When does the second mitotic division occur in the egg?
after the first and before the third
During which main phase of the cell cycle do mitosis abd cytokinesis occur?
Mitosis and cytokinesis occur during the mitotic phase of the cell cycle.
Factors affecting cell radiosensitivity?
The greatest radiation effects will occur in cells having the 1) least maturity 2) least specialization 3) most mitotic activity, and 4) longest mitotic phase. ...so 1. Maturity of the cell 2. Specialization of the cell 3. Mitotic activity of the cell 4. Mitotic phase of the cell ( I am a radiology student, all this information came from my text book :) )
Where does photosynthesis usually occur in epidermis?
The epidermis of most plants is made of transparent cells that allow light into the mesophyll cells below them, which contain chloroplasts and are the site of photosynthesis. Additionally, the epidermis contains stomata, which are pores that allow for the exchange of gases with the atmosphere. This lets the plants take in carbon dioxide and release oxygen, as well as allowing for transpiration (evaporation), which ultimately helps to move water into leaves. Waters is also needed for photosynthesis.
What mitotic structures are present both in plant and animal cells?
All multicellular plants and animals, as well as fungi and protists, use mitotic cell division to develop from single cell organisms into organisms containing billions of cells. Mitosis continues in full-grown organisms replacing dying or repairing damaged cells. Throughout the human body, an estimated 25 million mitotic cell divisions occur every second in order to replace cells that have completed their normal life cycles. Some multicellular organisms rely on mitosis for asexual reproduction, and it is the only reproduction method used by many single-celled organisms.
Where else in a plant might you find a large amount of mitotic cell divisions occurring?
Mitotic cell division refers to the division of the mother cell into two daughter cells. In plants, a large amount of mitotic cell divisions occur in the terminal buds, shoot tips and in the vascular cambium.
What is skin epidermis?
The epidermis is a supuficial thin layer and is divided into three layers, The Malphigian layer, The Granular Layer and The Cornified Layer.4-5 layers of stratified squamous epithelial cells with lipid layer to preserve moisture. Thin skin is made of 4 layers the stratum germanitivum, the stratum spinosum, the stratum granulosum, and the stratum corneum, thick skin has all these layers and an additional layer named the stratum lucidum.The epidermis is composed of the outermost layers of cells in the skinEpidermis is the outer layer of cells covering an organism, in particular.Your epidermis is the outer layer of your skin.Anything that is not your skin. Epidermis-- The uppermost layer of skin cells.The epidermis is the outer covering of a living thing or organism. On a human or animal, this basically means your skin. The epidermis layer covers the dermis layer of tissue.
When does the second mitotic division occur in the egg?
after the first and before the third
When does fertilization in mitosis occur?
Fertilization does not occur in mitosis. Fertilization signals for the start of mitotic division in embryos.
When does cytokinesis occur in cell cycle?
It usually occurs in telophase of mitosis and in the M (mitotic) phase.
How many cell divisions occur in a 24 hours in adult human beings?
About 2 trillion cell divisions occur in an adult human every 24 hours.
During which main phase of the cell cycle do mitosis abd cytokinesis occur?
Mitosis and cytokinesis occur during the mitotic phase of the cell cycle.
What divisions existed among allies troops in Europe?
Most divisions that occur among the allied troops are divisions related to race, gender, and equality.
How many divisions in meiosis?
Two successive nuclear divisions occur, Meiosis I (Reduction) and Meiosis II (Division)
What are the two disjunctionsthat can occur?
Mitotic or meiotic, depending on whether ordinary cell division or gamete production is involved.
When DNA divides what event must occur if a nucleus containing this molecule undergos mitotic cell division?
Suwoo
When does the first mitotic division occur in zygotes?
You remain as a single cell for about 1/2 hour
