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…..

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 CELL Rigid 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 embedded In 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
