Cleavage is the division or split
Another definition is the portion showing between a woman's breasts that is often supported by a bra.
An embryo is a human that is still forming inside the uterus of a woman.
No, the size of the embryo remains relatively the same during cleavage as cell divisions occur. Cleavage is the process of rapid cell division without growth, so the overall size of the embryo does not increase significantly.
Successive cell divisions convert the zygote into a multicellular embryo during cleavage. This process involves rapid cell divisions without overall growth of the embryo. Cleavage helps in increasing the number of cells and establishing the basic body plan of the embryo.
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.
After fertilization, the zygote undergoes cleavage, forming a multicellular embryo. The embryo then implants into the uterine lining and develops into a blastocyst. Gastrulation follows, creating the three germ layers that give rise to different tissues and organs.
The correct order of developmental sequence is: Fertilization -> Zygote -> Cleavage -> Blastula -> Gastrula -> Embryo -> Meiosis -> Adult.

Mitosis or cleavage
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.
During cleavage, the major visible change in the embryo is the rapid division of the zygote into smaller cells called blastomeres without significant growth in the overall size of the embryo. This process results in a multicellular structure known as the blastula, characterized by a hollow cavity called the blastocoel. The cleavage stage is crucial for establishing the foundational layers and organization of the developing embryo.
Cleavage typically begins shortly after fertilization, when the zygote undergoes a series of rapid cell divisions called cleavage. This process results in the formation of a multicellular embryo.
After fertilization, the zygote undergoes cleavage, forming a multicellular embryo. The embryo then implants into the uterine lining and develops into a blastocyst. Gastrulation follows, creating the three germ layers that give rise to different tissues and organs.

What kind of cleavage are you referring to? Cleavage could refer to a cleavage furrow during cytokinesis or to the splitting of cells in an embryo or to any other sort of separation. Please specify.
During the cleavage stage, the zygote undergoes rapid cell division without increasing in size, resulting in the formation of a multicellular embryo called a blastula. Cleavage also helps to establish the basic body plan of the organism through the distribution of cells into different regions.
