cells and organelles Flashcards
What is the function of the nucleus in a cell?
The nucleus stores the cell’s genetic material and coordinates activities like 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 organelle is responsible for photosynthesis in plant cells?
Chloroplast
Which type of cell lacks a nucleus?
Prokaryotic cell
What is the primary function of the endoplasmic reticulum?
The endoplasmic reticulum is involved in the synthesis of proteins and lipids.
Multiple Choice: Which organelle is known for packaging and distributing proteins? A) Ribosome B) Golgi apparatus C) Lysosome D) Nucleus
B) Golgi apparatus
True or False: Lysosomes are involved in breaking down waste materials and cellular debris.
True
What is the function of the cell membrane?
The cell membrane controls the movement of substances in and out of the cell.
Fill in the blank: The __________ provides structural support and protection for plant cells.
cell wall
Which type of cell contains membrane-bound organelles?
Eukaryotic cell
What is the role of the cytoplasm in a cell?
The cytoplasm is the jelly-like substance that fills the cell and holds organelles in place.
Multiple Choice: Which organelle is involved in detoxifying harmful substances? A) Mitochondria B) Smooth ER C) Golgi apparatus D) Ribosome
B) Smooth ER
True or False: Plant cells have centrioles.
False
What is the function of vacuoles in plant cells?
Vacuoles store nutrients, waste products, and help maintain turgor pressure.
Fill in the blank: The __________ is a network of protein filaments that helps the cell maintain its shape.
cytoskeleton
Which organelle is responsible for the degradation of cellular components?
Lysosome
What is the primary role of chloroplasts?
Chloroplasts convert sunlight into chemical energy through photosynthesis.
Multiple Choice: Which cell type is generally larger? A) Prokaryotic B) Eukaryotic
B) Eukaryotic
True or False: Ribosomes can be found free-floating in the cytoplasm or attached to the rough endoplasmic reticulum.
True
What is the function of the Golgi apparatus?
The Golgi apparatus modifies, sorts, and packages proteins and lipids for secretion or delivery to other organelles.
Fill in the blank: The __________ is selectively permeable and regulates what enters and exits the cell.
cell membrane
What organelle is known as the site of ATP production?
Mitochondria
Which type of cell contains chloroplasts?
Plant cell
