| Who gave us the term “cell”? | Robert Hooke |
| Who first viewed living cells under a microscope? | Anton van Leeuwenhoek |
| Who said all animals are made of cells? | Theodor Schwann |
| Who said all plants are made of cells? | Matthias Schleiden |
| What did Robert Virchow state? | Cells come from preexisting cells |
| List the 1 part of the cell theory. | All living organisms are composed of one or more cells |
| List the 1 part of the cell theory. | Cells are the basic unit of structure and function in an organism. |
| List the 1 part of the cell theory. | Cells come from preexisting cells. |
| List the three main parts of a cell. | cell membrane, nucleus, cytoplasm |
| What surrounds a cell and regulates what enters and leaves the cell? | Cell membrane |
| What is the gel-like substance found inside a cell? | cytoplasm |
| Cells that lack a membrane bound nucleus and organelles? | prokaryote |
| The __________acts like the structural support for the cell. | cytoskeleton |
| Give an example of prokaryote | bacteria |
| Cells that have a membrane bound nucleus and organelles? | eukaryote |
| Give an example of eukaryote | Plant or animal cell |
| What is the function of cilia and flagella? | movement |
| What is the cell membrane made of? | Phospholipid bilayer |
| Give the function for Nucleus | Controls most functions of cell |
| Give the function for Nucleolus | makes ribosomes |
| Give the function for Nuclear membrane | double layer of phospholipids that has nuclear pores that allow materials to enter and leave nucleus |
| Give the function for Chromosomes | made of DNA and proteins, contains your genetic information |
| Give the function for Centrioles | Anchor spindle fibers during mitosis and meiosis |
| Give the function for Cytoplasm | Gel-like substance found between cell membrane and nucleus aids in internal transportation and structure |
| Give the function for Cytoskeleton | provides support for cell |
| Give the function for Ribosome | produces proteins |
| Give the function for Endoplasmic reticulum | extensive system of internal membranes that move proteins and other substances through the cell |
| Give the function for Golgi apparatus | Shipping and handling; alters and prepares protein to be excreted from cell |
| Give the function for Mitochondria | powerhouse, provides energy to cell |
| Give the function for Vesicles | small, membrane bound sac that transports substances in cell |
| Give the function for Vacuoles | stores water or food |
| Give the function for Contractile vacuoles | forces water out of a cell |
| Give the function for Lysosome | Organelle that contains digestive enzymes |
| Give the function for RER | rough endoplasmic reticulum that has ribosomes that produce proteins to be excreted from the cell |
| Give the function for Free Ribosomes | provides proteins for the cell to use |
| Give the function for SER | Participates in the detoxification of toxins, builds lipids like cholesterol |
| List the three differences between plant and animal cells | Cell wall, Chloroplast, large central vacuole |
| Define the function of the cell wall and large central vacuole | to create turgor pressure within plant cell to help plant stand erect |
| What is found in Chloroplast | green pigment used in photosynthesis |
| What is found in Chromoplast | Contain colored pigments that may or may not take part in photosynthesis-orange,yellow, etc. that give plants their color |
| What is found in Leucoplast | store starch molecules |
