Emma Kowal's Project journal- Lab 2

  1. By using OneZoom, I was able to locate that the bittersweet nightshade is under the eukaryote section, more specifically plants, that within the potato family, there are 1648 species of nightshade. With bittersweet nightshade having the most common ancestry with Clokey's nightshade and solanum lyratum.

  2. Since all my observations were made in Quebec, for any to survive throughout the year, the species I observed had to adapt to survive the winters of Montreal. For example, my birch and maple observations are deciduous plants that overcome this lack of water by dropping their leaves each fall. Leaves are the location in which water evaporates from plants. After shedding their leaves, deciduous plants go dormant. But my pine family observation is an example of conifers that also adapted to prevent water loss. Their leaves, which look like needles, have thick, waxy coatings that reduce water loss from their surface.

  3. After some research, I found that Bittersweet nightshade, one of my ten observations, prefers full or partial sun and moist soil that is fertile. But it has adapted to be able to prosper in drier conditions and other sorts of soil. Even being reported to continue to grow after disaster strikes, like fires. This is because it can sprout from its base after being cut or damaged.

    Tracy Cheng - Leaves

    1. Boxelder Maple Leaf
      By using OneZoom, I was able to identify the location of a boxelder maple leaf. It was found under the eukaryotes section, which then led to plants, and eventually narrowed down to thirty different species of maple leaves. Within those thirty various species, the boxelder maple leaf species was then found in the same grouping as a rocky mountain maple leaf.

    2. All of the identified leaves found in the group project all shared one similarity. All leaves had a dermal tissue system with an outermost waxy layer called the cuticle (which is known as the epidermis). This is an adaptation to the environment because it serves as a protective barrier from its surroundings, especially ones where it may cause the structure of a leaf to be vulnerable, for example heavy rain or winds.
    3. The leaves on a locust tree
      The leaves appear very longitudinal and spine-like, which in my opinion is an ideal shape for a plant, especially in a wet environment. The long and thin shape allows water to run down the structure, rather than the water piling up and collecting on the surface, which may eventually cause the leaf to weigh down.

    Lisa Tsyhanok - Plants of Mount Royal

    1. White Snakeroot is in the Eudicots, amidst the flowering plants (Magnoliopsida) in the Plantae kingdom; more specifically, it is a Snakeroot (Ageratina) in the Daisy family (Asteraceae) in the Asterales order. White Snakeroot is phylogenetically very close to Stevia and Common Boneset.
    2. All of the observed species in the group project are adapted to thrive in a cooler climate; for example, the trees in the area hibernate during the winter while the smaller plants, who are unable to do that, leave seeds and roots in the ground which hibernate in their own way and come alive in the spring. This makes sense because all of these organisms were found in and around Mount Royal where it gets cold in the winter; so to survive there, they had to adapt to the cold.
    3. One unique adaptation that is specific to Goldenrods is that their fruit is a single-seeded cypsela which is covered in hairs so that the seeds can be spread by the wind. This is beneficial to them because it allows the seeds to be spread far from the original plant and without the help of another organism (i.e. a squirrel having to bring the fruit somewhere else).

    Bella Sidoti - Lab 2 Project Journal

    1. By using OneZoom, I was able to identify the phylogenic position of the Curly Dock (or Rumex Crispus) which I observed in Lab 2. The Curly Dock is one of 10 species in the Rumex transiens family, which is a part of the larger category of Docks. The Docks category is found under the Polygonoideae group, which is found under the Caryophyllales, which is under the Pentapetalae, which is under the large category of Eukaryotes.
    2. All of the observations I made were in the same area meaning that all of the species observed have to undergo certain adaptations according to their shared climate. The climate in Montreal is very cold in the winter months, which requires from the life in the area an ability to adapt to lower temperatures. An example of this is when trees, from which some of the leaves I observed in the lab were from, need to adapt to the weather changes, they will go dormant and slow down their internal processes in order to stay alive through the winter.
    3. One adaptation for the Dandelion (or Genus Taraxacum) which I observed during the lab, is that, when the weather gets colder, the dandelions will form a new rosette. This rosette is the leaf-like formation at the bottom of the Dandelion, which enables it to stay more stable and alive during the hard months of winter.

    Anna Beyea - Plants of Mt Royal

    1. Sensitive fern (Onoclea sensibilis)
      The sensitive fern is a part of the Onclea genus, a sub division of the polypodiophyta division in the Plantae Kingdom.
      In order to find this species on OneZoom, the pathway taken was that of the Eukaryotes, which specified into plants, then into land plants and eventually leading to ferns. This species is found in the phylogenic branch derived from the Onocleaceae family which includes the common ancestors Onclea orientalis, Shuttlecock fern and Sensitive fern.

    2. As a result of the particularly cold winter climate of Canada, all of the species observed have adapted in order to survive through cold weather and winter freeze. Sensitive ferns adapt by covering itself in fronds throughout the winter whereas species such as the woodsorrel overwinter to keep their population abundant.
    3. Sensitive fern
      Sensitive ferns, unlike some northern ferns, are not evergreen. This species dies in the winter, but continues to have an abundant population in cold climates due to adaptations which allows for the plant to reproduce. This plant produces fronds which proceed to overwinter before allowing the release of spores (a form of asexual reproduction) in the spring, leading to the continuous presence of the plant in colder climates.

    Leatisha Ramloll - Leaves

    1. American Ginseng
      One unique adaptation for the American Ginseng is that it grows close to trees. This is because it needs the shade of the tree in order to survive since direct sunlight is harmful to it. As an additional bonus, the tree drops leaves which decay and create mulch allowing the plant to thrive.

    2. Common adaptation
      One adaptation that all observations have in common is that they are adapted to the harsh winters of the Montreal climate. For example, maple trees in the area will drop their leaves in order to conserve energy during harsh and cold winters.

    3. Black walnut- phylogeny placement
      The black walnut (scientifically referred to as Juglans Nigra) is part of the Dicotyledon class (plant/angiosperm that has a pair of leaves or cotyledon in the embryo of the seed) and the Juglandaceae (walnut) family.

    1. Euphorbia peplus
      Euphorbia peplus is native to most of Europe, northern Africa, and western Asia, often invasive to North America and other countries in temperate and sub-tropical regions.

    2. Common adaptation
      All of the observed species in the group have at least one shape part in them that prevents other organisms from eaten or destroying them. For example, Conyzinae (flower) has bristle in their plume; maple has teeth in their leaves; bees have a needle that contains venom. This makes sense if species do not have these aggressive "weapons" to protect them, they will be eaten and become distinct.

    3. Unique trait adaptation
      Euphorbia peplus has a green flower that is very identical to its leaves, which might prevent it from being eaten or destroyed by other animals.
