How organisms grow

Why is the genetic material important?

• It allows us to do cell respiration

• It is responsible for photosynthesis in plants

• It allows organisms to increase their populations

• It allows characteristics to be passed on from generation to generation

In some living organisms, the genetic material is in the form of DNA.

• True

• False

The genetic material is found in the endoplasmic reticulum (ER).

• True

• False

Organisms that have two copies of each molecule of DNA (chromosomes) are called:

• haploid

• triploid

• tetraploid

• diploid

Organisms that have only 1 copy of each molecule of DNA are called:

• haploid

• triploid

• tetraploid

• diploid

Humans are:

• haploid

• triploid

• tetraploid

• diploid

Human gametes are:

• haploid

• triploid

• tetraploid

• diploid

Moss sporophytes are:

• haploid

• triploid

• tetraploid

• diploid

Moss gametophytes are:

• haploid

• triploid

• tetraploid

• diploid

Moss sporophytes produce spores through:

• meiosis

• mitosis

• binary fission

• another less common type of cell division
