|---|---|---|---|---|---|
| What is the nucleus? | The control center or "brain" of the cell. Contains cell's DNA and gives instructions to produce proteins.
🗑
|
||||
| What is an organelle? | Tiny structures within the cell that perform specific functions.
🗑
|
||||
| What is the cell membrane? | The outer covering in the animal cell and the inside wall of the plant cell. Controls what enter and leaves the cell.
🗑
|
||||
| What is a cell wall? | Non-living material that surrounds the plant cell. Gives the cell structure and support.
🗑
|
||||
| What is cytoplasm? | Jellylike material found throughout the cell.
🗑
|
||||
| What are mitochondria? | Provide energy for the cell by breaking down sugar.
🗑
|
||||
| What is the nuclear membrane? | Surrounds the nucleus and controls the movement of material into the nucleus.
🗑
|
||||
| True or False. Part of the cell that provides energy for the cell is the cytoplasm. | False
🗑
|
||||
| True or False. The brain of the cell is the nucleus. | True
🗑
|
||||
| True or False. The combination of nutrients and carbon dioxide to produce energy and oxygen is called cellular respiration. | False
🗑
|
||||
| True or False. The part of the cell that controls what goes in and out of the nucleus is the cell membrane. | False
🗑
|
||||
| True or False. A single celled organism that we viewed under the microscope is an amoeba, which cannot move. | False
🗑
|
||||
| True or False. The food for the yeast was oxygen. | False
🗑
|
||||
| True or False. The waste product of cellular respiration is carbon dioxide. | True
🗑
|
||||
| True or False. The control for the BTB was cup 8. | True
🗑
|
||||
| True or False. A plant cell and a yeast cell both have a cell wall. | True
🗑
|
||||
| True or False. The BTB turns red in the presence of carbon dioxide. | False
🗑
|
||||
| True or False. All cells perform cellular respiration. | True
🗑
|
||||
| True or False. The amoeba and plant cell are part of a multicellular organism. | False
🗑
|
||||
| True or False. The cornstarch was not able to pass through the cell membrane because the iodine stayed yellow. | True
🗑
|
||||
| True or False. The carbon powder was modeling small cells. | True
🗑
|
||||
| True or False. The blue dye was modeling carbon dioxide. | False
🗑
|
||||
| True or False. The carbon pieces were modeling the large cells. | True
🗑
|
||||
| True or False. The function of the cell membrane is to control what goes in and out of a cell. | True
🗑
|
||||
| True or False. Large cells are more efficient than small cells in absorbing oxygen because there is more surface area to absorb the oxygen. | False
🗑
|
||||
| True or False. The size of particles is a determining factor if something will be able to pass through a cell membrane. | True
🗑
|
||||
| True or False. Plant cells have a regular shape, perform photosynthesis (make their own food) and perform cellular respiration. | True
🗑
|
||||
| True or False. Tiny structures within a cell are called organelles. | True
🗑
|
||||
| True or False. Lugol's solution or iodine turns pink in the presence of starch. | False
🗑
|

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
