Cell Flashcards
What is the basic structural and functional unit of all living organisms?
Cell
What is the term for a group of similar cells that work together to perform a specific function?
Tissue
Which organelle is known as the ‘powerhouse’ of the cell?
Mitochondria
True or False: The cell membrane is selectively permeable, allowing only certain substances to pass through.
True
What is the process by which cells replicate and divide to produce new cells?
Cell division
Which organelle is responsible for protein synthesis in the cell?
Ribosome
Fill in the blank: The __________ is the control center of the cell and contains the genetic material.
Nucleus
What is the term for the movement of molecules from an area of high concentration to an area of low concentration?
Diffusion
Which type of cells lack a defined nucleus and other membrane-bound organelles?
Prokaryotic cells
What is the term for the process by which cells engulf and digest particles or other cells?
Phagocytosis
True or False: The endoplasmic reticulum is responsible for lipid synthesis and detoxification in the cell.
True
Which organelle is responsible for packaging and distributing proteins within the cell?
Golgi apparatus
Fill in the blank: The __________ is a network of membrane-enclosed tubules and sacs that transports materials within the cell.
Endoplasmic reticulum
What is the term for the process by which cells take in molecules by engulfing them in a vesicle?
Endocytosis
Which organelle contains enzymes that break down waste materials in the cell?
Lysosome
True or False: The cytoskeleton is a network of protein filaments that provides structural support and helps with cell movement.
True
What is the term for the movement of water across a semipermeable membrane from an area of low solute concentration to an area of high solute concentration?
Osmosis
Which type of cells have a defined nucleus and membrane-bound organelles?
Eukaryotic cells
Fill in the blank: The __________ serves as a storage organelle in the cell and can contain nutrients, ions, and waste.
Vacuole
What is the term for the process by which cells release substances outside of the cell?
Exocytosis
True or False: The cell wall is a feature found in animal cells but not in plant cells.
False
Which organelle is responsible for photosynthesis in plant cells?
Chloroplast
Fill in the blank: The __________ are hair-like structures on the cell surface that help with movement and sensing the environment.
Cilia
What is the term for the process by which cells convert glucose into usable energy in the form of ATP?
Cellular respiration
