Answer:
Starch present in A and C, starch not present in B.
Explanation:
Photosynthesis is the process by which plants synthesise sugar.
This process requires light energy, carbon dioxide, and water, and produces sugar and oxygen. This sugar can be turned into starch.
In leaf B, the chemical that absorbs carbon dioxide would mean that there is none in the air for the plant to take in and use for photosynthesis, so it would not make sugar which can be converted to starch.
This is in contrast to C and A, where there is carbon dioxide present in the bag that can be used in photosynthesis.

The correct answer is B. Protection and dispersal of seeds
Explanation:
In plants, fruits are structures that form as a result of fertilization, which makes ovules become seeds and flowers maturate to become fruits. This is necessary for the reproduction of plants, as fruits contain seeds or genetical material that is protected by different layers and leads to new plants if seeds are dispersed. The process of dispersal commonly occurs as the fruit falls from the plant or is eaten by other organisms and then disperse in other areas, which allow plants to reproduce. According to this, the main function of fruits is protection and dispersal of seeds.
Answer:
Genes are a set of instructions that determine what the organism is like, its appearance, how it survives, and how it behaves in its environment. Genes are made of a substance called deoxyribonucleic acid, or DNA. They give instructions for a living being to make molecules called proteins.
Explanation:
Genes tell your body how to make all its proteins. Each new cell in the growing embryo receives a full set of genes. But not every cell needs to make every protein and cells make some proteins only at certain times. Some genes are instructions for proteins that regulate the activity of other genes.
