  Prokaryotic cells lack a nucleus and organelles
• Where is genetic material stored in a prokaryotic cell?

  In the nucleoid region
• Name two organelles found in eukaryotic cells but not in prokaryotic cells.

  Mitochondria and endoplasmic reticulum
• Why are prokaryotic cells generally smaller than eukaryotic cells?

  They have simpler structures and fewer organelles

  In the cytoplasm
• Name three structures found in a prokaryotic cell.

  Cell membrane, ribosomes, and cell wall
• What is a plasmid?

  A small DNA molecule that carries genes
• What is the function of a plasmid?

  To provide genetic advantages like antibiotic resistance
• How do prokaryotic cells differ from eukaryotic cells in terms of size?

  Prokaryotic cells are generally smaller
• How do prokaryotic cells differ from eukaryotic cells in terms of complexity?

  Prokaryotic cells are less complex

  1. It is circular and floats in the cytoplasm
• What are three key features of an animal cell?

  Cell membrane, nucleus, mitochondria
• What is the function of the nucleus in an animal cell?

  It stores genetic material
• What does the cell membrane do in an animal cell?

  It controls the movement of substances
• How does the structure of mitochondria relate to its function in animal cells?

  Its folded inner membrane increases energy production

• What is the function of the cytoplasm in an animal cell?

  Transport substances around the cell
• What is the primary function of the cell membrane in an animal cell?

  To protect the cell
• What are three key features of plant cells that differ from animal cells?

  Chloroplasts, cell wall, and vacuole
• What is the role of chloroplasts in a plant cell?

  They absorb light energy for photosynthesis
• How does the cell wall help a plant cell?

  It provides support and shape to the cell
• What is the function of the vacuole in a plant cell?

  It stores water and nutrients for the cell
• What is the purpose of plasmodesmata in plant cells?

  They allow communication between plant cells
