Answer: option "A" One seed develops from each ovule.
Explanation:
Ovules are the female reproductive part of the plant which is internally covered by the nucellus and integuments further helped in fertilization and development of seed.
After fertilization, ovule is the part of the plant develops into seed, after a period of time food tissue is developed inside it consisting the seed coats called integuments.
pollen grains or sperms are being transferred through the pollen tube to the embryo sacs from integuments only, which results into the fertilization and development of seed.
The outer ring is is the ever first ring but the inner ones tell if it’s old or not.
Abiotic: which are the non-living factors and chemicals in environments which can affect the ecosystem.
The answer is most likely "vascular system". Xylem tissue is a part of a plant's vascular system. Which is mostly responsiple for transportation (of water, food etc.) in a plant. The vascular system of plants is made of two tissues. One is Xylem and the other is Phloem. Phloem transports food from leaves to all other parts of the plant. And Xylem transports water and minerals (which are dissolved in the water) to the leaves.
So if you remove the <u>Xylem</u> tissue from a plant, its vascular system will be affected.
