Zamora, Grade 5 - Science, Chapter 3 Test

Front 1

What are the smallest living parts of plants and animals?

Back 1

The cells

Front 2

What do all cells need?

Back 2

All cells need food

Front 3

What part of the cell directs the cells activities?

Back 3

The nucleus / brain

Front 4

What job does the roots of a plant carry out?

Back 4

It anchors the plant. It takes water from the soil

Front 5

How does sugar get from the plants leaves to the rest of the plant?

Back 5

Phloem takes it there

Front 6

How do the nutrients in a plant root system get to the leaves of the plant?

Back 6

Xylem

Front 7

What green substance allows plants to make their own food?

Back 7

Chlorophyll

Front 8

What is produced by photosynthesis?

Back 8

Sugar / Food

Front 9

What process do plants go through to release energy? What materials are used in this process?

Back 9

Cellular respiration

Sugar and carbon dioxide

Front 10

Organs work together in an organ system.... True or false?

Back 10

True

Front 11

The mouth is part of the digestive system. True or false?

Back 11

True

Front 12

During _______, cells of organisms release energy from food

Back 12

Cellular respiration

Front 13

________ carries water and minerals throughout a plant

Back 13

Phloem

Front 14

________ carries water and minerals throughout a plant

Back 14

Xylem

Front 15

During _____, plants make sugar and release oxygen

Back 15

Photosynthesis

Front 16

A group of cells that work together to perform the same function is called a(n) _____.

Back 16

Tissue

Front 17

The plant cell structure that has chlorophyll is called a(n) _____.

Back 17

Chloroplast

Front 18

The ______ is a cell structure that stores water and other substances

Back 18

Vacuole

Front 19

_____ is a green substance that is needed by plants to make food

Back 19

Clore Phil

Front 20

What are some ways cells help an organism?

Back 20

The cells make tissue and tissue makes organs and they all work together in groups.

Front 21

Explain the role of phloem in plants and how phloem forms bark on a tree.

Back 21

Phloem tubes carry sugar away from the leaves. The sugar is dissolved in water. Phloem carries this mixture of sugar and water from the leaves throughout the plant. The dead phloem protects the new phloem. When that new phloem dies it forms more bark.

Front 22

A greenhouse is filled with air that contains more carbon dioxide than normal air has. How might photosynthesis and plant growth be affected?

Back 22

Plant growth will be affected because photosynthesis and plant growth usually have the right amount of Carbon Dioxide but if they have more they have to split it up more
