Prokaryotic Cells: Lack a membrane-bound nucleus and membrane-bound organelles. whille Eukaryotic Have a membrane-bound nucleus that separates the genetic material (DNA) from the cytoplasm.
What is differences between prokaryotic and eukaryotic cells? Read More »
It contain enzymes capable of breaking down cellular components and waste materials and also save the cell from damage.
Proteins are synthesized inside the cell at structures called ribosomes. These ribosomes can be found free-floating in the cytoplasm or attached to the endoplasmic reticulum, another organelle.
Prokaryotic Cells: Simpler, smaller, lack nucleus and organelles. DNA in nucleoid. Examples: Bacteria, Archaea. Eukaryotic Cells: Complex, larger, have nucleus and organelles. DNA in nucleus. Examples: Animals, plants, fungi, protists.
Mitochondria are called the powerhouse because they are responsible for cellular respiration. They take in glucose and oxygen and produce energy (ATP) that fuels all cellular activities
Which organelle is known as the powerhouse of the cell? Why? Read More »
Lipids: These are synthesized in the smooth endoplasmic reticulum (SER). and Proteins are made by ribosomes
Where do the lipids and proteins constituting the cell membrane get synthesised? Read More »
Amoeba, a single-celled organism, engulfs its food through a process called phagocytosis. It extends finger-like projections of its cell membrane to surround a food particle (bacteria, another small organism).
Mitosis for growth and repair of body. Meiosis for gamete formation. Mitosis yields two identical daughter cells; meiosis produces four non-identical daughter cells.
(i) Water gathers in cups B and C due to osmosis caused by sugar and salt, respectively. (ii) Potato A serves as a control to compare changes observed in other cups. (iii) Water doesn’t gather in cups A and D because there’s no solute to create a concentration gradient.
Golgi apparatus is like a cellular packaging and distribution center. If it’s missing, proteins, lipids, and other molecules wouldn’t be properly modified, sorted, and transported within the cell or secreted outside. This would disrupt various functions, likely leading to cell death.
What would happen to the life of a cell if there was no Golgi apparatus? Read More »
A rupture disrupts this control, leading to uncontrolled movement of molecules and ions, causing the cell to swell and burst, ultimately resulting in cell death
What would happen if the plasma membrane ruptures or breaks down? Read More »
Prokaryotic cells lack a true nucleus and membrane-bound organelles, containing circular DNA. They are smaller and include bacteria and archaea. Eukaryotic cells have a true nucleus, membrane-bound organelles, and linear DNA. They are larger and include animals, plants, and fungi.
