Plant Systems Overview

The Vascular System of Plants

Stomata
Pores on the underside of the leaf that open and close to allow gases (Carbon Dioxide) to enter and exit (Oxygen) the leaf in order for photosynthesis to occur.

Multiple Choice

Stomata are made of specialized cells called ______ which surround a tiny pore/opening

• stoma

• guard cells

• dermal cells

• diffusion channels

Multiple Choice

The main function of stomata is to

• capture sunlight

• protect leaves from insects

• allow gases to move rapidly in/out of leaves

• release sugars into the atmosphere

Multiple Choice

What is the function of GUARD cells in plants?

• Allow gas exchange

• Control the opening & closing of the stomata

• Contain DNA

• Nucleus

Multiple Choice

What is the relationship between stomata and photosynthesis in plants?

• The stomata is dependent on photosynthesis.

• The stomata are reactants of photosynthesis.

• Photosynthesis is dependent on stomata.

• Photosynthesis is independent of stomata.

Multiple Choice

Which choice correctly shows the gases that enter and exit plants during photosynthesis?

• Enter: Oxygen
  Exit: Carbon dioxide
• Enter: Water vapor
  Exit: Glucose
• Enter: Carbon dioxide
  Exit: Oxygen
• Enter: Light
  Exit: Water vapor

Chloroplasts
Organelles inside leaf cells that conduct photosynthesis to make glucose for the plant.

Multiple Choice

In what organelle of plant cells does photosynthesis occur?

• mitochondria

• centrioles

• chloroplast

• ribosomes

Multiple Choice

___________________ is the process by which light energy from the sun is turned into carbohydrates (chemical energy).

• Cellular Respiration

• The Carbon Cycle

• Photosynthesis

• The Choloroplast

Multiple Choice

Which of the following is NOT needed for photosynthesis

• Water

• Oxygen gas

• Sunlight

• Carbon Dioxide

Roots
Absorb water, nutrients, and minerals from the soil

Anchor the plant into the soil

Multiple Choice

The two main functions of roots are to absorb water and minerals and to ______________ the plant.

• anchor
• gather sunshine for
• protect

Multiple Choice

What plant system is below ground?

• Roots system

• Shoots system

• none of them are below ground

• both roots and shoots system

Vascular System
Tube-shaped tissues called xylem and phloem that transport
water, sugars, and other substances up and down the plant.

Xylemtransports water and minerals up from the roots to the
rest of the plant.

“Xy to the sky”

Phloem transports sugars and amino acids, typically from the leaves down to the stems and roots.

“Phlo to the floor”

Multiple Choice

Vascular tissue that transports water and minerals UPWARDS from a plant's roots is know as ______.

• Chlorophyll
• Phloem
• Stomata
• Xylem

Multiple Choice

The plant tissue that carries food materials DOWNWARD from the leaves to the rest of the pant is the ______.

• Phloem
• Stomata
• Chlorophyll
• Xylem

Multiple Choice

True or False: Xylem transports water and minerals in both upward and downward directions.

• Xylem transports only minerals

• True

• False

• Xylem transports only water

Multiple Choice

True or False: Phloem transports substances only in upward direction.

• True

• False

• Phloem transports substances in both upward and downward directions.

• Phloem transports substances only in downward direction.

Multiple Choice

Which pair or definitions is correct?

• Xylem moves water up. Phloem moves food everywhere.

• Phloem moves water up. Xylem moves food everywhere.

• Xylem moves water down. Phloem moves food everywhere.

• Phloem moves water down. Xylem moves food everywhere.

Multiple Choice

Xylem and Phloem are both __.

• Transpiration

• Absorption

• Photosynthesis

• Vascular tissue
