Cell Biology Flashcards
The primary difference between prokaryotic and eukaryotic cells is:
The presence of a nucleus
Which organelle is responsible for producing energy in eukaryotic cells?
Mitochondria
The rough endoplasmic reticulum is different from the smooth endoplasmic reticulum because it:
Is involved in protein synthesis
The Golgi apparatus is primarily responsible for:
Packaging and modifying proteins
Which organelle is found only in plant cells?
Chloroplasts
According to cell theory, all cells arise from:
Pre-existing cells
The nucleus is the control center of the cell and contains:
DNA
Mitochondria are often referred to as the “powerhouse of the cell” because they:
Store energy
Ribosomes are responsible for:
Protein synthesis
Lysosomes are organelles that:
Break down cellular waste
The cell membrane is primarily composed of:
Lipids
The cytoskeleton is a network of protein filaments that:
Provides structural support
The endoplasmic reticulum is involved in:
Both protein and lipid synthesis
The cell membrane is selectively permeable, meaning that:
It only allows certain substances to pass through
The endoplasmic reticulum can be either rough or smooth, depending on the presence of:
Ribosomes
The Golgi apparatus modifies and packages proteins for:
Both export and storage
Mitochondria use a process called ** to produce energy in the form of ATP.
Both export and storage
Chloroplasts use a process called ** to convert sunlight into energy.
Photosynthesis
The nucleus contains the cell’s genetic material, which is stored in:
Chromosomes
The cytoskeleton is involved in:
Cell shape and movement
The cell membrane is primarily composed of:
Phospholipids
