Multi-Cellular Notes
What are multi-cell organisms?
Organisms that consist of more than _________________________
Each multi-cellular organism consists of _________________________________________
What are organelles?
A tiny structure that carries out a specific function within a cell.
Examples: ____________________________________
Cell Wall:
rigid layer of non- living material surrounding _________________________________________
Only in plant cells _______________________________ &
___________________________________ cell
Cell membrane:
Structure that controls __________________________________________________________.
In ______________________________cells Everything must pass through membrane to enter or exit Only lets in things needed and blocks
_______________________________________________.
Nucleus:
_________________________________ the functions in the cell (called “the ______________”)
Nuclear membrane:
separates nucleus from _________________________________________________
Chromatin:
thin, floating strands that contain ____________________________________________
Cytoplasm:
A gel-like region between the cell membrane and nucleus that contains _____________________________ & _________________________________________
Mitochondria (MIGHTY Mitochondria):
Rod shapes that are called the “________________________________________” of the cell. __________________________________ is produced here & converted into “power”
Endoplasmic Reticulum:
A maze of passageways that carry _________________________________ throughout the cell and____________________________________________ nutrients.
Ribosomes: (Ribs give you PROTEIN)
Small grain-like bodies that float in_________________________________ and attach to ER.
They are called the “factories” that produce________________________________.
Golgi Bodies: (Gmail)
Flattened sacs and tubes that receive protein from _________________________, packages them, and sends _______________________________________to the cell. (Like a mail room)
Vacuoles:
Storage areas for ______________________________, materials, & _____________________________________
Large, water-filled sacs. ______________________in plant cells, ________________________________in animal cells
Lysosomes: (Lysol cleans)
_______________________________________ materials (digestion)
o Cell’s “clean up crew” found mostly in __________________________________cells
Chloroplasts:
large green structures that float in cytoplasm makes the cell_____________________________________ captures energy from sunlight to
create _____________________________________________ only in________________________________________ cells
What are specialized cells?
Cells with a specific ___________________________________ Cells with the same function organize together to create something “grander” Cells with same function gather together to create _____________________________________
Bacteria Cell VS Plant and Animal Cell:
Bacteria cells are____________________________________ than plant and animal cells. Bacterial cells DO NOT contain a __________________________________________ ______________________________ in bacteria cells are found in cytoplasm
Plant VS Animal:
Plant cells have chloroplast and ____________________________________ Animal cells have ____________________________________.
