What is the function of dermal tissue?

A

protect and prevent water loss

25
Q

What is ground tissue?

normal plant tissue (not vascular and not dermal)

26
Q

What are the 3 cell components that make up ground tissue?

A
  1. parenchyma
  2. collenchyma
  3. sclerenchyma
27
Q

What is the job of parenchyma?

Is parenchyma alive at maturity?

A

yes

29
Q

Where would you find parenchyma cells?

A

in leaves

30
Q

What is the job of collenchyma cells?

A

to provide flexible support

31

Where would you find collenchyma cells?

A

in celery

32
Q

Are collenchyma cells alive at maturity?

A

yes

33
Q

What is the job of sclerenchyma cells?

A

to provide rigid support because of lignin

34
Q

Where would you find sclerenchyma cells?

A

nutshells and skin of fruits

35
Q

Are sclerenchyma cells alive at maturity?

A

no

36
Q

What are the components of vascular tissue?

A
  1. xylem
  2. phloem
37
Q

What is the function of vascular tissue?

A

transport water and sugar

38
Q

What does the xylem do?

A

move water up a plant

39
Q

What does phloem do?

A

move sugar and other nutrients up and down the plant

40
Q

What are the two types of xylem?

A

vessels and tracheids

41
Q

Are vessels and tracheids dead or alive at maturity?

A

dead

42
Q

What are sieve tubes?

A

part of the phloem that helps the transportation of nutrients

43
Q

What is the function of roots?

A

absorption of nutrients and anchoring

44
Q

Where is the root epidermis located?

A

outside the root (with the root hairs)

45
Q

What is the root cortex?

A

inside the epidermis and it holds the ground tissues

46
Q

What is the endodermis?

A

inside the cortex, has suberin

47
Q

Why does the endodermis have suberin and where is it located?

A

it is located between the casperian strip, it helps filter water and nutrients into the plant

48
Q

What is the function of the root pericycle?

A

gives rise to branch roots

49
Q

What does ephemeral mean?

A

plants that live and die in weeks

50
Q

What does perennial mean?

A

plants that growth year after year

51
Q

What does annual mean?

A

plants that live for a year

52
Q

What does biennial mean?

A

plants that live for 2 years

53
Q

What do biennial plants do the first year?

A

grow and store carbs

54
Q

What do biennial plants do their second year?

A

use stored energy to reproduce

55
Q

Is phloem part of bark?

A

yes
