Plant Biology Quiz

What is cytoplasmic streaming?

• The movement of chloroplasts within a cell

• The release of energy to fuel cell activities

• The process of water loss through leaves

• The transport of nutrients in the plant stem

Write the word and chemical equations for cellular respiration.

• C6H12O6 + 6O2 → 6CO2 + 6H2O + Energy

• 6CO2 + 6H2O → C6H12O6 + 6O2

• C6H12O6 + 6O2 → 6CO2 + 6H2O

• 6CO2 + 6H2O + Energy → C6H12O6 + 6O2

What does photosynthesis mean?

• Breaking down glucose to produce energy

• Converting light energy into chemical energy

• Releasing oxygen into the atmosphere

• Absorbing carbon dioxide from the air

How does diffusion occur on the stem of birch trees?

• Through lenticels

• Through stomata

• Through guard cells

• Through palisade cells

How are chloroplasts easily identifiable?

• They are long and narrow

• They contain green pigment chlorophyll

• They are round and loosely packed

• They are transparent

What is the purpose of xylem tissue and phloem tissue?

• Transporting water and minerals

• Producing hormones

• Carrying out photosynthesis

• Providing structural support

Why are xylem and phloem cells important to the survival of the plant?

• They provide structural support

• They regulate gas exchange

• They transport water and nutrients

• They produce energy for the plant

What terms are used for where sugars are manufactured and where they are used or stored?

• Xylem and phloem

• Source and sink

• Palisade and spongy cells

• Epidermal and guard cells

Describe the mechanism by which the sugars are moved from the leaves to the rest of the plant.

• Diffusion through stomata

• Transpiration pull

• Phloem transport

• Active transport

What are the sugars used for when they are passed on to the rest of the plant?
