Q

What is the function of shoot apical meristem?

A

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

16
Q

Where is guard cells located?

A

They are found on the leaf and stem surfaces.

17
Q

What is the function of trichome?

A

It protects leaves.

18
Q

What is the function of periderm?

A

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

19
Q

What is the function of root hair?

A

It provide root surface area for absorption.

20
Q

What are the three different part of ground tissue?

A
  1. parenchyma
  2. collenchyma
  3. sclerenchyma
21
Q

What is parenchyma?

A

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

22
Q

What is the cortex?

A

It is a shallow stem tissue

23
Q

What does parenchyma contain of?

A
  1. cortex
  2. internal pith
  3. mesophyll cell
24
Q

What is the function of parenchyma?

A
  1. it store carbohydrate

2. photosynthetic cell

25
Q

What is collenchyma?

A

It is flexible cell with thick cell wall

26
Q

What is the function of collenchyma?

A

it provide flexible support in growing stem.

27
Q

What is sclerenchyma?

A

It is hard cell with thick cell wall

28
Q

What is the function of sclerenchyma?

A

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

29
Q

What are the key characteristic of monocot leaf structure?

A
  1. lack petiole
  2. leaf morphology is knife like blade.
  3. parallel venation.
30
Q

What are the key characteristic of eudicot leaf structure?

A
  1. petiol exist
  2. leaf morphology is broad-leafed
  3. different type of venation (pinnate, and palmate)
31
Q

What are the different type of broad leaf eudicot?

A
  1. simple leave

2. compound leave

32
Q

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

A
  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.
33
Q

What are the different venation the eudicot leaves have?

A
  1. pinnate (feather- like)

2. palmate (multiple from common point.)

34
Q

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

A
  1. epidermis
  2. cortex
  3. sclerenchyma
  4. vesicle tissues.
35
Q

What makes up cortex?

A

it is composed of flexible collenchyma and parenchyma

36
Q

What is vascular cambium?

A

It is secondary meristem between xylem and phloem.

37
Q

What is the cork cambium?

A

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

38
Q

What are the different type of roots?

A
  1. taproot
  2. fibrous root
  3. adventitious root
