The endoplasmic reticulum provides structure to the whole cell, or support, you could say.
The cell membrane protects the whole inside of the cell, and is the structure.

Answer:

Cell Wall, Plasma Membrane and Peroxisomes.

Explanation:

  1. In the case of plant eukaryotic cells, a cell wall formed by cellulose is the main structure responsible for provinding resistance and protection to cells, especially against dehydration.
  2. All eukaryotic cells also have a semipermeable plasma membrane composed of a double layer of phospholipids, with the function of controlling the entry and exit of molecules, protecting the internal content of the cell.
  3. Peroxisomes are cellular organelles responsible for producing the catalase enzyme, which transforms toxic oxygenated water molecules that are toxic to cells into non-toxic water and oxygen molecules. In other words, it protects cells against intoxication by byproducts resulting from cellular metabolism.

Why is bacteria placed in the kingdom prokaryotes
sukhopar [10]
Prokaryotes are chiefly defined as cells without a nucleus to contain the genetic information. Bacteria do not have a nucleus but, like prokaryotes, a nucleoid region in the center where the DNA can be found. Bacteria also do not have membrane-bound organelles, but they do have ribosomes to synthesize proteins. Bacteria vary a lot in the different structures they can have, but these basic factors make bacteria prokaryotes.

Vedmedyk [2.9K]

Answer:

Igneous rocks are the cooling and hardening of magma or lava and sedimentary rock is made of sediment cemented together

Explanation:

The three types of rock are igneous, metamorphic and sedimentary. Igneous rock is formed by the cooling and hardening of magma and lava. Examples include granite and basalt. Metamorphic rock is formed when other rocks are exposed to high heat and pressure, causing a chemical change in the rock. Examples include marble and gneiss. Sedimentary rock is formed when sediment is cemented together by minerals. Examples include sandstone and limestone.
