Thylakoids form stacks called grana , and these grana are connected to each other by stroma lamellae (also called stroma thylakoids or intergranal lamellae).

Direct answer

• The disc-like thylakoids in chloroplasts pile up to form stacks known as grana (singular: granum).

• Different grana stacks are linked together by flat, unstacked membrane regions called stroma lamellae (or stroma thylakoids), which act like membrane “bridges” between stacks.
