In the high school stage, it is not considered to be an organelle.
But at the college level, the nucleus is an organelle.
Just like the concept of chromosomes, in college, chromosomes are generalized, and it can be said that the chromosomes of bacteria are duplicated, but in high school, the same cannot be said.
High school is a beginner stage after all.
-
No, the organelle of plant cells: mitochondria. Chloroplasts, Golgi apparatus, endoplasmic reticulum, ribosomes, vacuoles, lysosomes, etc.
Organelles of animal cells: mitochondria. Golgi apparatus, endoplasmic reticulum, ribosomes, lysosomes, etc.
-
In your high school textbook, the nucleus is not an organelle. But in cell biology, the nucleus is an organelle. If you study biology at university in the future, you will know it, and you can also look at the textbooks on cell biology.
-
The nucleus is not an organelle.
I used to make mistakes in the book, but now I have changed it.
-
The nucleus does not belong to organelles and is a separate category. But it is easily confused with ribosomes, endoplasmic reticulum, and their metabolism produces water.
-
No. Organelles belong to the cytoplasm and are not at the same level as the nucleus.
-
Eukaryotic cells have organelles. Organelles are distributed within the cytoplasmic matrix and are subcellular structures with certain structures and functions. Various types of organelles are related in structure and origin. Organelles that are of great significance for living cells to complete various life activities ---.
The nucleus is the largest organelle inside the cell!
-
Generally speaking, eukaryotic cells are mainly composed of the nucleus, cell membrane and cytoplasm. The cytoplasm is divided into cytoplasmic matrix and organelles, and the nucleus can be divided into nucleolus, nuclear membrane and nuclear pore.
-
No, the nucleus, organelles, and membranes are juxtaposed.
-
No, it belongs to the cellular structure.
-
The cytoplasmic matrix and organelles make up the cytoplasm and cytoplasm and nucleus and so on make up the cell and therefore not.
I believe that the current textbooks are correct, at least the exams will not be wrong.
-
The nucleus is not an organelle.
-
The nucleus is not counted as an organelle because organelles are microstructures in the cytoplasm that have a certain structure and function. The organelles in the cell mainly include: mitochondria, endoplasmic reticulum, centrosomes, chloroplasts, Golgi apparatus, ribosomes, etc.
They make up the basic structure of the cell and enable the cell to work and function normally.
The size of the nucleus varies from species to species, for example, the diameter of the nucleus of higher animals is generally 5 10 microns, the diameter of the nucleus of higher plants is generally 5 20 microns, and the diameter of the nucleus of lower plants is generally 1 4 microns.
-
Middle school doesn't count, college does.
-
Until now, the nucleus is not counted as an organelle. There are a total of eight types of organelles, which are ribosomes, endoplasmic reticulum, Golgi apparatus, lysosomes, vacuoles, centrosomes, mitochondria, chloroplasts.
-
It is considered an organelle at the college level, and it is not considered an organelle at the middle school level.
-
The nucleus is the largest and most important organelle in a cell
-
Be. Nucleus is the largest and most important cell structure in eukaryotic cells, the regulatory center of cytogenetics and metabolism, and one of the most significant markers that distinguish eukaryotic cells from prokaryotic cells (very few eukaryotic cells have no nucleus, such as mammalian mature red blood cells, higher plant mature sieve cells, etc.).
The old textbooks of junior high school, high school textbooks or some foreign textbooks believe that the nucleus is not an organelle, and the university cell biology considers it to be an organelle, which is mainly composed of nuclear membrane, chromatin, nucleolus, nuclear matrix, etc.
-
It does not belong to the scope of the college entrance examination, but after arriving at the university, with the different positioning of the organelles, the nucleus can be regarded as the organelle with the most in the cell.
-
It doesn't belong
Cells are generally divided into three parts: cell, cytoplasm, and nucleus.
