permanent tissue Flashcards
complex permanent tissue (phloem tissue)
how many types of phloem tissues are there in the phloem tissues
and what are they ?
4 types
sieve tube element
companion cells
phloem fibers
phloem parenchyma
how many living tissue are there in the phloem tissue
and what are they
3 living tissues
sieve tube element
companion cells
phloem parenchyma
what is the only non-living tissue in phloem tissue
phloem fibers
what is the function of sieve tube element
transportation of food (mainly sucrose)
in which type of phloem tissues, when transpotation of food mainly carries glucose then turns into sucrose
sieve tube element
what is the function of phloem tissue
the food synthesized in the leaves are transport thought the plant body by this tissue. (translocation)
which cells contribute to transport food thought out the plant
sieve tubes element
what is companion cells ?
Elongated cells associated with sieve tube element
what is the function of phloem fibers
Mechanical support
which type of phloem tissues as the function mechanical support
phloem fibers
‘controlling the activities in sieve tube’ in which type pf phloem tissue does this function
companion cells
what is the function of phloem parenchyma tissue
food and water storage
