Who named cells after looking at cork?
Robert Hooke

Do prokaryotes have a nucleus?
No they do not.
100
This organelle converts chemical energy from food into ATP through cellular respiration.
mitochondria
100
Mitosis ensures genetic consistency by producing these types of cells.
Identical daughter cells
200
What is cytoplasm?
This substance is found inside all cells and helps carry out functions.

Who saw tiny living things in pond water?
Antonie van Leeuwenhoek
200
Give 4 examples of a eukaryote.
plant/animal/fungi/protist
200
Found only in certain eukaryotes, this double-membrane organelle contains thylakoids and its own DNA.
Chloroplast

What stage of mitosis is B?
Metaphase
300
Name two life functions that cells perform.
metabolism, reproduction, homeostasis, response to stimuli, adaptation and growth.
300
Name one part of the cell theory.
300
These cells lack membrane-bound organelles and compartmentalization.
Prokaryotic cells
300
In plant cells, this structure regulates turgor pressure and stores pigments, toxins, and water.
Central vacuole
300
During this mitotic phase, sister chromatids are pulled to opposite poles.
Anaphase
400
Name 3 things all cells have.
DNA, cytoplasm, and cell membrane.
400
In what ways did the invention and improvement of the microscope directly influence the development of the cell theory? Name at least two scientists and their specific contributions.
1. Robert Hooke came up with the term “cell.”
2. Anton van Leeuwenhoek used a more powerful single-lens microscope to observe “animalcules” (bacteria and protozoa), becoming the first to see living cells which were foundational for developing the idea that all organisms are made of cells.
400
Are bacteria prokaryotes or eukaryotes?
prokaryotes
400
This organelle contains hydrolytic enzymes and is more prominent in animal cells than plant cells.
Lysosome
400
These cells are diploid and make up the majority of an organism’s body.
stomatic/body cells
500
What is C?
Mitochondria
500
What does the cell theory say about where cells come from?
All cells come from pre-existing cells.
500
These cells can carry out specialized functions due to their internal membrane system.
eukaryotic cells
500
This flattened organelle modifies, sorts, and packages proteins for secretion or membrane use.
Golgi apparatus/body
500
This diploid cell results from the fusion of two haploid gametes.
zygote
