Answer:
1. Transcription, Nucleus
2. Translation, Ribosome (Cytoplasm)
Explanation:
All living organisms contains genetic material in their nucleus (for eukaryotes), usually in the form of DNA. The DNA stores the information that encodes the synthesis of useful products (proteins). However, the encoded information needs to be expressed, which is done in two major stages namely: transcription and translation.
Transcription is the first process of gene expression which occurs in the NUCLEUS of eukaryotic cells, since the DNA is located there. Transcription involves the synthesis of a RNA molecule from a DNA template i.e. the information in the DNA is used to produce a RNA.
Translation is the second process of gene expression. In eukaryotes, the RNA transcript moves out the nucleus into the cytoplasm of the cell, where organnelles called RIBOSOME attach to it. In the ribosome, the RNA is used to synthesize amino acid sequence, which eventually becomes a PROTEIN. Hence, the information contained in the RNA molecule is translated into a protein molecule.
Ribosomes are what make up proteins (the protein builders). There are a lot of ribosomes in the cytoplasm.
Explanation: Ribosomes connect mRNA(messenger RNA) and tRNA (transfer RNA) to synthesize polypeptides and proteins. Proteins are made up of building blocks amino acids. Polypeptides are chains of amino acids and portions of proteins in cells.
(Also, ribosomes are usually the small dots that you see in a cell diagram)

"Mangroves live life on the edge. With one foot on land and one in the sea, these botanical amphibians occupy a zone of desiccating heat, choking mud, and salt levels that would kill an ordinary plant within hours. Yet the forests mangroves form are among the most productive and biologically complex ecosystems on Earth. Birds roost in the canopy, shellfish attach themselves to the roots, and snakes and crocodiles come to hunt. Mangroves provide nursery grounds for fish; a food source for monkeys, deer, tree-climbing crabs, even kangaroos; and a nectar source for bats and honeybees.
As a group, mangroves can’t be defined too closely. There are some 70 species from two dozen families—among them palm, hibiscus, holly, plumbago, acanthus, legumes, and myrtle. They range from prostrate shrubs to 200-foot-high (60 meters) timber trees. Though most prolific in Southeast Asia, where they are thought to have originated, mangroves circle the globe. Most live within 30 degrees of the Equator, but a few hardy types have adapted to temperate climates, and one lives as far from the tropical sun as New Zealand. Wherever they live, they share one thing in common: They’re brilliant adapters. Each mangrove has an ultrafiltration system to keep much of the salt out and a complex root system that allows it to survive in the intertidal zone. Some have snorkel-like roots called pneumatophores that stick out of the mud to help them take in air; others use prop roots or buttresses to keep their trunks upright in the soft sediments at tide’s edge. These plants are also land builders par excellence. Some Aborigines in northern Australia believe one mangrove species resembles their primal ancestor, Giyapara, who walked across the mudflats and brought the tree into existence. The plants’ interlocking roots stop river borne sediments from" coursing out to sea, and their trunks and branches serve as a palisade that diminishes the erosive power of waves.
There are pretty obvious differences between plants and animals, but at the chemical level the cells of all plants and all animals contain DNA in the same shape the famous “double helix” that looks like a twisted ladder.
