What is the highly vascular structure that acts as communication between the mother and the embryos?
The chorion is the outer membrane surrounding the embryo that is continuous with the placenta, the highly vascular structure that acts as a physical communication between the mother and the embryo.
What else can I help you with?
Do plants develop from embryo's?
Yes, all the vascular plants develop from embryos.
What are the key differences between a chicken embryo and a human embryo in terms of development and structure?
Chicken embryos and human embryos have key differences in their development and structure. One major difference is that chicken embryos develop outside the mother's body in an egg, while human embryos develop inside the mother's womb. Additionally, the structures of the two embryos differ, with chicken embryos having a yolk sac for nutrition and a hard shell for protection, while human embryos rely on the mother's placenta for nutrition and protection. Overall, these differences reflect the unique evolutionary adaptations of each species for embryonic development.
Do early chick and pig embryos have a similar structure and appearance?
The early embryos of all animals have a very similar appearance. This is no different for chicken and pig embryos.
What structure stores the embryos waste in an amniotic egg?
respiration
What Structure in mammalian embryos that develop into the brain and spinal cord?
Neural tube
What is the structure in mammalian embryos that develops in to the brain and spinal cord?
Neural Tube
What is the meaning of seed vascular plant?
A seed vascular plant is a type of plant that has vascular tissues (xylem and phloem) for transporting water and nutrients, as well as reproductive structures that produce seeds. These plants include gymnosperms (such as pine trees) and angiosperms (flowering plants), which make up a majority of plant species on Earth. Seeds provide a protective structure for plant embryos and help with dispersal.
What structure do chicken embryos have around them that human embryos do not?
Chickens have an actual shell. The shell along with the embryo is called an egg. Human embryos are inside a females' womb which is made of skin, not keratin like egg shells are.
What is the structure in mammalian embryos that develops into the brain and spinal chord?
The neural tube is the structure in mammalian embryos that develops into the brain and spinal cord. It forms from the ectoderm layer during development and gives rise to the central nervous system.
Difference between organogenesis and somatic embryogenesis?
organogenesis: -production of UNIPOLAR structure (shoot OR root PRIMODIUM) -vascular system CONNECTED to parent tissue somatic embryogenesis: - production of BIPOLAR structure (shoot AND root axes) - vascular system NOT CONNECTED to parent tissue
What has the author Edith Frederiks written?
Edith Frederiks has written: 'Vascular pattern in embryos with clefts of primary and secondary palate' -- subject(s): Blood-vessels, Cleft palate, Head, Human Embryology
What is the stage of the plant embryos in which the embryos are alive but not growing?
dormancy
