Q

► Plants are Earth’s Primary Producers
► Harvest Energy from sunlight by converting light energy into
chemical energy
► They store this chemical energy in bonds formed when they synthesize carbohydrates from carbon dioxide and water.
► Non-motile
► Have evolved to grow towards resources throughout their life span.

16
Q

PLANT TISSUE SYSTEM
- A dermal tissue that is usually a single layer of cells covering the younger parts of a plant. It secretes a waxy layer called the Cuticle that inhibits water loss.

A

EPIDERMIS

17
Q

PLANT TISSUE SYSTEM
- these tissues are involved in photosynthesis, storage, regeneration, support, and protection.
- the 3 types of ground tissue includes parenchyma, collenchyma, and sclerenchyma.

A

GROUND TISSUE

18
Q

PLANT TISSUE SYSTEM
- alive at maturity
- have thin cell walls and large vacuoles, and are most abundant of all the cells
- intercellular space is found
- they function in storages, photosynthesis, exchange of gases and as the bulk of ground and vascular tissues, store protein and starch, and for repair

A

PARENCHYMA

19
Q

PLANT TISSUE SYSTEM
- specialized for support for primary tissues
- cells are elongated, with walls (especially corners) thickened with pectin and cellulose
- no intercellular space
- makes stems strong but pliable
- cells are alive at maturity

-main function: to provide support for growing tissues, like stem.

A

COLLENCHYMA

20
Q

PLANT TISSUE SYSTEM
- supports mature plant parts
- protect many seeds
- cells have thickened lignified walls and are dead at maturity

  • main function: to provide support for the plant
  • 2 types: Fibers, Sclereids
A

SCLERENCHYMA

21
Q

PLANT TISSUE SYSTEM
- Long, tapered cells

A

FIBERS

22
Q

PLANT TISSUE SYSTEM
- Stubbier cells

A

SCLEREIDS

23
Q

PLANT TISSUE SYSTEM
- composed of xylem and phloem, which function in the transport of water and dissolved substances

  • function: transports material between the root and the shoot of the plant
A

VASCULAR TISSUE

24
Q

PLANT TISSUE SYSTEM
- Conducts water and dissolved minerals
- Conducting cells are dead and hollow at maturity

A

XYLEM

25
Q

PLANT TISSUE SYSTEM
- Transports sugar
- Main conducting cells are sieve-tube members
- Companion cells assists in the loading of sugars

A

PHLOEM

26
Q

PLANT TISSUE SYSTEM
- Covers and protects plant surfaces
- Secretes a waxy, waterproof cuticle
- Plants with secondary growth, periderm replaces epidermis

A

EPIDERMIS

27
Q

have different stem and root anatomies

A

DICOTS and MONOCOTS
