Back 34

eukaryotic cells that have chloroplasts and a cell wall

Front 35

animal cell

Back 35

eukaryotic cell that does not have a cell wall or chloroplasts

Front 36

organelle

Back 36

a specialized part of the cell that has it's own function

Front 37

nucleus

Back 37

is the brain of the cell- contains all the DNA

Front 38

mitochondria

Back 38

maze like organelle that produces the ATP the body needs through respiration.

Front 39

cytosol

Back 39

a jelly like substance inside the cell

Front 40

chloroplast

Back 40

a coin like organelle that only exists in plant cells so they can complete photosynthesis

Front 41

Cell membrane

Back 41

An organelle considered the bouncer of the cell because it balances what can go into and out of the cell

Front 42

Photosynthesis

Back 42

Sunlight+Water+ Carbondioxide = Glucose + Oxygen

Front 43

Passive transport

Back 43

High --> Low
Do not need ATP

Front 44

Active Transport

Back 44

Low--> High
Uses ATP

Front 45

Diffusion

Back 45

transfer of materials in and out of the cell that goes from a high or a low concentration
Glucose, water can diffuse
Starch and proteins cannot

Front 46

Osmosis

Back 46

transfer of water in and out of the cell

Front 47

stomata

Back 47

2 special cells that regulate the amount of carbobn dioxide and oxygen that enter and exit that leaves

Front 48

Why is photosynthesis important?

Back 48

Because it helped change the earths atmosphere by creating oxygen so humans can live

Front 49

Chlorophyll

Back 49

The green substance in chloroplasts that helps plants capture sunlight so they can finish photosynthesis.

Front 50

what is locomotion?

Back 50

the ability of organisms to move themselves.

Front 51

What is transport?

Back 51

the ability to move materials from one area to another.

Front 52

What is the difference between locomotion and transport?

Back 52

locomotion is moving yourself and transport is moving something else.

Front 53

What are some mechanisms organisms use for locomotion?

Back 53

psuedopods, flagella, cillia, legs.

Front 54

In the beginning of time the earth was mostly made of nitrogen and carbon dioxide. How did photosynthesis change that?

Back 54

Plants changed the carbon dioxide into oxygen and made it possible for humans to grow.

Front 55

How does photosynthesis and respiration work together?

Back 55

the waste product of one is the raw material for the other.
