Big Ideas about Cells (according to our Lobster Team)
All living things are made of at least 1 cell.
Our bodies are made of millions of cells.
Most cells are microscopic.
There are many different types of cells.
Plant and animal cells are not the same (shape, ways to obtain energy, organelles).
Plant cells use energy from the sun to make food.
Animal cells get energy from other organisms.
A cell has many parts to it called organelles.
Each organelle have a special function that helps the cell survive.
The nucleus is like a control center of a cell.
Not all cells have a nucleus.
The mitochondria produce energy for a cell.
Cells move water (osmosis) and particles (diffusion) in and out of their selectively permeable membrane to reach a steady state (homeostasis).
Every cell has DNA.
Each of our cells contain an exact copy of our own DNA.
Cells have to be able to grow and reproduce.
Cells reproduce through mitosis, which has 6 stages.
Scientists owe much of what is known about cells and the way they behave to Henrietta Lack and her cells.
Most people have precancerous cells.
Cancer cells divide rapidly and uncontrollably.
