This type of cell needs a cell wall and chloroplasts

• Plant cell
• Animal Cell
• Bacteria

This organelle is in both plants and animals. It is a barrier between the cell and the environment.  It controls what goes in and out of a cell.

• cell wall
• cell membrane
• cell organelles
• mitochondria

This cell part is in ALL cells. It is the gel-like substance that provides cell shape.

• Chloroplasts
• Chromosomes
• Cytoplasm
• Mitochondria

This organelle is in all eukaryotic cells. It is the control center of the cell because it holds the DNA.

• Mitochondria
• Nucleus
• Chloroplasts
• Ribosomes

Plants perform photosynthesis through this organelle.  It captures energy from the sun and uses it to produce food for the cell.

• Chlorophyll
• Chloroplasts
• Mitochondria
• Golgi Apparatus

This structure is only in plant cells. It is outside of the cell membrane and adds more support/structure to the plant.

• Cell membrane
• Cell Nucleus
• Cell Wall
• Endoplasmic Reticulum
