Questions and Answers

Match the term to its description, based on the images provided:

Colonial Organism = A group of identical cells living together. Multicellular Organism = An organism composed of different cells that perform different functions. Unicellular organism = An organism that consists of only one cell . Filopodia = Slender cytoplasmic projections that extend beyond the leading edge of migrating cells.

Match the structures with their potential functions in the pictured single-celled organism:

Flagellum = Motility Cell membrane = Regulates the transport of materials into and out of the cell. Cytoplasm = A gel-like substance holding the cellular organelles. Ribosomes = Synthesizes proteins.

Match each cellular structure with its most accurate description:

Cell Wall = Provides rigidity and protection to the cell. Cell Membrane = A selectively permeable barrier that regulates the passage of substances. Nucleus = The control center of the cell, containing the genetic material. Mitochondria = The powerhouse of the cell, responsible for energy production via cellular respiration.

Which type of reproduction best describes the process by which the colony multiplies, assuming each cell is capable of independent division?

<p>Binary Fission = Asexual reproduction resulting in two identical cells. Meiosis = The process of cell division that produces haploid gametes. Mitosis = A type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus, typical of ordinary tissue growth. Budding = A form of asexual reproduction in which a new organism develops from an outgrowth or bud due to cell division at one particular site.</p> Signup and view all the answers

Match the term with the description that best fits how these organisms might interact with their ecological environment:

<p>Autotroph = An organism that produces its own food using light, water, carbon dioxide, or other chemicals. Heterotroph = An organism that cannot produce its own food, instead taking nutrition from other sources of organic carbon, mainly plant or animal matter. Chemotroph = An organism that obtains energy by the oxidation of electron donors in their environments. Phototroph = Organisms that carry out photosynthesis to acquire energy.</p> Signup and view all the answers
