Biology- e-learning portal --cells, organelles and organisation of living things

Hi Students,

Here is the second list of sites you can go to to learn science in a fun way.
The site is good for quick revisions and introductions to the topics.

Lesson 18: Specialised cells

Hi,
More colourful slides for your learning experience.
The 12 slides are very useful in learning the following concepts:

• shape and size of specialised cells are related to their adaptation for their functions
• guard cell, unevenly thickened wall, to open and close the stoma
• long finger-like shape to increase surface area to volume ratio in root hair cell
• hollow cell with thick lignified walls in xylem to conduct water upwards
• ciliated lining cell in trachea to waft dust and germs upwards the air passages
• long tail and plenty of mitochondria in sperm cell to swim
• plenty of yolk and large in egg to store nutrients for growth
• ability to move about in tissue fluid and ingest bacteria in phagocyte
• ability to contract and relax thus change length in muscle cell
• biconcave disc shape with haemoglobin in red blood cell to absorb and transport oxygen
  
• long, myelinated axon in nerve cell to transmit nerve impulses over long distances
• cell, tissues, organs, systems, organism-order of complexity

Lesson 16: Cell, tissues, organs, systems and organism

Hi,

This beginning chapter of biology is relevant to all classes.
Enjoy the following 21 slides and revise the following concepts:

• plant and animal cell structure
  
• cell organelles-mitochondria, chloroplasts, nucleus, cell membrane
• specialised cells-red blood cells, nerve cells, sperm cells, muscle cells, root hari cells, xylem cells, pollen cells, guard cells
• cell organised into tissues, organs, systems and organisms
  
• examples of various systems in plants and animals
• short questions

Lesson 8: Animal and plant cells

You may want to view these powerpoint slides before attempting questions on this topic in your assignments. There are 10 slides covering the following concepts:

• plant cell and its organelles
  
• animal cell and its organelles
• cheek cell, onion cell as seen under the microscope
  
• functions of various organelles in plant and animal cells

Lesson 7: Organelles in cells

Hi,

You may want to view these Powerpoint slides before attempting the worksheet on this topic.
the coverage includes the following:

• onion and cheek cells
• cell organelles
  
• cell membrane-covers cell allow materials in or out of cell
  
• cell wall-covers plant cell, for support and strength
  
• cytoplasm-houses all cell organelles
  
• golgi body-processes materials and packages them for transport
  
• mitochondria-site where ATP, energy, is released during cellular respiration
  
• nucleus-contain chromosomes/DNA, controls all cell activities, involved in cell division
  
• endoplasmic reticulum-packages the proteins from ribosomes
  
• chloroplast-make glucose/food using sunlight energy
  
• vacuole-stores water, wastes and nutrients
  
• ribosome-site where protein is made
  
• centrioles- involved in cell division
