Quiz Answer Key and Fun Facts

1. What sub-discipline of botany studies such processes as photosynthesis, respiration, tropisms, and mineral nutrition?

Answer: Plant physiology

Plant morphology studies the structure of plants, phytochemistry studies biochemistry of plants and plant molecular biology studies the important biological molecules of plants.

2. Where do the lateral roots originate?

Answer: Pericycle

Pericycle is located at the most outward of the root vascular cylinder and is considered a primary tissue.

3. In pollination, a flower undergoes a double fertilization. What is the product of a sperm and two haploid polar nuclei?

Answer: triploid endosperm

One cell produced by a pollen grain will generate two male gametes. One will meet with the egg nuclei producing a diploid zygote and the other will meet with the two haploid polar nuclei to produce a triploid endosperm.

4. What do you call the colorless plastids in plant cells that form and store starch, oils, and proteins?

Answer: Leucoplasts

Leucoplasts are found in the non-photosynthetic tissues of plants. They also take part in the synthesis of fatty and amino acids.

5. What do you call the complex tissue that forms the outer bark in woody plants?

Answer: Periderm

It is produced by cork cambium on the inside and cork cells towards the outside. It functions primarily as storage in woody stems.

6. These are sites of loosely arranged cells that allow for gas exchange. What are they?

Answer: Lenticles

The four options are external structures of the stem. Node is the area on the stem where leaf is attached, buds are undeveloped shoots, and leaf scar shows where each leaf is attached in the stem.

7. Which of the following factors does not affect the opening and closing of stomata?

Answer: direction of wind

Wind can be a factor that affects the rate of transpiration in plants.

8. Complete the equation given: ribulose phosphate (RP) + ____________ = ribulose bisphosphate (RuBP)

Answer: phosphate

Ribulose bisphosphate is a five-carbon sugar that takes part in the first stage of the light-independent reaction of photosynthesis. LIR depends on the products of the LDR (light-dependent reaction) and occurs in the stroma of chloroplasts.

9. What hormone in plant that functions as stem simulator delays senescence of leaves & citrus fruits, and can end seed dormancy in plants that require light for induction?

Answer: Gibberelin

Gibberelin also takes part in seed germination, and promotes flowering.

10. Which of these plant nutrients is not considered a macronutrient?

Answer: Iron

Macronutrients are nutrients that plants requires in fairly large quantities. These are Carbon, Hydrogen, Oxygen, Nitrogen, Phosphorus, Calcium, Magnesium, Sulfur, and Potassium.
