The cell membrane is said to be selectively permeable is because it allows a select few things to go through while stopping the passage of other stuff.
This statement is mostly false. While all organisms do share basic needs to sustain life, there is a wide variety of strategies employed to meet these needs. For example, while most plants receive nutrients from soil, some live in soils which do not fully meet their needs. Such plants sometimes kill and use animals in order to meet these needs (i.e. venus flytrap) or partner with bacteria that produce some of the nutrients they need (i.e legumes).
B because the peptides when they collect in a clump, has a effect like hydrocloric acid.

Endoplasmic reticulum is situated close to the nucleus and is involved
in protein synthesis. Rough ER has lysosomes around the edges.
Lysosomes - The cleaner of the cell. Small and numerous, increases
surface area and increases the rate at which waste products are removed
from the cell.
Chloroplasts - Made up of Grana, stacked up to increase surface area.
This allows more Chlorophyll to be made to increase the rate of
photosynthesis.
Nucleus - Information point of the cell</span>
