NEET BIOLOGY

Detailed explanation-1: -All eucaryotic cells have an endoplasmic reticulum (ER).

Detailed explanation-2: -Plasma membrane-controls what enters and leaves the cell (also present in eukaryotic cells) Ribosomes-the site of protein synthesis, (70s)

Detailed explanation-3: -The outer lining of a eukaryotic cell is called the plasma membrane. This membrane serves to separate and protect a cell from its surrounding environment and is made mostly from a double layer of proteins and lipids, fat-like molecules.

Detailed explanation-4: -Plant cells have a cell wall, a large central vacuole, and plastids such as chloroplasts. The cell wall is a rigid layer that is found outside the cell membrane and surrounds the cell, providing structural support and protection. The central vacuole maintains turgor pressure against the cell wall.

Detailed explanation-5: -Cell membranes protect and organize cells. All cells have an outer plasma membrane that regulates not only what enters the cell, but also how much of any given substance comes in.
