Potometer or transpirometer is used to measure the transpiration rate. It is a long glass tube, side tube at right angles. A plant shoot sample... View Article
Water uptake is due to transpiration and photosynthesis. Potometer or transpirometer is an apparatus or instrument using which the rate of... View Article
Phloem proteins or P-proteins are elements found in phloem sieve tubes in large quantities. They are involved in sealing off the sieve cell by... View Article
Stomata are prime structures for transpiration. The leaf and stem epidermis are supplied with many stomata. Stomatal transpiration is the... View Article
Different ions from the soil are transported actively into roots' vascular tissues. Water goes as per the potential gradient, increasing the... View Article
Following are the differences between guard cells and epidermal cells - Epidermal cells are irregularly structured while guard cells have a... View Article
Facilitated division or transport is the spontaneous passing of ions or molecules across a biological layer passing via particular transmembrane... View Article
When turgidity grows in two guard cells that surround each stomatal pore or aperture, the thin exterior wall bulges, forcing the inner walls into... View Article
At each of the poles of cells, a complete chromosome set comes together. To create two new nuclei, a membrane is formed around each chromosome... View Article
During prophase, chromosomes condense into X-shaped structures. Each of the chromosomes comprises two sister chromatids that have identical... View Article
Meiosis reduces the chromosome number by half. The diploid cell entering mitosis will divide, producing two diploid daughter cells. Diploid cells... View Article
Though mitosis and meiosis are different, there are a few similarities too. Listed below are the similarities - Both involve a diploid parent... View Article
In mitosis, cells divide forming two identical daughter cells. The daughter cells have a copy of every chromosome as a result, mitosis first... View Article
In mitosis, two daughter cells are formed from a single, parent cell. This cell division is important for the growth and replacement of worn-out... View Article
Mitosis is primarily involved in the division of the parent cell to produce two identical daughter cells. Mitosis divides the nucleus of the cell... View Article
Crossing over or chromosomal crossover involved the exchange of genetic content during the process of sexual reproduction between homologous... View Article
Chiasmata are structures forming between a pair of homologous chromosomes by the process of crossover recombination. It physically associates the... View Article
Meiosis starts with a diploid cell containing two copies of each chromosome known as homologs. The cell first experiences DNA replication, hence... View Article
During the process of meiosis II, the sister chromatids found within the two daughter cells separate resulting in the formation of four new... View Article
