Onward We Go

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.


Onward we go
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)
