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.
During which main phase of the cell cycle do mitosis abd cytokinesis occur?
Mitosis and cytokinesis occur during the M phase (mitotic phase) of the cell cycle. This phase is characterized by cell division, where the cell replicates its DNA and divides into two daughter cells.
What is the period of time between the first and second meiotic divisions?
The period of time between the first and second meiotic divisions is known as interkinesis. Interkinesis is a brief interphase that occurs between the two meiotic divisions in which DNA replication does not occur.
When does the second mitotic division occur in the egg?
The second mitotic division in the egg typically occurs after fertilization by the sperm. This division takes place once the zygote has formed and involves further division of the replicated chromosomes to generate daughter cells with the full complement of chromosomes.
What mitotic structures are present both in plant and animal cells?
Mitotic structures present in both plant and animal cells include the spindle fibers, centrosomes, and chromosomes. These structures play key roles in ensuring the accurate segregation of genetic material during cell division.
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.
What are the divisions of the atmosphere primarily based on?
The divisions of the atmosphere are primarily based on temperature variation. The atmosphere is divided into layers such as the troposphere, stratosphere, mesosphere, thermosphere, and exosphere, each with its own unique characteristics. Temperature changes occur based on the altitude within these layers.
What divides the layers of the earth's atmosphere?
The layers of the Earth's atmosphere are divided based on temperature changes, with each layer having unique characteristics and composition. The main divisions are the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. These divisions are defined by significant temperature changes or boundaries where different physical and chemical processes occur within each layer.
When does cytokinesis occur in cell cycle?
It usually occurs in telophase of mitosis and in the M (mitotic) phase.

Waters is also needed for photosynthesis.
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.
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 criterion is used to divide earths atmosphere into layers?
Earth's atmosphere is divided into layers based on changes in temperature and composition with altitude. The layers include the troposphere, stratosphere, mesosphere, thermosphere, and exosphere, each with distinct characteristics and dynamics. These divisions help scientists study the different properties and processes that occur within each layer.
During which main phase of the cell cycle do mitosis abd cytokinesis occur?
Mitosis and cytokinesis occur during the M phase (mitotic phase) of the cell cycle. This phase is characterized by cell division, where the cell replicates its DNA and divides into two daughter cells.
What are the two disjunctionsthat can occur?
Mitotic or meiotic, depending on whether ordinary cell division or gamete production is involved.
