Is there an increase in the size of cells during cleavage?
During cleavage, the size of individual cells does not increase; instead, the number of cells increases through rapid divisions. Cleavage divisions are characterized by the splitting of the zygote into smaller cells called blastomeres without significant growth in cell size. This results in a larger number of smaller cells as the embryo develops, leading to a process known as cellular compaction.
What process occurs during cellular development as the cells changes into a specific type of cell with specialized functions?

What process accrues during cellular development as the cell changes into a specific type of cell with specialized functions?
The process that occurs during cellular development as a cell transforms into a specific type of cell with specialized functions is called cellular differentiation. During differentiation, stem cells or progenitor cells undergo changes in gene expression, leading to the development of unique structures and functions tailored to specific roles in the organism. This process is regulated by various factors, including signaling molecules and the cellular environment, which guide the cell's fate and specialization. Ultimately, differentiation ensures that diverse cell types work together to maintain the organism's overall function and homeostasis.
What is the role of cytoplasm in development?
The cytoplasm plays a crucial role in development by providing a medium for cellular processes to occur, such as cell division and protein synthesis. It also contains various organelles, such as mitochondria and ribosomes, that are essential for cell function and growth. Additionally, the cytoplasm contributes to cellular differentiation and organization during development.
What processes results in only one of the haploid cells being viable?
During oogenesis, the process of female gamete formation, meiosis results in one viable haploid ovum and three polar bodies. The unequal cytokinesis during the two meiotic divisions ensures that most of the cytoplasm is allocated to the ovum, while the polar bodies, which are smaller and contain little cytoplasm, eventually degenerate. This process maximizes the resources available for the development of the single egg, enhancing its chances of successful fertilization and development.
What is the phase of development during which cellular divisions result in a smaller and smaller cells?
Blastocyst

What are some unequal cytoplasmic divisions are characteristic of?
Unequal cytoplasmic divisions are characteristic of oogenesis, where a large ovum receives most of the cytoplasm while smaller polar bodies are formed, which eventually degenerate. Unequal divisions also occur during embryonic development in organisms such as nematodes, where specific cells receive an unequal distribution of cytoplasm to establish asymmetric cell fates.
The series of cellular divisions by which the zygote becomes a multicellular embryo is known as?
The series of cellular divisions by which the zygote becomes a multicellular embryo is known as cleavage. During cleavage, the zygote undergoes multiple rapid divisions without growth in between, leading to the formation of a blastula or blastocyst.
When does Growth and Development start?
Growth and development begin at conception when a sperm fertilizes an egg, forming a zygote. This process initiates a series of cellular divisions and differentiations that lead to the formation of tissues and organs. In humans, significant growth and developmental milestones occur during prenatal stages, infancy, childhood, and adolescence, each characterized by distinct physical, cognitive, and emotional changes. Overall, growth and development are lifelong processes that continue into adulthood.

Does a zygote undergo mitosis during the development of the embryo?
Yes, a zygote undergoes mitosis during the development of the embryo. After fertilization, the zygote divides through a series of mitotic divisions, leading to the formation of a multicellular structure known as a blastocyst. This process of cell division is essential for the growth and development of the embryo as it establishes the foundation for further differentiation and organ development.
What do cells need to do between divisions to make sure they dont get smaller?

What internal divisions did unions experience in the late 1800s and early 1900s?
Many unions experience divisions related to members being split over decisions regarding strikes, during the late 1800s and early 1900s. This resulted in large unions splitting into smaller ones.

Is NAD reduced or oxidized during cellular respiration?
NAD is reduced during cellular respiration.
