Chapter 7- Cells (Organelles) Flashcards
Organelles that occur in pairs and are important for cell division
Centrioles
An inflexible barrier that provides support and protects the plant cell
Cell wall
A double-membrane organelle with thykaloids containing chlorophyll; where photosynthesis takes place
Chloroplast
Projections from cell surfaces that aid in locomotion and feeding; also used to sweep substances along surfaces
Cilia
A framework for the cell within the cytoplasm
Cytoskeleton
A highly folded membrane that is the site of protein synthesis
Endoplasmic Reticulum
Projections that aid in locomotion and feeding
Flagella
A flattened stack of tubular membranes that modifies proteins and packages them for distribution outside the cell
Golgi Aparatus
A vesicle that contains digestive enzymes for the breakdown of excess or worn-out cellular substances
Lysosome
A membrane-bound organelle that makes energy available for the rest of the cell
Mitochodrion
The control center of the cell that contains coded directions for the production of proteins and cell division
Nucleus
A flexible boundary that controls the movement of substances into and out of the cell
Plasma membrane
Organelle that is the site of protein synthesis
Ribosome
