multiplication phase, growth phase, and maturation phase.
Cell Division
Cell division involves the formation of new daughter cells from the parent cells. It is a part of the cell cycle that takes place in both prokaryotic and eukaryotic organisms. Cell division is required for three main reasons:
Step by step
Solved in 2 steps
- The image below is an Allium root tip under the microscope. Which statement describes what we are seeing? -dozens of cells in different parts of the cell cycle, mostly interphase -dozens of cells in different parts of the cell cycle, mostly telophase -dozens of cells in meiosis -one cell with many many nuclei dividingLabel the Paramecium plain and Identify whether it is eukaryote or prokaryote and Indicate the type of cellular reproduction process the cell undergo: Make drawings of the three different cells types (Elodea leaf, / carrot / potato) and include on each drawing the following information: Names of the following structures: cell wall, plastid. Name of the specific plastid in each of these specimens (chloroplast/chromoplast/amyloplast). The total magnification used for these images
- Label the cell diagramLabel A-H from image as the following: I: Dikaryotic II: Basidiospores III: Plasmogamy IV: Meiosis V: Diploid VI: Haploid VII: Karyogamy VIII: ZygoteLabel the Amoeba and Identify whether it is eukaryote or prokaryote and Indicate the type of cellular reproduction process the cell undergo
- What are the stages of mitosis. Nuclear membrane is disappearing. Spindle fibers form and become visible cell plate (plant) or cleavage furrow (animal) forms and is visibleLabel each part of plant and animal cellcreate a Venn diagram of the following types of cell division processes: mitosis, meiosis, and binary fission.
- Which of the following cell components is not visible using a compound light microscope? a. Nuclei b. Chloroplasts c. Mitochondria d. Vacuolesdraw the cells in the given imageSome slime molds violate the first element of cell theory because? they have no nuclei in their cells. they do not arise from pre-existing slime molds. their cells have still smaller cells living within their cytoplasms. the entire slime mold appears to lack separate cells in its structure. they do not reproduce sexually.
