Answer:
Phloem in gymnosperms lacks companion cells.
Explanation:
Companion cells are the cells with abaundent plasma and nucleus present in angiosperms.
But these cells are absent in gymnosperms.
Gymnosperms do not need root pressure to get water from soil as most of them are grown in cold and dry climates.
Hence gymnosperms lack companion cells.
Answer:
Phloem in gymnosperms needs buddy cells. Friend cells are the cells with abaundent plasma and core present in angiosperms. In any case, these cells are missing in gymnosperms. Gymnosperms needn't bother with root strain to get water from soil as the greater part of them are developed in cold and dry atmospheres.
Consequently gymnosperms need sidekick cells. Phloem is made out of a few cell types including sclerenchyma, parenchyma, strainer components and partner cells.
