Plants and animals have structures for respiration, digestion, waste disposal, and transport of materials. 5th grade Life Sciences

Plant and Animal Cells Many multicellular organisms have specialized structures to support the transport of materials.

Circulatory and Transport Systems Blood circulates through the heart chambers, lungs, and body and how carbon dioxide and oxygen are exchanged in the lungs and tissues.

To move from one place to another. transport To move from one place to another. 5th Life Sciences Lesson 2

circulatory system Organs that “move” or transports blood, nutrients, and other materials throughout the body. 5th Life Sciences Lesson 2

Small blood vessels that carry oxygen rich blood throughout the body. capillary Small blood vessels that carry oxygen rich blood throughout the body. 5th Life Sciences Lesson 2

veins Medium blood vessels that carry blood low in oxygen from the body back to the heart. 5th Life Sciences Lesson 2

Large blood vessels that carry blood from the heart to the body artery Large blood vessels that carry blood from the heart to the body 5th Life Sciences Lesson 1

Transports water and nutrients through the plant vascular tissue Transports water and nutrients through the plant 5th Life Sciences Lesson 2

Transports food throughout the plant. phloem Transports food throughout the plant. 5th Life Sciences Lesson 2

Moves water and nutrients from the roots up to the leaves. xylem Moves water and nutrients from the roots up to the leaves. 5th Life Sciences Lesson 2

phloem and xylem 5th Life Sciences Lesson 2

Respiratory and Circulatory Blood circulates through the heart chambers, lungs, and body and carbon dioxide and oxygen are exchanged in the lungs and tissues. Plants use carbon dioxide and energy from sunlight to build molecules of sugar and release oxygen. Plant and animal cells break down sugar to obtain energy, a process resulting in carbon dioxide and water.

Process by which plants make food. photosynthesis Process by which plants make food. 5th Life Sciences Lesson 3
