this week in science we started a new unit on reproduction. on the first day we go three questions. they were

1. how do organisms reproduce?
2. how do cells reproduce?
3. how is sex different then reproduction?

we started with the 3rd one. sex is like a cell delivery service. it is 50% sperm and 50%egg. it doesn't necessarily end with of spring.

then the answer to the first on is by using sperm and egg. then it splits into two parts.

then the second answer is by splitting the cell makes a copy of org.

then a reproducing cell has two nuclei. a cell that is suppose to split has a very big nucleus. a regular cell has a regular size nucleus.

there are 5 stages of mitosis. they are...

• inter phase
• pro phase
• meta phase
• alphas
• televise
• cytocanisis
