| Question | Answer |
|---|---|
| A cell is the smallest unit that is capable of performing life functions according to what theory? | Cell Theory |
| What made the observation and description of microscopic organisms and living cells possible? | Magnifying lenses and light microscope |
| What is the basic unit of life? | Cell |
| All living things are made of what? | Cells |
| Cells come from pre-existing cells according to what theory? | Cell Theory |
| Who invented the first microscope? | Anton Van Leeuwenhoek |
| Who was the first to see bacteria and protists? | Anton Van Leeuwenhoek |
| Who observed that cork has small rectangular boxes called cells? | Robert Hooke |
| Who stated that all living things are made of cells? | Theodor Schwann and Matthias Schleiden |
| Who said that all cells came from pre-existing cells? | Rudolph Virchow |
| What microscope creates vivid 3D images by bouncing electrons off a gold-coated sample? | Scanning Electron Microscope (SEM) |
| What microscope creates detailed images by bouncing electrons off a sliced sample? | Transmission Electron Microscope (TEM) |
| Give an example of a cell. | Amoeba Proteus |
| Give another example of a cell. | Plant Stem |
| Give one more example of a cell. | Bacteria |
| What are the two types of cells? | Prokaryotic and Eukaryotic |
| Which type of cell does not have structures and has few internal structures? | Prokaryotic |
| Which type of cell contains organelles surrounded by membranes? | Eukaryotic |
| What cell part controls movement in and out of the cell? | Cell Membrane |
| What cell part supports and protects plant cells and bacteria? | Cell Wall |
| What directs cell activities and contains genetic material? | Nucleus |
| What surrounds the nucleus and has two layers with openings? | Nuclear Membrane |
| What is made of DNA and contains instructions for the cell? | Chromosomes |
| What contains RNA and builds proteins? | Nucleolus |
| What is the gel-like material that contains hereditary material? | Cytoplasm |
| What moves material around the cell? | Endoplasmic Reticulum |
| What are the two types of Endoplasmic Reticulum? | Smooth and Rough |
| What makes proteins and floats around in the cytoplasm? | Ribosomes |
| What produces energy and breaks down fats and carbohydrates? | Mitochondria |
| What packages and moves materials within the cell? | Golgi Bodies |
| What transports undigested material to the cell membrane? | Lysosomes |
| What are membrane-bound sacs that help plants maintain shape? | Vacuoles |
| What contains green chlorophyll and does photosynthesis? | Chloroplast |
| What process produces two or more daughter cells? | Cell Division |
| Why do cells need to grow and mature before division? | To ensure each daughter cell has what it needs to survive |
| What are the two stages of cellular reproduction? | Cellular Growth and Maturation, and Cell Division |
| What is the repeated pattern of growth and division that occurs in eukaryotic cells? | Cell Cycle |
| What type of cell division occurs in prokaryotic cells? | Binary Fission |
| What phase of the cell cycle is where cells undergo most of their growth? | G1 Phase |
| What happens during the S phase? | Chromosomes are replicated |
| What happens during the G2 phase? | Chromosomes condense and prepare for division |
| What percent of the cell cycle does interphase take up? | Almost 90% |
| What takes up only 10% of the cell cycle? | Mitosis and Cytokinesis |
| What happens during Prophase? | Chromosomes become visible and the nuclear membrane breaks down |
| What forms from the centrioles during Prophase? | Spindle fibers |
| What happens during Metaphase? | Chromosomes line up across the cell’s equator |
| What attaches to each chromosome’s centromere during Metaphase? | Spindle fibers |
| What happens during Anaphase? | Sister chromatids are pulled apart to opposite sides |
| What is each chromatid considered after being pulled apart? | A single chromosome |
| What happens during Telophase? | Chromosomes uncoil and nuclear membranes reform |
| What happens to spindle fibers during Telophase? | They disappear |
| What happens during Cytokinesis? | Cytoplasm divides forming two identical daughter cells |
| What do the new cells have after Cytokinesis? | The same number of chromosomes as the original cell |
| Why is it necessary for the cell to grow before cell division? | To produce enough organelles and materials for daughter cells |
| What are the main events in the cell cycle? | Interphase, Mitosis, and Cytokinesis |
| What characterizes the G1 phase of Interphase? | Cell grows and duplicates organelles |
| What happens in the S phase of Interphase? | DNA is replicated |
| What happens in the G2 phase of Interphase? | Cell grows and prepares for mitosis |
