But So Far….

the basics
The basics
  • Definition of an organism-is any individual living thing. All organisms are made of one or more cells.

-cells are the basic unit of life.

slide3
DNA
  • Genetic material passed from one generation to the next,

-and how do we know this?

microscopes
microscopes
  • In addition to scientific testing of theories and shared knowledge, we can now see it.

-a great enhancement to help support the cell theory.

CELL THEORY-all organisms are made of cells, all cells are from other living cells, and the cell is the most basic unit of life.

the basics again light
The basics again---light
  • With light comes life: phototrophs vs. heterotrophs
  • Photo—light + troph—how it gets its food or energy
  • So, green plants get their food from the light or sun (photo|trophs).
and why green
And why green?
  • They have chlorophyll a green plant pigment which enables photosynthesis
  • in the cell organelle called the chloroplast
after all then
After all, then….
  • Herbivores versus carnivores
  • Plant eaters……or……meat eaters,
  • Or omnivores—eating both plants and meat (and chips, too),
  • More basics soon…now, review sheets, flashcards, notebooks and exit slip

(Friday’s test is no notebooks allowed)
