Cell Structure Flashcards
What is the function of the cell membrane?
The cell membrane protects the cell and controls what enters and exits.
What structure provides support to plant cells?
The cell wall.
What is a capsule in bacterial cells?
The capsule is an outer layer that provides protection.
What is the role of centrioles in a cell?
Centrioles organize the movement of chromosomes during cell division.
What do chloroplasts do?
Chloroplasts convert sunlight into chemical energy through photosynthesis.
What is cytoplasm?
Cytoplasm is everything between the nuclear membrane and the cell membrane.
What is the function of the cytoskeleton?
The cytoskeleton gives the cell its shape and provides structural support.
What is the function of the endoplasmic reticulum?
The endoplasmic reticulum is a passageway where chemicals are made.
What does the flagellum do?
The flagellum is a hair-like structure that helps the cell move.
What is the role of the Golgi apparatus?
The Golgi apparatus packages chemicals for the cell.
What is contained within a lysosome?
Lysosomes contain digestive chemicals that break down waste.
What is the function of mitochondria?
Mitochondria convert nutrients into energy for the cell.
What is a nucleoid?
A nucleoid is a region in bacterial cells that contains genetic material without a nuclear membrane.
What is the purpose of the nuclear membrane?
The nuclear membrane protects the nucleus and regulates what enters and exits.
What is the nucleolus?
The nucleolus is a structure that manufactures ribosomes.
What is the main function of the nucleus?
The nucleus contains DNA and regulates gene expression.
What is an organelle?
Organelles are specialized structures within a cell that perform specific functions.
What is a pilus?
A pilus is a hair-like structure that helps bacteria attach to surfaces and transfer genetic material.
What is a plasmid?
A plasmid is a circular piece of genetic material found in bacterial cells.
What is the role of plastids?
Plastids store food or pigments in plant cells.
What do ribosomes do?
Ribosomes synthesize proteins by translating mRNA into amino acids.
What is a vacuole?
A vacuole is a sac that stores water, nutrients, or waste products.
What is the function of a vesicle?
A vesicle is a small structure that transports materials within the cell.
