sieve tube उदाहरण वाक्य

उदाहरण वाक्य

1. Organic molecules such as sugars, amino acids, certain hormones, and even messenger RNAs are transported in the phloem through sieve tube elements.
2. The ends of these cells are connected with other sieve tube members, and together they constitute the "'sieve tube " '.
3. The ends of these cells are connected with other sieve tube members, and together they constitute the "'sieve tube " '.
4. Each sieve tube element is normally associated with one or more nucleated companion cells, to which they are connected by plasmodesmata ( channels between the cells ).
5. The pathogen, sandal spike phytoplasma, was first detected by pleomorphic and fragile organisms occupying relatively small areas within the sieve tubes ( phloem ) of the host plants.
6. Sieve tubes are joined end-to-end with perforate end-plates between known as " sieve plates ", which allow transport of photosynthate between the sieve elements.
7. The main function of the sieve tube is transport of carbohydrates, primarily sucrose, in the plant ( e . g ., from the leaves to the fruits and roots ).
8. At the interface between two sieve tube members in angiosperms are "'sieve plates "', pores in the plant cell walls that facilitate transport of materials between them.
9. Sieve tube members have no cell nucleus, ribosomes, or leaves, companion cells help move the sugar that is produced by photosynthesis from the mesophyll tissue into the sieve tube elements.
