Question

mine diagram shows the arrangement of cells inside the leaf of a green pa
contents are shown) which cells normally contain chloroplasts.
a)1 and 2.
b)1 and 4.
c) 2 and 3.
d)2 and 4.​

Answer 1

Answer:

2 and 3

Explanation:

2 represents palisade cells which contain chloroplast.

3 represents spongy cells which also contain chloroplast .

both palisade cells and spongy cells are together known as MESOPHYLL CELLS. This type of differentiation is observed in dicot leafs ,whereas it is absent in monocot leaves.

Answer 2

Answer:

The cells that normally contain chloroplast are palisade cells and guard cells. Hence the correct answer is option d.

Explanation:

1. The given image is the cross section of a leaf. The type of cell marked as number 1 is the upper epidermis. This layer is responisble for the production of cuticles.
2. The cells marked as number 2 is palisade cells. Palisade cells contain a large number of chloroplast, making them the primary site of photosynthesis.
3. The cells marked as number 3 is the mesophyll cells. They also contain chloroplast but not as much as in palisade cells.
4. The cells marked as number 4 is guard cells. They also contain chloroplast for photosynthesis.
