The similarities between an onion and whitefish cells exist in the cell division process. Normally the basic process of mitosis cell division is similar for plant cells and animal cells, but there are fundamental differences that mark the mitosis of plant and animal cells. Basic similarities of onion cell and that of whitefish embryo cell is that in the four phase of mitosis namely, Prophase, Metaphase, Anaphase and Telophase occurs in similar way. In Prophase for both cells the chromatin condensed and in metaphase the chromatin aligns in the center of cell and kinetochores of chromosomes attached with the microtubules of spindle from opposite poles. In Anaphase stage, the chromatids from the metaphase plate are separated and shifted to opposite poles.. Finally at Telophase, the cell divides via cytokinesis. The fundamental difference between Onion cells and Whitefish cells can be found in the process of cytokinesis.

Answer from: neash19

Cell division is the process in which cell divides and give rise to daughter cells. The phases of cell division are studied to understand the process. The onion root tip and white fish cells are used to study the mitosis.

Cell cycle is composed of interphase, mitosis, and cytokinesis. The mitotic phase involves the production of two identical daughter cells having same number of chromosomes as parent cell. The mitosis constitute of prophase, metaphase, anaphase, and telophase stages.

The similarity in onion root tips and whitefish cells are:

The stages of mitosis are similar in both the cells. These cells are used to study mitotic division. These cells are rapidly dividing, which makes it easier to understand the process of cell division.

However, the cells differ in the cytokinesis process.

Therefore, the onion root tip cells and whitefish cells exhibit rapid division and are used to study mitosis.

Answer from: Quest

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.
