Biochemical Cycle And Life Cycle: 

Biochemical Cycle And Life Cycle

PowerPoint Presentation: 

The term chemical refers here to an element such as Carbon (C) or Phosphate (P) or to a compound, such as water (H2O).

PowerPoint Presentation: 

A BOPGEOCHEMICAL CYCLE is the complete path a chemical takes through the four major components or reservoirs of Earth’s system: • ATMOSPHERE • HYDROSPHERE • LITHOSPEHERE • BIOSPHERE • CRYOSPHERE

ATMOSPHERE(AIR): 

ATMOSPHERE(AIR) -A gaseous mass that surrounds a celestial body, as the earth.

LITHOSPEHRE(LAND): 

LITHOSPEHRE(LAND) -it is the solid part or the outer part of the earth, consisting of crust and upper. It is about 55 km (34 mi) thick beneath the oceans and up to about 200 km (124 mi) thick beneath the continents.

LITHOSPEHERE: 

LITHOSPEHERE

HYDROSPHERE (water): 

HYDROSPHERE (water) -The water on or surrounding the surface of the globe, including the water or oceans and the water in the atmosphere.

BIOSPEHRE: 

BIOSPEHRE The part of the earth and in which living organisms exist or that is capable of supporting life.

Cryosphere: 

Cryosphere Is the frozen part of the Earth which is surrounded by ice, including glaciers, polar ice craps see ice. Etch.

BIOCHEMICAL CYCLE: 

BIOCHEMICAL CYCLE - Is a chemical because it’s chemical that are cycled. BIO means the cycle involves life and GEO means a cycle may include atmosphere, water, rocks, and soils. Example: Carbon Atom

CARBON ATOM: 

CARBON ATOM -Means an atom of a CARBON

PowerPoint Presentation: 

Carbon atom is released into the atmosphere and then taken up by a plant and incorporated into a seed. The seed is eaten by a mouse. The mouse is eaten by a coyote, and the carbon atom is expelled following digestion as scat onto the soil. Decomposition of the scat allows our carbon atom to enter the atmosphere again. It may also enter another organism such as a resource.

Life Cycle: 

Life Cycle - Is the course of developmental changes in an organism from fertilized zygote to maturity when another zygote can be produced. -is a period involving all different generations of a species succeeding each other through means of reproduction , whether through asexual reproduction or sexual reproduction .(a period from one generation of organisms to the same identical)

PowerPoint Presentation: 

Asexual Reproduction -Is a mode of reproduction by which offspring arise from a single parent and inherit the genes of that parent only.

Sexual Reproduction: 

Sexual Reproduction A mode of reproduction involving the fusion of female gamete (ovum) and male gamete (spermatozoon), which forms a zygote that potentially develops into genetically distinct offspring.

Three types of life cycles:: 

Three types of life cycles: • Haplontic life cycle • Diplontic life cycle • Diplobiontic life cycle

PowerPoint Presentation: 

is type of reproductive cycle seen in most fungi, green algae and many protozoa. In this type of life cycle haploid phase of the cells is predominant. The zygote undergoes meiosis and produces haploid spores. These haplonts will then divide mitotic ally to produce more haplonts . These haplonts will give rise to male and female gametes. In haplontic life cycle 2n state of nuclei is present only in the zygote e and this state is very short lived.

ZYGOTE: 

ZYGOTE After a female egg is fertilized, the resulting one-celled organism becomes known as a zygote. Once the egg is fertilized, the zygote begins a two-week period of rapid cell division and will eventually become an embryo. The zygote divides through a process known as mitosis, in which each cell doubles by dividing into two cells. This two-week stage is known as the germinal period of development and covers the time of conception to the implantation of the embryo in the uterus.
