Answer 2

Answer:

Option (A) Sunflower is the correct answer.

Explanation:

A Sunflower stem has cells in the endodermis that are rich in starch grains. This layer is also known as the starch sheath. The inner layer of the dicot stem is the central and innermost layer of the cortex.

               The endodermis is a layer of cells that do not have a gap between cells like other layers of the body. This layer helps to form the inside of the gut and other organs. The endodermis helps to control the flow of water, ions, and hormones into and out of the vascular system. It is possible that the organism stores starch grains as a food reserve. The stem of a dicot stem contains the endodermis, a layer of cells that covers the interior of the stem. This layer is called the starch sheath.

• Dicot plants have a tough, outer layer of skin called the epidermis. This layer is covered with a tough cuticle, which protects the plant's inner layer of skin called the dermis.
• There are also plenty of hair-like structures called stem cells in dicot plants, which help the plant grow.
• The example sunflower and Cucurbita are two plants that are commonly used in botany.
• Dicot stems have a ring of vascular bundles around the pith, and the pith is concentrated at the center of the stem.
• Xylem is a type of tissue found in plants that transports water and minerals up and down the plant's stem or root. It is called an "end arch" because it is located at the end of the stem or root where the primary xylem strands meet.

• The xylem grows from the center outward, or from the inside out. The protoxylem is closest to the center of the stem or root, and the metaxylem is closest to the periphery of the stem.
• The stems of dicot plants typically have end arch development and the roots are typically considered to have exarch development.

• The dicot plants have meristematic tissue in their vascular bundles which is responsible for growth. The tissue has a regenerative capacity, which allows it to form new tissue when it is grafted.

• Closed vascular bundles are present in monocots because they lack the cambium. Monocot stems have vascular bundles that are closed, collateral, and end arch.
