7th Grade Review Packet
Science Standards and Vocabulary
The following will be a list of the 7th grade science standards and objectives we have covered throughout
the year. For each standard please write down the information you have learned about the standard,

7. Organs are the basic component parts of an organ system. How does an organs structure and
function influence their role in the organ system that they belong in?

are met by tissues and organs.

or objects? Also draw what an onion cell looks like.

organelles: cell wall, mitochondria, cell membrane, nucleus, chloroplast, and cytoplasm. For
each cell organelle please include an accurate definition of the organelles function.
