a living thing
What are organelles?
store food for the cell
make energy for the cell
protect the cell from invaders
parts that make up a cell
What is the cell membrane?
makes energy for the cell
gives instructions to the organelles

What is cytoplasm?
Jelly-like substance that organelles float in

Why does your body have different kids of cells?
We are made of trillions of cells. Each type of cell performs a unique and special function.
They are organized to keep us alive and healthy.
Cell - bone cell, Tissue - muscle, Orgain - skin, System - brain
To give instructions to the organlles
Give an example of cells, tissues, organs, and systems
red blood cells, white blood cells, skin cells, bone cells, muscle cells, nerve cells
organelles, cell membrane, cytoplasm, mitchondria, vacuoles, nucleus
Cell - bone cell, Tissue - muscle, Orgain - skin, System - brain
one or more cells, grows, changes, uses energy, responds, can reproduce
Give an example of different kinds of cells
respiratory, digestive, nervous
red blood cells, white blood cells, skin cells, bone cells, muscle cells, nerve cells
use energy, one or more cells, grows, changes, responds, can reproduce
protect the cell from invaders
How are cells, tissues, organs, and systems related?
Cells are called building blocks of life because they are basic structural and functional units of our life.
Living things respire, move, respond to stimuli, reproduce and grow, and are dependent on their environment.
There are 200 different types of cells in our body. Each type of cell performs a unique and special function.
Cells make up tissues, tissues make up organs, and organs make up organ systems. They are organized to keep us alive and healthy.
Who was Angon von Leeuwenhoek?
He invented calculus and was Master of the Mint in London.
He improved the early microscope, was the 1st person to see and describe bacteria.
He won a Nobel Prize in Physics for discovery of the photoelectric effect.
He discovered evolution, liked taxidermy. enjoyed unusual food, and suffered from ill health.
Why are cells call the building blocks of life?
Because they are basic structural and functional units of our life.
Because they are typically made of wood or plastic.
Because they are fun to gather friends together and play with.
Because they are shaped like Legos and click together to create animals.
