Organelle for cellular respiration –

Nuclear membrane
Eukaryotic Cells
Plant Cells have, and Animal
Cells don’t
• Chloroplasts –
organelle responsible
for photosynthesis
• Cell Walls – a
structure outside of
the membrane to
provide support
• Very large vacuoles to
store extra water
This is a typical plant cell
• It contains a cell wall,
chloroplasts, a very
large vacuole.
• Why do plants need
large vacuoles?
•ANSWER: This is
where food and water
are stored.
