Answer 1

The Nucleus

Explanation:

Both plant and animal cells are eukaryotic, so they contain membrane-bound organelles like the nucleus and mitochondria. The nucleus of eukaryotic cells is similar to the brain of the cell. It contains the genetic information (DNA) and directs the cell how to function.

However, plant cells and animal cells do not look exactly the same or have all of the same organelles, since they each have different needs. For example, plant cells contain chloroplasts since they need to perform photosynthesis, but animal cells do not. Plants and animals are very different on the outside as well as on the cellular level.

Both animal and plant cells have mitochondria, but only plant cells have chloroplasts. Plants don’t get their sugar from eating food, so they need to make sugar from sunlight. This process (photosynthesis) takes place in the chloroplast. In order to do photosynthesis, a plant needs sunlight, carbon dioxide (CO2) and water. Once the sugar is made through photosynthesis, it is then broken down by the mitochondria to make energy for the cell. Because animals get sugar from the food they eat, they do not need chloroplasts: just mitochondria.

Answer 2

Answer:

Genes in plants and animal cells are present in the nucleus.

Explanation:

• The bacterial cell is prokaryotic so, genes are freely located in the cytoplasm makes up the nucleoid but plant and animal cells fall under the category of eukaryotes, they have bounded genetic material.
• The genetic material is made up of DNA and remains as chromatin in the nucleus.
• The nucleus is a membrane-bound organelle having a double membrane, nuclear pores, nucleosome and chromatin threads. It is equivalent to the powerhouse of the cell.
• Genes are present in the form of chromatin thread which later condenses to form chromosomes and divides into the daughter cell apparatus by a series of events.
• Bacterial cells divide the genetic material into the offspring as it is but in plants and animals crossing over and recombination of genes takes place.
