Cell Organelles

TermDefinition
cell membrane surrounds all cells, acts as a barrier between the inside of the cell and its environment. Regulates what gets inside and out of the cell
cell wall rigid structure surrounding the cell membrane in PLANTS; provides support and protection
nucleus control center of eukaryotic cells; stores the DNA
chloroplast organelle where photosynthesis happens in plants; contains the green pigment called chlorophyll
mitochondrion (plural is mitochondria) organelle where cellular respiration happens in ALL cells; the powerhouse
cytoplasm region between the cell membrane and nucleus; it includes the fluid (jelly) and all the organelles
vacuole stores nutrients, water, and wastes. Very large in plant cells.
1st part of cell theory All organisms are made up of 1 or more cells
2nd part of cell theory Cells are the basic units of all organisms
3rd part of cell theory All cells come from pre-existing cells
What is the difference between a plant and an animal cell's vacuole? Animal cells have many small vacuoles and plant cells have 1 large central vacuole
How can you tell the difference between a mitochondrion and a chloroplast in a diagram? A mitochondrion has folds (wavy lines) inside and a chloroplast has stacks inside
Prokaryote Unicellular organism with no nucleus and the DNA floats around the cytoplasm
Eukaryote More complex organisms with more organelles including a nucleus
True/False- You should determine if a cell is plant or animal by its shape and color. False
How should you determine if a cell is a plant or animal cell? If it has chloroplasts, cell wall, or a large central vacuole, it is a plant cell
Chlorophyll Green fluid inside the chloroplasts that trap sunlight for photosynthesis
True/False- Muscle cells will have more mitochondria. True because muscle cells require a lot of energy
