In 1665 Robert Hooke observed a thin slice of cork ( dead cell)under this primitive microscope.
In 1670 A.V. Leeuweehoek observed and describe cell in drop of pond water ( living cell )using compound microscope.
Robert Brown discover Nucleus ( control center of the cell ).
In 1839 cell theory was given by Scheilden and Schwann

School just teaches for marks 😔 that's why I am here😅

👏👏 clapping for those who have exam tomorrow and studying today

A nerve cell has to transmit nerve impulses to organs located in different parts of the body so that's why it is long

[saltysid]

8:35 Nerve cells: they are long because they need to pass the messages to the brain from a long distance.
Rbc's: they have a depression to store oxygen
Muscle cells: cylyndrcal and branched as they keep in the movement if contracting and relaxing
also: 9:06 wbc 's can also change their shape to help in destroying germs in our body

[mealsomemories]

Thank you magnet brain for teaching us in lockdown keep raising
If u agree plz reply

[Creativitywithme]

8:37 nerve cells are very long because it perform many functions in like it help in transmission of signals and electrical impluses 😊

[kajaldhaka]

8:35 nerve cell is long as it receives and transmits messages from brain to different part of the body btw ur teaching skills are amazing 👍😊

[harshita]

Nerve cells are long and have branches because they need more surface area to pass the signals to cell by cell

[hemantyadav]

Outstanding teaching mam I love your teaching style which make our concept easier
Thank you mam 🙂🙂

[jaiashutosh]

Nerve cells are usually very long and branched so that it helps in transmission of signals or electrical impulses over all parts of the body

[sumangahalaut]

Mem i have I one question🙋
1- name the smallest cell in our body.

[krishangopalsharma]

Mam, you are nothing but best science teacher 😊

[zeusgaming]

Ever nice I learn everything clearly about this chapter 👌👍

[saniyashukla]

Mera to dusra book h but some topics are same
Wonderful explanation mam 😀😇😇

[anjneyasachan]

The parts of plant cells are - cell wall, cell membrane, cytoplasm, plastid, vacuole, nucleus.
Animal cell consists of cell membrane, cytoplasm, nucleus and vacuole.


Parts of A nucleus are nuclear membrane, nucleoplasm, nucleolus, chromatin material and nuclear pore👍

[ankitasingh]

8:30 Q.1 Why nerve cell are long?
Because each cell is made by its function nerve cell work is to send message from brain to all parts of body 😜
