Parts of a Cell
Which organelle contains DNA?
The nucleus contains the DNA in eukaryotic cells.
What is the process by which prokaryotic cells divide?
Prokaryotic cells divide through binary fission.
Which scientist discovered and named cells?
Robert Hooke first discovered cells.
What type of cell has membrane-bound organelles?
Eukaryotic cells contain membrane-bound organelles.
True or False: all bacteria is harmful.
False! Some bacteria can be helpful.
Which organelle is the "powerhouse" of the cell?
The mitochondria generates energy for the cell.
What is the process by which eukaryotic cells divide?
Eukaryotic cells divide by undergoing mitosis.
Which scientist could see organelles because he built a better microscope than ever before?
Antoni van Leeuwenhoek built the best microscope at the time.
What type of cell must have a cell wall?
A plant cell must have a cell wall.
What do organism inherit from their parents that determine their traits?
Organisms inherit genes from their parents.
What does a vacuole store?`
The vacuole stores the cell's food, water, and waste.
What must the DNA do before the cell divides?
The DNA must replicate.
What did Hooke famously look at underneath a microscope?

Which type of cell is considered "simple"?

cells --> tissue --> organs --> organ system --> organism
What is the jelly-like substance that surrounds the organelles in a cell?
The cytoplasm surrounds the organelles in a cell.
Describe the process of binary fission.
The DNA strand copies itself and the cells splits, making two new cells.
Yes or no: Did the two scientists ever meet?
No, Hooke was too busy to meet with van Leeuwenhoek.
What kind of cell are bacteria and archea?
Bacteria and archea are prokaryotic.
In which organelle does photosynthesis occur?
It occurs in the chloroplast.
What is the full name for DNA?
deoxyribonucleic acid
Describe the process of mitosis.
1. DNA copies itself
2. Chromosomes line up
3. Identical halves are pulled apart to form the two new cells
What is the proper name for a nerve cell?
A nerve cell is called a neuron.
What makes plant cells green?
Chlorophyll, contained in the chloroplast, makes plant cells green.
