What animal has a nucleus?
Most animal cells (except for human red blood cells and some others) have a nucleus. It is like a control centre in the cell which allows some substances to enter and others substances to leave the cell. It also initiates chemical reactions and processes like respiration in the cell cytoplasm.
Materials enter and leave the nucleus through opening in its?
Materials enter and leave the nucleus through openings called nuclear pores. These pores regulate the movement of molecules, such as RNA and proteins, between the nucleus and the cytoplasm. They allow for communication and transportation of essential components for cellular functions.
What is tissue packed with chloroplasts?
The stomata in the epidermis allow oxygen, carbon dioxide and water vapour to enter and leave the leaf. The guard cells also contain chloroplasts for photosynthesis.
How do large particles enter the nucleus?
Endocytosis, particularly, phagocytosis because the amoeba surrounds the food particle and engulfs it. The food particle is then enclosed into a food vacuole inside the cell where it can be accessed when the cell needs food.
What is the control center in animal cells called?
The control center of a cell is called the 'nucleus'.
What organelle is in charge of cellular functions?
The nucleus is the organelle in charge of cellular functions. It contains genetic material (DNA) that regulates all cell activities by controlling the synthesis of proteins and other molecules essential for cell function.
How do proteins enter the nucleus?
Proteins enter the nucleus through nuclear pores in the nuclear membrane. These pores allow specific proteins to pass through and enter the nucleus where they can perform their functions.
What cell organelle has pores that allow certain molecules to leave and enter it?
Cell membrane

What enters and leaves the nucleus?
Ribonucleic acid (RNA) enters the nucleus to deliver genetic information for protein synthesis, while messenger RNA (mRNA) leaves the nucleus to carry the information encoded in DNA to the ribosomes for protein synthesis.
What organelle do the products of photosynthesis enter?
The answer is chloroplast...
How does mRNA enter the nucleus?
mRNA does not enter the nucleus. It is transcribed from DNA inside the nucleus and then exits the nucleus to carry genetic information to the ribosomes in the cytoplasm for protein synthesis.
What is tissue packed with chloroplasts?
The stomata in the epidermis allow oxygen, carbon dioxide and water vapour to enter and leave the leaf. The guard cells also contain chloroplasts for photosynthesis.
How is the nucleus of a cell separated from the cytoplasm?
The nucleus as a whole is not separated from the cytoplasm, which surrounds it. However, the contents of the nucleus (DNA and assorted proteins) is separated from the cytoplasm by the nuclear membrane (a.k.a the nuclear envelope), which is the outer portion of the nucleus.
