We're starting off the second trimester learning how cells do the many complicated things they do. We're going to cover quite a bit of material in this unit, and, like last time, we're going to skip around a bit in the textbook.
- We start back in Chapter 3 with section 3, the one we skipped in our last unit. We're going to learn the basics about the kinds of chemical compounds that make up living organisms, carbohydrates, lipids, proteins, and nucleic acids.
- Then we're going to jump back to Chapter 9. This time, we'll look at Section 1 to explore the weird world of viruses. Viruses are basically just DNA on wheels, so it fits in well after learning about nucleic acids.
- Next, we'll go on to Chapter 4 and stay there for the rest of the unit. (That'll be nice, right?) First, we'll learn about the chemistry of photosynthesis where plants use the sun's energy to make the carbohydrates that animals need to live.
- In Section 2, we find out what happens to that yummy glucose. It's called respiration and it's how animal cells use glucose to make the energy they need to do their various animal cell-type jobs.
- Section 3 is where we start learning the function of that most basic stuff of life: DNA. We'll find out how cells produce other cells, copying the precious DNA every time to pass it on to the next generation of cells.
- In Section 4, we'll just learn a bit about how cells in multicellular organisms become different from one another.
