Biology Unit 4 Study Guide: Energy

The differences between two molecules include the type of sugar that forms a section of the molecules and the identity of the four nitrogenous bases that make up another section of the molecules. These two molecules are--

• Proteins

• Lipids

• Nucleic Acids

• Complex Carbohydrates

Which of the following biomolecules contains nitrogen AND phosphate?

• Lipid

• Protein

• Nucleic Acid

• Carbohydrate

Carbohydrates are more easily digested then lipids. However, on a gram-for-gram basis, lipids provide cells with more--

• Nitrogen

• Proteins

• Structure

• Energy

Location inside of a plant cell where the process of photosynthesis occurs.

• nodules

• stomata

• chloroplasts

• chlorophyll

Pigment which 'fills' chloroplast. This pigment absorbs sunlight.

• nodules

• stomata

• chlorine

• chlorophyll

These open up to collect sunlight and contain the chloroplasts which produce food.

• roots

• leaves

• flowers

• tree bark

A reactant in Photosynthesis

• PB

• NACL

• H20

• CO2

A product for photosynthesis

• CO2

• O2

• H2O

• heat

The process of photosynthesis takes place in the:

• Leaves of the Plant.

• Stem of the plant.

• Roots of the plant.

• All of the above.

What are the 3 key ingredients needed for photosynthesis

• glucose, oxygen, carbon dioxide
• carbon dioxide, water, glucose
• water, soil, sunlight
• sunlight, water, carbon dioxide
