Which tissue acts as a filter on the water absorbed by root hairs? View Available Hint(s) Which tissue acts as a filter on the water absorbed by root hairs? Epidermis Vascular tissue Endodermis Cortex

Endodermis

Explanation:

The roots in the plant absorb the water and nutrients from the soil by the process of osmosis.  The water and nutrients flow with the water through the apoplast and symplast way.

Before the entry of the water into the vascular bundles, few nutrients and other molecules are filtered by the selective diffusion mechanism of a layer of cells called the endodermis.

The endodermal cells possess the suberin deposition around the cell wall which permeates only symplast mode of transport and thus the selective passage of molecules.

Thus, Endodermis is correct.

the level of progesterone is low at the pre-ovulatory phase of the cycle but it gradually increases and the levels are high at the luteal phase. if pregnancy occurs, the level of progesterone will be high throughout the pregnancy.

if egg is fertilized and the mother gets pregnant, progesterone starts preparing the uterus for the implantation. it starts building up the lining of uterus and make it hostile of the period of pregnancy.
