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!
