Do animal cells have chromatin
WebThis combination of DNA and proteins is called chromatin. In eukaryotes, chromosomes are linear structures. Every species has a specific number of chromosomes in the nucleus of its body cells. For example, in humans, the chromosome number is 46, whereas in fruit flies, the chromosome number is eight. WebThe nucleoplasm includes the chromosomes and nucleoli. Many substances such as nucleotides and enzymes, which direct activities that take place in the nucleus are dissolved in the nucleoplasm. The soluble, liquid portion …

The major difference between plant and animal cells is that plant cells have a cell wall and chloroplasts. Do animal cells have a chloroplast? Chloroplasts are the food producers of the cell.
WebA lysosome is a membranous sac of hydrolytic enzymes that an animal cell uses to digest (hydrolyze) macromolecules. The pH range inside a lysosome is acidic. One function of lysosomes is intracellular digestion of particles engulfed by phagocytosis. Describe this process of digestion. What human cells carry out phagocytosis? WebJessica McGregor. There are 13 main parts of an animal cell: cell membrane, nucleus, nucleolus, nuclear membrane, cytoplasm, endoplasmic reticulum, Golgi apparatus, ribosomes, mitochondria, centrioles, cytoskeleton, vacuoles, and vesicles.
