Organelles
This organelle is known as the "powerhouse" of the cell.
What is the mitochondrion?
It protects the cell and controls what enters and leaves.
What is the cell membrane?
Plant cells have this, which animals cells do not, to keep their shape rigid.
What is the cell wall?
The jelly-like substance inside the cell where organelles float.
What is the cytoplasm?
The size range of most animal and plant cells is measured in these units.
What are micrometers (microns)?
The "control center" that contains the cell’s DNA.
What is the nucleus?
This structure provides support and protection but is only found in plant cells.
What is the cell wall?
Unlike plant cells, animal cells have these to help with cell division.
What are centrioles?
This layer surrounds the nucleus and controls what goes in and out of the nucleus.
What is the nuclear membrane?
The first person to observe cells under a microscope.
Who is Robert Hooke?
This organelle packages and ships proteins and lipids inside the cell.
What is the Golgi apparatus?
This organelle converts sunlight into energy through photosynthesis.
What is the chloroplast?
This green organelle is absent in animal cells but vital for making food in plant cells.
What is the chloroplast?
This structure gives shape and support to animal cells by forming a network inside the cell.
What is the cytoskeleton?
Cells come from the division of this.
What are pre-existing cells?
The site where proteins are made.
What are ribosomes?
Responsible for breaking down waste and worn-out cell parts.
What are lysosomes?
This organelle is larger in plant cells than in animal cells.
What is the vacuole?
These tiny tubes help separate chromosomes during cell division.
What are spindle fibers?
This tool is essential for seeing cells and their parts.
What is the microscope?
This network of tubes and sacs helps transport materials within the cell and comes in rough and smooth forms.
What is the endoplasmic reticulum?
Maintains water balance and stores nutrients in a plant cell.
What is the central vacuole?
Animal cells can move this structure on their surface which plant cells lack.
What are cilia or flagella?
Some cells have this outer layer in addition to the cell membrane for extra protection, especially bacterial cells.
What is the capsule?
This theory states that all living things are made of cells.
What is the cell theory?
