What are stem cells?

Stem cells are undifferentiated cells that have the ability to develop into various cell types.

What are the main types of stem cells?

The main types are embryonic stem cells, adult stem cells, and induced pluripotent stem cells.

What is pluripotent stem cell potency?

Pluripotent stem cells can differentiate into nearly all cell types except for extra-embryonic tissue.

What is totipotent stem cell potency?

Totipotent stem cells have the ability to develop into any cell type, including both embryonic and extra-embryonic tissues.

What are multipotent stem cells?

Multipotent stem cells can develop into a limited range of cell types related to a specific tissue.

What is the fate of the fertilized egg at 1 day post-fertilization?

At 1 day post-fertilization, the fertilized egg is a zygote.

What happens to the zygote at 3 days post-fertilization?

By 3 days post-fertilization, the zygote has developed into a morula.

When does the blastocyst form?

The blastocyst forms approximately 5-6 days after fertilization.

What are the key layers of a blastocyst?

The blastocyst consists of the inner cell mass (ICM) and the trophoblast.

What is pollination in plants?

Pollination is the transfer of pollen from the male anther to the female stigma of a flower.

What is fertilization in plants?

Fertilization occurs when the sperm cell from pollen merges with the ovule, leading to seed development.

What are the parts of a flower?

The main parts of a flower include the petals, sepals, stamens, and carpels.

What is a complete flower?

A complete flower has all four essential parts: stamens, carpels, petals, and sepals.

What is an incomplete flower?

An incomplete flower is missing one or more of the essential parts of a complete flower.

What occurs after fertilization of an ovum in humans?

After fertilization, the ovum undergoes cleavage, eventually forming a blastocyst, which implants into the uterine wall
