In flowering plants what structure containing DNA is transported from one plant to another

Biology
1 answer:
azamat3 years ago
8 0

Answer:

Pollen

Explanation:

Flowering plants are plants classified as Angiosperms. They are the most diverse group of plants in the Kingdom Plantae. Angiosperms or flowering plants as their name implies are characterized by the possession of reproductive structures called FLOWER. The male reproductive flower called STAMEN produces their gamete in a structure called POLLEN while the female reproductive flower called PISTIL contains an ovary that produces egg cells called OVULES.

In flowering plants, the pollen of a male flower is transported to the receptive part of the female flower called STIGMA in a process called POLLINATION. The pollen contains the gamete (sperm cell) that conveys the genetic material (DNA) of the male plant. A fertilized ovule develops into a seed, hence, the reason flowering plants are called SEED-BEARING.

Therefore, pollen is the structure containing the genetic material (DNA) that is transported from one plant to another (same species) in flowering plants.

Hemoglobin is the oxygen carrying compound found in human blood. It is found to contain 0.3335% iron by mass. It is already know
Alexus [3.1K]

Answer:

66986.51 g/mol

Explanation:

According to this question, Hemoglobin- an oxygen carrying compound in the blood, is found to contain 0.3335% iron (Fe) by mass.

* One molecule of hemoglobin contains four atoms of iron

If 1 atom of Fe = 55.85g/mol

Then 4 atoms = 4 × 55.85 = 223.4g/mol

So there are 223.4g/mol of Fe in one molecule of hemoglobin

If hemoglobin contains 0.3335% iron by mass, this mathematically means that:

223.4g/mol of Fe ÷ molar mass of hemoglobin = 0.3335%

That is;

223.4/M.M = 0.3335/100

Cross multiply

0.3335 M.M = 22340

M.M = 22340 ÷ 0.3335

M.M = 66986.51

Hence, the molar mass of hemoglobin is 66986.51g/mol.
