Homework due tonight, please help!List the four types pf stem cell, give an example of each type, and explain how much each type can differentiate.

Answers

Answer 1

Answer:

Totipotent - Able to differentiate into any type of cell of the human body or of the placenta. For example, fertilized egg cells and the cells from the egg’s first few divisions.

Pluripotent - From totipotent cells, able to differentiate into almost any type of cell of the human body. For example, blastocyst cells

Multi potent - Can develop into more than one type of cell, but more limited than pluripotent cells. For example adult stem cells and cord blood stem cells

Unipotent - Can only differentiate in a single lineage. Skin cells are the most abundant type of these.

Answer 2

Answer: Embryonic stem cell- are harvested from the inner cell mass of the blastocyst seven to ten days after fertilization.

Fetal stem cell- are taken from the germline tissue that will make up the gonads of aborted fetuses.

Umbilical cord stem cell- umbilical cord blood cells contain stem cells similar to those found in bone marrow.

placenta derived stem cells- up to ten times as many stem cells can be harvested from a placenta as from cord blood

Adult stem cell- many adult tissue contain stem cells that can be isolated

This is where the genetic information is found in a eukaryotic cell? A) nucleus B) cytosol C) mitochondrial D) endoplasmic reticulum

Answers

Answer: A. Nucleus

Explanation:

The DNA from Eukaryotic cells is stored inside the nucleus of the cell. The Nucleus is where all the genetic information is stored; also it is the place where the DNA is replicated during Mitosis or cell division. Just a curious fact, Mitochondria also have DNA on their interior.

In eukaryotic cells, all the genetic information, in other words, the DNA is found in the nucleus, where its arranged in chromosomes. Therefore, the answer is A).

In the other hand, in prokaryotic cells, it isn't inside any special structure. Instead, it's just dispersed through the cytoplasm.
