Cell Homeostasis Review Flashcards
What is a Prokaryote?
organisms whose cells lack a nucleus and other organelles.
or an organism that has no nucleus
What is a Eukaryote?
an organism whose cells contain a nucleus within a membrane. or an organism that has a nucleus
What is a Specialized Animal Cell?
Act like the street sweepers to keep particles out of lungs.
What is a Specialized Plant Cell?
Pollen grains are highly specialized cells that are tiny and light, with thick cell walls to protect the cells contact.
How are the Cells of Multicellular organisms are specialized?
The Cells of Multicellular Organisms are specialized by different cell types playing different roles.
Describe Homeostasis
A single celled or unicellular organism does everything you would expect living things to do.
What is an Example of a Prokaryote
Bacteria or Blue-Green algae.
What is an Example of a Eukaryote?
Yeast or Algae.
What is a Group of similar cells that perform a particular function?
A Tissue.
What is a group of Tissues?
An Organ.
What is a group of Organs that work together to perform a specific function?
An Organ System.
The groups of the body’s cells create a system to divide labor among all the cells that allow the organism to maintain _
Homeostasis.
How do Cells respond to Chemical Signals?
A receptor to which the signaling molecule can bind.
What would most likely happen to a unicellular organism if it was exposed to a hypotonic solution for an extended period of time?
It would swell and then burst.
Chlorophyll is found in plant leaves and absorbs light from the sun to enable plants to perform photosynthesis. Magnesium is an important component of chlorophyll. The concentration of magnesium ions is higher in the root-hair cells of plants than in the soil. Which mechanism of ion uptake would best enable a plant to produce a steady supply of chlorophyll?
Active Transport.
