seed coat protects the cotyledons and embryo from outer environment and from attack of pathogens

pollen grain has a sculptors covering with weak points(germ pores) in it through which pollen tube comes out.

A spore is generally protected by 2-3 tough resistant walls around to tied over the unfavourable conditions.

Proteins that are embedded within, and extend across, the phospholipid bilayer are called _____ proteins. rev: 02_22_2014_qc_455
brilliants [131]

Proteins that are embedded within, and extend across, the phospholipid bilayer are called <u>Integral Protein</u>.

Integral Protein- Any protein containing a unique functional area for the purpose of ensuring its location within the cellular membrane is referred to as an integral protein, which is also referred to as an integral membrane protein. Or, to put it another way, an integral protein seizes the cellular membrane.

Cellular membrane- All cells have a cell membrane, also known as a plasma membrane, which divides the inside of the cell from the external environment. A semipermeable lipid bilayer makes up the cell membrane. The movement of materials into and out of the cell is controlled by the cell membrane.

1. A normal mammalian cell will shrink if it is placed into_________. (Assume all solutes are non-penetrating) A. pure water B.
GrogVix [38]

Answer:

B. 50 mM glucose; E. 300 mM glucose

Explanation:

In order for the cell to shrink the concentration of solutes in the blood should be above normal or higher than the intracellular concentration, so that water moves from the inside of the cell to the outside by the process known as osmosis.

The normal blood levels of NaCl = ~ 154 mM; therefore A, C and D will not cause any shrinkage.

The normal blood levels of glucose = ~ 3.9 to 7.1 mM; therefore water would move from the intracellular to the extracellular space since the solutes are 10x higher outside the cell, causing shrinkage of the cell.
