P
Which organelle contains the cell's DNA and controls gene expression?
Nucleus
Which organelle has ribosomes attached to its surface and helps make and process proteins?
Rough ER
Which selectively permeable structure controls what enters and leaves the plant cell?
Plasma membrane
Which organelle carries out photosynthesis?
Chloroplast
What region of the cell contains the organelles and is the site of many metabolic reactions?
Cytoplasm
Which region inside the nucleus produces ribosomal subunits?
Nucleolus
Which organelles help break down fatty acids and detoxify harmful substances?
Peroxisomes
Which protein network helps maintain cell shape and organize movement of materials inside the cell?
Cytoskeleton
What small membrane-bound structures transport materials within the cell?
Vesicles
plant cell needs to activate a gene for producing a specific enzyme. Which organelle contains the DNA where that gene is located?
Nucleus
Which structures are responsible for protein synthesis?
Ribosomes
Why can a plant cell maintain its shape when water enters the cell without immediately bursting?
The cell wall provides structural support and resists excessive expansion.
Which organelle carries out aerobic respiration and produces most cellular ATP?
Mitochondria
Which rigid structure surrounds the plasma membrane and provides support to plant cells?
Cell wall
A plant cell is producing large amounts of lipids for new membranes. Which organelle would be particularly active?
SER
A plant cell needs to increase its production of proteins. Which structure would help produce more ribosomes?
Nucleolus
Which organelle modifies, sorts, and packages proteins and lipids?
Golgi apparatus
A plant is placed in darkness for several days. Which organelle's main energy-producing process would be directly affected?
Chloroplast
Which large membrane-bound structure stores water and other substances in a plant cell?
Central vacuole
A plant cell cannot produce a particular protein even though the gene is present. Which structure may not be functioning correctly?
Ribosomes
vesicle needs to move from one part of the cell to another. Which cellular structure can provide tracks for intracellular movement?
Cytoskeleton
A plant cell is placed in a solution with a lower water potential than the cell. Which structure controls the movement of water across the cell boundary?
Plasma Membrane
A plant becomes dehydrated and its cells lose water. Which structure loses water and contributes to the loss of turgor pressure?
Central Vacuole
plant cell is breaking down fatty acids and producing potentially harmful substances that must be detoxified. Which organelle would be involved?
Peroxisome
A protein has been produced by the rough ER but must be modified and packaged before reaching its destination. Which organelle processes it?
Golgi Apparatus
