what is difference between primary cell and secondary cell?
458199
The major difference between a primary cell and the secondary cell is that primary cells are the ones that cannot be charged but secondary cells are the ones that are rechargeable.

The second main difference is in the structure of the cell itself. Animal cells are smaller than plant cells and have a membrane around them that is flexible and allows molecules, gases and nutrients to pass into the cell. Plant cells are larger and in addition to a membrane they have a rigid cell wall.

A primary oocyte contains 46 chromosomes, while a secondary oocyte contains 23 chromosomes. A primary oocyte is produced after birth, while a secondary oocyte is produced before birth. ... A primary oocyte is the product of meiosis, while a secondary oocyte is the product of mitosis.

Answer: primary oocyte is a diploid cell formed in foetal ovary when the gamete mother cell,oogonia is arrested at prophase 1 of meisois. secondary oocyte is a haploid cell formed from primary oocyte that completed its first meiotic division,during puberty and produce the female gamete ova.

Primary means it comes directly from the researcher who conducted the study. The information is most useful when you need specific information on a field. Secondary research is defined as an analysis and interpretation of primary research. ... Secondary research is useful when you need broad information on a topic.

Advantages and Disadvantages of Primary Cells Allows experiments on human tissues which otherwise could not have been done in vivo. Primary cells take more time to grow than other cell lines and have limited growth potential even under optimal growth conditions and eventually senesce and die.

The difference between primary and secondary data in Statistics is that Primary data is collected firsthand by a researcher (organization, person, authority, agency or party etc) through experiments, surveys, questionnaires, focus groups, conducting interviews and taking (required) measurements, while the secondary ...

Key Differences Between Primary and Secondary Data Primary data is a real-time data whereas secondary data is one which relates to the past. Primary data is collected for addressing the problem at hand while secondary data is collected for purposes other than the problem at hand.

Basically, the key difference between cell organelles and cell inclusions is that cell organelles are living components and subcomponents of the cell that perform certain functions and act as cellular machines while cell inclusions are non-living chemical compounds and by-products of cellular metabolism that are ...

The main difference in alleles between parent cell and daughter cells is that in mitosis, alleles of parent cell and daughter cells are genetically identical whereas, in meiosis, they are genetically different. That means; genetic recombination occurs through chromosomal crossing-over during meiosis.

The key difference between primary and secondary standard solution is that primary standard solution has a high purity and less reactivity whereas secondary solution has a less purity and high reactivity. ... Standard solutions have accurately known concentrations and we prepare these solutions using standard substances.

Primary bone. Primary bone is the first bone tissue that appears in embryonic development and in fracture repair. ... The secondary bones have lower amounts of osteocytes so primary bone is much more easily penetrated by x-ray.

All cell walls contain two layers, the middle lamella and the primary cell wall, and many cells produce an additional layer, called the secondary wall. The middle lamella serves as a cementing layer between the primary walls of adjacent cells.

Plant cells have a cell wall and can make their own food. Animal cells have a cell membrane and can move. Both have a nucleus and organelles.

Cell growth refers to the increase in cell size (mass accumulation) while cell division describes the division of a mother cell into two daughter cells (1->2->4->8, etc.). Cell proliferation is the process of generating an increased number of cells through cell division.

Two daughter cells are the final result from the mitotic process while four cells are the final result from the meiotic process. For organisms that reproduce via sexual reproduction, daughter cells result from meiosis. It is a two-part cell division process that ultimately produces an organism's gametes.

The main difference is the way each respective treatment is processed. Primary treatment works on sedimentation, where solids separate from the water through several different tanks. In contrast, secondary treatment uses aeration, biofiltration and the interaction of waste throughout its process.
