Chloroplast
- The photosynthetic organelles that convert sunlight to stored energy in sugars.
- Chloroplasts have a double-membrane.
- Stroma (a fluid) fills the space within the inner membrane
- Free ribosomes as well as chloroplast DNA reside within the stroma.
- Disc-like thylakoids reside in the stroma.
- Play a role in photosynthesis.

Plant vs. Animal Cell
SHARED FEATURES
- Plasma membrane
- Cytosol
- Nuclear envelope
- Nuclear pores
- Nucleus
- Chromatin
- Nucleolus
- Ribosomes
- Endoplasmic reticulum (both smooth ER and rough ER) and ER lumen
- Golgi apparatus
- Endosome
- Mitochondria
- Peroxisome
- Cytoskeleton made up of: Microfilaments, intermediate filaments, and microtubules
- Centrosome
- Lysosome
- Centriole
- Flagella (though not all animal cells have them and some plant sperm have them)
- Cell wall (made of cellulose)
- Plasmodesmata (channels through the cell wall and plasma membrane connecting the cytoplasms of adjacent cells)
- Central vacuole (storage, waste breakdown, aids metabolism)
- Tonoplast (membrane enclosing central vacuole)
- Chloroplast (photosynthetic organelle) – Outer membrane, inner membrane, stroma (fluid within inner membrane), thylakoids
