Unit 10 - Plant Systems

What plant system makes sure the plant has enough water?

• Immune System

• Dermal System

• Reproductive System

• Vascular System

Answer explanation

The xylem transports water to the whole plant

Boron is a chemical that is important for plant reproduction. Based on this information, it can be assumed that boron is absorbed by the roots and then-

• transported to the reproductive tissues by the xylem

• stored in the plant's stem until the flowers are pollinated

• transported by the phloem to the leaves

Answer explanation

Xylem is the vascular system that transports from roots to leaves

Why do grass tips bend towards light?

• Water evaporates on the side closest to the light

• Light sensors stimulate the hormones in the shoot system

• The side facing the light absorbs more CO2

Answer explanation

Auxin is the hormone that is stimulated by the light sensors

Oh no! A bug chewed through the roots of a plant and now it cannot absorb water. If the plant cannot absorb water, what process will be affected?

• Seed dispersal

• Disease resistance

• Photosynthesis

What system transports food/water to the rest of the plant?

• Vascular system

• Dermal system

• Reproductive system

• None of the above
