Round 1

1. 1. The MMC is the first cell in the female germline lineage to commit to which type of division?

• Mitosis

• Karyokinesis

• Meiosis

• Binary fission

2. Which of the following is nicknamed the “security guard” of the megaspore mother cell (MMC)?

• Funiculus

• Raphe

• Micropyle

• Callose

3. Which layer of the ovule corresponds to the innermost cell layer?

• Outer integument

• Inner integument

• Nucellus

• Embryo sac

4. In most angiosperm ovules, the micropyle gets displaced near the base of the funiculus during development because:

• The ovule curves

• The ovule straightens

• The nucleus shrinks

• Integuments fuse early

5. What is the visible ridge in a mature seed formed when the funiculus is fused with the nucellus called?

• Chalaza

• Raphe

• Micropylar ridge

• Vascular strand

6. In amphistomal type of micropyle, the micropyle is delimited by:

• Inner integument

• Outer integument

• Both

• Funiculus

7. Which of the following cell types are found at the chalazal pole?

• Synergids

• Antipodals

• Egg cell

• Polar nuclei

8. 8. Which type of nucellus lacks a parietal cell?

• Tenuinucellate

• Pseudocrassinucellate

• Both

• None

9. 9. How many nuclei are present in the mature gametophyte of the Oenothera type?

• 3

• 6

• 2

• 4

10. 10. Pseudocrassinucellate nucellus arises due to:

• Anticlinal divisions

• No divisions at all

• Fusion of nucellar cells

• Periclinal divisions
