Biology-One Liners

 

1-Structural element of cell wall is Microfibrils

---

 

2-Besides cellulose microfibrils, the other two cell wall networks are Pectic and glycoprotein

---

 

3-Pits are depressions in secondary walls.

---

 

4-Ripe fruits soften due to partial solubilisation of pectic compounds

---

 

5-Plasmodesmata were discovered and named by Strasburger

 

 

 

 

 

---

 

6- Secondary wall component of the cell wall is normally in contact with the plasmalemma

---

 

7-The structural material of fungal cell wall is Chitin

---

 

8-Primary wall grows by Intussusception

---

 

9-Hardness of woody tissue is due to Lignin

---

 

10-Glycocalyx is Oligosaccharide part of glycolipids and glycoproteins

---

 

11-The first wall layer of cell is Primary Wall

---

 

12-Middle lamella occurs outer to primary wall

---

 

13-Part of endoplasmic reticulum present in a plasmodesma is called Desmotubule

---

 

14-Plant cells are distinguishable from animal cells in containing Cell wall

 

 

 

 

 

 

 

 

 

 

---

 

15-E.R. was discovered from Liver cells

---

 

16- Endoplasmic matrix part of protoplast shows streaming or cyclosis

---

 

17-Cyclosis is caused by activity of Microfilaments

---

 

18-A ribosome is composed of two subunits

---

 

19-Lysosomes originate from Golgi apparatus

---

 

20-Golgi apparatus cell organelle is involved in formation of saliva, tears, and sweat.
