Open Ended

What is one or more PURPOSES of reproduction?

Reproduction with 1 Parent

• Offspring identical to parent

• Offspring identical to each other

• Begin as a single cell and grow by dividing

Reproduction with 2 Parents

• Each parent makes reproductive cells with half of their genes

• Once cell from each parent fuse and combine their genes/DNA

• Offspring differ from parents

• Offspring differ from each other

Multiple Choice

Which is true of this type of reproduction?

• The offspring have identical genes

• Each offspring has a different combination of genes

Heredity

• Cells contain chromosomes with DNA

• Cells copy their DNA and then when they divide, each cell has identical DNA

• DNA tells which types of cells should reproduce

Multiple Choice

What is a gene?

• An entire chromosome that codes for a trait

• a piece of clothing

• a piece of a DNA on a chromosome that codes for a trait

• Chemical messengers in your brain that code for a trait

Multiple Choice

What is this?

• A gene

• DNA

• A chromosome

• A cell

Multiple Choice

The passing of DNA from parents to offspring

• Generation
• Heredity
• Inheritance
• Traits

Multiple Choice

What is the RESULT of a plant reproduction?

• The offspring have identical genes

• The parents make reproductive cells with only half of their genes

• Each offspring has a different combination of genes

• Two parents are required to produce the offspring
