Why is the mitochondria a bad organelle?
Because mitochondria are essential to so many cellular processes, when anything goes wrong with these organelles, they could be linked to many diseases. Recent discoveries have connected malfunctioning mitochondria to Parkinson’s, heart disease, diabetes, and cancer.
What is the most important organelle in a plant?
The Nucleus is the most important organelle in the plant cells.
What organelle is the least important?
The ribosome may be the smallest organelle in the cell, but it plays an important part. The ribosomes are vital to the cell; they make proteins for the cell to survive. Without the nucleus making the ribosomes, the cell would die.
What is the most useless cell organelle?
cell wall
What are the two most important organelles?
Organelle Among the more important cell organelles are the nuclei, which store genetic information; mitochondria, which produce chemical energy; and ribosomes, which assemble proteins.
What is the most abundant organelle?
Protein Factories Ribosomes Smallest but most abundant organelles Their job is to hook together amino acids to make proteins Found in both eukaryotic and prokaryotic cells Not covered by a membrane All cells have ribosomes because all cells need protein to live. 12.
Which cell is more abundant?
water
Where are ribosomes found?
Ribosomes are found ‘free’ in the cytoplasm or bound to the endoplasmic reticulum (ER) to form rough ER. In a mammalian cell there can be as many as 10 million ribosomes. Several ribosomes can be attached to the same mRNA strand, this structure is called a polysome. Ribosomes have only a temporary existence.
What are the most abundant organelles in a cell where do they occur?
So, the correct answer is ‘Ribosomes’.
What is the appearance of Golgi apparatus?
The Golgi apparatus (GA), also called Golgi body or Golgi complex and found universally in both plant and animal cells, is typically comprised of a series of five to eight cup-shaped, membrane-covered sacs called cisternae that look something like a stack of deflated balloons.
Which organelle is outside the plasma membrane?
Mitochondria and chloroplasts are also surrounded by membranes, but they have unusual membrane structures — specifically, each of these organelles has two surrounding membranes instead of just one. The outer membrane of mitochondria and chloroplasts has pores that allow small molecules to pass easily.
Is the plasma membrane an organelle?
The plasma membrane is the organelle that encapsulates the contents of the cell. Apart from encapsulating cell contents, the plasma membrane also plays a vital role in regulating the movement of substances in and out of the cell. The plasma membrane is made up of two layers of phospholipids (phospholipids bilayer).
What organelle makes proteins?
ribosomes
Do plant cells have a plasma membrane?
Plant cells resemble other eukaryotic cells in many ways. For example, they are enclosed by a plasma membrane and have a nucleus and other membrane-bound organelles.
Why do plant cells have chloroplasts and animals don t?
Both plant and animal cells are eukaryotic, so they contain membrane-bound organelles like the nucleus and mitochondria. For example, plant cells contain chloroplasts since they need to perform photosynthesis, but animal cells do not.
What are the similarities between plant cell and animal cell?
Structurally, plant and animal cells are very similar because they are both eukaryotic cells. They both contain membrane-bound organelles such as the nucleus, mitochondria, endoplasmic reticulum, golgi apparatus, lysosomes, and peroxisomes. Both also contain similar membranes, cytosol, and cytoskeletal elements.
