Scenario: You are a research scientist and are working with eukaryotic cells obtained from a newly discovered organism, Oviductu
Minchanka [31]

Answer:

  • Based on this information you come to the conclusion that you have been able to identify in these cells the structure of <em>microfilaments</em> or <em>actin filaments</em>.
  • <em>Oviductus oblatus</em> are indeed eukaryotic cells

Explanation:

In eukaryotic cells, the cytoskeleton is composed of three well defined filamentous structures: microtubules, microfilaments, and intermediate filaments. Each of these filamentous structures is a <u>polymer of proteinic subunits</u> united by weak, not covalent connections.

The microfilaments are the thinnest of the three structures. They have a <u>diameter of 7 nanometers</u> and are <u>composed of many proteinic monomers</u> united. This monomeric protein is called actin. Many monomers get combined to form a structure that assembles a double helix.

Due to the fact that these microfilaments are made of actin monomers, they are also known as actin filaments.

Actin filaments have directionality which means that their extremes have different structures.

In eukaryotic cells, genes that codify for actin microfilaments are highly conserved in all organisms, which is why <u>they are often used as molecular markers</u> for different studies.

Compare and contrast animal and plant bodys and cells
Paul [167]

The similarities plant and animal bodies and cells include:

  • Plant and animals bodies grow
  • Plants and animals bodies have definite shapes
  • Plant and animals bodies are covered by protective layers of cells
  • Plants and animals both have plasma membranes
  • Plant and animal cells contain organelles.

The differences plant and animal bodies and cells include:

  • Plant have rigid bodies while animals have soft bodies
  • Plants have leaves, branches and roots while animals have hands and feet
  • Plants cells have cell walls while animals cells do not.
  • Plant cells are rigid while animal cells are flexible.

<h3>What are plants and animals?</h3>

Plants are large eukaryotic photosynthetic living organisms found on the earth.

Animals are either multicellular eukaryotic organisms which lack the ability to manufacture their own food as plants do, but depend on plants and other animals for their food.
