2. ORGANELLES: STRUCTURE & FUNCTION

ORGANELLE DIAGRAM PLANT/ ANIMAL/

BOTH

FUNCTIONS

chloroplast

vacuole

mitochondria

plantTraps sunlight; site of photosynthesis

both Stores water, food, and waste products

both Stores and releases energy

2. ORGANELLES: STRUCTURE & FUNCTION

ORGANELLE DIAGRAM PLANT/ ANIMAL/

BOTH

FUNCTIONS

cell membrane

cell wall

cytoplasm

nucleus

both Surrounds and protects cell; allows materials to enter and exit the cell

plant Supports and protects plant cell; gives it shape

both Fills cell and surrounds other organelles

both Acts as the “brain” of the cell; directs cell’s activities; contains the DNA

3. C-T-O-S-O

EXAMPLES

CELL White blood cell, skin cell, epithelial cell, cardiac cell

TISSUE Muscle tissue, brain tissue, skin tissue

ORGAN Heart, lung, kidney, liver

SYSTEMCirculatory system, respiratory system, digestive system

ORGANISM JJ Watt, bear, dog, bobcat, horse,

4. What is the cell theory?

The cell is the basic unit of structure (shape) and function (job) of living things.

All living things are made of cells. All cells come from other cells.

5. Prokaryote vs. Eukaryote

•No organelles•No membrane nucleus•Bacteria

•Unicellular•Respond to environment•Grow•Reproduce•Made of cells

•Organelles•Defined nucleus•Multicellular

6. What is photosynthesis?

The process in which plants make their own food.

7. Equation for Photosynthesis

8. Reactants & Products of Photosynthesis

Reactants: (What reacts with the sunlight?)

Carbon dioxide and water Products: (What gets produced, or made?)

Glucose and oxygen

9. What product gives the plant energy?

NO! NO!

NO! Glucose—YES!

10. What is turgor pressure?

The amount of force the vacuole exerts against the cell wall

Full vacuole = high turgor pressure = healthy plant

Less full vacuole = low turgor pressure = wilted plant

11. Turgor Pressure Lab

Lab item Salt water Plain water

Potato

Celery

Elodea

Mushy textureLost mass

Firm texture

Gained mass

Became soft, floppy Remained firm

Cells appeared darker green; chloroplasts were close together

Cells had light areas with chloroplasts along cell wall

12. Cells with different turgor pressure

13. Tropism

A plant’s response to a stimulus

Ex: Spillane’s band plays

(stimulus)...

And these plants sing

(response)!

14. TropismsPhototropism

Geotropism

Hydrotropism

Thigmotropism

Plant grows toward light

Plant’s response to gravity (ex: roots grow down)

Plants roots grow toward water

Plant wraps around objects it touches

15. Homeostasis

Homeostasis : the process by which an organism maintains equilibrium (or balance) internally despite changes in the external environment.

H o m e o s t a s i s

It stays as it is.

Study and you’ll do fine!
