Do animal cells without mitochondria have cytoplasmic genes

1.Animal cells have mitochondria, and prokaryotic cells have plasmids, which are cytoplasmic genes.

2.Ditto. 3.Mitochondria.

Plant Cells Nazakura Friend: From the outside to the inside.

Cell wall, cell membrane, cytoplasm, nucleus (but also vacuoles, chloroplasts, and mitochondria).

Animal cells: from the outside to the inside.

The cell membrane, cytoplasm, nucleus (and also mitochondria),6, yes, eukaryotic cells all have mitochondria. Except for certain highly specialized cells, such as mammalian mature erythrocytes.

Prokaryotic cells, such as bacteria, do not have mitochondria. Their respiration takes place in the cytoplasmic matrix, and their respiratory enzymes are present in the cytoplasm. ,1,Not necessarily, plants also include some fungi, there are some fungi that do not have mitochondria,0,Mitochondria are the places where cells carry out aerobic respiration, and can also provide energy for life activities.

So humans and animals have mitochondria in their bodies.

But some prokaryotes don't have mitochondria, 0, and the problem is too broad for humans to have mitochondria.

Animals and plants are not necessarily animals -- paramecium, for example, are unicellular animals that don't have mitochondria.

Plants such as cyanobacteria and Candida do not have mitochondria, but they can all breathe, 0, mammalian cells (including humans) have mitochondria, but not all cells have, for example, mature red blood cells do not. Also, other animals do not necessarily have mitochondria, for example, roundworms do not have. Higher plants do not have mitochondria in their ductal cells, and some lower plants do not contain mitochondria, such as cyanobacteria (prokaryotes, but they are algae, so they are plants).

Organisms such as roundworms, cyanobacteria, and bacteria do not contain mitochondria. If you don't have it, you don't have it, just like why people have mitochondria (probably because they are still relatively low). Also, who said there are no mitochondria.

0, refer to the explanation of wikipedia: mitochondria are organelles present in the cells of most eukaryotes (including plants, animals, fungi and protists) in cell biology. Some cells, such as the protist trypanosomes, have only one large mitochondria, but usually there are hundreds or thousands of them in a single cell.

In other words: eukaryotes almost all have mitochondria, and prokaryotes almost have no mitochondria. Biology is ambiguous, it doesn't define itself.

Of course, high school textbooks assume that eukaryotes have mitochondria, and prokaryotes do not have mitochondria. The protists mentioned above are unicellular eukaryotes...0, Mitochondria is present in every cell, and it can help sustain life.

Even anaerobic bacteria have mitochondria. ,0,Do human and animal cells contain mitochondria?

RT Which organisms do not have mitochondria in their cells? Why? (Do they need to breathe and convert organic matter into energy?)

Animals and plants need to live and carry out activities, they must be mitochondria, and the paramecium, which is mitochondria, and the answer of the answer to the juvenile face is inaccurate.

Answer: Mitochondria is an organelle with a double-layer membrane structure, and the liquid part in the mitochondrial inner membrane belongs to the matrix, so the mitochondrial matrix does not belong to the cytoplasmic matrixCytoplasm is divided into cytoplasmic matrix and organelles.

It has been observed that a cell contains centrosomes and vacuoles, and the organism with such cells is most likely: aCorn B

Onions ...Cytoplasmic matrix BMitochondrial matrix C

Chloroplast matrix DRibosomes 3The following chemical reactions in the cells of the human body are deficient.

For eukaryotes, cytoplasm refers to the part of the cell membrane other than the nucleus. Including stability. Cytoplasmic Ascending Matrix (Anaerobic Respiration and Aerobic Respiration Phase 1) Mitochondria (Energizing) Ribosomes (Interphase Proteins.

The following commonalities that do not belong to the cytoplasmic matrix, chloroplast matrix, and mitochondrial matrix are ( )aBoth contain DNA BWith the transfer of compounds in living organisms, the following errors in their analysis are ( )ah] via to Portugal.

