TODAY IN SCIENCE CLASS 1 2 3 4

TODAY IN SCIENCE CLASS… 1. 2. 3. 4. 5. Take Ch. 2 Quiz When you hand it in, please get Binder Pgs. 5 & 6 You may begin working on Pg. 6 (Your homework) USE TEXT PGS 68 & 69 We will complete Pg. 5 together as a class. FYI- We will be in the Learning Lab tomorrow!

SCIENCE CLASS TODAY: PLEASE SIGN INTO THE COMPUTER n n GO TO MY BLOG n n n http: //cobblearning. net/rudick 7/ (AFTER GOING TO MY BLOG- DO NOTHING ELSE!!) THEN GO TO EXPLORELEARNING. COM IF YOU FORGOT YOUR PASSWORD, SEE THE LINK CALLED GIZMO PASSWORDS ON THE RIGHT SIDE OF MY BLOG UNDER “PAGES”

WARM UP QUESTIONS (1 &2 on your packet) 1. 2. What are some of the structures inside a cell that help it to live and perform its role in an organism? How do you think plant cells differ from animal cells? (Hint: What can plants do that animals cannot?

GIZMOS 1. 2. Complete the Cell Structures gizmo as well as the quiz that goes with it. Be sure you are accurately filling in your corresponding worksheet in complete sentences when needed. If you finish early, try one of these Gizmos for a review of Ecology: Homeostasis (try first), Prairie Ecosystem, Forest Ecosystem, Pond Ecosystem

Cell Structures, Functions and Transport

Figure 7 -5 Plant and Animal Cells Animal Cell Section 7 -2 Cytoplasm Nucleolus Nucleus Go to Section: Cell Membrane

Eukaryotic Cell Organelles and Function Nucleus 1. n n n Nickname: “The Control Center” Function: holds the DNA Parts: 1. Nucleolus: dark spot in the middle of the nucleus that helps make ribosomes

Eukaryotic Cell Organelles and Function Ribosomes 2. n n Function: makes proteins Found in all cells, prokaryotic and eukaryotic

Eukaryotic Cell Organelles and Function Endoplasmic Reticulum (ER) 3. n n Nickname: “Roads” Function: The internal delivery system of the cell

Figure 7 -5 Plant and Animal Cells Animal Cell Section 7 -2 Cytoplasm Nucleolus Nucleus Rough Endoplasmic Reticulum Go to Section: Ribosomes Cell Membrane Smooth Endoplasmic Reticulum

Endoplasmic Reticulum n 2 Types: 1. Rough ER: n n 2. Rough appearance because it has ribosomes Function: helps make proteins, that’s why it has ribosomes Smooth ER: n n NO ribosomes Function: makes fats or lipids

n Now let’s talk about structures only found in PLANT Cells!!

Figure 7 -5 Plant and Animal Cells Section 7 -2 Plant Cell Vacuole Cell Membrane Go to Section:

Eukaryotic Cell Organelles and Function Vacuoles 7. n Function: stores water n This is what makes lettuce crisp n When there is no water, the plant wilts

Figure 7 -5 Plant and Animal Cells Plant Cell Section 7 -2 Vacuole Chloroplasts Cell Membrane Go to Section:

Eukaryotic Cell Organelles and Function Chloroplasts 8. n n Function: traps energy from the sun to produce food for the plant cell Green in color because of chlorophyll, which is a green pigment

Chloroplasts
