The answer would be bone marrow
Answer:
Cell biology is a branch of biology that studies the structure, function and behavior of cells. All living organisms are made of cells. A cell is the basic unit of life that is responsible for the living and functioning of organisms. Cell biology is the study of structural and functional units of cells.

Nature vs Nurture debate.
Explanation:
Development in human is inborn.The stages of development is dictated and directed by expression of genes encoded by the DNA.Therefore physiological and biochemical interpretations of these DNA dictates is known as human development. it is a fixed mechanisms which is fastest at childhood,and progressively slower at advanced stage.<u>Although environmental factors may influence this developmental stages, the exact mechanism of occurrence is constant and fixed.</u>
<u />
Nuture concept believe that, human development is as a result of societal and cultural factors in the environment, and the progression of the development is due to the influences of theses factors on human perception of life. Thus Human development is acquired through life exposure and experiences.They are therefore dynamic, and not static, but fluctuates based on level of exposure in the environment.
<u>However, both concept interacts with one another to ensure an holistic human development. Generally it is the interaction of the environment with genetic that explains the concept of natural selection and evolution of human race. </u>
<span>The answer is Haploid spores germinate to give rise to protonema, which later develops into a sporophyte.</span>
A protonema (plural: protonemata) is a
thread-like chain of cells that forms the earliest stage (the haploid phase) of a bryophyte life
cycle..
<span>A haploid gametophyte ( each of whose cells contains a fixed number of
unpaired </span>chromosomes) gives rise to a <span>diploid sporophyte</span>,.
Gametophytes produce haploid sperm and eggs which fuse to form diploid zygotes
that grow into sporophytes.
