Which organism spends most of its life cycle in a diploid state quizlet?

Which organism spends most of its life cycle as a diploid?

In a diploid-dominant life cycle, the multicellular diploid stage is the most obvious life stage, and the only haploid cells are the gametes. Humans and most animals have this type of life cycle.

How do organisms that spend most of their life cycle in a diploid state restore the diploid number of chromosomes?

If meiosis produces haploid cells, how is the diploid number restored for those organisms that spend most of their life cycle in the diploid state? … Sister chromatids separate in mitosis, while homologous pairs of chromosomes separate in meiosis II.

Why give platelet rich plasma PRP to a patient if they already have platelet derived growth factor in their bodies quizlet?

Why give platelet rich plasma (PRP) to a patient if they already have platelet derived growth factor in their bodies? It supplements native growth factor and increases the rate of healing.

What are the three types of life cycle?

A life cycle is a period involving one generation of an organism through means of reproduction, whether through asexual reproduction or sexual reproduction. In regard to its ploidy, there are three types of cycles; haplontic life cycle, diplontic life cycle, diplobiontic life cycle.

THIS IS INTERESTING:  Is it true that one member of each homologous chromosome pair comes from each gene?

What organisms are haploid?

Haploid gametes are produced during meiosis, which is a type of cell division that reduces the number of chromosomes in a parent diploid cell by half. Some organisms, like algae, have haploid portions of their life cycle. Other organisms, like male ants, live as haploid organisms throughout their life cycle.

Which type of life cycle shows zygotic meiosis?

The zygotic meiosis is found in the haplontic life cycle, in which meiosis occurs in zygote. The gametic meiosis occurs in some fungi, in which meiosis occurs in the cells of diploid organisms to form haploid gametes.

Are gametes haploid or diploid?

Gametes are haploid cells, and each cell carries only one copy of each chromosome. These reproductive cells are produced through a type of cell division called meiosis.

At what two stages in the human life cycle are diploid cells found?

Diploid cells are found in the adult human stage, and the zygote stage in the human life cycle.
