Cell structure and diversity

Take some time to click through this site to learn more about cells and their structures.   Here is another good place to learn about cells.   Look through each site and then leave me a comment as to which of them you preferred and WHY

If you find any other sites on this topic that you think would help your classmates learn, please include them in the comments too.

Here is a link to a quiz that you can use to check your understanding of cells.  It is brief – my advice is that you study the structure of prokaryotic and eukaryotic cells, and their functions, and their differences, then see how you go on the quiz.  The answers are on there too, so you can self-assess.

Quiz – cell parts and their functions

What do all cells have in common?

Why do cells differentiate?  Within the same organism, there are differences between cells – why is this?

Here’s what you need to do:-

  1. In your groups, make a list of all the different types of cells you can think of (eg, red blood cell, leaf cell)
  2. Each student chooses ONE cell type to research.  Draw the basic structure, state its function, describe why it is unique, and where it is found.
  3. Share your findings with your group.
  4. Discuss the similarities and differences between the cells you described.  Are cells more alike or more different from one another?  Are some cells more complex than others?  Which ones? 
  5. Try to explain why cells have these similarities and differences.

As we embark on topic 9, here is the syllabus outline: Topic 9 – Syllabus outline

This topic can be broken into 3 sections:  structure and growth, transport, reproduction.  This document has notes on all of this. Plant Science Topic notes

We’ll start with plant structure and growth.  Plant structure & growth  Here is Mr Taylor’s presentation on this section.

Some things we’ll discover in this section:

  • why do plants grow towards light?
  • how can you tell if a plant is a monocotyledon or dicotyledon?
  • how can plants modify their roots, stems and leaves for different functions?
