Animal and Plant Nutrient Transport
Remember how Animals Absorb in their Intestines?
Blood Vessels
Arteries- lots of Oxygen
Veins- lots of CO2
Capillaries –little vessels
Blood
Functions Transports gases, waste,
enzymes, hormones, nutrients, white blood cells, clotting proteins
Maintains Body temp
Removes toxins
Electrolytes and Water
Composition of Blood
Red blood cells Hemoglobin for
binding…
White blood cells Immunity to do what?
Platelets Clotting to stop blood
loss
Plasma Water! Proteins!
Minerals! Hormones!
Who pumps it?
The heart Four chambered
Double pump
To the lungs then to the body
Blood pressure is kept normal by the rhythmic beating of the heart

What else?
Lymphatic vessels Shown in green
They return excess water that leaked out of the vessels during transport
Animal Transport System
What are the functions of blood?
What do blood vessels carry?
What does the blood carry in it?
What’s the difference between veins and arteries?
What pumps the blood?
Where do the blood get oxygen from?
Where does the blood get water from?
Where does the blood get nutrients from?
What’s the big deal?
Why is it important for animals to have a circulatory system?
Discuss as a group
Here’s the question…
Do you think that plants have a system to circulate their materials?
Do you think it’s the same as in animals?
Plant Transport System
Dermal Tissue Epidermis
Cuticle
Ground Tissue Mesophyll for
photosynthesis
Storage
Vascular Tissue Transport of water,
minerals and nutrients
Types of Vascular Tissue
Type #1
Xylem
Dead cells with only cell wall
Transports water and minerals from roots to leaves
Transpiration
Types of Vascular Tissue
Type #2
Phloem
Living cells that uses active transport
Transport sugars up and down (depending on need)
Vascular Tissue
Transport in Plants
Movement of WaterWater & mineral nutrients travel up through the
______
Water gets pulled up the stem from the roots as it evaporates out through the leaves via the stomata - this is known as ____________
Water is able to move up the stem by cohesion – tension theory
__________– water molecules stick together
__________– water molecules stick to the sides
Pressure from the roots forces the water up the stem
Water Movement
Your Assignment
Explain how the animal and plant systems transport their nutrients around by comparing the two organisms.
CER!
Work as a group to come up with an outline and write on your poster board!
Make it good, your fellow students will be critiquing it!
