Answer: Angiosperms represent approximately 80 percent of all known living green plants. Examples range from the common dandelion to ancient flowers such as magnolias. Angiosperms also make up the vast majority of all plant foods we eat. (Ex. grains, vegetables, and fruits.) The angiosperms are vascular seed plants in which the ovule (egg) is fertilized and develops into a seed in an enclosed hollow ovary The ovary itself is usually enclosed in a flower, that part of the angiospermous plant that contains the male or female reproductive organs or both. fruits are derived from the maturing floral organs of the angiospermous plant and are therefore characteristic of angiosperms.

Electron Transport System and Oxidative Phosphorylation: ATP is generated when electrons are transferred from the energy-rich molecules like NADH and FADH 2, produced in glycolysis, citric acid cycle and fatty acid oxidation to molecular O 2 by a series of electron carriers. O 2 is reduced to H 2 O
Answer:
Fertilization
Explanation:
Egg and sperm are cells known as gametes produced by the GAMETOPHYTE of a sexually-reproducing organism via meiosis. Since egg and sperm cells are produced through meiotic division, their chromosomal number is reduced by half of the parental organism. Hence, sperms and eggs are haploid cells (n) produced by a diploid organism (2n).
Sperm is the male gamete while egg is the female gamete. These two haploid gametes fuse in a process called FERTILIZATION, to produce a diploid ZYGOTE that eventually grows into the diploid structure of the organism called SPOROPHYTE. This system of reproduction called ALTERNATION OF GENERATIONS is used by lower and higher plants.
The statement is - True.
The five main factors that determine the weather at a certain place are the:
- geographic location/latitude
It determines the amount of sunlight, as well as the concentration of sun rays, which directly influences the temperature.
- altitude/height above sea level
The lower the place the warmer it is, the higher the place the colder it is, it is a simple rule that applies for all places on the planet, compared with places in their surroundings.
- ocean currents/large lakes
The ocean currents can bring cold and dry or warm and wet air masses, depending on what kind of an ocean current it is. The water also contributes to a more stable weather, with more moderate temperatures because of the thermal properties of the water to cool of and warm up slower than the land.
- winds
The air masses can bring cold and dry or warm and wet weather, so they influence the temperature and precipitation of a place.
- topography
Determines how much a place is exposed to the sunlight and the movement of the air masses.
