Living Things
The amount of characteristics of living things there are
What is 5?
All cells come from pre-existing these
What are Cells?
The watery substance found within cells
A diffusor performs this by releasing particles into the air
What is diffusion?
Microscopes cost a lot of this; talk about high-tech!
What is money?
Living things grow in size, reproduce, and are able to do this
What is repair themselves?
Cell theory states that cells are the basic unit of life, come from pre-existing cells, and are made up of at least one of these
What are Cells?
The cell membrane acts as a what by allowing certain objects to enter or exit the cell
What is a gatekeeper?
An example of osmosis would be placing wilted lettuce in this so it can absorb it and become like new
What is water?
This refers to how enlarged the appearance of an object is under a microscope
What is magnification?
What is energy?
The two basic types of cells are these
What are animal and plant cells?
These two organelles help animal cells to move; plant cells have no need for these!
What are cilia and flagella?
Cell membranes are this as they allow certain things, like water, to enter the cell
What is selectively permeable?
This type of microscope has more magnifying power than your typical microscope as it uses beams of electrons, hint-hint!
What is an electron microscope?
When the fire alarm goes off and everyone leaves the building, we are showcasing this characteristic
What is living things respond to changes in their environment?
These types of cells were the first to be seen under a microscope, no one should whine about this!
What are cork cells?
In a plant cell, the cell membrane is located behind this strong organelle
What is the cell wall?
When particles are diffused, they spread like this throughout their environment
What is equally?
Some of the downsides of electron microscopes are that they are expensive, are huge machines, and require a lot of this to be used properly
What is training?
The average housefly lives for two weeks, while a Galapagos turtle can live up to 180 years; that's a pretty long this
What is lifespan?
Each cell in the human body, and in all lifeforms, perform a specific what
What is function?
As plant cells get most of their energy from the Sun, they need this organelle to perform photosynthesis
What is a chloroplast?
Osmosis and Diffusion both involve this, which determines higher and lower levels of particles and where particles should move to next
What is a concentration gradient?
This organelle, often referred to as the 'powerhouse of the cell', can only be seen with an electron microscope
What is the mitochondria?
