PARTS OF A CELL

Summary
of Lesson
THE ORGANELLES
• Nucleus: The heart of the cell, directs activities, and stores DNA.
• Cell Membrane: It surrounds the cell and lets things go in and out.
• Cell Wall: The cell wall is only found in the plant cell. It protects the cell and
lets things go in and out.
• Cytoplasm: It is the jelly-like substance in the cell that suspends all the
organelles.
• Ribosomes: They are not surrounded by the membrane. They help assemble
compounds like protein.
• Lysosomes: They help break down nutrients and old cell parts. They are
common in animal cells, but rare in plant cells.
ORGANELLES CONTINUED
• Vacuoles: Vacuoles store water, food, waste, and other substances the cell
processes. Animal cells have several small ones, while the plant cell has a big
one.
• Golgi Apparatus: Golgi Apparatus receives protein then processes it.
• Chloroplasts: It is only found in plant cells. They absorb sunlight to make food.
• Mitochondria: It takes in oxygen and Glucose to make water, energy, and
carbon dioxide.
• Endoplasmic Reticulum: It is the pathway which materials can pass.
VOCABULARY
• Cell: The basic building blocks off all living things.
• Organelles: Apart of a cell that does a specific job.
• Nucleus: The heart of the cell and stores DNA
• Cytoplasm: It is the jelly-like substance that suspends the organelles.
MAIN IDEAS
• Every single living thing is made up of a cell.
• Some cells only have one cell like bacteria, yeast, algae, and amoeba.
Other cells have billions and trillions of cells like us the human.
• Cells split up to create more cells.
A multi-celled organism
A single cell organism
THE DIFFERENT BETWEEN ANIMAL AND PLANT CELLS
Plant cells
Animal cells
They have chloroplast which
makes photosynthesis.
Animals can’t make
photosynthesis so they eat
other animals or plants.
Plant cells have a cell wall.
Animal cells only have a
membrane.
They do not have a
microtubules.
Animal cells have a
microtubules.
Beyond the book
WHAT IS A MICROTUBULES
• Microtubules are the same as microfilaments.
• They are strong thick spirals of thousands of units.
• These units are made up of tubulin.
• They got their name from all the tubes.
• Microtubules and microfilaments are formed together to make a
cytoskeleton.
FAST FACTS
• If all the DNA in the cell were lined up in your body it would stretch around
the world 49 times!
• The biggest cell in the world could be seen with the naked eye.
• There are more bacterial cells in the body than human cells.
• Every minute 200 million cells in our body die.
• Laughing improves the ability for cells to heal.
