🌳Revision Notes on Reproduction in Organisms🐾 Fertilization: (a) The process of fusion of male and female gamete is called fertilization or syngamy. (b) The female gamete undergoes development to form new organism without fertilization. This phenomenon is called parthenogenesis. It is a modification of sexual reproduction. (c) Gametic fusion taking place outside the body i.e. water is called external fertilization. (d) There must be synchrony of gamete release. Large number of gametes is released to enhance the chance of fertilization. (e) A major disadvantage is that the offsprings are extremely vulnerable to predators. (f) Fertilization takes place inside the body is called internal fertilization. Zygote: (a) Formation of zygote after fertilization is found in all sexually reproducing organisms. (b) In case of external fertilization, zygote is formed usually in water. (c) In case of internal fertilization, zygote is formed inside the body of the organism. (d) Zygote of fungi and algae develops a thick wall that is resistant to desiccation and damage. (e) Organism with haplontic life cycle, zygote undergoes meiosis to produce haploid spores. Embryogenesis: (a) The process of development of zygote into an embryo is called embryogenesis. (b) Zygote undergoes cell division (mitosis) and cell differentiation. (c) Oviparous are the animals which lay eggs and development takes place inside egg. (d) Viviparous animals give birth to the young ones. The development takes place inside the body of the female. (e) In plants: (i) Zygote developed into embryo. (ii) Ovule developed into seed (iii) Integument of the ovule developed into seed coat. (iv) Ovary developed into fruit. (v) Ovary wall developed into pericarp. ᴶᴼᴵᴺ ᴬᴺᴰ ˢᴴᴬᴿᴱ ᵂᴵᵀᴴ ʸᴼᵁᴿ ᶠᴿᴵᴱᴺᴰˢ ➭ @NEET_JEE_CET_QUIZ ✪ ➭ @NEET_JEE_CET_BOT ✪ ╍╍╍╍╍╍╍╍╍╍╍╍╍╍╍╍╍╍╍

♻️ Cell Wall Structure and Function ♻️ ♦️What is Cell Wall? ➖ Cell wall is rigid and protective layer around the plasma membrane ➖ Discovered by Robert hooke in 1665 ➖ Cell wall non-living rigid structure ➖ Found in plants, fungi, prokaryotes and protists ➖ Composition of cell wall varies in different groups ♦️Characteristics of Cell Wall ➖ Cell wall is a rigid and protective layer around the plasma membrane ➖ It is a non-living structure ➖ Animal cells do not have a cell wall ➖ Found in in most plant cells, fungi, bacteria, algae, and some archaea ➖ Cell wall has many important functions in a cell including protection, structure, and support ♦️Cell Wall Structure ✍️Structure of Prokaryotes Cell Wall ➖ Cell wall is made up of peptidoglycon ➖ Peptidoglycan made up of polysaccharide chains cross-linked by unusual peptides containing D-amino acids ➖ A notable difference between the cell walls of gram-positive and gram-negative bacteria is the substantially thicker peptidoglycan layer in gram-positive bacteria. ➖ Cell wall of gram-positive bacteria contains teichoic acids ✍️Structure of Fungi Cell Wall ➖ Fungal cell wall is made up of three main components ✍️Chitin ➖ Polymers consisting mainly of unbranched chains of β-(1,4)-linked-N-Acetylglucosamine in the Ascomycota and ➖ Basidiomycota, or poly-β-(1,4)-linked-N-Acetylglucosamine (chitosan) in the Zygomycota ➖ Both chitin and chitosan are synthesized and extruded at the plasma membrane ✍️Glucans ➖ Glucose polymers that function to cross-link chitin or chitosan polymers ➖ β-glucans are glucose molecules linked via β-(1,3)- or β-(1,6)- bonds and provide rigidity to the cell wall while α-➖ ➖ glucans are defined by α-(1,3)- and/or α-(1,4) bonds and function as part of the matrix ✍️Proteins ➖ Enzymes necessary for cell wall synthesis and lysis in addition to structural proteins are all present in the cell wall. ➖ Most of the structural proteins found in the cell wall are glycosylated and contain mannose, thus these proteins are called mannoproteins or mannans. 🌀Structure of Plant cell wall ➖ Cell wall is made up of 4 layers ➖ Middle lamella, primary, secondary and tertiary wall I) Middle lamella ➖ Cementing layer between the cells ➖ It is made up of ca & mg pectates II) Primary cell wall ➖ Found in growing cell ➖ It has high hemicelluloses & less cellulose content III) Secondary cell wall ➖ Found in mature cell ➖ It has high cellulose & less hemicelluloses content IV) Tertiary cell wall ➖ Laid down on secondary wall ➖ Found in tracheids of gymnosperms ♦️What is Pits? ➖ Cell wall is not uniform in thickness throughout ➖ Certain places cell wall are not laid down, such places are called pits ♨️Pits are of two types I) Simple Pit ➖ Pit chamber is uniform in diameter ➖ Found in angiosperms II) Bordered pit ➖ Pit chamber is flask shaped ➖ Found in gymnosperms ➖ Number of plasmodesmata or cytoplasmic strands are present in pit ♦️ Functions of cell wall ➖ Maintains shape of the cells ➖ Protects cell from mechanical injury ➖ Allows materials to pass in and out of the cell ➖ Prevents undue expansion of cell when water enters by osmosis ᴶᴼᴵᴺ ᴬᴺᴰ ˢᴴᴬᴿᴱ ᵂᴵᵀᴴ ʸᴼᵁᴿ ᶠᴿᴵᴱᴺᴰˢ ➭ @NEET_JEE_CET_QUIZ ✪ ➭ @NEET_JEE_CET_BOT ✪ ╍╍╍╍╍╍╍╍╍╍╍╍╍╍╍╍╍╍╍

