Answer:
Plant grow using a process called photosynthesis. This is a process in which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and creates oxygen as a byproduct. The plant uses the energy from the sun in order to create energy for itself while at the same time taking up carbon dioxide and water to grow.
Explanation:
(A) sporophyte, pollen cone, microsporangia, microspores, pollen nuclei
What are the various structures of male pine trees?
Like other living things, trees use a number of reproduction techniques. The pine cone, a unique structure that pine trees have evolved, serves as the primary method of reproduction. The pine cone is essential for effective seed fertilization and aids in the spread of seeds over a large area. Typically, a single pine tree will have both male and female pine cones. Pine trees possess both male and female reproductive structures, or cones. Pine trees produce seeds to reproduce. Cones, the male and female reproductive organs of pine trees, are both present. the pollen-producing male cones.
Therefore sporophyte is the largest structure on male pine tree followed by pollen cone followed by microsporangia, microspores, pollen nuclei.

Answer:
patented products
Explanation:
A patented product is one that has gone through a public concession process that has ruled that a particular company or manufacturer has exclusivity in the manufacture and distribution of that product on the market.
There is a concern about the existence of patented products in relation to genetically modified organisms, because this may prohibit the manufacture of similar products. In the case of agricultural crops, this concern becomes even greater, because the controversy of genetically modified and authenticated crops may end up being invaded and contaminating the plantation that has not been genetically modified, causing the producer to lose production rights for the contaminated crop.
B is the correct answer. Good luck :)
