Question 15

What kingdom does yeast belong to?

Answer 15

Kingdom fungi

Question 16

Is yeast a unicellular or multicellular organism? Explain why?

Answer 16

Yeast is a unicellular organism because it is only made up of one cell

Answer 17

An environment that is warm, moist and has a supply of air and food.

Question 18

Question 21

What are the byproducts produced when yeast is added to sugar

Answer 21

Yeast and glucose –> CO2 and ethanol

Question 22

What is intophase?

Answer 22

Resting phase and is where the DNA doubles

Question 23

What is prophase?

Answer 23

Nuclear membrane disappears and the chromosomes become visible

Question 24

What is metaphase?

Answer 24

Chromosomes line up down the equator of the cell

Question 25

What is anaphase?

Answer 25

Spindle fibres pull chromosomes in half then they move to opposite sides of the cell and move away

Question 26

What is telophase?

Answer 26

All chromosomes regroup together and the cytoplasm splits in half, a new nuclear membrane forms and 2 new identical cells are formed. These are called daughter cells
