Question

Describe about , Nucleus , mitochondria Golgibody and plastids​

Answer 1

1)The central part of an atom or of certain cells

2)An organelle found in large numbers in most cells, in which the biochemical processes of respiration and energy production occur.

3)A complex of vesicles and folded membranes within the cytoplasm of most eukaryotic cells, involved in secretion and intracellular transport.

4)Any of a class of small organelles in the cytoplasm of plant cells, containing pigment or food.

Answer 2

Nucleus

The nucleus contains genetic material or DNA in the form of chromatin, or, during mitosis or late interphase, chromosomes. All transcription and replication of genetic material takes place within the nucleus, as does RNA processing. The nucleolus also resides within the nucleus, and is responsible for RNA transcription and folding. Translation of RNA transcripts takes place outside of the nucleus.

Mitochondria

A mitochondrion is the organelle responsible for a cell's metabolism. It synthetizes ATP through a protein called ATP synthase. Mitochondria have a double membrane. An outer membrane and a folded inner membrane. The internal membrane, called the cristae is invaginated (folded or creased), to maximize surface area enabling it to hold more ATP synthases. It is called as "the powerhouse of the cell" which is present in the eukaryotic organisms. It has matrix inside the inner membrane.

Golgi complex

The Golgi Complex basically functions as a "packaging center" for the cell, attaching "address labels" (functional groups) to various cell products to direct them to their respective locations, and "packaging" the products into vacuoles to ensure delivery. Anatomically, the Golgi Complex consists of layers of lipid membrane stacked one on top of another, with a cis face and a trans face. As the molecular product being packaged moves through the complex, various enzymes act upon it to induce vacuole formation and functional group attachment.

Golgi bodies lose close to the nucleus.
