Accepted Answer

### Question 22:
# Brief Explanations:
Chloroplasts are surrounded by two membranes: an outer membrane and an inner membrane. This is a fundamental structural feature of chloroplasts in plant cells (and some algae) related to their function in photosynthesis.
# Answer:
Two

### Question 23:
# Brief Explanations:
The outer membrane of a chloroplast is smooth. It acts as a protective layer and has a relatively simple, non - folded structure compared to the inner membrane which is highly folded into thylakoids.
# Answer:
Smooth

### Question 24:
# Brief Explanations:
The individual sacs formed by the inner membrane of the chloroplast are called thylakoids. These thylakoids are the sites where the light - dependent reactions of photosynthesis occur.
# Answer:
Thylakoids

### Question 25:
# Brief Explanations:
Thylakoids are arranged in stacks (grana) like pancakes. The grana structure helps to increase the surface area for the photosynthetic reactions to take place.
# Answer:
Stacks (or grana)

### Question 26:
# Brief Explanations:
The pigment found inside a thylakoid is chlorophyll. Chlorophyll appears green because it reflects green light and absorbs other wavelengths of light (mainly red and blue) for photosynthesis.
# Answer:
Chlorophyll; Green

### Question 27:
# Brief Explanations:
Other pigments that trap sunlight are called accessory pigments. These pigments assist chlorophyll in capturing a wider range of light wavelengths for photosynthesis.
# Answer:
Accessory

### Question 28:
# Brief Explanations:
Accessory pigments such as carotenoids (including carotene and xanthophyll) are typically yellow, orange, or red. These colors are due to their ability to absorb light in different regions of the spectrum compared to chlorophyll.
# Answer:
Yellow, orange, red (e.g., carotenoids like carotene - orange, xanthophyll - yellow)

### Question 29:
# Brief Explanations:
Stacks of thylakoids are called grana (plural), and a single stack is called a granum (singular). The grana structure is important for organizing the thylakoids to maximize the efficiency of photosynthesis.
# Answer:
Grana

### Question 30:
# Brief Explanations:
Stacks or grana are connected to each other by stroma lamellae (or intergranal lamellae). These structures help to maintain the overall structure of the chloroplast and ensure that the thylakoid system is interconnected.
# Answer:
Stroma lamellae (or intergranal lamellae)
