Cell Theory
All plants & animals are made of ________.
Cells
This organelle is known as the “control center” of the cell.
Nucleus
This thick, rigid outer layer is found only in plant cells.
Cell Wall
This jelly-like material fills the cell and holds organelles in place.
Cytoplasm
This invention made the discovery of cells possible.
Microscopes
This part of the cell theory says that all cells come from these.
Pre-existing Cells
These structures are the “powerhouses” of the cell, providing energy.
Mitochondria
These small organelles help animal cells divide, but are not found in plant cells.
Centrioles
This organelle is used to give a plant cell its shape.
Cell Wall
If you were looking through a microscope and saw something moving and dividing, what could you guess about it?
It's alive, because it’s showing signs of life like movement and reproduction?
True or False: Cells are the basic unit of matter.
False
This organelle makes proteins for the cell.
Ribosomes
Large central versions of this organelle are found in plant cells for storing water.
Central Vacuole
This part of the ER is covered in ribosomes.
Rough ER
Imagine a cell suddenly lost all of its mitochondria. What would likely happen to it,?
The cell would lose its main energy source (ATP) and eventually die.
This scientist proposed that all cells come from other cells, completing the cell theory., was _________.
Rudolf Virchow
This organelle is found only in plant cells and captures sunlight to make food.
Chloroplast
Both plant and animal cells have this outer boundary that controls what goes in and out.
Cell Membrane
This organelle digests waste and old cell parts.
Lysosome
Why do you think animal cells don’t have chloroplasts?
Animals can’t make their own food — they have to eat plants or other animals for energy.
Name all three parts of the cell theory.
(1) all living things are made of cells, (2) cells are the basic unit of life, and (3) all cells come from pre-existing cells?
This organelle is responsible for packaging and shipping materials in the cell.
Golgi Apparatus
The presence of these organelles allows plants to make their own food.
Chloroplasts
This Organelle is only in a animal cell used for cell division and looks like a churro.
Centrioles.
Why is the cell theory important to scientists today, even though it’s very old?
It’s still true and helps explain all living things, from bacteria to humans?
