Is 12 cell embryo capable of implanting in uterus?
A 12-cell embryo, also known as a morula, is in the early stages of development but is not yet fully prepared for implantation in the uterus. Typically, implantation occurs after the embryo reaches the blastocyst stage, which usually happens around day 5 post-fertilization. At this stage, the embryo has developed a fluid-filled cavity and differentiates into an inner cell mass and an outer trophoblast layer, which are essential for successful implantation. Therefore, while a 12-cell embryo is an important step in development, it is not yet capable of implanting.
What is the function of basal cell and terminal cell in plant embryo development?
terminal cell : provide polarity to the embryo and embryo develops here.. (apical cell) basal cell : develops suspensor which anchors embryo to the endosperm and serve as a nutrient producer.
What is meant by the term embryo?
An embryo is the early stage of development of a multicellular organism, following fertilization of an egg cell by a sperm cell. It is characterized by rapid cell division and differentiation that ultimately gives rise to the tissues and organs of the organism.
Which process directly follows the zygote stage?
The next stage after the zygote stage is the embryo stage. During this stage, the zygote undergoes multiple cell divisions and starts to differentiate into the various cell types needed for development.
Why are Stem Cells important in the Developing Embryo?
Stem cells in the developing embryo are important because they have the ability to differentiate into various cell types, forming all the tissues and organs of the body. They play a crucial role in the early stages of development by giving rise to specialized cells that make up the embryo. This process is essential for proper growth and differentiation of cells to form a fully functional organism.
How is an embryo produced?
An embryo is produced through the process of fertilization, where a sperm cell from a male fertilizes an egg cell from a female. This results in the formation of a zygote, which then undergoes cell division and development to become an embryo.
What are the different stages of the embryonic development?
cell, zygote, embryo then fetus!
The embryo's development as seen here represents which processes in the development of any multicellular organism?
The embryo's development represents processes such as cell division, cell differentiation, and tissue morphogenesis, which are fundamental for creating the various cell types and structures necessary for an organism to develop properly.

What is an organism at an early stage of development?
embryo
What is the earliest stage of an embryo?
The earliest stage of an embryo is the zygote, which forms when a sperm fertilizes an egg. This single-cell stage begins the process of cell division and development into a multicellular organism.
Is embryo a gamete?
No, an embryo is not a gamete. A gamete is a specialized reproductive cell (sperm or egg) that fuses with another gamete during fertilization to form a zygote, which then develops into an embryo. An embryo is the early stage of development after fertilization.
What is the first step in the development of an embryo from a fertilized egg?
The first step in the development of an embryo from a fertilized egg is cleavage, where the cell begins to divide repeatedly without increasing in size. This process results in a multicellular structure known as a morula.
What type of cell division occurs in the embryo?
The type of cell division that occurs in the early embryo is called mitosis. Mitosis is a process where a single cell divides into two identical daughter cells, allowing for growth and development of the embryo.
What is the importance of cleavage in embryonic development?
Cleavage produces the number of cells needed for the future organisation of the embryo, shifts and compartmentalises the egg material and balances out the nuclear and cytoplasmic material. Development is initiated by cleavage.
During embryo sac formation what happens?
During embryo sac formation in plants, the megaspore mother cell undergoes meiosis to produce four haploid cells. One of these cells develops into the embryo sac, which contains the egg cell, central cell, and other supporting cells. The embryo sac is a crucial step in the development of the female gametophyte in plants.
