What are the name of different stages that the fertilized egg undergoes before it is born?
The fertilized egg undergoes several stages before birth, including the zygote stage, where fertilization occurs; the cleavage stage, characterized by rapid cell division; the blastocyst stage, where the embryo implants into the uterine wall; and the embryonic stage, which involves organ development. Following this, the fetus stage begins, lasting until birth. Each stage is crucial for proper development and growth.

What is a fertilized oocyte called?
A fertilized oocyte is called a zygote. This single cell is formed when a sperm cell successfully fertilizes an egg cell, combining their genetic materials. The zygote undergoes several divisions and developmental stages before eventually forming an embryo.
How does an embryo develop from a fertilized egg?
After fertilization, the fertilized egg undergoes cell division to form a blastocyst. The blastocyst then implants into the uterus and develops into an embryo. Over time, the embryo goes through various stages of development, including the formation of different tissues and organs, until it eventually becomes a fetus.
What three stages of development does fertilized egg go through before birth?
The zygote develops first into an embroy and then into a fetus
What is the organism in its early stages of development especially before it has reached a disgtinctively recognizable for?
The organism in its early stages of development before it has reached a distinctively recognizable form is called an embryo. The embryo undergoes various stages of growth and differentiation before it develops into a more recognizable form of the organism.
Through the development stages exhibited by different mollusks vary a generalized life cycle for mollusks can be described by which order of the developmental stages?
Fertilized egg, trochophore, veliger, adult
What are the developmental stages that a human undergoes between fertilization and birth?
The developmental stages a human undergoes between fertilization and birth include: zygote, blastocyst, embryo, and fetus. During these stages, the fertilized egg undergoes cell division, implantation into the uterus, organ formation, and growth. By the end of the fetal stage, the developing human is ready for birth.
What animal undergoes 2 stages life cycles?
chipamzees
What bug has three stages?
The bug that has three stages in its life cycle is the butterfly. It starts as an egg laid on a plant, hatches into a larva or caterpillar, then undergoes metamorphosis in a chrysalis or pupa before emerging as a fully developed adult butterfly.
What does the fertilized egg look like in the first stages of pregnancy?
like a cell
Where do periods come from?
Its the food that a fertilized ovum eats in the early stages of pregnancy if the ovum isn't fertilized then it leaks out because you don't need it
What is the sequence of prenatal development?
Prenatal development occurs in three main stages: the germinal stage (first two weeks after conception), the embryonic stage (weeks 3-8), and the fetal stage (weeks 9-birth). During these stages, the fertilized egg undergoes cell division, differentiation, and organ formation, leading to the development of a fetus.
What is the process of fertilization and development of marine leech eggs?
Marine leech eggs are fertilized externally when a male releases sperm near a female's eggs. The fertilized eggs develop into larvae, which hatch and go through several stages before becoming adult leeches.
