Part 3 Plants

Question 1

What dose being a multicellular organism allow for?

Answer 1

Division of labor
Size
Interdependence of cell

Question 2

What is division of labor?

Answer 2

Cell are specialized for one particular function

Question 3

Why do multicellular organisms grow in size?

Answer 3

There internal transportation systems allow efficient exchange of materials

Question 4

What dose it mean when a organism has Interdependence of cell?

Answer 4

One cell could die and the greater organism will continue to live

Question 5

What are groups of similar cells called?

Answer 5

Tissues

Question 6

What are examples of tissues

Answer 6

Muscle, bone, blood, epithelial (skin)

Question 7

What are the two organ systems plants have?

Answer 7

Shoot and root system

Question 8

Put these five things in order of smallest to largest: tissue, organism, specially cell, organ, and system

Answer 8

Specialized cell < tissue < organ < system < organism

Question 9

Wheres the shoot system?

Answer 9

Above ground

Question 10

Where’s the root system?

Answer 10

Below ground

Question 11

What are the hair like projections on the root called?

Answer 11

Root hairs

Question 12

What is the function of root hairs?

Answer 12

Increase the surface area to maximize absorption of water and minerals

Question 13

The two systems are divided in to three types, what are these types?

Answer 13

Dermal Tissue (epidermis)
Ground Tissue
Vascular Tissue

Question 14

How do the 3 types of tissue develop

Answer 14

Via mitosis

Question 15

What the name for the region that the mitosis for the 3 types of tissue occurs

Answer 15

Meristem

Question 16

What is the dermal tissue (epidermis) on both woody and non woody plants?

Answer 16

non woody plants: A thin outer layer that covers the plant and is responsible for gas exchange

woody plants: Tissue takes the from of bark and dose the same aforementioned things

Question 17

In plants, most gas exchange occurs by diffusion through opening called ___________________.

Answer 17

Stomata and lenticel

Question 18

True or False: Lenticals are the primary way for woody plants to exchange gas

Answer 18

True

Question 19

What are lenticesl?

Answer 19

Raised spongy regions (pores) on woody plants

Question 20

Where is the stomata located?

Answer 20

leaves

Question 21

What allows for the control of the opening and closing of the stomata?

Answer 21

Guard Cells

Question 22

Why do stomata close at night?

Answer 22

To prevent water loss through transpiration (evaporation)

Question 23

True or False: Plants in hotter and dryer climates have more stomata to prevent water loss

Answer 23

False

Question 24

When stomata have a abundance of water what happens?

Answer 24

They become turgid cause them to be forced open

Question 25

What and where is ground tissue?

Answer 25

Makes up ten majority of the plants and is found beneath the epidermis

Question 26

How dose ground tissue differ from roots to leaves?

Answer 26

Roots: involved in food and water storage Leaves: Involved in photosynthesis

Question 27

What and where is mesophyll?

Answer 27

Two special ground tissue found between the upper and lower epidermis

Question 28

What is plaside mesophyll?

Answer 28

Long, rigid, rectangular cells that are tightly packed together are facing the sun - they have chloroplasts in them thus they are responsible for photosynthesis

Question 29

What is spongy mesophyll?

Answer 29

Loosely packed cells that allow for the diffusion and gas exchange. They move O2 towards the stomata and CO2 towards the plaside mesophyll

Question 30

Vascular tissue uses the _____ and _____ to transport different materials throughout the plant

Answer 30

Xylem, Phloem

Question 31

What is the propose of the xylem?

Answer 31

Move water and dissolved minerals from the roots to the leaves

Question 32

What is the propose of the phloem?

Answer 32

Transport sap (glucose and other sugars) form the leaves to the other parts of the plant

Question 33

True or Flase: cellular respiration releases glucose and oxygen

Answer 33

False It releases water, carbon dioxide, and energy

Question 34

What are the 3 types of plant transportation?

Answer 34

Transpiration Cohesion and Adhesion Root Pressure

Question 35

What is the role of transpiration in water movement in plants?

Answer 35

Transpiration through the stomata creates a tension or pull on adjacent water molecules, helping water move up the xylem

Question 36

What is transpiration?

Answer 36

Transpiration is the evaporation of water through the leaves

Question 37

How does adhesion help move water in plants?

Answer 37

Adhesion causes water molecules to be attracted to the cell walls

Question 38

How does cohesion help move water in plants?

Answer 38

Cohesion causes water molecules to be attracted to each other, pulling each other along

Question 39

What is root pressure?

Answer 39

Root pressure is the push force created when minerals are actively pumped into the root and root hairs

Question 40

How does osmosis contribute to root pressure?

Answer 40

Water follows the minerals into the root by osmosis, increasing pressure below
