cells
movement of materials across a membrane that does not require energy from the cell
What is passive transport?
a rigid structure surrounding a cell, outside the cell membrane, that gives the cell support and shape
What is the cell wall?
the structure that forms the surface of a cell separating its contents from the outside world
What is the plasma membrane?
Which phrase is not an example of intercellular communication?
A.Bacteria share information about nutrients
B. Endocrine cells send hormones into blood
C. Ribosomes make protein
What is C ribosomes make protein ?
What time does homeroom start?
8:45
Which type of cell is a rose thorn?
What is eukaryotic plant?
membrane-bound organelles in eukaryotic cells in which cellular respiration takes place, using oxygen to break down glucose to carbon dioxide and water and putting the energy into a more readily usable form in ATP molecules
What is the mitochondria?
an organelle of some eukaryotic cells in which photosynthesis occurs, using the energy of light to make organic compounds from carbon dioxide and water
What is chloroplast?
a type of cell that has a membrane-bound nucleus and membrane-bound organelles
What is a eukaryotic cell?
What does the "E" in our "Bear Expectations" stand for?
What is
E- Engage in your Learning?
allows for the movement of materials across the membrane that requires an input of energy from a cell
What is active transport?
a protein-bounded pore that forms a direct connection of cytoplasm between the two different cells, and through which molecules can diffuse between the cells
What is a gap junction?
a stringy extension of the outside surface of a prokaryotic cell that attaches it to a surface or another cell
What is the pili?
a small, membrane-enclosed structure inside a cell, smaller than a vacuole, often containing chemical substances for transport to another place in or out of the cell
What is the vesicle?
a type of cell without a membrane-bound nucleus and without membrane-bound organelles, considered by scientists to be a more primitive type of cell than the more complex eukaryotic cells
What is a prokaryotic cell?
A flower is ready to become a fruit.
Where would the instructions be found?
What is Nucleus?
short, hairlike structures covering part or all of the surface of some eukaryotic cells, which move fluid over the membrane or move the cell through the fluid environment
What is cilia?
a molecule that matches only with a specific other molecule or type of molecule, the signal molecule, and that causes changes when the signal molecule binds to it
What is a receptor?
a space in a cell surrounded by a membrane, larger than a vesicle, in which substances are stored or in which specialized functions take place, such as the digestion of material in a food vacuole
What is the vacule?
How long should you wash your hands for to get rid of germs?
What is 20 seconds?
What type of communication coordinates actions within the cells?
A intercellular
B recepter
C Chemical Signal
What is
A) intercellular
?
whiplike structures of cells that, through their movement, exert a force on the fluid surrounding the cell, either moving the fluid past the cell or moving the cell within the fluid
What is flagella?
a small organelle, made of RNA and protein and found in both prokaryotic and eukaryotic cells, that forms proteins from amino acids
What is a ribosome?
A storage organelle of the cell. Some vacuoles help transport food molecules across a cell membrane.
What is the vacuole?
What does CAVA stand for?
California Virual Academies
