The nucleus

Growth and repair, producing identical cells

To make gametes with half the chromosome number

To introduce variation

To digest food

Two cells with the full number

Four cells, each with half the number

Two cells, each with half the number

Four cells with the full number

The acrosome

The tail

Many mitochondria

The haploid nucleus

The transfer of pollen to a stigma

The growth of a seed into a plant

The division of a cell into two

The fusion of a male and a female gamete to form a zygote

Large, brightly coloured and scented with nectar

Small, dull and unscented with feathery stigmas

Producing huge amounts of light, smooth pollen

Having stigmas that hang outside the flower

Sticky stigma inside the flower

Feathery stigmas hanging outside to catch pollen in the air

Bright petals and strong scent

Dominant

A whole chromosome

It has two identical alleles

It has three alleles

It has no alleles for that gene

It has two different alleles for that gene

3:1

1:1

9:3:3:1

All the same

Human height

Blood group (A, B, AB or O)

Body mass

Hand span

Because offspring are genetically identical to one parent

Because no genes are involved

Because gametes from two parents combine, mixing genetic material

Because mitosis copies the DNA exactly
