EVEREST: 1. INTRODUCTION TO BIOLOGY, biology, CELL, cell division - Coggle…
-
biology
-
various studies
- study of living organism(plants, animals, micro organisms) is called biology
-
- study of (only) animals is zoology
-
- study of (only) plants is botony
-
-
-
some more basics:
-
means based on the characterstics of a organism classyfing, naming and describing a organism
-
-
CELL
- robert hooke is the one who gave the name cell
-
-
-
-
-
-
says new cells arises from pre- exixting cells (means new cells are inherited by already exixting cells and due to this nature) cells are known as hereditary unit of life
it is a study of cells regarding their structure, functioning and their organelles(underlying specialized structure)
- microscope is one the most pecious invention that helped alot in cytology(in studying cells)
types of microscopes
-
- phase contrast microscope
-
-
- light(optical microscope)
-
- living cells was first observed by antony van leeuwenhoek
cell division
in mitosis one parent cell is divided into 2 daughter cells and both daughter cells have equal no of chromosomes to parent cell(diploid)
-
-
cancer/ tumor is said to be result of uncontrolled mitosis because here cells are continuously increasing and developing and spreading all over without limit
-
-
- here new cell are formed by exixting cells / cells will be incresing in number
