Gcse/Igcse biology 1

Description

Every organism that ever evolved, started from a simple unicellular structure which can be regarded as a living entity

Biology as a field is aimed at studying organisms and lives at different levels. This ranges from the simple unicellular organism such as, amoeba, bacteria to the most advanced organisms such as humans, elephant etc

This course is aimed at making students understand the basic concept of cell, as well as its structures and it functions..

The importance of cell cannot be overemphasized, be it unicellular organism or multicellular organism, every organism is made up of cells. Cell is the basic structural and functional unit of life.

In this course we shall be answering the following questions:

• What are the structural differences between prokaryotic cells and eukaryotic cells?

• Organelles unique to plant cells?

• Why should a plant absorb mineral ions by active transport and not by diffusion?

• Why the need for cell differentiation and cell specialisation?

• What are the advantages of stem cells to humanity?

• What is the advantage of electron microscope over light microscope?

In this course we shall be discussing:

1. Cell structure

2. Cell organelles all subcellular structures

3. Similarities and differences in plant and animal cells to stop

4. We shall be looking at cell division

5. Differences between prokaryotic and eukaryotic cells

6. Cell differentiation as well as specialisation.

7. Introduction into microscopy, as well as different types of microscopes

8. How to calculate magnification of a light microscope

9. Culturing of microorganisms.

10. How to use a light microscope to examine an onion cell and the cheek cell

11. Transport across cell membrane using diffusion, osmosis active transport.

12. Going over some essential experiments

13. You shall be serving past questions on every segments, and lots more
