How many of the given cells do not possess nucleus? Companion cells, ...
Cells without nucleus in the given options:
- Companion cells
- Albuminous cells
- Mature sieve tube
Explanation:
Companion cells: Companion cells are specialized parenchyma cells found in the phloem of flowering plants. They are closely associated with sieve tube elements and provide metabolic support to the sieve tube elements. Companion cells possess a nucleus, as they are metabolically active and play a crucial role in the functioning of the phloem.
Albuminous cells: Albuminous cells are storage cells found in the seeds of gymnosperms. These cells contain reserve food material and do not possess a nucleus. The loss of the nucleus allows for more efficient storage of nutrients in these cells.
Mature sieve tube: Mature sieve tubes are specialized cells found in the phloem of plants. They are responsible for the transport of organic nutrients throughout the plant. Mature sieve tubes lack a nucleus, as they undergo a process called enucleation during their development to create more space for the flow of nutrients.
Therefore, out of the given options, three cells do not possess a nucleus: Companion cells, Albuminous cells, and Mature sieve tube. The other cells mentioned, such as xylary fibres, sclereids, and phloem parenchyma, do possess a nucleus as they are metabolically active and involved in various physiological processes within the plant.
