Question

The given figure shows T.S. of Helianthus leaf with various parts labelled as A, B, C, D, E and F. Identify the parts and select the correct option.

• A. A - Epidermis, B - Spongy parenchyma, C - Palisade parenchyma, D- Stomata, E - Phloem, F - Xylem
• B. A - Epidermis, B - Palisade parenchyma, C - Spongy parenchyma, D- Stomata, E - Xylem, E - Phloem
• C. A - Epidermis, B - Palisade parenchyma, C - Spongy parenchyma, D- Stomata, E - Endodermis, F - Xylem
• D. A - Epidermis, B - Palisade parenchyma, C - Spongy parenchyma, D- Stomata, E - Phloem, F - Xylem

Answer 1

The correct option is D A - Epidermis, B - Palisade parenchyma, C - Spongy parenchyma, D- Stomata, E - Phloem, F - Xylem

1. Epidermis is the outer covering of leaves and is made up of single layer of cells.
2. Palisade parenchyma are vertically elongated plant cells present just below the epidermis.
3. Spongy parenchyma can be defined as loosely arranged irregular leaf tissues that contain chloroplasts. It has many intercellular spaces to facilitate the exchange of gases by stomata.
4. Xylem and phloem are the vascular tissues of a plant that conducts water and minerals to the leaves.
5. So, the correct option is D.
