Biology - Plant system

Question 1

Do plants create their own food? How?

Answer 1

Yes, due to photosynthesis

Question 2

3 functions plants perform

Answer 2

1. Gas exchange with surroundings
2. Internal transportation system to move water & nutrients
3. A method of reproduction

Question 3

2 main body systems

Answer 3

1. Root System
2. Shoot system

Question 4

Where is the root system in a plant?

Answer 4

Consists of organs that grow below the ground

Question 5

Can root system part be exposed to air (aerial)?

Answer 5

Yes

Question 6

3 things the root system is responsible for:

Answer 6

1. Anchoring the plant to the ground
2. Absorption of water/minerals from the soil
3. storage of food (glucose) ex. root vegetables

Question 7

where do the parts of a shoot system grow?

Answer 7

Above the surface

Question 8

2 things the shoot system is responsible for

Answer 8

1. Photosynthesis
2. Flower production for reproductive purposes

Question 9

3 parts the shoot system is composed of

Answer 9

1. Leaf
2. Flower
3. Stem

Question 10

Leaves: In what organelle does photosynthesis occur in?

Answer 10

Chloroplasts

Question 11

What do chloroplasts in leaves do?

Answer 11

They absorb light energy (sunlight)

Question 12

Photosynthesis (food) formula:

Answer 12

light energy + CO2 + water -> oxygen + glucose

Question 13

3 functions leaves include

Answer 13

1. support
2. protection
3. reproduction & attraction

Question 14

Why does a plant put energy into producing a flower?

Answer 14

Reproduction

Question 15

what part of the shoot system includes male and female structures?

Answer 15

Flowers

Question 16

Is pistol a male or female reproductive system? what does it contain of?

Answer 16

Female. Made up of Stigma, style and ovary

Question 17

How does the female reproductive system work?

Answer 17

Once the egg/ovule has been pollinated it becomes a seed inside the protective of the fruit

Question 18

Is stamen a male or female reproductive system? what does it contain of?

Answer 18

Male. Made up of Anther and Filament where the pollen is produced

Question 19

What provides a way to transport materials to and from the roots, leaves, flowers, and fruit?

Answer 19

Stem

Question 20

What do stems store? example

Answer 20

Glucose / water

example:
cacti holds water in their stems during droughts

Question 21

3 types of tissues in plants

Answer 21

1. dermal
2. vascular
3. Ground

Question 22

what is a dermal tissue?

Answer 22

The outermost layer of cells that covers and protects the plant; barrier and prevents from water loss

Question 23

what is a vascular tissue?

Answer 23

transports water, nutrients, and other chemicals throughout the plant

Question 24

What are the 2 types of vascular tissues?

Answer 24

Xylem & Phloem

Question 25

what does xylem do?

Answer 25

conducts water and dissolved minerals UPWARD from the roots to the rest of the plant.

Question 26

what does phloem do?

Answer 26

1. Transports sugars and other organic molecules produced during photosynthesis from the leaves to other parts of the plants 2. Two-way flow

Question 27

What is it called when all the tissues between dermal and vascular, compose another tissue?

Answer 27

Ground tissue

Question 28

what does the ground tissue store: In roots

Answer 28

Storage of carbohydrates

Question 29

Where is storage and support provided in ground tissue?

Answer 29

Stems

Question 30

What type of cell does a plant have that can differentiate into specialized TISSUES?

Answer 30

Meristematic Cells

Question 31

What will meristematic cells in a plant do?

Answer 31

Continue to divide throughout the life of the plant

Question 32

Which 2 spots are meristematic cells located in?

Answer 32

1. Apical meristem - located at the tip of shoots and roots allowing a plant to grow LONGER 2. Lateral meristem - located in the stem & roots allowing a plant to grow WIDER

Question 33

Why's a leaf's surface a waxy cuticle?

Answer 33

To prevent water loss

Question 34

What cells create openings in a leaf's cuticle?

Answer 34

Guard Cells

Question 35

What is the motive of a guard cell?

Answer 35

creating openings that allows carbon dioxide to enter the leaf for use in photosynthesis

Question 36

What are the openings in the leaf called?

Answer 36

Stomata

Question 37

Where is the stomata located to prevent water loss?

Answer 37

They are located on the underside of leaves to reduce water loss through evaporation; allowing the upper surface to be used for photosynthesis
