Biology students question and answer

Basics🌹

Cell in biological science was discovered from:
A. Leaf tissue
B. Stem cell pines
C. Shoot apical meristem
D. Cork piece

Smooth endoplasmic reteculum.are those which have no presence of ribosomes
Rough endoplasmic reticulum are those reticulum which have presence of ribosomes

Organelles are the chemical factories in the cell these organelles are mostly present in the cytoplasm of the cell
These organelles do movement with the cytoplasm

1) E.R (endoplasmic reteculum)
These are the tube like structure present in the cytoplasm these tubes lay down from the nuclear membrane to the end of cell membrane
There are two types of (E.R)
1) rough E.R
2) smooth E.R

Tomorrow we shall clerify the both types of E.R and it's function

In text topic I shall tell you about organelles so you should have focus on your study

There are two types of cell
1) prokaryotic cell
2) eukaryotic cell

Prokaryotic cell..
These are the cells which are called not true cells because these have not a complete system of organelles and these types of cell have not present a nuclear membrane
Ex. Bacterial cell

Eukaryotic cell..
These cells are called true cells because these cells have complete system of organelles and nuclear membrane is also present to it's nucleus

Biogenesis
Is term in which living synthesis from living things
Abiogenesis
Is a term in which living things synthesis from non-living things

When the organ combine they make the organ system
When the organ system combine they make the organism

When same type of tissue combine with each other they make the organ
Just like tissue of eye combine with each other they make the eye

What is a tissue.?
Tissue is a combination of two or more than two cells they make the tissue
