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
