Chapter 1 Starred Flashcards
What is a Cell?
Cell is the basic structural and functional unit of all living organisms.
What is a Lysosome?
Vesicles that contain substances that digest excess or worn out organelles and food particles.
What is Golgi Apparatus?
Flattened sack of membranes that modifies, sorts, and packages proteins into sacs called vesicles.
What is Endoplasmic Reticulum?
Membrane system of folded sacs and interconnected channels that serve as the site for protein and lipid synthesis
What is Chloroplast?
Organelles that capture light energy and convert it to chemical energy the process is photosynthesis.
What is Mitochondria?
Convert fuel (sugars) into usable energy.
What is Centrioles?
Organelles made of microtubules that function during cell division.
What is Microfilament?
Thin protein threads that help give the cell shape and enable the entire cell or parts of the cell to move.
What is a Microtubule?
Long, hollow protein cylinders that form a rigid skeleton for the cell and assist in moving substances within the cell.
What is Cytoskeleton?
Supporting network of long thin protein fibers that form a framework for the cell and provide an anchor for the organelles inside the cell.
What is Cytoplasm?
Environment inside the plasma membrane.
What is Exocytosis?
Secretion of materials at the plasma membrane.
What is Endocytosis?
Process by which a cell surrounds a substance in the outside environment enclosing the substance a portion of the plasma membrane.
What structures are only in Animal Cells?
Lysosome
Microtubules/ Centrioles.
