Question | Answer |
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 |
