Cell Theory and Misc
All living things are made of one or more _____.
cells
Who used a compound microscope to name the first cell?
Robert Hooke
A cell moves substances through its semi-permeable membrane so that it can maintain a balanced internal environment, which is called _____.
homeostasis
The cell _____ was represented by the framework of straws in our Bubble Lab, where the cell _____ was represented by the bubble solution that stretched between the straws.
wall, membrane
The process of _____ moved water into and out of the egg cell.
osmosis
Cells are the basic _____ of structure and function of all living things.
unit
What did the scientist observe under a microscope to see the first cells?
piece of cork
What process involves the movement of a substance from a higher concentration to a lower concentration?
diffusion
When we passed our finger or hand through the bubble film, we modeled the process of _____ , where substances pass through a membrane.
osmosis
What happened when the egg cell was placed into a hypertonic solution? Why?
egg cell shrunk, could die; higher concentration of water inside the egg, so it moved to where there was less water
All cells come from _____.
other cells
What type of microscope was made to increase the magnification of objects with beams of something other than light?
electron
Diffusion is a type of _____ transport because it does not require energy.
passive
When our bin of bubble solution represented a cell, we blew bubbles inside the solution making organelles inside of a _____ cell.
eukaryotic
What happened when the egg cell was put into the hypotonic solution? Why?
egg cell expanded, could burst; higher concentration of water in solution, so water moves into egg where there is a lower concentration of water
Cells, such as plant and animal, that have organelles surrounded by a membrane are called _____.
Eukaryotes or Eukaryotic cells
What does a TEM "transmission" microscope allow us to see?
the structures inside of a cell
_____ diffusion is a type of passive transport where protein channels are used to move some molecules across the cell membrane that can't move on their own.
facilitated
When we used thread to make an open circle where materials could pass through without energy, the open circle was a ____.
protein channel
What would happen to the egg cell if it were in a isotonic solution? Why?
stays the same; concentration of water is same inside and outside of the cell
Cells, including those of archaea and bacteria, do not have organelles that are surrounded by a _____ and are called prokaryotes or prokaryotic cells.
membrane
What does a SEM "scanning" microscope allow us to see?
surface of a cell
Cells use _____ transport to move substances against the concentration gradient (from low to high) when needed.
active
When we blew a bubble in the solution to represent a cell and used a string to make more bubbles, the cell was _____.
dividing, multiplying or reproducing
What processes would a cell use if it needed to bring something large into the cell or out of the cell. Name the processes in the correct order.
endocytosis, exocytosis
