More cells
100
This part of the cell contains DNA and controls cell functions.
What is the nucleus?
100
What is a model?
Something that helps people understand something, like a phenomenon.
100
This is the smallest unit of life in all living organisms.
a cell?

What function does the nucleus have in cells?
control center of the cell...it directs metabolism and contains chromosomes made out of DNA
200
This gel-like substance inside the cell holds the organelles in place. Also, chemical reactions take place there.
What is the cytoplasm?
200
Why would you revise a model?
To update it based upon new evidence.

When does diffusion stop?
When it stops, does all movement stop?
When the concentration is balanced.
No, there is always movement, but it is working to maintain the balance, so it slows.

What is the liquid within a cell where metabolism occurs?
cytoplasm
300
Known as the "powerhouse" of the cell, this organelle produces energy.
What is the mitochondria?
300
What are the functions of the cell membrane?
To protect the cell.
To let things in and out.
300
Name the 3 major components of cell theory.
1. all organisms are made from cells
2. cells are the basic unit of life
3. cells come from preexisting cells that have multiplied

Explain concentration.
Concentration refers to the amount of a substance in a given space. When there's a higher concentration of a substance in one area compared to another, the substance will tend to move from the higher concentration area to the lower concentration area. This movement helps to balance things out.
400
This part of the cell acts as a protective barrier, controlling what enters and exits the cell.
What is the cell membrane?
400
What is metabolism and why is it important?
1. homeostasis (balancing act) is essential for survival.
-regulate water
-temperature can be a factor
-etc.
400
Why are cells small?
Cells are small to maximize their efficiency in exchanging materials, diffusing molecules, and communicating between the nucleus and the cytoplasm. This allows cells to function properly and maintain homeostasis.
400
Why is diffusion important?
This process is crucial for cells to get the nutrients they need and to get rid of waste products. Smaller cells are more efficient at diffusion because they have a larger surface area relative to their volume, allowing for faster exchange of materials.
500
Found in plant cells, this organelle is responsible for photosynthesis
What is the chloroplast?
500
What are the 6 things that determine that something is alive?
1. genetic material
2. growth
3. stimulus response (plant/light; animal/movement)
4. Requires energy
5. Homeostasis
6. Made of cells

Label the microscope

Explain diffusion
In cells, it's how tiny particles, like oxygen or nutrients, move from where there's a lot of them to where there are fewer.
