Q: Which equation represents the balance shift in embryonic root development?

$$\text{Basal cell} \rightarrow \text{Embryonic root structures}$$

Question 1

During plant fertilization, the first mitotic division produces two distinct cells. Which of the following best describes their roles?

Accepted Answer

The apical cell forms the embryo, while the basal cell forms the suspensor.

Question 2

Which hormone is produced by the basal cell and sent to the apical cell during early plant embryogenesis?

Accepted Answer

Auxin

Question 3

In plant morphogenesis, oriented cell division increases length along the root-shoot axis. Which plane do cells divide on to achieve this?

Accepted Answer

Transverse plane

Question 4

Which of the following statements about meristem is correct?

Accepted Answer

Mitosis only occurs in the meristem.

Question 5

Homeotic genes regulate flower development. Which gene class is specifically important for differentiating petals from sepals and carpels from stamens?

Accepted Answer

B gene class

Question 6

In the normal arrangement of floral organs in Arabidopsis thaliana, which whorl contains the stamens?

Accepted Answer

Whorl 3

Question 7

Which process describes the transformation of one body part into another due to genetic regulation?

Accepted Answer

Homeosis

Question 8

Cells at the tip of a developing leaf are the oldest. What is the significance of this in terms of photosynthesis?

Accepted Answer

They are the first cells capable of photosynthesis.

Question 9

Pattern formation in plant development ensures proper organization of cells. Which tissues are formed as a result?

Accepted Answer

Vascular, ground, and epidermal tissue

Question 10

Environmental cues play a role in plant development. Which of the following best describes their effect?

Accepted Answer

They regulate gene expression and hormone production, affecting differentiation.

Question 11

A mutation in the B gene class of a flower results in the absence of petals and stamens. Which whorls would be affected?

Accepted Answer

Whorl 2 and Whorl 3

Question 12

Which equation best represents the process of mitosis in plant cells?

Accepted Answer

$$	ext{Parent cell} ightarrow 2 	ext{daughter cells}$$

Question 13

Which of the following is NOT a characteristic of plant morphogenesis?

Accepted Answer

Cell and tissue migration

Question 14

If a plant's basal cell fails to produce auxin, what is the most likely outcome?

Accepted Answer

The apical cell will not develop properly into the embryo.

Question 15

Which of the following best describes the role of sieve tube members in leaf development?

Accepted Answer

They immediately penetrate new primordia, aiding early nutrient transport.

Question 16

Which equation represents the balance shift in embryonic root development?

Accepted Answer

$$	ext{Basal cell} ightarrow 	ext{Embryonic root structures}$$

Question 17

Which of the following is true about the oldest cells in a developing leaf?

Accepted Answer

They are located at the leaf tip.

Question 18

Which of the following best describes the process of pattern formation in plants?

Accepted Answer

Ensures proper organization of cells along the root-shoot axis.

Question 19

Which of the following is a real-world application of understanding homeotic gene function in plants?

Accepted Answer

Engineering flowers with altered organ arrangements for ornamental purposes.

Question 20

Which equation best represents the relationship between environmental cues and hormone production in plant development?

Accepted Answer

$$	ext{Environmental cues} ightarrow 	ext{Gene-regulated hormone production}$$