The organelles you mentioned exist in the cytoplasm, such as mitochondria, chloroplasts (plants), ribosomes, etc., all belong to organelles, so the cytoplasm includes organelles and cytoplasmic matrix.
The nucleus that you're talking about is not an organelle structure, it's just a major storage and replication site for genetic material
-
The nucleus is the largest and most important organelle in the cell (the old junior high school textbook believes that the nucleus is not an organelle, but the university cell biology considers it to be an organelle. In fact, many of the things we learn in middle school are not very accurate, which is different from what is taught in college, if you are a middle school student, you will not belong to organelles.
-
It doesn't belong
The main organelles in the cell are: mitochondria, endoplasmic reticulum, centrosomes, chloroplasts, Golgi apparatus, ribosomes, lysosomes, vacuoles, etc.
Note: It is not in the high school textbook. When it comes to college textbooks, it belongs to organelles.
-
Of course it belongs to the organelles.
-
The nucleus is not an organelle:
The nucleus is not an organelle.
The cell is composed of the cell membrane, cytoplasm and nucleus (plants also have a cell wall), so the nucleus and cytoplasm are juxtaposed, and the cytoplasm includes a finely closed and clear cytoplasmic matrix (colorless 1Transparent colloidal substance) and organelles, so the nucleus is not an organelle, organelles include endoplasmic reticulum, ribosomes, Golgi apparatus, lysosomes, mitochondria, chloroplasts, positive bonds and vacuoles, etc., excluding the nucleus, the nucleus is the most important structure in the cell, surrounded by the nuclear membrane to form a nuclear membrane with nuclear pores (for biological macromolecules to pass through), the nuclear membrane contains nucleoli and chromosomes, the nucleus is the place where genetic material is stored and reproduced, and it is the control center of cell genetic characteristics and metabolic activities.
-
The nucleus is not an organelle because the organelle is a part of the cytoplasm. The cytoplasm and the nucleus are parallel structural levels, so the nucleus is not an organelle.
The main structure of the nucleus is the nuclear membrane, which is a double-layer membrane that completely encloses the nucleus, which can separate the substances in the membrane from the cytoplasm and the reticular nucleus layer with cytoskeletal functions. Since most molecules cannot directly penetrate the nuclear envelope, nuclear pores are required as passageways for substances to enter and exit.
These pores allow small molecules to permeate ions freely; Molecules as large as proteins, on the other hand, need the help of carrier proteins to pass through. Nuclear trafficking is the most important function in a cell; Gene expression and chromosome preservation depend on transport at the nuclear pore.
Organelles are generally considered to be microstructures or microorgans that are scattered within the cytoplasm and have a certain form and function. However, there are some differences of opinion on the scope of the term "organelle". The organelles in the cell mainly include:
Mitochondria, endoplasmic reticulum, centrosomes, chloroplasts, Golgi apparatus, ribosomes, etc. They make up the basic structure of the cell and enable the cell to work and function normally.
Absolutely. There are chromosomes in the nucleus, and there is DNA on the chromosomes, and DNA is the genetic material.
There are two main differences.
First, cytoplasmic genes are passed from mother to offspring. The nuclear genes are half of the mother and half of the parents. >>>More
Yes, nucleolus.
The site has rRNA, ribosomes. >>>More
Platelets, also known as thrombocytes, are megakaryocytes in the bone marrow. >>>More
The nucleus is the genetic information bank of the cell, the chromosome is the substance in the nucleus that is easy to be dyed dark by basic dyes, and the chromosome is composed of two substances: DNA and protein; DNA is the carrier of genetic information, mainly found in the nucleus, and the DNA molecule is a double helix structure, like a spiral-shaped ladder; The small unit on the DNA that determines the traits of the organism is called the gene The gene determines the trait of the organism A chromosome is composed of a DNA molecule, and there are many genes on a DNA molecule Therefore, the relationship between the nucleus, chromosomes, DNA, and genetic information can be summarized (as shown in the figure) as follows: >>>More
