which two groups can plants be divided into ?

flowering
and non flowering

what are characteristics of flowering plants ?

have flowers for pollination
and fruits that surround seeds.

What is DNA?

It is a list of instructions on how to replicate a cell

Where is the DNA found?

In the chromosomes which are in the nucleus of the cell

What is a gene?

It is a short piece of a chromosome which contains some of the DNA
A gene controls the production of proteins in cells
Genes determine specific characteristics eg hair colour, eye colour

What percentage of genes come from each of the parents in a zygote

A zygote gets 50% (half) of it’s genes from each parent.

What are chromosomes made of?

DNA

Where are chromosomes found?

In the nucleus of a cell

When the nucleus of a male and a female gamete (sex cell) fuse together it is known as ?

Fertilisation

Describe selective breeding

Where humans try to breed varieties of animals of plants with specific characteristics eg larger size, higher yield or better disease resistance

Give another word for variation

Differences

Variation between species is very obvious due to?

The fact that they have very different genes. Eg a cow and a tree

What does variation within a species mean?

That although the genes are similar there are some differences in colouring, size etc Eg cows come in a variety of colours and sizes

What is continuous variation within a species?

Where the characteristic you are looking at has a measurement within a range and you could plot the results from a group on a chart eg height or skin colour

What is discontinuous variation within a species?

Where the characteristic only has certain values Best example is blood groups in humans They can only be A B AB or O

What is inherited variation?

The characteristics of the offspring are a combination from both parents as our genes come 50% form each.

What is environmental variation?

Characteristics can be affected by environment as well as inheritance. Eg two tomato plants have the same inherited characteristics but if one is grown in warmer conditions with better nutrition it will produce more tomatoes. Or with identical twins if one eats a lot more they will be heavier.

Identify 4 characteristics which are only inherited and are not affected by environment at all

Hair colour Eye colour Inherited diseases Blood group

Identify 4 environmental factors which can affect the growth of plants

1.Temperature 2. Sunlight 3. Moisture 4. Soil conditions
