⭐ Remember: = plant + eukaryotic + autotroph + starch

onion eukaryotic plant cells that can be stained with methylene blue to make structures such as the nucleus easier to observe.

➡ What is it? → Plant cells
➡ Cell type? → Eukaryotic
➡ Auto or heterotroph? → Autotroph
➡ Important structures? → Cell wall, cell membrane, nucleus, cytoplasm
➡ What do they do? → Wall = support; membrane = controls movement; nucleus = DNA

• Picture clue: Rectangular/brick-like cells

⭐ Remember: plant + eukaryotic + autotroph + cell wall
