Root tip squash almost for sure
Totipotency
Actually describing ntimicrobial properties of plants.
tensile strength

There was so much practical and HSW emphasis in January that maybe a practical wont even come up



Hey... TISSUE culture hasn't even come up FOR ONCE in the past papers...!... WOW :eek:

But to be honest I have one and its not even that good. I would recommend making your own printed notes if you have not done so already or readi material from class or summarising textbook notes. Read the spec as well and check you know all of the points.


are types of natural selection included in the spec?

Read the points on there, on either concept or snab, and imagine an exam question based on it. Check you know exactly how to answer it, answer it, and if you can't, research the topic and read past mark schemes on what the examiners want you to include.

Good luck, this method really helps me to revise.

What content are you stuck on?

Only the process of natural selection is on the spec.

Meiosis is sexual reproduction and mitosis is asexual, mitosis makes 2 identical daughter cells and meiosis makes 4 non-identical daughter cells

Xylem is for structural support and transport of H20 whilst sclerenchyma is only for support
also xylem is found in the inner stem but sclerenchyma is found more in the outer part of the stem.

Do you need it to be more detailed?

Yh i hate microbial proerties one Hope it does't come up this time coz it came up in Jan 13 for describing the stuff in strucured questions.
Are the practicals that are likely to be on the paper only from Unit 2? Or do they put some Unit 1 practicals in it as well?

thanks
