Question

Chloroplast is domed shape because

A) They are more efficient in absorbing light energy while dome

B) Being domed shape allows chloroplast to increase oxygen production

C) Domed shape chloroplast splits sunlight into its component wavelength as not all spectrum participates in photosynthesis

D) Domed shape chloroplast allows the chlorophyll to adsorbed more light energy

What will happen if you grow your yucca in the dark for 2wks while providing nutrient, water and CO2?

A) Nothing….I will have nice yucca yam at end of 2wks

B) The leaves will be dull or dead so no yucca yam will be available at the end of 2wks

C) The yucca yam will be bigger than if I grew it outside; after all carbohydrates are made in night reaction.

D) The yucca yam will not form at all for it needs light to make ATP to drive yucca production at night

Leaves in plants act like solar panel to harness the sun’s energy and for cellular respiration

A) Absolutely true statement

B) Absolutely false statement

C) There is some truth to the statement and I can prove that

Answer 1

1. D) Domed shape chloroplast allows the chlorophyll to adsorbed more light energy

This shape of chloroplast together with their alignment along the inner surface of the cell maximizes their ability to capture light.

2. D) The yucca yam will not form at all for it needs light to make ATP to drive yucca production at night

Light is very necessary for photosynthesis as light provides energy in the form of ATP to carry out dark reactions for the formation of glucose.

3. a true statement

Photosynthesis and respiration are the reverse processes occurring in leaves. The process of respiration in plants involves using the sugars produced during photosynthesis plus oxygen to produce energy for plant growth. In many ways, respiration is the opposite of photosynthesis.
