Chapter 35- Structure and function of flowering plant

Question 1

What does the shoot system consists of?

Answer 1

1. stems

2. leaves.

Question 2

What is the function of stem?

Answer 2

Its produces branches, leaves, and reproductive structures.

Question 3

What is the leaves?

Answer 3

They are flattened structures that emerges from stem; most function in photosynthesis.

Question 4

What does the root system consists of?

Answer 4

1. Root
2. rhizome
3. tubers

Question 5

What is the function of rhziome?

Answer 5

it is a horizontal underground stem that may give rise to new shoots.

Question 6

What is the function of tubers?

Answer 6

it is enlarged underground stem that store food, it may give rise to new shoots.

Question 7

What meristem give rise to?

Answer 7

it give rise to new differentiated tissues (protoderm)

Question 8

What is the function of shoot apical meristem?

Answer 8

it divides rapidly at the tip of the shoot, and it gives rise to new stems and leaves.

Question 9

What is the function of root apical meristem?

Answer 9

It divides rapidly at the tip of the root, and it elongate root.

Question 10

Three major types of plant tissue?

Answer 10

1. dermal tissue
2. ground tissue
3. vascular tissue.

Question 11

What are the three primary meristem in young leaves, stem, and roots?

Answer 11

1. protoderm
2. ground meristem
3. procambium

Question 12

What are the different parts of dermal tissue?

Answer 12

1. epidermis
2. Guard cell
3. leaf hair or trichome
4. periderm
5. root hair.

Question 13

what is epidermis?

Answer 13

It is a single layer cell that covers and protect young roots, stems, and leaves.

Question 14

where does the waxy cuticle get secreted from?

Answer 14

They get secreted from the epidermal cell.

Question 15

What is the function of guard cell?

Answer 15

They control stomata, they control gas exchange and water loss.

Question 16

Where is guard cells located?

Answer 16

They are found on the leaf and stem surfaces.

Question 17

What is the function of trichome?

Answer 17

It protects leaves.

Question 18

What is the function of periderm?

Answer 18

It is dead cork cells that replace living epidermis of stems; provide added protection.

Question 19

What is the function of root hair?

Answer 19

It provide root surface area for absorption.

Question 20

What are the three different part of ground tissue?

Answer 20

1. parenchyma
2. collenchyma
3. sclerenchyma

Question 21

What is parenchyma?

Answer 21

It is active cell with thin cell wall; it is photosynthetic mesophyll cell.

Question 22

What is the cortex?

Answer 22

It is a shallow stem tissue

Question 23

What does parenchyma contain of?

Answer 23

1. cortex
2. internal pith
3. mesophyll cell

Question 24

What is the function of parenchyma?

Answer 24

1. it store carbohydrate

2. photosynthetic cell

Question 25

What is collenchyma?

Answer 25

It is flexible cell with thick cell wall

Question 26

What is the function of collenchyma?

Answer 26

it provide flexible support in growing stem.

Question 27

What is sclerenchyma?

Answer 27

It is hard cell with thick cell wall

Question 28

What is the function of sclerenchyma?

Answer 28

They are dead cell when mature, so they provide rigid support to tissues 2. they form plant fibers and sclereids cells.

Question 29

What are the key characteristic of monocot leaf structure?

Answer 29

1. lack petiole 2. leaf morphology is knife like blade. 3. parallel venation.

Question 30

What are the key characteristic of eudicot leaf structure?

Answer 30

1. petiol exist 2. leaf morphology is broad-leafed 3. different type of venation (pinnate, and palmate)

Question 31

What are the different type of broad leaf eudicot?

Answer 31

1. simple leave | 2. compound leave

Question 32

What is the difference between simple leaf and compound leave in terms of structure and advantage?

Answer 32

1. simple leave: one petiole and single blade. They maximize surface area for shady environment 2. compound leave:one petiole and multiple leaflet. they foster heat dissipation in hot sunny environment.

Question 33

What are the different venation the eudicot leaves have?

Answer 33

1. pinnate (feather- like) | 2. palmate (multiple from common point.)

Question 34

What does the stem (non-woody) structure consists of?

Answer 34

1. epidermis 2. cortex 3. sclerenchyma 4. vesicle tissues.

Question 35

What makes up cortex?

Answer 35

it is composed of flexible collenchyma and parenchyma

Question 36

What is vascular cambium?

Answer 36

It is secondary meristem between xylem and phloem.

Question 37

What is the cork cambium?

Answer 37

It is a secondary meristem that that produces dead cork cell that form the periderm.