October 20, 2020 - The substance that transports amino acids to ribosomes is transporter RNA (tRNA), which is present in the cytoplasmic matrix and nucleus. Fluorescent bleaching recovery technology has important applications in cell biology and consists of three steps: green fluorescent.

Nov 13, 2016 - The endosymbiosis hypothesis states that mitochondria** are superior to aerobic bacteria that are engulfed by primitive pre-eukaryotes; This fine. Such as enzymes, antibodies, hormones and components of the extracellular matrix, etc.; Membrane proteins, including the cytoplasmic membrane to carry the endoplasm.

It must not be an aerobic respiration animal, which does not use mitochondria, such as parasites, for anaerobic respiration.

Mitochondrial genome of plant cells.

The mitochondrial genome of plant cells varies greatly in size, the smallest is about 100 kb, most of them are composed of non-coding DNA sequences, and there are many short homologous sequences, and DNA recombination between homologous sequences will produce smaller subgenomic circular DNA, which coexists with the complete "main" genome in the cell, so the study of plant mitochondrial genome is more difficult.

Mitochondrial genes of mammals in this segment.

The mitochondrial gene DNA of mammals has no introns, and almost every pair of nucleotides is involved in the composition of a gene, and the sequences of many genes overlap.

Simply 1. One big and one small.

2。One fine and one miscellaneous.

There is no essential difference.

Mitochondrial DNA has a large number of highly repetitive sequences, which are species-specific. Animals and plants are quite different. But this can only indicate that the two are distantly related. There is still no essential difference in DNA.

There is basically no difference. They are all places that provide energy to biological cells.

There really is no essential difference, except for the number of genes and the size of the mitochondrial genome.

DNA contains deoxyribose, RNA contains ribose.

Photosynthesis is carried out in chloroplasts to synthesize glucose, while mitochondria carry out the second and third steps of aerobic respiration, starting with the breakdown of pyruvate, without glucose.

Glycogen is in animal cells, cellulose is in plant cells, maltose is in plant cells, and starch is in plant cells.

So choose: D

Obviously, choose D

DNA, deoxyribose + phosphate + base; RNA, ribose + phosphate + base.

chloroplasts, which can make glucose through photosynthesis.

starch, which is only found in plants; In animals, it is glycogen.

Mitochondria are mostly from the maternal line, but mainly mitochondrial DNA does not contain histones, is not a chromosomal structure, and is free of combustion cavities. DNA in mitochondria, chloroplasts, and plasmids is single-stranded circular. Whereas, DNA in the nucleus is double-stranded.

It has been suggested that the DNA in mitochondria, chloroplasts, and plasmids evolved from ancient times due to the evolution of some kind of bacteria that lived in symbiosis with other single-celled organisms in ancient times. Therefore, its DNA is not the same as the DNA of the cell itself.

Animal cells mostly have mitochondria. Except for some highly specialized cells, such as mammalian mature erythrocytes, there are no organelles such as mitochondria. Mitochondria is a two-layer membrane-coated organelle present in most cells, a structure in cells that produces energy, and is the main site for cells to perform aerobic respiration.

Mitochondria. Mitochondria are globular, rod-shaped or filamentous particles of various sizes, generally 1-2 m long, which can be distinguished by special staining under a light microscope. In animal cells, mitochondrial size is limited by the level of cellular metabolism.

Different tissues and different conditions may produce abnormally enlarged mitochondria, called "giant mitochondria": up to 10-20 m in exocrine pancreatic cells; The size of mitochondria in neuronal cell bodies varies greatly, and some may be up to 10 m long; The mitochondria of human fibroblasts are longer, up to 40 m. Studies have shown that the mitochondria of some plants such as tobacco can reversibly transform into giant mitochondria up to 80 m in length and form a network in an environment with low oxygen partial pressure.
