Question 1

Plants are

Answer 1

multicellular organisms

Question 2

Two distinguishing features
they have more

Answer 2

complex systems than animals

Question 3

Plants are divided into two main systems

Answer 3

Root Systems
shoot systems

Question 4

The root system in a flowering plant typically grows

Answer 4

below ground

Question 5

The roots of the plant have three main functions

Answer 5

-anchor the plant
-they absorb water and nutrients
-storage (they are very dense)

Question 6

Roots have long been a useful source of

Answer 6

foods
-sweet potatoes

Question 7

Shoot System

The shoot system in a flowering plant typically

Answer 7

grows above ground

Question 8

The shoot system consists of the:

Answer 8

Leaf

Flower

Stem

Question 9

The structures of the shoot system have two
main functions

Answer 9

site of photosynthesis
transportation
reproduction

Question 10

The leaves of a plant are the main structure for

Answer 10

photosynthesis

Question 11

The cell structure that performs photosynthesis is the

Answer 11

chloroplast

Question 12

The chloroplast have thylakoid filled with

Answer 12

chlorophyll

Question 13

Stacks of thylakoid are called

Answer 13

grana

Question 14

Why do plants do cellular respiration?

Answer 14

to produce gluceus

Question 15

Plant breathes using it’s

Answer 15

leaves

Question 16

Flowers are specialized structures developed

Answer 16

for sexual reproduction

Question 17

They contain male or female reproductive
structures, or sometimes

Answer 17

both

Question 18

Male reproductive structures produce

Answer 18

pollen
grains

Question 19

Female reproductive structures produce

Answer 19

eggs

Question 20

The Stem
The flowering plant stem has several functions
The stem functions…

Answer 20

as structural support

Question 21

The stem contain

Answer 21

vascular tissue (humans have arteries and veins)
(helps to transport water and nutrients)

Question 22

Plants have two types of vascular tissues

Answer 22

Xylem
phloem

Question 23

There are three main types of plant
tissue

Answer 23

Dermal Tissue (protection, prevent water loss)

Vascular Tissue (transport) (2 types)

Ground Tissue (storage, photosythesis)

waxy cuticle

Question 24

Plants have a characteristic substance on their leaves

Answer 24

waxy cuticle helps to prevent water loss by having water proofing on the leaves

Question 25

Identify the two (2) main systems of plants. How is each system important to sustaining the
plant’s life?

Answer 25

Root System: absorbs nutrients from soil
Shoot System: undergoes photosynthesis; parts are for reproduction

Question 26

What are the main functions of the leaf, flower, and stem of a plant?

Answer 26

Leaf: photosynthesis
Flower: reproduction
Stem: structural support

Question 27

What cell organelle would you expect to see an abundance of in cells of a leaf? Why?

Answer 27

Chloroplasts: completes photosynthesis (the site of photosynthesis is in the leaf)

Question 28

4. What are the three (3) types of tissues found in plants?

Answer 28

Dermal
Ground
Vascular

Question 29

5. Unlike animals, plants are unable to move. What are two (2) ways plants obtain the nutrients
   required to survive?

Answer 29

Roots absorb nutrients from the soil
Leaves undergo photosynthesis to produce glucose
