Mr 10 Departure Betwixt Principal Lymphoid Organs Together With Secondary Lymphoid Organs

Primary Lymphoid Organs (Example: Thymus, Bone marrow, Bursa of Fabricius)

 1. The lymphoid stalk cells proliferate, differentiate together with mature

2. Contain either B cells or Tcells

3. Antigen cannot enter  in

4.They atrophy alongside age
Secondary Lymphoid Organs ( Example: Spleen, Lymph nodes, Peyers patches, Tonsils)

 1. The lymphoid cells overstep away functional

2. Contain both T together with B cells.

3. Antigen enters inwards together with stimulates the lymphoid cells

4. They increase inwards size alongside age

Mr 10 Divergence Betwixt Angiosperms Together With Pteridophytes

Image
Pteridophytes  p(Gk. Pteron=feather; phyta=plants) are called equally seedless vascular cryptogams equally they correspond the get-go grouping of province plants alongside vasculature, xylem as well as phloem. Plant trunk is sporophytic differentiated into truthful roots, stalk as well as leaves. Pteridophytes are commonly called equally the “botanical snakes” equally they evolved after bryophytes (the amphibians of the found kingdom). Example : Pteris, Adiantum Angiosperms (Gk. Angios=closed; spermae=seeds) Angiosperms are flowering, seed bearing vascular plants that aeroplane the largest as well as the nearly evolved grouping of found kingdom. They are truthful flowering plants where the seeds are completely enclosed within a fruit wall. The ovules are protected within the ovary which after develops into fruit. Example: coconut, mango, rose 1. Angiosperms are adapted to broad diversity of environments (may endure mesophytes, hydrophytes, xerophytes, epiphytes etc)

Mr Ten Divergence Betwixt Epigeal As Well As Hypogeal Seed Germination

Image
The term germination designates the overall processes showtime amongst the imbibition of H2O yesteryear dry out seed together with ending when a component of the embryo penetrates the seed coat. This procedure include prison theatre cellphone division, embryo enlargement together with increase inwards metabolic activities. There are 2 types of germination:   Epigeal together with Hypogeal Epigeal vs Hypogeal Epigeal Germination: (epi (Gk) way above, geal (Gk): earth) Example: Bean, Castor 1. In this type of germination, the seed /cotyledons emerge out of the reason or higher upwards the soil. 2. The cotyledons plow light-green (photosynthetic) together with deed equally firstly leaves of the plant. 3. There is greater elongation of the hypocotyl. 4.The lastly piece of occupation of hypocotyl is curved to protect the plumule from the friction of the soil. 5. Energy for growth primarily derived from cotyledon Hypogeal Germination:  (hypo (Gk) way below, geal (Gk): earth)

Mr 10 Departure Betwixt Fsh Too Lh

FSH (Follicle Stimulating Hormone) or Gametokinetic factor: In males , stimulates spermatogenesis. In females, stimulates increase of ovarian follicles together with secretion of estrogen.  LH (Luteinsing Hormone) or Interstitial Cell Stimulating Hormone: In females, together alongside FSH, it triggers ovulation, stimulates conversion of ovarian follicles into corpus luteum together with secretion of progesterone inwards females.It helps inwards maintaining pregnancy past times controlling estrogen together with progesterone. FSH  vs LH FSH (Follicle Stimulating Hormone) 1. It controls the evolution of primary sexual activity organs. 2. It create gamete formation inwards primary sexual activity organs. 3. It stimulates the secretion of estrogen past times growing graafian follicle. 4. It controls thee commencement one-half of ovarian or menstrual cycle. 5.
