Cells, History, & Microscopes
All living things are composed of....
What are Cells
This structure controls what substances come into and out of the cell
This organelle is the control center of the cell
What is the NUCLEUS
Energy is required to move substances in this type of transport
What is ACTIVE TRANSPORT
What is an element
If 1 microscope lens has a magnification of 10 & the other has a magnification of 40. What will the TOTAL magnification of the microscope be?
What is 400
This gel-like fluid surrounds the organelles in the cell
What is the cytoplasm
This organelle produces proteins
What are the RIBOSOMES
What is the movement of a substance from an area of high concentration to low concentration
What is DIFFUSION
What is in the CYTOPLASM
Who are the scientists that developed the cell theory?
This structure is a network of passageways, attached to the nucleus, that moves or carries materials away from the nucleus
What is the ENDOPLASMIC RETICULUM
This organelle breaks down food particles & worn out cell parts
What is the LYSOSOME
What is OSMOSIS
Proteins are made up of monomers called __________
What are AMINO ACIDS
1- All living things are composed of cells
2- Cells are the basic units of structure & function in living things
3- All cells are produced from other cells
What is the Golgi body
This organelle captures sunlight energy and makes photosynthesis possible
What is the CHLOROPLAST
The red blood cell will remain with the same size & shape.
Starch is an example of a...
What is a CARBOHYDRATE
What is the structure of the cell membrane called and how are its components arranged?
It is called the fluid mosaic model .
The cell membrane is made up of a phospholipid bilayer with a hydrophilic head that faces outwards and 2 hydrophobic tails that face inwards.
Plant & animal cells have a nucleus but bacteria does not.
Plant cells and bacterial cells have both a cell membrane and a cell wall unlike animal cells that just have a cell membrane
What is the storage compartment of cells called
What is the VACUOLE
What happens to a red blood cell when it is placed in a solution with a high salt concentration (hypertonic solution)
What happens to a red blood cell that is placed in a low salt or hypotonic solution?
The red blood cell will expand as water from the hypotonic solution will move into the red blood cell. If too much water enters the cell, it will burst.
