<span>An advantage for the angiosperm approach to the formation of nutritive tissue is in energy conservation.</span> <span>The nutritive tissue is formed via double fertilization in Angiosperms. The advantage of double fertilization is that the plant does not invest energy in seed nutritive tissue until after an egg has been fertilized. This means that endosperm (nutritive tissue) starts to develop and store nutrients after it has been fertilized by a sperm cell.</span> Another advantage is that the endosperm nucleus is very active and <span>divides rapidly, so it forms the nutritive tissue very quickly.</span>
Answer:
a. Entropy
Explanation:
Entropy is the measure of the degree of disorder of a system, being a measure of the unavailability of energy. Rudolf Clausius was the first to use the term Entropy in 1865. Entropy would be the measure of the amount of thermal energy that cannot be reversed into mechanical energy (cannot perform work) at a given temperature.
Because of this concept, we can understand that the tendency of energy to be lost as heat during the transformation of organic matter supports the concept of entropy.
Answer:
The correct match is given below:
Explanation:
- The condition of having gametes similar in shape, but different in size – anisogametes.
- The condition of having anisogametes - anisogamy
- The part of the stamen of a flower that bears the pollen – anther
- An organ in simpler plants that produces sperm cells – antheridium
- An organ in lower vascular plants, gymnosperms, mosses, and liverworts which produces an egg cell - archegonium
- A reproductive organ of gymnosperms having a central axis with radiate scales and bracts; can either produce pollen or ovules – cone
- An act of fertilization involving the transfer of cell contents to another cell; usually occurs in simpler organisms – conjugation
- A large gamete with stored food - Egg
- A long, whip-like structure extending from a cell used for locomotion- Flagellum
- An organ of lower plants, some protists and some fungi that produces gametes - gametangium
- Gamete producing organs in animals – gonads
- Cone-bearing plant; often called evergreen – Gymnospers
- Incapable of independent movement - immotile
- Gametes that are the same in size and shape - isogametes
- Capable of independent movement- motile
