What role does lignin play in a plant's adaptation to life on land? what role does lignin play in a plant's adaptation to life on land? transports nutrients throughout the plant prevents drying out strengthens the cell wall to allow plants to stand up straight and tall anchors the plant in the soil to allow plants to grow tall?

The answer is B. Strengthens the cell wall to allow plants to stand up straight and tall

Lignin is a polymer that constitutes the cell walls of all vascular plants. It provides the mechanical support for plants and it supplies the strength and rigidity of plant cell walls. Structural strength provided by lignin helps large trees to reach heights in excess of 100 m. In the absence of lignin these trees would collapse on themselves.

answer: i don't know

explanation:

you need to provide a picture, otherwise i can't tell you.

if you can provide one, i'd be more than happy to you with this!

the corpus luteum secretes estrogens and progesterone. the latter hormone causes changes in the uterus that make it more suitable for implantation of the fertilized ovum and the nourishment of the embryo. if the egg is not fertilized, the corpus luteum becomes inactive after 10–14 days, and menstruation occurs.

i hope this : )
