Which organelle can be compared to a security guard who decides whom may enter a building and whom may not? cell membrane cytoplasm endoplasmic reticulum mitochondrion

The correct answer would be the cell membrane.

The plasma membrane or cell membrane is a semi-permeable membrane which forms the outer covering of the cell.

This membrane is made up of a phospholipid which provides it with its semi-permeable nature.

Due to its semi-permeable nature, it controls the movement of substances inside and outside the cell.

1: most common garden plants prefer loam — soils with a balance of different-sized mineral particles (approximately 40% sand, 40% silt, and 20% clay) with ample organic matter and pore space. however, some plants grow better in sandy soils, while others are well-adapted to clay soils.

2: available water capacity is the maximum amount of plant available water a soil can provide. it is an indicator of a soil's ability to retain water and make it sufficiently available for plant use. available water capacity is the water held in soil between its field capacity and permanent wilting point.

3: it is the same for all living things (plants and animals). it also includes very tiny organisms that our eyes cannot see. they are known as microorganisms, and include viruses, bacteria and fungi.
