Why do plant need food
erma4kov [3.2K]

Answer:

They need food in order to gain the initial energy they need.

Explanation:

Plants unlike humans don't get food by primary sources (aka, hunting). instead they retrieve their food from the suns rays. Without the suns rays they are able to convert this energy into glucose for themselves, and will essentially die because they do not have that source of food to give them the energy they need to survive.

Which of the steps in this sequence of events is an example of mitosis at work?
taurus [48]
<span>The bruise slowly disappears as the arm heals.

</span>
<span>The two identical daughter cells resulting from mitosis and cytokinesis are identical in the following ways:1. Mitosis occurs when the nucleus of the cell divides into two identical nuclei, each with the same type and number of chromosomes. The cell's DNA is duplicated during this phase. Sometimes the cell's DNA isn't copied properly resulting in cancer-type cells. 2. Cytokinesis is when the cytoplasm divides into two identical daughter cells. Each cell is genetically identical and both are a similar size.

Explain the process of cross-pollination.
Anna007 [38]

Cross pollination is the transfer of pollen of different species to stigma of different species of plants.

Cross pollination results in healthy, viable and diverse plants.

Mendel observed that traits could either be dominant or recessive.

Blended traits or incomplete dominance is the condition in which dominant allele could not produce its trait alone instead blending with recessive allele takes place giving new phenotype to progeny.

Explanation:

In cross pollination pollen transfer takes place from anthers to stigma. In Mendelian genetics the anthers of the plant was removed because it has both male and female parts on same plant so that self pollination does not take place.

The importance of cross pollination is that it creates diversity in the plant species since the traits having different alleles are combined to form the progeny plant. The offspring are healthier and high quality seeds are found.

Mendel observed that traits are either dominant or recessive in general.  It was observed that when homozygous parents were crossed, the progeny in F1 generation always had dominant trait. The recessive trait only appeared when F1 generation offspring were self pollinate.

Blended traits or incomplete dominance appear when alleles get blended and exhibit the traits in phenotype. The phenotype appeared will not be matching with either parents.

The example is a white coloured flower is crossed with red colour flower the resultant colour of the flower is pink. It shows that dominant allele red is not completely dominant and gets blended with white colour.
