Growth And Development

How do you measure growth in an animal or a plant?

Hahahahahaha.... No. Do you know how much that joke has been overused? No, don't measure it with a ruler.

"Growth is an increase in Size or Mass"

Learn that, should make it much simpler.

Measure it in 3 ways:

1. Size (length and width... Go on, make a penis joke)
2. Wet Mass (Organisms have loads of water, so why not measure it with it in?)
3. Dry Mass (Oh... I take that back. You can take it out and weigh it aswell.)

Why do things grow?

• Cell differentitation (the cell becomes specialised. Like a cell university degree)
• Cell Division (Say hi to Mitosis again! That's miTosis... Not meiosis.)
• Cell elongation (where a PLANT cell expands. PLANT CELL. PLANT.)
