Which organelle in the egg may make human cloning impossible?
The mitochondria in the egg contain their own DNA, separate from the cell's nuclear DNA. This mitochondrial DNA can affect the development of the cloned embryo. If the cloned embryo contains donor egg mitochondria, it may lead to mitochondrial diseases and complications in the embryo, making human cloning more difficult.
What does an egg contribute to the embryo that a sperm cell does not?
An egg contributes the majority of the genetic material needed for the embryo to develop, including the mitochondria for energy production. In contrast, a sperm cell provides only half of the genetic material necessary for embryo formation.
What does an egg contribute to the embryo that sperm does not?
An egg contributes the majority of the genetic material (chromosomes) needed for the embryo, as well as organelles like mitochondria for energy production. Sperm only provides genetic material.
What does a sperm cell contribute to an embryo?
A sperm cell contributes half of the genetic material needed for the embryo, including the father's DNA. Additionally, the sperm cell's mitochondria are typically discarded during fertilization, so the embryo mainly relies on the egg cell for its cellular organelles.
Why are mitochondrial diseases exclusively inherited from the mother?
Mitochondrial diseases are exclusively inherited from the mother because mitochondria, the energy-producing structures in cells, are passed down from the mother's egg cell to the offspring. Sperm cells do not contribute mitochondria to the embryo, so any genetic mutations in the mitochondria will only be inherited from the mother.
What is the smallest organized unit in the body?
embryo
Where do you get your mitochondria from?
Mitochondria are inherited from the mother through the egg cell. When a sperm fertilizes an egg, the sperm's mitochondria are typically destroyed, so the mitochondria in the resulting embryo come exclusively from the mother.
Does the egg destroy the sperm's mitochondria?
No, the egg does not destroy the sperm's mitochondria. During fertilization, the sperm cell's mitochondria are typically destroyed, as the egg provides the necessary energy-producing organelles for the developing embryo.

In which trimester does the following occur A sac called a placenta forms around the embryo and is connected to the embryo with an umbilical cord.?
first

What is an embroyo?
An embryo is the early stage of development of a multicellular organism. In humans, the embryo is formed during the first eight weeks of gestation following fertilization of an egg by sperm. The embryo undergoes rapid cell division and differentiation to form the basic structures of the body.
What is the second organ to develop in the embryo?
The heart is the second organ to develop in the embryo, following the development of the neural tube. It starts to form and beat by about the third week of gestation.
What does the egg cell contribute to an embryo?
The egg cell contributes half of the genetic material (DNA) needed to create a new organism. It also provides organelles, such as mitochondria, that are essential for cellular functions in the developing embryo. Lastly, the egg cell plays a role in initiating cell division and guiding the early development of the embryo.
