A primary cell cannot be recharged whereas a secondary cell can be recharged. In a primary cell chemical reaction is irreversible whereas in a secondary cell chemical reaction is reversible. ... A primary cell is light and less expensive whereas a secondary cell is heavy and expensive.
Primary cells are non-rechargeable batteries that are designed for single use, while secondary cells are rechargeable batteries that can be reused multiple times by recharging. Primary cells tend to have a higher energy density but cannot be recharged, while secondary cells can be recharged but may have a lower energy density.

Compare and contrast Primary oocyte and secondary oocyte?
Primary oocytes are diploid cells that have undergone DNA replication but are arrested in prophase I of meiosis, whereas secondary oocytes are haploid cells resulting from the division of primary oocyte after completing meiosis I. Secondary oocytes are arrested in metaphase II and are released during ovulation, while primary oocytes are present in the ovaries prior to puberty.
How do plants that lack a secondary growth increase girth?
Plants that lack secondary growth increase girth through primary growth, which involves cell division and expansion in the primary tissues of the plant (such as the primary xylem and phloem). These plants rely on the activity of their apical meristems to produce new cells that allow for a limited increase in girth over time.
Why is it essential that the primary stain and the counterstain be of contrasting colors?
Using contrasting colors for the primary stain and counterstain helps differentiate between different types of cells or structures under the microscope. This contrast makes it easier to visualize and distinguish between different elements within a sample, aiding in the identification and analysis of the specimen.
What is the difference between primary and secondary nondisjunction?
Primary nondisjunction occurs during meiosis when homologous chromosomes fail to separate, leading to abnormal chromosome numbers in daughter cells. Secondary nondisjunction happens later in development when a previously normal cell undergoes a mitotic division with faulty chromosome separation, resulting in abnormal chromosome numbers in daughter cells.
Do growth plates lie between primary and secondary ossification centers?
Yes, growth plates (also known as epiphyseal plates) are located between the primary and secondary ossification centers in long bones. They allow for longitudinal bone growth by producing new cartilage cells that are eventually replaced by bone tissue. Once growth is complete, the growth plates ossify and the bone stops growing in length.
What are Primary cell and secondary cell?
Primary cells can't be recharge. Secondary cells are rechargable.
Give example of primary secondary cells?
A primary cell can't be recharged, for example am ordinary 'D' cell, while secondary cells are rechargeable, e.g. one of the cells in a car battery.
What are the structure action and defects of primary and secondary cells?
PRIMARY CELLS: Are the cell which current is produced as a result of non-reversible chemical changes talking place between the various components of the cell. SECONDARY CELLS: These are cells whose chemical actions can be reversed by driving a current through them in a direction opposite to the current they supply. Such cells can therefore be recharged and used for a long time.
Are the rechargable batteries used in torches primary or small secondary cells?
Rechargeable batteries used in torches are considered secondary cells because they can be recharged and reused multiple times. Primary cells, on the other hand, are single-use batteries that cannot be recharged.
Lymph Nodules can be either Primary Nodules or Secondary Nodules?
Yes, primary nodules don't have germinal centers(active B cells) while secondary nodules do.
Compare and contrast Primary oocyte and secondary oocyte?
Primary oocytes are diploid cells that have undergone DNA replication but are arrested in prophase I of meiosis, whereas secondary oocytes are haploid cells resulting from the division of primary oocyte after completing meiosis I. Secondary oocytes are arrested in metaphase II and are released during ovulation, while primary oocytes are present in the ovaries prior to puberty.
Where is the location of cambium in plant?
The cambium is a layer of actively dividing cells located between the xylem and phloem in vascular plants, mainly in the stems and roots. Its primary function is to produce new cells for secondary growth, resulting in the thickening of the plant body.
Why is it difficult to distinguish the boundaries between the liver cells but not of plant cells?
Plant cells are regular shaped but liver cells are irregular.
What is meat by primary and secondary growth in vascular plants?
The primary growth in vascular plants takes place with the differentiation of vascular tissue from parenchymatous cells and the secondary growth takes place when the intra-vascular and inter vascular cambium adds to the secondary phloem and secondary xylem.
What are the primary difference between prokaryotes cells and eukaryotes cells?
The main primary difference between prokaryotic and eukaryotic cells is that the prokaryotic cells don't contain a nucleus. The eukaryotic cells are also larger than the prokaryotic cells.
Is duracell battery a primary or secondary battery?
First off, a battery is what you get when you stick several cells together, so for the most common 1.5 volts the strictly correct answer is that they are cells, not batteries. The 9 volt rectangular thingies though, they are batteries. Primary vs secondary is about rechargeable or not. A primary is not rechargeable, so a Duracell would most likely be a Primary cell.
Do epidermis cells have a secondary cell wall?
No, epidermal cells do not have a secondary cell wall. The primary cell wall of epidermal cells is composed mainly of cellulose, hemicellulose, and pectin, providing support and protection to the cell. Secondary cell walls are found in specific types of cells, such as xylem cells in plants, for additional structural support.
