They are multicellular. 2. They are autotrophs. 3. Plant cells have cell walls made of cellulose. 4. Plant cells have chloroplasts that perform photosynthesis. 5. They alternate generations. It's not too hard to pick out a plant. The green color and growth in a fixed place is usually a good indicator.
