Question 1

Compared with sun leaves, shade leaves:

Accepted Answer

Shade leaves have adapted to receive less light than sun leaves and therefore have a lower ratio of mesophyll surface area (where photosynthesis occurs) to leaf blade surface area. This allows them to make the most of the limited light they receive. The other options are not necessarily true of all shade leaves and may depend on the specific species and environment.

Question 10

In eudicots, the major veins develop toward the ______ and the minor veins develop toward the ______.

Accepted Answer

In eudicots, the major veins develop toward the leaf margins and the minor veins develop toward the leaf base.

Accepted Answer

The answer of Unlike the midrib, the leaf blade develops...

Question 12

In leaves, intercalary growth occurs by:

Accepted Answer

Intercalary growth in leaves occurs through both cell division and cell enlargement throughout the blade. This allows for the elongation of the leaf blade over time.

Question 13

Studies of Arabidopsis mutants have identified classes of ______ that affect the identity of floral organs.

Accepted Answer

Arabidopsis mutants have been studied extensively and have revealed several classes of homeotic genes that regulate the identity of floral organs. These genes are responsible for determining which type of floral organ develops in each region of the flower, such as sepals, petals, stamens, and carpels. Mutations in these genes can lead to abnormal development of floral organs or the formation of organs in the wrong regions, providing important insights into the genetic control of flower development.

Question 14

Unlike C₃ grasses, C₄ grasses have leaves:

Accepted Answer

The answer of Unlike C₃ grasses, C₄ grasses have leaves: ...

Question 15

The studies of homeotic mutations in Arabidopsis initially identified _____ classes of genes essential to normal flower development, but this model has recently been expanded to ____ gene classes.

Accepted Answer

The studies of homeotic mutations in Arabidopsis identified 3 classes of genes essential to normal flower development: A, B, and C. However, the model has been expanded to 5 gene classes with the addition of D and E genes.

Question 16

In grass leaves, the midvein and other large longitudinal strands arise at the _____ of the primordium and develop _____.

Accepted Answer

According to the statement, the midvein and other large longitudinal strands arise at the base of the primordium and develop both upward and downward. Thus, option C is the correct answer.

Question 17

Most tendrils are modified:

Accepted Answer

The answer of Most tendrils are modified:
...

Question 18

The homeotic mutation that results in "double flowers" in some rose varieties causes ______ to be converted into ______.

Accepted Answer

The answer of The homeotic mutation that results in "double...

Question 19

Unlike the leaves of eudicots, most monocot leaves:

Accepted Answer

Most monocot leaves have parallel venation, meaning the veins run parallel to each other from the base of the leaf to the tip. This is in contrast to eudicot leaves, which typically have netted venation with branching veins.

Question 20

A spine is a modified:

Accepted Answer

The answer of A spine is a modified:
...
