How do mitochondria function in the cell?
Click to flip
Mitochondria are the powerhouses of the cell, generating ATP through cellular respiration.
Click to flip
What is the function of the endoplasmic reticulum?
Click to flip
The endoplasmic reticulum (ER) assists in the production and transport of proteins and lipids.
Click to flip
What does the Golgi apparatus do in a cell?
Click to flip
The Golgi apparatus modifies, sorts, and packages proteins for secretion or use within the cell.
Click to flip
What role do lysosomes play in a cell?
Click to flip
Lysosomes break down waste materials and cellular debris within the cell.
Click to flip
What is the function of chloroplasts in plant cells?
Click to flip
Chloroplasts conduct photosynthesis, converting solar energy into chemical energy stored in glucose.
Click to flip
How does the cytoskeleton contribute to cellular function?
Click to flip
The cytoskeleton provides structural support, aids in cell movement, and organizes the cell's contents.
Click to flip
What is a vacuole's function in a cell?
Click to flip
Vacuoles store nutrients, waste products, and help maintain turgor pressure in plant cells.
Click to flip
What distinguishes prokaryotic cells from eukaryotic cells?
Click to flip
Prokaryotic cells lack a nucleus and other membrane-bound organelles, unlike eukaryotic cells.
Click to flip
What role do cilia and flagella play in cells?
Click to flip
Cilia and flagella aid in cell movement and the transport of substances across the cell surface.
Click to flip
How do cells communicate with each other?
Click to flip
Cells communicate via chemical signals called ligands, which bind to receptors on the cell membrane.
Click to flip
What is the role of cell walls in plant cells?
Click to flip
Cell walls provide structure, protection, and support to plant cells and aid in regulating water intake.
Click to flip
What is the purpose of the cytoplasm?
Click to flip
Cytoplasm is the gel-like substance where organelles are suspended, facilitating cellular processes.
