Q

Why are stems improtant?

A

Brings water and nutrients to the leaves and carries food back to the roots. They also support the plant.

Q

Why are leaves improtant?

A

Essential for using the sun’s energy to make sugar from CO2 and water in the process of photosynthesis
Allows water ti evaporate–> transpiration

22
Q

Two types of Meristem Tissues

A

Apical Meristems

Lateral Meristems

23
Q

Apical Meristems

A
  • causes primary growth, ie. widening of plant

  • produces new leaves and flowers
24
Q

Lateral Meristems

A
  • causes secondary growth
  • occurs at the cambium

Fibrous

A
  • many small, branching roots

- ie. grass

41
Q

Transpiration

A

Movement of water from roots to leaves through xylem in veins

42
