If your professor desires you to make a phylogenetic tree of orchids and she provides you tissue from seven orchid species and one lily, then the most likely reason why she gave you the lily is for it to serve as an outgroup.

To add, in cladistics or phylogenetics<span>, an outgroup is a group of organisms that serve as a reference group when determining the </span>evolutionary<span> relationship among three or more monophyletic groups of organisms. The set of organisms under study that precisely allows the phylogeny to be rooted is called the outgroup and it is used a comparison point for the ingroup.</span>

Crop Characteristics

Potatoes produce a fibrous root system. These roots are at best no more than 24in long. Thus potatoes are shallow rooted compared to cereals for example, which can root to at least 47in depth. As a result, potatoes are often unable to exploit nutrients and soil moisture at depth within a soil profile.

While root growth occurs when soil temperatures are between 50 to 95˚F (10 to 35˚C), best, most active root development is at soil temperatures of between 59 and 68˚F (15 and 20˚C).

Leaf (haulm) growth occurs at temperatures of between 44.6 to 86˚F (7 to 30˚C) , but optimal growth is at around 68 to 77˚F (20 to 25˚C). Optimum temperatures for stolon growth are similar.

effects of soil temperature on root development
The potato tuber is an enlarged portion of the stolon. The initiation of this tuber is triggered by short day lengths (photoperiods), and involves growth hormones. The colder the soil temperature, the more rapid the initiation of tubers and the greater the number of tubers formed. The optimum soil temperature for tuber initiation is 59 to 68˚F (15 to 20˚C).

Under these conditions, the potato plant will have short stolons and shoots. Longer day lengths delay tuber initiation and favor the growth of the stolon and shoot. High temperatures also reduce tuber formation. Late varieties seem to be more sensitive to long day lengths or high temperature conditions.

Low nitrogen and high sucrose levels in the plant favor the formation of more tubers.

Once formed, tubers grow rapidly, reaching a maximum rate of up to 1,249 lb/ac/day in temperate climates. See figure below:

Physiological Aging

By planting sprouted seed, crop growth can be advanced. The magnitude of this response and its effect on increasing crop yield is related to the physiological age of the seed at planting.

Answer:

They can perform photosynthesis.

Explanation:

Autotrophs are organisms that can produce their own food, and heterotrophs are organisms that feed on other organisms. This means that the ameba and paramecium can eat only other microorganisms.

The euglena is not limited to this. Hypothetically speaking, if there were no other microorganisms around it (which is unlikely), the euglena would not die as long as it is exposed to sunlight. Thanks to chloroplasts, organelles that contain chlorophyll, it can perform photosynthesis - a process in which, with the help of sunlight, carbon dioxide, minerals, and water are used to synthesize food.
