1
Q

What are the two types of plant tissues?

A
  • Meristematic

- Permanent

2
Q

Characteristics of meristematic tissues:

A
  • Always dividing by mitosis.
  • Apical cells found at the tips of stems + roots.
  • Lateral meristems found at the sides of stems + roots.
3
Q

Characteristics of permanent tissues.

A
  • Do not actively divide.
  • Specialized cells.
  • Perform specific functions.
  • Found throughout the plant.
4
Q

Give three examples of simple permanent plant tissues.

A
  • Collenchyma
  • Parenchyma
  • Sclerenchyma
5
Q

Give three example of complex permanent plant tissues.

A
  • Epidermis
  • Phloem
  • Xylem
6
Q

What is the function of the Parenchyma?

A
  • Store food + water.

- Intercellular spaces allow gases + water to pass through.

7
Q

What is the function of the Sclerenchyma?

A
  • To provide mechanical/strength support. (in older stems + leaves)
  • Collenchyma is the opposite.
8
Q

What is the function of epidermal tissue?

A
  • Protect inner tissues.

- Cuticle prevents water loss. (by evaporation and protect against infection by pathogens)

9
Q

What is the function of the Stomata?

A
  • To let oxygen + carbon dioxide enter and exit the plant on leaves.
  • Lenticels for oxygen + carbon dioxide to enter and exit on stems.

Q

What is the function of the epidermal roots? (epidermal cell)

A

-The root hairs increase surface area to improve water absorption from the soil.
