computer• You may work with a partner (no more
than 2 people together)• Go to website• Use website to complete the review • You have 45min to complete
OrganellesNucleus
◦Controls cell activities
Mitochondria:◦Makes energy!◦Cell Respiration
Chloroplast:◦Makes food for plants◦Photosynthesis
OrganellesRibosome
◦Makes protein
Cilia/Flagella◦Both help cell move◦Cilia= hair-like Flagella= tail
Cell Membrane:◦Controls what enters/leaves the cell
Nucleus
Cell Membrane…What’s it made of?
Ribosomes
Mitochondria Chloroplast
Cell Wall…What’s it made of?
Transport of MaterialsCell Membrane
◦Controls what enters/leaves the cell
Circulatory System◦Carries oxygen, nutrients to cells◦BLOOD!
Vascular Tissues◦Carries water, nutrients to plant cells
Body SystemsCirculatory System
◦Carries oxygen, nutrients to cells◦BLOOD!
Reproductive System◦Makes eggs/sperm (gametes) to pass
on genes to next generation
Excretory System◦Removes bulk waste
Body SystemsNervous System
◦Controls everything, Controls movement
Endocrine System◦Hormones◦“chemicals that regulate/act at
different sites in the body”
Body SystemsSkeletal System
◦Attaches to muscles for movement◦Bones
Muscular System◦Attaches to bones for movement◦Muscles
Body SystemsDigestive System
◦Breaks down food and nutrients
Respiratory System◦Breathing◦Takes in Oxygen, releases CO2
Asexual ReproductionMitosis
◦Cell division in body cells◦To make more IDENTICAL cells
Binary Fission◦Division IN BACTERIA
Cells After Asexual Reproduction◦IDENTICAL to original cell◦Cloning
HomeostasisDefinition
◦Maintaining stable internal conditions
◦Keeping everything in the body “normal”
Examples:◦Body temperature◦Blood sugar◦Blood pressure
Diffusion/OsmosisSelectively Permeable
◦Only allows certain things to move through ◦The cell membrane is selectively permeable
Diffusion◦Molecules move from high to low
concentration◦No energy required
Osmosis◦WATER moves from high to low concentration◦No energy required
