Cell Organelles
This organelle is known as the 'control center' of the cell.
What is the nucleus?
This is the basic unit of life according to cell theory.
What is the cell?
This structure gives plant cells their rigid shape but is not found in animal cells.
What is the cell wall?
This organelle controls what enters and leaves the cell.
What is the cell membrane?
These small structures are the site of protein synthesis in the cell.
What are ribosomes?
This tool allowed scientists to observe and study cells.
What is the microscope?
These organelles are found in plant cells but not in animal cells and are responsible for photosynthesis.
What are chloroplasts?
This jelly-like substance fills the cell and holds organelles in place.
This organelle converts energy stored in food to energy that the cell can use.
What is the mitochondria?
According to cell theory, all cells come from these.
What are pre-existing cells?
Plant cells usually have one large one of these, while animal cells have many small ones.
What is a vacuole?
This organelle stores genetic information and directs cell activities.
What is the nucleus?
This organelle packages and ships proteins and other materials throughout the cell.
What is the Golgi apparatus?
Before cell theory was established, scientists believed in this incorrect idea that living things could arise from non-living matter.
What is spontaneous generation?
Animal cells have these structures for breaking down waste, while plant cells usually do not.
What are lysosomes?
This network of membranes helps transport materials throughout the cell.
What is the endoplasmic reticulum (ER)?
This green organelle is found only in plant cells and is the site of photosynthesis.
What is the chloroplast?
This scientist is credited with first observing cells through a microscope.
Who is Robert Hooke?
Both plants and animal cells have this organelle that makes them a eukaryote.
What is a nucleus?
This organelle provides structure and support for the cell.
What is the cell wall?
