One of the most impressive structures to be studied.

Given by Singer & Nicholson, a membrane is double lipid layer where lipids are present almost running parallel in the cell circumference.

In between the lipid layers, lie small proteins, membrane-spanning proteins as well as flip flop proteins ( receptors) too..!!

The small ones help in maintaining the quasi-fluid state of the membrane while the membrane-spanning proteins and the receptor proteins are involved in the transfer of chemicals, hormones as well as cell signalling and Cascade mechanisms.

Semi-permeable in nature, cell membrane acts as a scanner to scrutiny the substances interacting with the cell and helps in determining the type and structure of substances to be allowed for entry.

A cell membrane also offers the formation of plasmodesmata in lower forms and as a protective layer in advanced eukaryotic cells.

Hence, a cell membrane can be termed as a sea of lipids where protein components act as floating icebergs.

The wear n tear of the membrane is repaired with the help of Smooth endoplasmic reticulum as well as Golgi Apparatus by a process known as MEMBRANE BIOGENESIS.

The membrane remains continuously in the motion state, can be considered more so as flowing jelly.

In Gymnosperms seed are not covered as an ovary does not enclose the ovule.

Ovarian wall =friut wall (after fertilisation)

Ovule has nucelus(2n) nutririvn tissue and one integument.

One cell of nucleus get modified, and form Megaspore mother cell (2n) which by meiosis form 4 megaspore(n), 4 out of 3 disintegrate and one remain functional.

Functional Megaspore germinates inside ovule and forms female gametophyte(n).

Female gametophyte has Archegonia with egg. After pollination (anemophily;wind) fertilisation takes place. The egg develops into zygot-embryo-seed (2n).

The persistent female gametophyte (n) is now called endosperm. Therefore it is haploid(n).

Gymno seed = three generations ( persistent nucleus is parent sporophyte, the endosperm is persistent gametophyte and embryo is future sporophyte).
