Permanent vacuole - Contains cell sap, a weak solution of sugar and salts.
Chloroplasts - where photosynthesis happens (making food for the plant).They contain a green substance called chlorophyll.
Most cells are specialised for their function
similar cells group to create our organs
how plant leaves adapt to their function:
1.palisade leaf cells are adapted for photosynthesis
-chloroplasts for photosynthesis
-their tall shape means a lost of surface area is exposed down the side…
