The word cell is used in many contexts (ways). List the different ways cell is used (outside of science

class).

Cells Organelles:

Review

Organism- Lion, butterfly, frog, gnat etc….Organ system- Cardiovascular, Skeletal,

Integumentary (skin, nails and hair) etc…Organ- Heart, liver, spleen, brain etc….Tissue- Connective, muscular tissue etc….Cells- Smallest unit of life, no cells =no life!!

What is the most basic unit of language/life?

Cells= Words Tissue= Phrases or sentences Organ= Chorus, hook or lyrics.Organ system= A complete song, lyrics, hookOrganism= Complete album art work,

production, songs.

Today we are going to study the “words”

EQ

What are the functions of major cell organelles?

For example

Organelle- a specialized structure of a cell ( the generic term for anything in the cell)

Organelle= Cell parts Ribosomes, Nucleus, cytoplasm

Color: Green

Chloroplast- Where photosynthesis occurs, converts energy for the cell. Found only in plants.

Color: Green

Cell walls- Found only in plants protects and supports plant cell.

Vacuoles- storage unit of cell, stores food, water and waste significantly larger in Plant cells

Plant Cell

Science Starter 8-23-13

1. What is the structure that most cells have? 2. If you have STILL not finished your hand, do

so now.3. I’m throwing away all the papers left in the

room this afternoon

4. If you have finished your hand, you may SILENTLY on something else or read.

Color: YOU Choose. (NOT GREEN)

Cell membrane-- thin semi-permeable membrane that surrounds the cytoplasm of a cell. It allows certain substances into the cell, while keeping other substances out

Mitochondria- Energy/Power Center of cell

Nucleus- stores DNA, Control center (Brains) of cell

Ribosomes- assembles proteins by translating messenger RNA (found all throughout the cell)

Cytoplasm- fluid that fills a cell, clear and gel-like appearance. Helps move materials around the cell.

Endoplasmic reticulum

E.R- packaging systemRough E.R.-

Presences of ribosome (proteins)

Smooth E.R.- absences of ribosome (stores steroids)

 Golgi appartatus-packaging and shipping

molecules

Explain in your words what each function is

1. Cell wall and Cell membrane2. Cytoplasm3. Mitochondria4. Chloroplast5. Nucleus6. Chromosomes7. Vacuole

Draw OR Act out your organelle and explain it’s function.