✅S-Block Elements: Physical Properties of Alkali Metals: ➖These are soft in nature and can be cut with the help of knife except the lithium. ➖The atoms of alkali metals have the largest size in their respective periods. ➖The first ionization energy of the alkali metals are the lowest as compared to the elements in the other group. ➖The alkali metals show +1 oxidation state. ➖The alkali metals have low values of reduction potential (as shown in table-I) and therefore have a strong tendency to lose electrons and act as good reducing agents. ➖The melting and boiling points of alkali metals are very low because the intermetallic bonds in them are quite weak. Hydroxides of Alkali Metals: a)All the alkali metals, their oxides, peroxides and superoxides readily dissolve in water to produce corresponding hydroxides which are strong alkalies. ➖2Na + 2H2O → 2NaOH + H2 ➖Na2O + 2H2O 2NaOH ➖Na2O2 + 2H2O → 2NaOH + H2O2 ➖2KO2 + 2H2O → 2KOH + H2O2 + O2 b) The basic strength of these hydroxides increases as we move down the group Li to Cs. c) All these hydroxides are highly soluble in water and thermally stable except lithium hydroxide. d) Alkali metals hydroxides being strongly basic react with all acids forming salts. ➖NaOH + HCI → NacI + H2O ➖2NaOH + H2 SO4 → Na2SO4 + 2H2O Halides of Alkali metals: ➖M2O + 2HX → 2MX + H2O ➖MOH + HX → MX + H2O ➖M2CO3 + 2HX → 2MX + CO2 + H2O (M = Li, Na, K, Rb or Cs) (X = F, Cl, Br or I) ➖ll the alkali metals form ionic (electrovalent) compounds. ➖The alkali metals are good conductors of heat and electricity. ➖Alkali metals (except Li) exhibit photoelectric effect ➖The alkali metals and their salts impart a characteristic colour to flame. ᴶᴼᴵᴺ ᴬᴺᴰ ˢᴴᴬᴿᴱ ᵂᴵᵀᴴ ʸᴼᵁᴿ ᶠᴿᴵᴱᴺᴰˢ ➭ @NEET_JEE_CET_QUIZ ✪ ➭ @NEET_JEE_CET_BOT ✪ ╍╍╍╍╍╍╍╍╍╍╍╍╍╍╍╍╍╍╍

✅ What is Pacemaker? A pacemaker is a small device that's placed under the skin in your chest to help control your heartbeat. It's used to help your heart beat more regularly if you have an irregular heartbeat (arrhythmia), particularly a slow one. Implanting a pacemaker in your chest requires a surgical procedure. ✅ Types of pacemakers- Depending on your condition, you might have one of the following types of pacemakers. ✅ Single chamber pacemaker.- This type usually carries electrical impulses to the right ventricle of your heart. ✅ Dual chamber pacemaker- This type carries electrical impulses to the right ventricle and the right atrium of your heart to help control the timing of contractions between the two chambers. ✅ Biventricular - Biventricular pacing, also called cardiac resynchronization therapy, is for people with heart failure with abnormal electrical systems. This type of pacemaker stimulates the lower chambers of the heart (the right and left ventricles) to make the heart beat more efficiently. #Read_IT ᴶᴼᴵᴺ ᴬᴺᴰ ˢᴴᴬᴿᴱ ᵂᴵᵀᴴ ʸᴼᵁᴿ ᶠᴿᴵᴱᴺᴰˢ ➭ @NEET_JEE_CET_QUIZ ✪ ➭ @NEET_JEE_CET_BOT ✪ ╍╍╍╍╍╍╍╍╍╍╍╍╍╍╍╍╍╍╍
