Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
cells that contain a true nucleus
A
prokaryotes
B
eukaryotes
C
carbohydrate
D
plant cells
Explanation: 

Detailed explanation-1: -Eukaryotes (meaning ‘true nuclei” where “karyote” is derived from the ancient Greek for “kernel") include fungi, protozoa, eukaryotic algae, and of course plants and animals including ourselves. Eukaryotic cells have a nucleus containing chromosomal DNA bounded by membranes.

Detailed explanation-2: -Eukaryotic cells have a true nucleus, which means the cell’s DNA is surrounded by a membrane. Therefore, the nucleus houses the cell’s DNA and directs the synthesis of proteins and ribosomes, the cellular organelles responsible for protein synthesis.

Detailed explanation-3: -Eukaryotic cells, on the other hand, have chromosomes that are enclosed in a true nucleus, and are therefore separated from the cytoplasm by the nuclear membrane. Eukaryotic cells also have a wide range of organelles that perform specialized functions.

Detailed explanation-4: -The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. The nucleus is where eukaryotes store their genetic information.

Detailed explanation-5: -1. Plant and animal cells are eukaryotic, meaning that they have nuclei. Eukaryotic cells are found in plants, animals, fungi, and protists. They generally have a nucleus-an organelle surrounded by a membrane called the nuclear envelope-where DNA is stored.
