Imagine a field of flowers; a field of flowers that are pollinated by basically three different pollinators. One pollinator, bee

s, attracted to short plants. Another, butterflies, prefer plants of medium height and a third pollinator, birds, visits only the tallest plants. Pesticide spraying kills many insect pests in the field of flowers but also wipes out the butterfly population. If the pollinator that preferred plants of medium height, the butterflies, disappears from the area, medium height plants would be selected against and the population would tend toward both short and tall, but not medium height plants. Such a population, in which multiple distinct forms or morphs exist is said to be polymorphic. This is also an example of ____________ selection.

sergey [27]

They are called parenchyma.

<h3>What is called Parenchyma?</h3>

The term "parenchyma" refers to the tissues that are employed for function in both plants and animals. Unlike "structural" tissues like wood in plants or bone in animals, this tissue is "functional," carrying out activities like photosynthesis in plants or information stored in the human brain.

A specific kind of ground tissue with thin cell walls and the capacity to expand and divide is referred to as parenchyma in plants. The majority of the cells in leaves, flowers, and fruits are parenchyma. In these formations, "structural" rather than "parenchymal" tissue makes up the hard, structural elements including bark, outer coatings, and major veins.

Can two purple flowered and yellow seeded parents produce offspring that have white flowers and green seeds?
Norma-Jean [14]
Yes, as long as both parents are heterozygous with recessive alleles of white flowers and green seeds. In this case, the ratio of chance of resulting purple flower yellow seed to white flower green seed will be 3 :1.
However, if both of the flowers are homozygous, which means they only have purple flower and yellow seeded allels, or even one is, the result is not possible, because we know that purple flowered and yellow seeds are dominant as both plants has these characteristics expressed.
