These are structures that perform specific functions/jobs within the cell.
What are organelles?
100
This is the process of cell division/reproduction.
What is mitosis?
100
This organelle is only found in a plant cell and helps it to keep its structure.
What is the cell wall?
100
This is the normal number of chromosomes in a human cell.
What is 46 chromosomes?
200
This is made up of three statements:
1. All living things are made of one or more cells
2. Cells are the basic Units of living things
3. All cells come from existing cells
What is Cell Theory?
200
This organelle directs the cell's activities. It contains the cell's operating instructions and stores information that will be passed along to new cells.
What is the nucleus?
200
This is found in the cell's nucleus and is a material that stores coded information about how an organism will grow and develop.
What is DNA?
200
This is the thin outer layer of cells in a plant's roots.
What is the epidermis?
200
This is the number of chromosomes found in a human cell right before the cell divides in the process of mitosis.
What is 92 chromosomes?
300
This is the diffusion of water across a cell membrane.
What is osmosis?
300
These begin the process of making proteins.
What are ribosomes?
300
When mitosis begins, DNA coils tightly to form these bodies that can be seen on rod-shaped structures that look like the letter "X" when they are doubled.
What are chromosomes?
300
This moves water and minerals from the roots to other parts of a plant. It is part of the vascular system in all plants.
What is Xylem?
300
This is the name of the objects that pull the doubled chromosomes apart to opposite sides of the cell during mitosis.
What are spindles?
400
This is the movement of a substance from an area of its higher concentration to an area of its lower concentration.
What is diffusion?
400
This organelle maintains the internal environment of the cell and allows food to enter the cell as well as wastes to exit.
What is the cell membrane?
400
This is what happens to the chromosomes in the nucleus in the beginning stages of mitosis.
What is they double from 46 to 92 chromosomes?
400
This carries glucose (sugars) made in the leaves throughout the plant. Roots store some of these materials, usually in the form of starch.
What is Phloem?
400
This is what happens if a cell did not have a full set of chromosomes.
What is "it would not function properly?" or What is "it could die?"
500
Cells can be seen with the naked eye (without a microscope). True or False?
What is False?
500
This is the jelly-like fluid/substance containing the organelles. It lies between the nucleus and the cell membrane.
What is cytoplasm?
500
This is the final stage of mitosis.
What is getting two cells out of one?
500
Name the two types of plants and how they differ.
What are Angiosperms (plants that have seeds) and Gymnosperms (plants that have blade-like leaves or needles)?
500
This is the part of the cell that disappears (temporarily) during the process of mitosis.
