Warm-Up

• How are plants and animals the same?• How are plants and animals different?• Based on your reading and your work

from yesterday, do you think that plant cells and animal cells contain the same structures?

• Using page 41 in your Science Book……–Observe the plant cell and animal cell–Determine which structures a plant cell has

that are not found in animal cells. • Turn to page 45 in your Science Book……–Read page 45 and Answer Question #3 at the

bottom of the page.–Copy the picture on page 45 in your

notebook

Writing Prompt• There are differences between the structures

of the cells of plants and animals. Explain why a plant cell needs a cell wall and chloroplast but animals cells do not?

• At LEAST 5 complete sentences.

Warm-Up: November 6, 2013

• List the 7 organelles & next to each one indicate whether it can be found in plant cells, animal cells, or both.

Warm-Up : Nov. 15, 2013

• Explain Diffusion & Osmosis. •Draw a picture to

represent diffusion.

Warm-Up

•What’s the difference between plant cells and animal cells?

Cells

Like a factory……….

Animal Plant

Cells Different Types, draw and label parts

• Cells are the smallest LIVING unit of life!

Cells

• smallest unit of life that is capable of performing life functions

COMPARING CELLS

• The size & shape of a cell relates to its function. (job it does)

Cells contain…..

Organelles

Organelle

• Cell structure that carries out specific cell functions

Organelles to learn…..

• Cell Wall• Cell Membrane• Cytoplasm• Nucleus• Vacuole• Chloroplasts• Mitochondria

Plant Cells Have

• Chloroplast-with chlorophyll (makes them Green)

• Cell Wall• LARGE vacuole• Cytoplasm• Mitochondria• Cell Membrane• Nucleus

Animal Cells have

• Small (if any) vacuoles• Cytoplasm• Mitochondria• Cell Membrane• Nucleus

Think…..

• Why would animal cells not need a cell wall, what do humans/animals have for support that plants don’t.

• Why would Plants need a LARGE vacuole…how do humans/animals get food/water vs. plants

• Why do plant cells have chloroplasts?

Plant Cell Vs. Animal

PLANT CELL ANIMAL CELLRigid structure due to cell wall provides support

No Cell wall, edges are wiggly

Has CHLOROPLASTS, where chlorophyll makes food, Usually green in color

Doesn’t make food, no chloroplast

Has LARGE VACUOLE, helps to provide shape and hold nutrients until next rain

Small or no vacuoles present, can get food/water when needed

• Found ONLY in plant cells!• protects the cell• gives shape• is made of cellulose• A cell wall is found in plants, algae, fungi, &

most bacteria.

CELL WALL

CELL MEMBRANE

• Outer covering, protective layer around ALL cells

• For cells with cell walls,the cell membrane is inside the cell wall

• Controls what enters and leaves a cell

Diffusion

• One way materials move across the cell membrane– Molecules of sugar or water

• Molecules- smallest particle of a substance with the properties of that substance

• Move from higher concentration to lower concentration

Osmosis

• Diffusion of water across a membrane

CYTOPLASM

• gel-like inside cell membrane• Made of mostly water• Organelles embeddedIn the cytoplasm

NUCLEUS

• Control center of the cell

• Contains genetic material (DNA)

VACUOLE

• Temporary storage center• Some store water• Others store waste products until they can be

eliminated (or expelled/released) from the cell

CHLOROPLASTS

• Found ONLY in plant cells!• Sites where photosynthesis takes place• Contain chlorphyll used to make food

MITOCHONDRIA

• Energy producing sites of the cell• “powerhouse” of the cell• Where respiration takes place

Rubric for Plant Cell Travel Brochure

• You must make a travel brochure of a plant cell. Your travel brochure must include:

• 7 vocabulary words(Cell Wall, Cell Membrane, Cytoplasm, Nucleus, Vacuole, Chloroplast, and Mitochondria) Each word has to represent something at whatever park, mall, or game you come up with.

• 5 points per word• Definitions or explanations of each of the words• 5 points per definition • Colored Drawing of the Plant Cell• 25 points for colored picture• * 5 points for having it on copy paper•
