Many people think that plant cells do not contain mitochondria, but of course they do! Mitochondria are needed to release energy from sugar, plant cells need this energy to function just as animal cells. Plant and animal cells are different because A: plant cells do not have a nucleus or mitochondria B: animal cells do not have DNA or ribosomes C: plant cells do not have a cell membrane D: animal cells do not have a cell wall or chloroplasts I think the answer is C. 2020-06-19 · 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.

However, they have some apparent differences. Firstly 1. Plant and animal cells are eukaryotic, meaning that they have nuclei. Eukaryotic cells are found in plants, animals, fungi, and protists.

The nucleus is perhaps the most important structure inside animal and plant cells. It is the main control center for the cell and acts kind of like the cell's brain.

Because of the control of all biological functions of the nucleus cells (eg metabolism, cell division, boom and circulation of hereditary properties), it is also called the cell brain. In the primordial cells, the prokaryotic cells do not have a nucleus coating, so the genetic material or chromatin substance stays in the DNA cytoplasm.

Also Know, do mature cells of xylem have nucleus?

The nucleus is where DNA is housed in the cells of plants. A nucleus consists of the cell’s DNA and a nucleolus which are surrounded by a double membrane. The double membrane that surrounds the nucleus is called the nuclear envelope. All cells contain DNA, as described above. However, plant cells, which are eukaryotic, contain organelles and a nucleus while prokaryotic cells do not possess organelles or a membrane bound nucleus. We will start by going over the structures that are unique to all eukaryotic.

The nucleus is enclosed by the nuclear membrane, which has pores for the passage of RNA and proteins.

2020-03-02 · These cells contain many more 'parts' than an animal cell, and a classic exam question is to compare animal and plant cells. All plants are eukaryotic - they have a nucleus and other membrane bound organelles. Plant cells contain almost all of the organelles found in animal cells but have several new ones to help them survive.

Plants are the monokaryotic cells, which possess an individual nucleus. A well-developed nucleus is only found in the advanced or multicellular organisms, those having division of labour. The function of the nucleus in the plant cell is to store the plant's DNA and control the activity of the cell through protein synthesis.
