Question

Chloroplasts are double membrane organelles with a smooth outer membrane and an inner membrane that is folded into disc-shaped sacs called the thiylakoid. Color and label the outer membrane light green Color and label the inner membrane brown Thylakoids contain chlorophyll and other pigments (red, orange, yellow, brown) and are found in stacks called granum (grana, plural.) Color and label the thylakoids dark green , then highlight the entire stack of granum with yellow These stacks are connected to other stacks by channels called lamellae Color and label the lamella orange Grana are surrounded by a gel-like material called stroma. Color and label the stroma blue. 11. How many membranes surround a chloroplast? 12. Thylakoids form stacks called 13. Stacks of granum are connected to each other by

Answer 1

Light green oute membrane. Brown inner membrane, Dark green thylakoids, Yellow granum. Blue stroma and orange stroma lamella.

Chloroplasts are double membrane structures. There is a gel like substance inside called stroma. Stroma has grans which are like columns and made of membranes called thylakoids. Thylakoids have chlorophyll which help in absorbing the light rays.

11. Two membranes surround chloroplasts.

12. Thylakoids form a stack called granum.

13. Stacks of grana are connected to each other by stroma lamella.
