Plant tissue systems_completed

Two main tissue types of plants:

• Vascular and ground tissues

• Meristametic and permanent tissues

• Dividing and storage tissues

• Assimilatory and ground tissues

Each cell of the dermal tissue system

• does not contain chloroplasts except for the guard cells of the stomata.

• has not got a cell wall.

• contains chloroplasts except for the guard cells of the stomata.

• has the same bean-shape.

Guard cells of stomata work to control enormous _________loss closing on hot, dry, or windy days and opening when conditions are more favourable for gas exchange.

Stomata have bean-shaped guard cells with a. ------- outer wall, b.-------- inner wall

• a. thin b. thick

• a. thick b. thin

• a. flexible b. cellulose

The functions of stomata are

• supprt the plant and absorb water via osmosis.

• store starch grains and keep water.

• photosynthesis and respiration.

• transpiration and gas-exchange.

Assimilatory ground tissue cells contain

• glycogen.

• stomata.

• lots of chloroplasts..

• cellulose.

Vascular tissue consists of

• silem and cloem.

• xylem and phloem

• xilem and ploem.

• xylim and phloim.

Xylem is primarily concerned with a.____________ and phloem with

b. _______________.

• a. organic matter transport. b. water and ion transport

• a. transportation of the nutrition b. absorption of water

• a. respiratory gas exchange b. excretion in the form of starch.

• a. water and ion transport b. organic matter transport.

Vascular tissue elements, the xylem and the phloem form

• vascular bundles.

• vascular vessels.

• a stem.

• plants.

Phloem contains living cells.

• True.

• False.
