Organelles Flashcards
What is the function of the nucleus in a cell?
The nucleus serves as the control center of the cell, housing the cell’s DNA and coordinating activities such as growth, metabolism, and reproduction.
True or False: Mitochondria are known as the powerhouse of the cell.
True
Fill in the blank: The __________ is responsible for protein synthesis.
ribosome
What is the primary function of the endoplasmic reticulum?
The endoplasmic reticulum is involved in the synthesis, folding, modification, and transport of proteins and lipids.
Which organelle is responsible for detoxifying harmful substances?
smooth endoplasmic reticulum
What is the role of lysosomes in a cell?
Lysosomes contain digestive enzymes that break down waste materials and cellular debris.
Multiple Choice: Which organelle is involved in energy production? A) Ribosome B) Mitochondria C) Golgi apparatus
B) Mitochondria
What structure protects and gives shape to plant cells?
cell wall
True or False: The Golgi apparatus is involved in packaging and distributing proteins.
True
What is the function of chloroplasts?
Chloroplasts are responsible for photosynthesis, converting light energy into chemical energy in plant cells.
Fill in the blank: The __________ is a network of protein filaments that helps the cell maintain its shape.
cytoskeleton
Which organelle is known as the ‘suicide bag’ of the cell?
lysosome
What is the primary function of the plasma membrane?
The plasma membrane regulates the movement of substances in and out of the cell.
Multiple Choice: Which of the following organelles contains enzymes for digestion? A) Ribosome B) Lysosome C) Nucleus
B) Lysosome
What is the main purpose of vacuoles in plant cells?
Vacuoles store nutrients, waste products, and help maintain turgor pressure in plant cells.
True or False: Ribosomes can be found free-floating in the cytoplasm or attached to the endoplasmic reticulum.
True
What is the function of peroxisomes?
Peroxisomes break down fatty acids and detoxify harmful substances.
Fill in the blank: The __________ synthesizes lipids and detoxifies drugs.
smooth endoplasmic reticulum
What is the role of the cytoplasm?
The cytoplasm is the jelly-like fluid that fills the cell and contains organelles.
Multiple Choice: Which organelle is involved in modifying and packaging proteins? A) Nucleus B) Golgi apparatus C) Mitochondria
B) Golgi apparatus
What is the function of the nucleolus?
The nucleolus is responsible for producing ribosomal RNA (rRNA) and assembling ribosomes.
True or False: All cells have a cell wall.
False
What organelle is responsible for cellular respiration?
mitochondria
Fill in the blank: The __________ transports materials within the cell.
vesicle
What is the function of the cell membrane?
The cell membrane protects the cell and controls the movement of substances in and out.
Multiple Choice: Which of these organelles is only found in plant cells? A) Mitochondria B) Chloroplast C) Ribosome
B) Chloroplast
