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 ____________________________________.
