Reproduction of new cells are the function of the cell cycle is especially important to burn victims. Hence option d is correct.
What is reproduction?Reproduction is defined as birthing is the process by which a living thing produces offspring. To reproduce is to reproduce. It is a biological procedure by which an organism creates a physiologically identical progeny. Generation after generation, reproduction makes possible and ensures the survival of species.
The phases of the cell cycle are G1, S, G2, and mitosis. In gap 1, the cell expands in size and copies the DNA during the synthesis phase. The cell goes through preliminary modifications in the gap 2 phase. The real division takes place during the mitotic phase, when the cell multiplies and grows in quantity to replace the burned victim's old and dead cells. It encourages the wounded area's growth and healing.

Answer: (J) The chlorophyll necessary for photosynthesis is present but hidden by red pigment.
Explanation: Every plant has chlorophyll to help with the production of food through photosynthesis.
For plants with red leaves or any other color but green, the pigment simply acts as a 'sunscreen to the plant', who perhaps doesn't require so much sunlight in its photosynthesis.

What role does the sclerenchyma play?Sclerenchyma's primary job is to offer mechanical support. They are made up of lengthy, slender cells that have a thick lignified wall. They lack protoplast and are largely dead.
The complete chart and table are given in the image attached.
A basic permanent tissue known as parenchyma makes up a large portion of the ground tissues of plants, where vascular tissues and other tissues are attached. They are non-vascular and made up of undifferentiated, primitive living cells that have undergone modifications to carry out distinct tasks.
Xylem, along with phloem and cambium, is a key component of vascular tissue. Its primary functions include providing mechanical support and storage as well as moving water and solutes from the plant-soil interface to the stems and leaves.
Parenchyma cells, are also a component of phloem and are essential for the storage of water, non-structural carbohydrates, and storage proteins.
