Cells and Processes

CLTs, Scientists, Pro and Eu, Cell Parts and Functions, Mitosis, Os and diff

What is the function of the nucleus? Holds the chromosomes
What is the function of the nucleolus? Make ribosomes
What is the function of the chromosomes? Responsible for growth and reproduction
What is the function of the Endoplasmic Reticulum? Transport proteins
What is the function of the Golgi Body? Package proteins
What is the function of the Ribosomes? Make Proteins
What is the function of the Cytoplasm? keep organelles from bumping into each other (fluid that fills the cell)
What is the function of the Vacuole? Store waste, material, and water
What is the function of the Lysosome? To clean the cell of old organelles and waste
What is the function of the chloroplast? Site of photosynthesis
What is the function of the Cell Membrane? Control what goes in and out of the cell
What is the function of the Cell Wall? Stiff outside covering on a plant cell that provided support
What is the function of the Mitochondria? Break down sugar for energy
How does the vacuole in the plant cell look different than in the animal cell? Plant cell vacuole is larger and only has one
What is the process that plant do to make sugar (food), that animal cells cannot do? Photosynthesis
What is on the outside of a plant cell, but not on an animal cell? Cell wall
What do eukaryotic cells have that prokaryotic cells do not? A nucleus
What are two examples of eukaryotic cells? Plants and animals
What are the two types of prokaryotic cell? eubacteria and archaebacteria
What are the prokaryotic cells that live in extreme environments? extremophiles- heat loving, salt loving, and methane making
What was Leuwenhoek's discovery? Single celled organisms in pond water
What was Hooke's discovery? Discovered and named cells
What was Pastuer discovery? Disproved Spontaneous Generation
What was Schleiden discovery? Discovered all parts of Plants are made of Cells
What was Schwann discovery? Discovered all parts of Animal are made of cells Cells
What was Virchow discovery? Discovered that cells come from pre-existing cells, but took this discovery from another scientist. (May have borrowed the idea :-)
What are the three parts of the cell theory? All living things are made of cells. Cells are the basic unit of life. All cells come from pre-existing cells.
Define Osmosis The movement of water from a high concentration to a low concentration through a semi-permeable membrane.
Define Diffusion The movement of molecules from a high concentration to a low concentration.
Define Semi-permeable Lets some things through but not others.
What is the stage of the cell cycle where the chromosomes copy? Interphase
What is the stage of the cell cycle where the chromosomes go to the center of the nucleus and look like spaghetti? Prophase
What is the stage of the cell cycle where the chromosomes line up and there is no longer a nucleus? Metaphase
What is the stage of the cell cycle where the chromosomes pull to opposite ends of the cell? Anaphase
What is the stage of the cell cycle where the two groups of chromosomes are grouped into two new nuclei? (Two nucleus in one cell) Telophase
What is the stage of the cell cycle where the cell splits into two daughter cells? Cytokinesis
What is the most common cell on Earth? Bacteria (Eubacteria)
What type of cell is Bacteria? Prokaryotic
What is the order of the stages for the cell cycle? Interphase, prophase, metaphase, anaphase, telophase, cytokinesis
What was Remack's discovery? Discovered that all cells come from pre-existing cells and actually did all the work for this discovery.
Which CLT is.. “My dog has become much less clumsy now that he is a year old.” Grow and develop
Which CLT is... "A giraffe uses its long neck to eat from the high branches of a tree." Adaptation
Which CLT is... "A hydra (pond creature) breaks off one of its tentacles and that tentacle becomes a new hydra." Reproduction
Which CLT is.. “Single-celled organisms live in the pond behind school.” Made of Cells
Which CLT is... “When that car pulled in the driveway, my cat ran to hide under the porch.” Respond
Which CLT is... "Mushrooms do not do photosynthesis, but they do decompose material for nutrients." Use and Obtain Energy
What is sexual reproduction? 2 parent organisms, offspring is a combination of the two parent's DNA, happens in multicellular organisms.
What is asexual reproduction? 1 parent organism splits into two identical daughter cells. Offspring are genetically identical. Happens quicker than sexual reproduction.
What is an advantage of asexual reproduction? Happens quickly
What is an disadvantage of asexual reproduction? What can injure or kill one cell (parent cell) can injure or kill the copies (daughter cells).
What is an advantage of sexual reproduction? Since offspring are combinations of the parents they can adapt and survive more situation.
What has to happen before a cell can divide? Duplicate (copy) the chromosomes (DNA)
What is an disadvantage of sexual reproduction? Takes longer than asexual reproduction.
What does unicellular mean? one celled or single celled
What does multicellular mean? many celled
What is the main difference between Eukaryotic and Prokaryotic cells? Eukaryotic cells have a nucleus, Prokaryotic cells do not
