If a flowering plant has a diploid chromosome count of 8, then 4 chromosomes will be found in _________________?
Show answer Hide answer
Answer: D. Synergids
Explanation
Synergids are haploid cells within the female gametophyte, meaning they contain half the diploid chromosome count. If the plant has a diploid chromosome count of 8, the haploid number equals exactly 4. Female gametophyte cells like synergids and the egg cell maintain this reduced haploid chromosome complement. Diploid somatic cells contain two complete sets of chromosomes inherited from both parent plants. Haploid cells contain a single set of unpaired chromosomes generated through meiotic cell division. Plant reproductive tissues feature a mix of haploid gametophytic cells and diploid sporophytic maternal tissues.
Understanding plant gametophyte chromosome counts is essential for analyzing fertilization and embryogenesis. Plant cytologists study synergid cells to understand pollen tube guidance during double fertilization events. Genetics research relies on accurate chromosome tracking through various stages of the plant life cycle. Endosperm cells in angiosperms are triploid, meaning they would contain 12 chromosomes rather than 4. Leaf cells are somatic and diploid, retaining the full chromosome count of 8 rather than the haploid number. Cotyledonary cells are embryonic tissues that remain diploid, containing the full complement of 8 chromosomes.

Q4. If the haploid chromosome number of a gymnosperm species is 12, the chromosome complement within its nutritive endosperm tissue will be__________________?
Show answer Hide answer
Answer: B. 12
In gymnosperms, the nutritive endosperm is haploid tissue formed directly from the female gametophyte. Because the endosperm originates before fertilization in gymnosperms, its chromosome count matches the haploid number...
Q5. If the baseline haploid chromosome count in a plant is 12, the total chromosome number in a monosomic individual will be_________________?
